Upright walking is an important distinction between humans and animals. In fact, the emergence of upright walking in apes was quite sudden in the seemingly long biological evolution, a leap of behavior brought about for some reason. This leap brought about the emergence of the human branch on Earth, but also led to a number of diseases that are specific to humans because certain organs were unable to keep up with this leap in upright walking. What diseases are associated with upright walking? According to Dr. Pan, cervical spondylosis, lumbar spondylosis, hemorrhoids, miscarriages, varicose veins in the lower extremities, osteoarthritis of the lower extremities, and even hip fractures can all be complications of walking upright. Prevention can be done in the opposite direction. Cervical spondylosis: If insufficient blood supply to the vertebrobasilar artery is attributed to cervical spondylosis, then the problem brought to the brain by walking upright is the problem of insufficient blood supply, and the problem brought to the cervical spine is the problem of cervical instability. Insufficient blood supply to the brain is due to both blood pressure and the vertebral artery. Cervical instability is due to the sudden upright 90-degree body position required from apes to humans, the evolution of the cervical spine can not keep up, but also because of the weight problem brought about by the development of the human brain (compared with monkeys, humans are like big-headed dolls), the increased mass of the human head means that when shaking the head inertia is very large, the neck muscles are not easy to control the shaking of the head if they do not react quickly enough and are not strong enough. For example, when suddenly braking sharply, the neck will appear ‘whipping’ like injury, the consequences are very serious – cervical spine dislocation or paraplegia. There is only one solution, strengthen the muscle strength training of the neck, try to make the head sway within the limits of the range. Look at Schumacher’s thick neck, you will understand why motorsports is not generally people can go to play life. The weak points of the human cervical spine are the mobility of the atlantoaxial vertebrae, the slenderness of the pivotal dentition, the blandness of the hook vertebral joints, the level of the upper and lower synapses, the degeneration of the collar ligaments, and the weakness of the muscles at the back of the neck. Hanging was designed to take advantage of these human characteristics. Many people believe that hanging is due to asphyxiation, but in fact it is largely due to atlantoaxial subluxation paraplegia. Why is the incidence of cervical spondylosis increasing more and more every year? Dr. Pan believes that the main reason is the accumulation of strain in the ever-increasing number of people studying and working with their heads down; cell phones and PDAs are probably the biggest culprits, but the most fundamental reason is the problem of the evolutionary lag of the cervical spine. Lumbar spondylosis: the lumbar spine was never ready to become the ‘top pillar’ of the upper part of the body, and has not evolved to be able to handle all the burdens that come with walking upright. The physiological curvature of the lumbar spine is not unique to humans, but is also found in the spine of mammals such as dogs and cats, but humans seem to have diverted it for other uses, becoming a shock absorber for the upper body, and the effect is quite good. The lumbar spine has similar problems to the cervical spine, in addition to the huge disc pressure and increased pressure in the inferior spinal canal, which are problems that basically do not exist in other animals. Therefore, human lumbar discs are prone to degeneration, lumbar disc herniation, ligamentum flavum hypertrophy, lumbar spinal stenosis, and spinal nerve compression syndrome. Upright walking also brings lumbosacral spondylolisthesis, arch rupture and other unique diseases, so it can be said that most of the existing human back pain problems are related to upright walking, but of course also with improper sitting and driving and other life factors. Hemorrhoids, pelvic stasis, varicose veins of the lower extremities, varicose veins of the spermatic cord, etc.: all these varicose vein related diseases occur below the heart, and it should be said that they are all caused by upright walking which elevates the heart, and the pathogenesis is very similar. The veins themselves have very low pressure, plus these veins have not evolved to produce a venous valve or a venous valve that can adapt to the sudden increase in blood pressure, so they produce dilated and inflated veins, slowing down the blood flow, like a balloon filled with water, and the walls of the vessels become thin, causing diseases such as bleeding hemorrhoids once they rupture. Why are gynecological diseases so common in humans? Pan’s doctors believe that, in addition to the decline in resistance, the increase in sexual activity, abortion and other reasons, the most important, I’m afraid, is the problem of pelvic organ venous stasis and lymphatic return obstruction brought about by walking upright. Spontaneous abortion: we all feel that infertility is now on the increase, pregnant women are more vulnerable, fertility is far inferior to four-legged mammals, a little carelessness will be spontaneous abortion. In addition to the decline in the quantity and quality of men’s sperm and the increase in inflammation of the female reproductive system, Dr. Pan believes that there is an important reason for this, and that is the downward opening of the cervix brought on by walking upright. With a downward cervical opening**, there is a risk of loss of fertilized eggs or fetuses due to gravity, so women who are infertile or have habitual abortions should avoid standing as much as possible and should instead maintain a more head-bottom-hip-high position. Lower extremity osteoarthritis degeneration: Human lower extremity osteoarthritis degeneration is much more severe than upper extremity, which is not unrelated to upright walking. When the human upper limbs are independent to engage in labor, the entire weight is borne by the lower limbs. However, as we have said, standing and walking are very sudden leaps in history, and the structure of the human lower limbs has not evolved in time, so the bone joints cannot withstand this work and often fail in advance. In the case of the knee joint, the human knee joint and the dog’s knee joint structure is not much different, but the human knee joint often needs to bear more labor intensity, if the body is obese that the situation will be worse, will appear early joint cartilage wear, meniscus chronic damage, knee osteophytes and other joint degeneration disease. Therefore, Pan’s doctors promote lean life and encourage obese people to reduce weight. The old saying that it is hard to buy money to be thin in old age is of great health value.
