Can a broken spine be repaired?


[Youngjun Ham's mind PT] How Fixed the Broken Spine Without Surgery(chosun.com)


# If you were hit by a car traveling at 90 kilometers per hour and suffered a fractured vertebrae, would you believe that you healed naturally through meditation without the help of modern medicine?

It actually happened, and she wrote about it, became a best-selling author, and an educator and entrepreneur sharing her natural healing methods with the public.

Joe Dispenza (1962-) was 23 years old in 1986 when he was riding his bike in a triathlon and was hit by an SUV and thrown to the pavement. Multiple spinal compression fractures. Six vertebrae were broken and twisted, and if she didn't have surgery within three days, she would be paralyzed for life. The surgery involves placing a 20- to 50-centimeter-long steel rod (Harrington rod) in her spine, and even if she heals, she will have a hard time living a normal life.

After much deliberation, he decided against the doctors' suggestion and decided to take matters into his own hands. In fact, Dr. Dispenza was already running a clinic in Southern California as a chiropractic specialist who uses spinal manipulation to heal without drugs.

A form of sports medicine, chiropractic is a manual treatment of abnormalities in the nervous, muscular, and skeletal systems, based on the premise that all disease stems from compression of the spinal nerves due to vertebral misalignment. In other words, Dispenser was an expert when it came to his back. What's more, he had been practicing martial arts and yoga for a long time.


Eam Taekyoung : Chiropractic believes that all diseases stem from pressure on the spinal nerves due to vertebral deviation. I believe that posture, stress, and food are the roots of all diseases, including cancer, except those caused by viruses. I also believe that almost all degenerative diseases, such as lung disease, cardiovascular disease, brain disease, and neurological disease, are caused by long-term accumulation of forward head protrusion and V-shape footed walking. 




He was a firm believer in the body's natural ability to recover. The ability of the body to heal itself is the philosophy of chiropractic and the theoretical foundation of holistic practitioners.

The power that created the body heals the body." He was discharged from the hospital and began his rehabilitation in a bright room at a friend's house.

At first, he ate little raw food. This was so that much of the energy used for digestion could be better used for wound healing.

I meditated and self-hypnotized for an hour three times a day, morning, noon, and night. In my mind's eye, I pictured each vertebra in my spine and envisioned a perfect spine. He also practiced reiki, a common practice in Eastern medicine. She would place the hands of visiting relatives on her wounds to channel their unconscious energy.

Finally, I applied physical stimulation to the wound to replenish the calcium in the broken bones. An inclined table was placed next to the bed, and he carefully rolled over, constantly stimulating his spine.

After six weeks, I started swimming, feeling my body recovering quickly. At first, I floated on top of the water while lying on a chaise longue, wearing thick clothes that immobilized my body. Later, he learned to float in the water and then stand, and later he was able to swim with his whole body.

By week 8, he was able to crawl on bare ground and progressed to walking, sitting, and bathing on his own. By week 12, he was able to lift dumbbells and finally walked for an hour on his own, no longer needing therapy.


# The key here is his meditation and self-hypnosis. He spent three hours a day visualizing his bones fusing and healing in his head. This is the kind of "mental rehearsal" that athletes often do. It takes a lot of mental focus and energy. Eventually, he overcame his illness and became a "meditation evangelist".


Eam Taekyoung : I think the above spinal imagery, mental rehearsal, or mental vision can be explained more scientifically as 'neurosensory perception' and 'attentional concentration effect'. 

Postural Science: Perceiving body specificity through neurosensory isokinetic tornado flight


His book, [You Are the Placebo] became a New York Times bestseller and has been translated into Korean. He travels the U.S. and around the world giving lectures, courses, and testimonials of people who have been healed of mental and physical illnesses by him. His $2,299 retreats sell out in a matter of days.

While he has many supporters, critics call him a "pseudoscientist who sells meditation as a cure-all," and the mainstream U.S. media hasn't taken him seriously.


# But when you take a closer look at his theories, they don't seem too far-fetched.

Perhaps the reason he is criticized is that he claims many of the theories already published in neuroscience, brain science, epigenetics, and quantum physics as if they were his own scientific theories, and sometimes he seems to make money by "cosplaying" as a spiritual guru.

In any case, the idea that we can create a new life by changing our minds and brains with our own consciousness, beyond our genes and environment, is hopeful in today's complex world.

In the end, his story is in line with the old saying, "If you have an intellect, you have a heart. It also reminds me of the saying that the "Iron Lady," former British Prime Minister Margaret Thatcher (1925-2013), lived by since she was a child.

"Thoughts become words, words become actions, actions become habits, habits become character, and character becomes destiny."

Relationship between Step count, Arm shape, and NFSM


Natural Foot Steps per Minute (NFSM) is the number of steps per minute that you walk naturally without bending your elbow. It's a simple pendulum, like a wall clock or a Viking ride.

This number depends on the length from the center of your palm to your shoulder joint. A first-grade child with an average arm length of about 0.4 meters would have an NFSM of 95, while an adult with an arm length of about 0.55 meters would have an NFSM of about 81.



When the number of steps taken is greater than the NFSM, the elbow begins to bend as the arm moves forward, and the faster you walk, the more the elbow bends.

When you run, your elbows are typically bent at about 90 degrees or less, and the faster you run, the smaller the angle.

When walking slower than the NFSM, the elbow does not bend, but a rotational component is added to the linear motion of the hand. The slower you walk, the greater the rotational component.

Diaphragm and Posture

* The anteroposterior distance (L) of the diaphragm decreases as the angle of posterior tilt of the thoracic spine relative to the lumbar spine increases.


* The shorter the anteroposterior distance (L) of the diaphragm, the greater the upward and downward travel of the diaphragm during breathing, which can increase the volume of thoracic breathing.


* A posterior tilt of the thoracic spine, similar to that of a runner, activates thoracic inspiration by lifting the ribs upward and then downward.


* Moving the thoracic spine backward relative to the lumbar spine reduces the abdominal space, somewhat restricting abdominal breathing.   




Arm Strokes and Posture


1. Principles of Pendulum Oscillation 

  - The time it takes for a pendulum to travel one cycle is only affected by the distance(L_p) between the origin and the pendulum. The weight of the pendulum has no effect.

  - The maximum stroke speed of the pendulum (V_c) is determined by the maximum height of the pendulum motion (h_max).





2. Arm motion

  - The total length of the arm and the angle at which the elbow is bent determine the natural duration of the arm's one-cycle pendulum motion. This can be altered by intentionally applying force to the arm muscles. 

  - The maximum height of the arm as it retracts determines the maximum speed of the arm's stroke.

  - When running, the distance(L_p) between the origin and the pendulum is reduced by bending the elbows a lot to shorten the one-cycle oscillation time.



3. Postural deformity involving the arm strokes

  - Differences in the force applied to the muscles of the two arms, the maximum retraction height (h_max), and the elbow bend angle cause differences in the left and right stroke distance of the arms.

  - Persistent and excessive differences in these forces, heights, and (or) angles are manifested as a tilt of the shoulder line and a difference in left/right arm stroke distances .

What Is a Full Recovery Workout?

 

When I go for a walk, I often see people dressed up in workout clothes and running. However, there are aspects of their workouts that seem to me to make their bodies worse as much as they make them healthier.   

A surprising number of people run while looking at the ground, or with an unbalanced left/right foot or arm stroke. 


I believe that people need to change their definitions of labor, exercise, and rest in order to not leave their happiness to fate. 

* Definition of work: any activity that keeps the thoracic space constricted or can cause it to constrict in the long term.

* Exercise: activities that maintain an expanded chest space or contribute to a long-term expansion of the chest space.

* Definition of rest: activities that maintain or contribute to a state of relaxed muscular and emotional tension.


Runners who run with their eyes on the ground, or who run with an unbalanced left/right foot or arm stroke, are clearly getting a workout, but the workout is not contributing fully and positively to their body and mind. Running in this posture qualifies as an activity that is both exercise and labor, based on my redefinition of exercise and labor. It's certainly better than not exercising at all, but the long-term negative effects are likely to be significant.

In order to be fully restorative, you need to pay attention to your running form so that it doesn't include any active aspect that could reduce your chest space or constrict it in the long run.

The need for postural awareness training


Is aging a disease?

The International Health Organization (WHO) has included aging as a preventable and treatable disease in its 2018 International Classification of Diseases-11 (ICD-11) statistical classification of diseases, giving it a disease code. 

Aging is not a disease. Aging is a swamp that begins at birth. If you don't flounder in the swamp, you slowly sink, so you just extend the time that you have a life. If you keep your arms and legs open when you're in the swamp, you'll go down slowly.

To live longer in the swamp of aging, we need to reduce our sluggishness in the areas of posture, stress, and food. Secondarily, we can consider taking anti-aging drugs. 

However, we unintentionally determine the length of our lives primarily through slouching, eating too much food, and exposing ourselves to low-intensity but persistent stress. Slouching puts pressure on the respiratory and cardiovascular systems, excessive food intake makes the entire body system lazy, and stress makes the body overly rigid.

Aging is not a disease that can be cured, but a swamp whose end can be controlled. No one can escape it, so there's nothing to fear.




The need for postural awareness training

People are generally unaware of their postural deformity until it reaches a serious state. They find it difficult to objectively observe their relatively mild postural deformities. People are also generally unaware of the effects of postural deformities on their bodies and minds. 

It usually develops slowly, almost imperceptibly, and gains momentum in the second half of life. From there, they become more and more aggressive, so It's as if you know or as if you don't know. But after all, you don't know.

To avoid this fate, postural awareness training is essential. Knowing which parts of your body you can detect the difference in feeling when you're upright, slouching forward, leaning to the side, walking with your back muscles disengaged, and so on, allows you to take preventive and restorative measures. However, there is virtually no information out there about this.

I can't say for sure when that time will come, but sooner or later (?) I will definitely educate the public. 

If you can distinguish the sensations caused by your posture, it will be relatively easy to detect the changes that food causes in your body and the changes that stress causes in your body and mind. So, I think we need posture awareness education first. It is an education on how to take control of your own physical and mental health, how to take control of your own happiness instead of leaving it to fate.

Perceiving body specificity through neurosensory isokinetic tornado flight

Overview

When a specific body part is in an abnormal state (blood circulation, muscle stiffness/relaxation/damage, etc.), neurosensory sensations are perceived differently in the brain. By perceiving your own individual body parts with your eyes closed, you can identify the specificity of neurosensory perception of parts that are in abnormal states in the short and long term.

In this method, you first close your eyes and imagine a virtual body that exists in the same size and position as your real body. Then, your visual focus flies inside your body in an isokinetic spiral path. During this process, areas of the body that are in an abnormal physical state will experience neurosensory resistance to the movement of this visual focus, which is detected by the brain. The areas where this neural resistance is perceived are judged to be in an abnormal state in terms of blood circulation, muscle stiffness/relaxation/damage, etc.  

This neural resistance can detect not only when the body is in an abnormal state in the short term, but also the activity of neural structures with different degrees of development according to the principle of neuroplasticity in the long term. Repeated efforts to penetrate the visual focus into the abnormal part of the body where the resistance is occurring can also trigger a healing effect by creating an attentional focusing effect, which to some extent improves blood circulation and increases neural activity.




Specificity Detection Procedure

1. while sitting or standing upright, close my eyes and visualize an imaginary body of the same shape as the real one, with my consciousness envisioning my entire body in the same position where it actually exists. 

2. the imaginary visual focus flies at a constant rotational speed from the bottom to the top inside the body conjured from above.



3. During this process, you may encounter areas of resistance where you feel the visual focus slowing down or bouncing back. This is the area where the nerve cells are in an abnormal state due to muscle contraction or poor circulation, which is what we are looking for. Muscle contraction means that the muscle cannot relax and remains tense.

4. While continuing to try to bring your visual focus to the area of resistance, deliberately contract/relax the muscles around this area in small increments. Change your posture slightly. At some point, the resistance will weaken or disappear and you will be able to regain your airspeed (this is similar to what happens when a big social issue breaks out and the media focuses attention on it, resulting in a significant improvement). 

5. Continue flying to the next area while maintaining the attitude that caused the drag to disappear. 

6. repeat steps 4 and 5 above to fly to the crown of the head, eliminating subsequent areas of resistance. Most people will feel their spine extend at some point during this process.

7. Afterward, open your eyes and look at the position you are in. If you've followed the instructions above, you should find that your head is at a gaze angle of about 40 degrees or more. 

8. You can judge the degree of poor posture in that area by the strength of the resistance you felt during the above process.




Healing Activity Procedure

1. while sitting or standing upright, close your eyes and visualize an imaginary body of the same shape as the real one in the same location as the specific body part where resistance was perceived above in your consciousness. 

2. If the imaginary visual focus attempts to fly at a constant speed of rotation from the bottom to the top inside the specific body part imagined above, resistance is again perceived. As you continue your visualization of this area, deliberately contract/relax the muscles around this area in small increments. Change your posture slightly. At some point, the resistance will weaken or disappear, and you will be able to regain airspeed (this is similar to what happens when a big social issue breaks out and the media focuses attention on it, resulting in a significant improvement). 

3. Take a break.

4. repeat steps 1-3 a few times (If the body is in a very bad condition, it may take several months (several times a day) of practicing the above steps 1-3 to have a meaningful effect)).

6 Principles of Organismal Evolution

Organisms, or living things, have three general features that distinguish them from non-living things: independent self-replication, independent energy conversion, and independent homeostasis. A cultural organism must have the ability to multiply its members independently, produce and consume goods independently, and protect the cultural organism and its members independently. 


1. The Principle of Optimal Efficiency (Principle of Survival)

For animals moving on the ground, the direction of evolution to higher life was to minimize the moment (force to rotate around a point) generated by the body during energy-acquisition activities. The direction was toward full UPRIGHTNESS. This can be described as the pursuit of optimal efficiency in energy acquisition/consumption. Flying and swimming animals continue to optimize for streamlining to minimize the resistance of the fluid. Note that "pursuit" here does not mean pursuit as a direct act of will. When we look back at the results of the interaction of natural selection and rare leaps (mutations), we observe trends that can be interpreted as "pursuit".


2. The Principle of Instability (Principle of Birth)

Instability is the driving force behind the evolution of life and social organisms (organizations, companies, nations, etc.). Nobel Laureate in Chemistry Ilya Prigozhin said: "Irreversibility leads to instability, instability gives rise to self-organization, and self-organization gives birth to life." By the same principle, desire (irreversibility) leads to chaos (instability), chaos (instability) leads to the will to change (self-organization), and the will to change (self-organization) leads to new societies (life). The deepening of instability also means the growth of positive potential to conceive new life or a new society within the negativity.


3. The Principle of Aging (Principle of imbalance)

The deepening speed of 'excess of energy accumulation' and 'energy distribution imbalance' is the speed of aging of individual life or individual social organisms.
Harvard University biologist Bernd Heinrich says, “Eating excess calories means growing faster, maturing faster, and thus shortening one's lifespan.” It is the driving force that triggers instability.


4. The principle of Imitation (Principle of learning)

The physical and social structures of human society have evolved to more precisely mimic the human body and mind (brain), and will continue to do so in the future!

In Winthrop Kellogg's experiments, the only thing his son did better than a young chimpanzee was imitation. Human babies born immature survive better than other animal babies born more mature through imitative learning.


5. The Principle of Metacognition (The Principle of Hope)

All living things walk their own path to optimal efficiency. However, the path can be classified into two paths. The first path is to comply with the ‘will’ of selfish genes (blueprints) to survive and reproduce. The second path is to overcome this genetic will through metacognition. Metacognition can be broadly divided into cognitive expansion of one's scope and deepening of understanding of one's reality.
Who am I? I am, through the interaction between the automatic control mode of the egocentric 'brainstem (life-sustaining activity) & limbic system (emotion)' and the thought control mode (thinking) of the neocortex based on reflective power, a being who controls my body and mind. I recognize and analyze 'the outside and me' through mainly experiences and partially speculations, and based on this, I can change my control program large or small.
My current control program is the result of the interaction between 'experiences & specualtions from the past to the present' and 'past control programs which are continuous but momentarily different'. The control program is programmed according to the 'Neuroplasticity principle' in which nerves related to body parts that are used frequently develop more and nerves related to body parts that are used less often degenerate.
'The principle of metacognition' is that even the remotest possibilities sometimes come true when hoped for. It is a path that goes against the second law of thermodynamics.​ Shakyamuni (estimated 560 BC ~ 480 BC), who understood the reality of the quantum mechanical universe through thinking alone, and Socrates (died February 15, 399 BC), who said, “Know thyself!” Speech can be seen as the formal starting point of metacognition and social evolution.
As an organism, humans are weak in resisting the inertia caused by the principle of optimal efficiency, which is the pressure exerted by selfish genes. Therefore, the majority tend to live a life of an irresistible fateful path toward a faster 'death' by being faithful to the principles of aging.
The evolution of life and society has always been achieved through natural selection and mutation (leap). Therefore, there is the possibility of mutating into a new species through the action of the ‘principle of instability’, which is determined by the extent and speed at which the principles of metacognition are accepted. At the point before the mutation occurred, mutations that occurred later were always completely impractical. The current Earth society cannot be imagined from the time eukaryotes appeared about 2 billion years ago. The beginning and end of metacognition are human posture, breathing, desires, and fears.


6. The principle of Connection (principle of social organism)

Culture is a variety of pursuits that occur in organic associations at a speed that genetic evolution cannot capture. Genetic evolution occurs through natural selection and mutation. Various pursuits occur in directions believed to conform to the desire to improve survival and reproductive capacity. Just as a sonic boom occurs when an object moves faster than the speed of sound, culture is a pursuit that goes beyond the speed of genetic evolution.
In particular, humanity has expanded the scope of connectivity in proportion to the development of transportation and communication methods. The invention of the steam locomotive became the starting point for humans to be liberated from physical labor, and the spread of smartphones is the starting point for humanity to move toward a sedentary society. As transportation and communication develop, the scope of 'social us' in human society has expanded and connectivity has deepened. It will continue to be so! We are moving towards a global organic society.

Definitions of Gaze angles and Ideal front gaze posture


Definition of the 'Vertical face gaze angle'

The angle between the gaze line and the horizon plane when the pupil is located in the center of the eye.


Definition of the 'Horizontal face gaze angle'

The angle between the gaze line and the vertical plane when the pupil is located in the center of the eye.


Definition of the 'Pupil gaze angle' 

The angle between the virtual gaze line when the pupil is located in the center of the eye and the present gaze line when the pupil is turned.



Definition of the 'ldeal front gaze posture'

The body posture when standing with the calf tilted forward about 12 degrees and the moment caused by the CG of the head is zero(the position of the head's CG is on a vertical line from the center of the malleolus connection line of both feet), and both vertical & horizontal face gaze angles are 0(zero) degree.

Slouched posture and its relationship to breathing

Q(Eam Taekyoung) : Is the up and down movement of the diaphragm restricted when sitting in a chair in a slouched position?

A(ChatGPT) : When sitting in a slouched position in a chair, the movement of the diaphragm can be somewhat restricted compared to sitting in an upright posture. The diaphragm is a dome-shaped muscle located at the base of the ribcage, and it plays a crucial role in the process of breathing.

In an upright position, the diaphragm has ample space to contract and move downward during inhalation, allowing the lungs to expand fully and take in an adequate amount of air. However, when slouching in a chair, the forward bending of the upper body can compress the abdominal contents and restrict the downward movement of the diaphragm.

This compression can limit the diaphragm's ability to contract fully, leading to shallower and more restricted breathing. As a result, the lungs may not receive as much fresh air, and the overall efficiency of breathing may be diminished. Additionally, slouching can also contribute to muscle imbalances and tension in the chest and back, which can further impact breathing mechanics.

Maintaining a proper sitting posture with an upright spine allows the diaphragm to function optimally by providing enough space for its downward movement during inhalation. This promotes deeper and more efficient breathing, facilitating adequate oxygen intake and overall respiratory well-being.


Q(Eam Taekyoung) : Does sitting in a slouched position restrict both thoracic and abdominal breathing?

A(ChatGPT) : Sitting in a slouched position can indeed restrict both thoracic and abdominal breathing to some extent. Here's a breakdown of how each type of breathing may be affected:

Thoracic breathing: Thoracic breathing primarily involves the expansion and contraction of the ribcage. When you inhale, the intercostal muscles between the ribs help lift and expand the ribcage, allowing the lungs to fill with air. In a slouched position, the forward bending of the upper body can compress the ribcage, limiting its ability to expand fully. This restriction can impede the natural upward and outward movement of the ribcage during inhalation, leading to shallower thoracic breathing.

Abdominal breathing: Abdominal breathing, also known as diaphragmatic breathing or belly breathing, involves the downward movement of the diaphragm muscle. During inhalation, the diaphragm contracts and moves downward, pushing the abdominal organs downward and causing the abdomen to expand. This allows the lungs to fill with air more effectively. In a slouched position, the compression of the abdominal region due to the forward bending can restrict the diaphragm's downward movement, thereby limiting the extent of abdominal breathing.

By slouching, you might inadvertently engage more shallow and inefficient breathing patterns, relying more on accessory muscles in the neck and shoulders rather than the diaphragm. This can result in reduced oxygen intake, increased muscle tension, and potential respiratory discomfort.

To promote optimal breathing, it's generally recommended to maintain an upright posture that allows for unrestricted movement of both the ribcage and the diaphragm. This facilitates a more balanced combination of thoracic and abdominal breathing, supporting efficient respiration and overall well-being.


Q(Eam Taekyoung) : Is there any research on whether it's better to look straight ahead or slightly upward when sitting? 

A(ChatGPT) : Research on the specific angle of gaze while sitting is relatively limited, but there are some general guidelines and considerations regarding the alignment of the head and neck in relation to the spine. Here's what we know:

Neutral head position: Maintaining a neutral head position, where the head is aligned with the spine, is generally recommended to minimize strain on the neck and promote good posture. This means that neither excessive upward nor downward tilting of the head is ideal.

Eye level and ergonomic setup: When sitting at a desk or using electronic devices, it is often advised to position the screen or work surface at eye level. This helps prevent excessive neck flexion or extension and promotes a more comfortable and natural head posture.

Individual comfort: The most suitable gaze angle can vary from person to person based on their specific postural habits, visual needs, and any existing musculoskeletal conditions. Some individuals may find slight upward gaze angles more comfortable, while others may prefer looking straight ahead.

Ergonomic adjustments: It's important to consider the overall ergonomics of your sitting setup. Ensure that your chair, desk, and screen height are appropriately adjusted to support a neutral head and neck position. Making these adjustments can have a more significant impact on overall comfort and posture than the precise angle of gaze alone.

While specific research on the angle of gaze during sitting is limited, maintaining a neutral head position and optimizing ergonomic factors are generally recommended. It's also important to listen to your body and adjust your posture based on individual comfort and any signs of discomfort or strain. If you have specific concerns or chronic pain, consulting with a healthcare professional or ergonomics specialist can provide personalized guidance for your situation.


Q(Eam Taekyoung) : Can you give me the title and author of a paper that relates to what you said above?

A(ChatGPT) : I apologize for the confusion, but as an AI language model, I don't have real-time access to a database of published papers. I can provide general information based on my pre-existing knowledge, which includes information up until September 2021. Therefore, I can't provide you with a specific paper title or author related to the precise angle of gaze while sitting.

If you're interested in exploring scientific literature on ergonomics, posture, or the impact of head position while sitting, I recommend searching academic databases such as PubMed, Google Scholar, or other reputable research platforms. You can use keywords such as "head posture while sitting," "ergonomics of gaze angle," or related terms to find relevant studies and articles published by experts in the field.

Bipedalism, not a revolution, but a revolution

Regarding when the first bipedalism occurred, there are claims of about 7 million years ago, about 5-6 million years ago, and about 3.6 million years ago.


The University of Munich paper below challenges the notion that the function of the second bounce in the human foot is not clear, and that it is unusual to have a 90-degree angle between the foot and leg. 

Phys. Rev. E 106, 064405 (2022) - Foot function enabled by human walking dynamics (aps.org)

The answer to this problem is that "the foot tries to remain stationary for as long as possible to maintain balance, but the ankle uses that downtime to slowly build up energy for its final release, and then the second bounce of the stride, when the knee bends just before the foot drops, provides the final push needed to throw the ankle into the next step. 


This is a great engineering interpretation. However, as a whole, it seems to lack insight. The functions of the front and hind feet of a quadruped have been consolidated into two feet during the evolution of uprightness. The functions of the animal's four legs were consolidated into two feet. 

In time, this evolution from quadrupeds to fully upright humans is the result of many small evolutions over a very long period of time. But if you compare the beginning and end of this evolution, it's pretty revolutionary. The balancing functions of the tetrapods' tails were largely transferred to our two arms, the jumping/landing/shock-absorbing functions of the quadrupeds were transferred entirely to our two feet, the attack functions of our forepaws and teeth were transferred to our hands, and the mouth, which was responsible for eating and attacking, was virtually reduced to eating. 


The key reason for this rearrangement of functions, however, is that the evolutionary journey toward full uprightness required less and less force to support the moment generated by the forward protruding head and, conversely, more and more surplus energy. Surplus energy provided the capacity to think. It is the source from which fire, tools, writing, and language became available. It happened too long in time to be called a revolution, but in content it certainly seems to be the greatest of all revolutions.

Our bodies are designed like a reciprocating engine!

 Our bodies are designed like a reciprocating engine!

In the human body, some organs are bilaterally symmetrical, while others are just one. Why is our body designed this way?

* Symmetrical body parts: arms, legs, muscles, vascular system, nervous system, lymphatic system, brain, ears, eyes, nose, lungs, and kidneys.

* Single organs: heart, digestive system, liver, reproductive system

Our bodies evolved to be optimized for running, and modern humans still have them. When we run, when our left foot is on the ground, the organs on the left side of the body are in a strong state of rigidity (tension) and the right side is in a strong state of relaxation. When the right foot lands, the right side of the body is in a state of strong tension and the left side is in a state of strong relaxation. This cycle continues while running. The same mechanism works when we walk, but the degree of tension and relaxation is weaker.

It's like a reciprocating engine, which performs a repetitive cycle of intake, compression, detonation, and exhaust.

A conversation with Hannah Arendt about evil

Q(Eam Taekyoung) : Can you tell me about Hannah Arendt ?

A(ChatGPT) : Hannah Arendt (1906-1975) was a German-born American philosopher and political theorist known for her influential writings on topics such as totalitarianism, democracy, and the nature of evil. She was one of the most important thinkers of the 20th century and her work continues to be studied and debated today.

Arendt was born in Hanover, Germany, and studied philosophy with the philosopher Martin Heidegger, with whom she had a romantic relationship. She later broke with Heidegger due to his association with the Nazi party.

During World War II, Arendt fled Germany and eventually settled in the United States. She became a citizen in 1951 and taught at several universities, including the University of Chicago and the New School for Social Research in New York City.

One of Arendt's most famous works is "The Origins of Totalitarianism," published in 1951. In this book, she analyzes the rise of totalitarianism in Europe and argues that it is rooted in the breakdown of traditional forms of authority and the alienation of individuals from society.

Arendt also wrote extensively on the nature of evil, arguing that evil is not an inherent characteristic of individuals but rather a result of their actions and the social and political context in which those actions occur. She famously covered the trial of Nazi war criminal Adolf Eichmann in Jerusalem in 1961 and coined the phrase "the banality of evil" to describe the way in which Eichmann and other Nazis seemed to act without any real awareness of the harm they were causing.

Other important works by Arendt include "The Human Condition" (1958), in which she explores the relationship between humanity and the world, and "On Revolution" (1963), which analyzes the French and American revolutions and the role of violence in political change.

Overall, Arendt's work has had a significant impact on political and philosophical thought, and her ideas continue to be studied and debated today.



Q(Eam Taekyoung) : Please tell me more about "In this book, she analyzes the rise of totalitarianism in Europe and argues that it is rooted in the breakdown of traditional forms of authority and the alienation of individuals from society." above.

A(ChatGPT) : Sure, I'd be happy to provide more information on this topic.

In "The Origins of Totalitarianism," Hannah Arendt examines the political, social, and economic factors that led to the rise of totalitarianism in Europe during the 20th century. She argues that totalitarianism is not simply a form of authoritarianism but is instead a fundamentally different type of regime that seeks to completely control every aspect of individual and collective life.

Arendt argues that the origins of totalitarianism can be traced back to the breakdown of traditional forms of authority, such as monarchies and aristocracies, in the wake of World War I. The collapse of these structures created a sense of chaos and uncertainty, which allowed new forms of political extremism to emerge.

Arendt also emphasizes the importance of the alienation of individuals from society in the rise of totalitarianism. She argues that the modern world has created a sense of rootlessness and isolation, with individuals feeling disconnected from their communities and lacking a sense of purpose or belonging. This alienation can create a desire for a sense of belonging and a willingness to submit to a powerful authority figure, which can make people more susceptible to totalitarianism.

Furthermore, Arendt argues that totalitarian regimes seek to create a new kind of society, one that is based on the complete subordination of the individual to the state. This involves the destruction of all forms of civil society, such as trade unions, political parties, and other organizations that could challenge the state's power. Instead, the state becomes the sole source of authority and control, and every aspect of life is subject to its dictates.

Overall, Arendt's analysis of the rise of totalitarianism in Europe provides a comprehensive and nuanced perspective on this complex historical phenomenon. Her work continues to be studied and debated today as scholars seek to understand the causes and consequences of totalitarianism and its relevance to contemporary political and social issues.



Q(Eam Taekyoung) : Please tell me more about "evil is not an inherent characteristic of individuals but rather a result of their actions and the social and political context in which those actions occur." above.

A(ChatGPT) : Certainly, I'd be happy to provide more information on this topic.

In Hannah Arendt's writings on the nature of evil, she challenges the idea that evil is an inherent characteristic of individuals. Instead, she argues that evil is the result of a combination of individual actions and the social and political context in which those actions occur.

Arendt rejects the notion that evil is simply the result of an individual's personal traits, such as a lack of empathy or a desire for power. Instead, she contends that people can engage in evil acts even if they are not inherently "evil" themselves. For example, in her coverage of the trial of Adolf Eichmann, she argued that Eichmann was not a monster, but rather a "desk murderer" who participated in the Holocaust due to his role in the bureaucratic machinery of the Nazi regime.

Arendt also emphasizes the importance of the social and political context in which evil acts occur. She argues that in certain circumstances, social and political structures can create conditions that make it easier for individuals to engage in evil behavior. For example, she argues that the totalitarian regimes of Nazi Germany and Soviet Russia created an environment that facilitated the perpetration of mass atrocities, by removing the restraints of civil society and replacing them with an all-encompassing state control.

Overall, Arendt's ideas challenge simplistic notions of good and evil and highlight the complex interplay between individual actions and social and political structures. Her work has had a significant impact on philosophy and political theory, and continues to be studied and debated today.



Q(Eam Taekyoung) : I am defining evil as follows 

"Evil is the intention and act of pushing a balance state towards bias concentration. There are three types of balance: current balance, temporal (past, present, and future) balance, and spatial balance. Temporal balance can also be evil if it interferes with temporal or spatial balance. "

Pretend you are Hannah Arendt and critique my definition of evil.

A(ChatGPT) : As an AI language model, I cannot pretend to be someone else, but I can provide some insights into your definition of evil based on Hannah Arendt's ideas.

Arendt's understanding of evil is somewhat different from your definition, as she does not focus on the idea of "balance" but rather on the idea of action and its consequences within a political and social context. Arendt argued that evil is not an inherent quality of individuals but is rather a result of their actions, which can have devastating consequences for others. She also believed that evil acts are often facilitated by political and social structures that allow individuals to act with impunity.

Your definition of evil seems to suggest that any action that upsets a balance is inherently evil. However, this definition is somewhat vague and does not provide a clear moral framework for determining what constitutes evil. For example, would a doctor who administers a life-saving treatment that temporarily upsets a patient's physiological balance be considered evil? Would a political activist who protests against an unjust law that upsets the status quo be considered evil?

Furthermore, your definition of evil does not account for the complexity and nuance of the human experience. Arendt argued that human actions are shaped by a wide range of factors, including social, cultural, and historical contexts, and that understanding the motivations behind these actions is crucial for understanding the nature of evil.

In summary, while your definition of evil highlights the importance of balance, it may be too broad and does not provide a clear moral framework for determining what constitutes evil. Arendt's understanding of evil emphasizes the importance of context and the consequences of human action within a political and social framework.



Q(Eam Taekyoung) : My definition of evil is derived from the perspective of encompassing evil done by social organisms such as social groups, companies, and nations, not just humans. For example, the rapid progression from agrarian, industrial, and then digital societies has socialised people to sedentary activities, and this has served to intensify various degenerative diseases, depression, and aggression in modern people whose bodies have evolved to run. The lack of a comprehensive concept of evil seems to increase the likelihood of social misdirection.   

A(ChatGPT) : Thank you for providing additional context to your definition of evil. Your definition seems to focus on the broader societal impact of actions and their effects on balance, rather than solely on individual actions.

While Hannah Arendt did not specifically address the concept of evil as it applies to social organisms like groups, companies, and nations, her work does emphasize the importance of understanding the broader societal context in which actions occur. Arendt argued that political and social structures can create conditions that facilitate evil acts, and that understanding the motivations behind these actions is crucial for understanding the nature of evil.

However, your definition still raises some questions about how to determine what constitutes an imbalance that is evil. For example, it may be difficult to determine when a particular societal change or development crosses the line into causing an imbalance that is harmful or evil.

Overall, it is important to have a comprehensive concept of evil to guide ethical decision-making and social direction. However, it is also important to recognize that concepts of evil may differ based on cultural, social, and historical context, and that understanding these contexts is crucial for developing a nuanced understanding of the nature of evil.



Q(Eam Taekyoung) : While laws can only be adapted to changing circumstances, I feel that a definition of evil needs to be a proactive comprehensive norm to overcome this limitation of the law. Therefore, I have included the following in the definition of evil above: "There are three kinds of balance: temporal balance, temporal (past, present, and future) balance, and spatial balance. Temporal balance can also be evil if it interferes with temporal or spatial balance. "

A(ChatGPT) : Your revised definition still places emphasis on balance and the potential for actions to upset that balance. However, it still raises questions about how to determine when an action that upsets balance becomes evil.

While it is important to have a comprehensive normative framework for understanding and preventing evil, it can be challenging to develop such a framework that is applicable across different social and cultural contexts. Furthermore, definitions of evil can evolve over time, as societal values and norms shift.

Hannah Arendt's work emphasizes the importance of understanding the historical, social, and political context in which actions occur, as well as the motivations behind those actions. This approach recognizes that the nature of evil is complex and multifaceted, and cannot be reduced to a simple definition based solely on the concept of balance.

In summary, while your definition of evil emphasizes the importance of balance and its potential disruption, it may still be challenging to apply this concept in a comprehensive and consistent manner across different social and cultural contexts.



Q(Eam Taekyoung) : Great discussion, thank you!

A(ChatGPT) : I'm glad I was able to help! If you have any other questions, feel free to ask. Thank you!

Precise understanding of Frozen shoulder and Rotator cuff injuries(by Mayo Clinic and by Postural Expert)

A precise understanding of the causes of frozen shoulder and rotator cuff injuries, Eam Taekyoung/Postural expert

Mayo Clinic believes that 'frozen shoulder' occurs when the joint capsule thickens and tightens around the shoulder joint, restricting the movement of the shoulder joint. It's believed that it can occur when the shoulder is immobilised for a long period of time, especially after surgery or an arm fracture. However, it's not clear why this happens in some people.

It is also believed that most rotator cuff injuries are caused by gradual wear and tear of the tendon tissue, which can be irritated or damaged by repetitive overhead activities or prolonged heavy lifting. As a posture expert, I don't think the above causal analysis is wrong, but I think it is not sufficient.



Sedentary socialisation During the Paleolithic era, humans lived a hunter-gatherer lifestyle, so the ability to run was paramount to survival, and our bodies were optimised for running. However, the fact that the centre of gravity of the head is tilted at about 12 degrees when looking forward, and the average marathon runner's spine is also tilted at about 12 degrees, suggests that modern humans still have a Paleolithic running body. However, as we have progressed through agricultural and industrial societies, we have spent an increasing amount of time sitting in a hunched posture rather than running. More recently, rapid digital socialisation, typified by the use of smartphones, has accelerated this trend. When walking or running, steps per minute and heart rate (cadence) are almost the same. In a marathon, the average steps per minute and heart rate per minute are both around 150. Both of these values get smaller and smaller as your speed decreases. This means that your cardiovascular system is beating at roughly the same frequency as the number of repetitions of the load on your legs. This, in turn, means that the left and right muscles and the cardiovascular system are optimised to tense and relax in equal cycles. Therefore, the healthier an individual is, the more likely he is to have a complete cycle of tension and relaxation in his left and right lumbar muscles, which is the same cycle as his steps. This means that the longer an individual remains in a posture, such as sitting in a slouched posture with both the left and right lumbar muscles tense, the more his muscles and cardiovascular system will deteriorate.



Characteristics of people around 50 years old 

Frozen shoulder tends to occur around the age of 50. Rotator cuff injuries also occur mostly in middle-aged people, with the exception of those caused by overexertion. In general, we reach our maximum muscle mass in our 30s and then it gradually decreases. From your 50s onwards, you"ll lose 1 to 2 per cent of your muscle each year, and by your 70s, you"ll have lost almost half of it. Maintaining as much muscle mass as possible in your 30s can help you avoid sarcopenia as you age. However, the rate of muscle loss can vary greatly between individuals, depending on factors such as genetics, lifestyle, and overall health. Muscles work in conjunction with ligaments and tendons to connect bits of bone that don't hold together on their own and maintain the shape of the body. If you were to remove all of the "muscles, ligaments, and tendons" at once, your body would collapse like a deflated balloon. As muscle mass decreases, the strength to support the body's bones decreases, and as the strength to support the bones decreases, the body becomes more slumped and deformed, and as the body becomes more slumped and deformed, the blood vessels and nerves that are naturally responsible for the body's logistics are unable to maintain their normal shape and condition, which can lead to a sharp increase in various diseases. At the age of about 50, the decline in muscle mass that started at about 30 has been going on for about 15 years. This is a time when a steady decline in the amount of physical activity and range of motion of the body's muscles is quite advanced.

The effects of slouched posture For people who do a lot of running in their daily routine, the zigzag movement of the legs and shoulders remains the same contributing factor when walking. However, for people whose main activity is sitting, the head is often in a downward gaze, which causes the head to gradually protrude forward at an imperceptible rate. However, as this head protrusion increases, the zigzag movement of the shoulders becomes less and less necessary. The protruded head provides the partial forward movement force that the shoulder was responsible for, so the shoulder doesn't need to be involved. The decreased zigzag movement of the shoulder atrophies the repetitive activity of contraction and relaxation of the muscles associated with the shoulder, thoracic and lumbar spine, and eventually leads to a state of constant contraction of the associated muscles. As the forward projection of the head increases, the strides become smaller and smaller and more frequent shuffling. In order to prevent the body from collapsing under the excessive moment generated by the head, the soles of the feet move forward quickly to prevent collapse. Many elderly people who are severely stooped often walk with a hobble.


In the context of the frozen shoulder, the shoulder joint capsule is a 360-degree joint. The joint capsule at the base of the joint is loose, which means that it stretches smoothly when the muscles contract to move the arm forward or sideways. When the capsule at the base of the joint becomes contractile and stiff, it causes pain when you move your shoulder.

Slouched posture also reduces the use and range of motion of the Scalene muscles, intercostal muscles, and pectoralis manor, which have the ability to lift the ribs and expand the chest space. However, it constantly strains the trapezius and rotator cuff muscles and reduces their range of motion. The rotator cuff unites four muscles: supraspinatus, infraspinatus, deltoid, and subscapularis.






Better understand the causes of frozen shoulder and rotator cuff injuries Let"s summarise what we"ve seen above. 👉 Sedentary socialisation increases the amount of time we spend in a slouched posture. 👉 Sitting in a slouched posture keeps both the left and right muscles of the lumbar spine in a state of tension, which reduces muscle and cardiovascular function. 👉 The age of about 50 years marks about 15 years of progression in the loss of muscle mass that began at about 30 years of age, and a steady decline in the amount of physical activity and range of motion of the body's muscles. 👉 As the forward projection of the head increases, the shoulder has less and less of a 'forward mobilising function' to perform, and therefore less and less of a zigzagging motion of the shoulder to cause a 'forward mobilising function'. This reduction can lead to atrophy of the repetitive activity of contraction and relaxation of the muscles associated with the shoulder, thoracic and lumbar spine, and eventually to persistent contractures of the associated muscles. 👉 Slouched posture reduces the use and range of motion of the Scalene muscles, intercostal muscles, and pectoralis manor. However, it continuously strains the trapezius and rotator cuff muscles and reduces their range of motion.

These are the underlying mechanisms by which frozen shoulder and rotator cuff injuries (other than those caused by overexertion) occur in middle-aged and older people.
