First of all, we must understand what heredity is all about. It is the similarity between parents and offspring, which shows that traits can be passed from parents to offspring. It can be seen that heredity is related to DNA. And DNA can hardly be changed-it can only be said that it is almost the same, and now there is DNA editing technology. This is why children can still be found and identified decades after being trafficked.
At present, the doctor's definition of humpback is (encyclopedia): kyphosis is a common spinal deformation, which is a morphological change caused by thoracic kyphosis. It is more common in senile spinal deformity, improper sitting posture or rickets, ankylosing spondylitis and other diseases. Humpback can be corrected, which is called active humpback. Can not be corrected, called fixed humpback. Note: The author has reservations about whether humpback can be divided into movable type and fixed type. If there is, the humpback referred to in this paper also refers to the former, and includes the forward deformation of the cervical vertebra-I believe that all humpbacks can be corrected except those caused by strong external impact.
Hump is not hereditary, so many friends ask why newborn children don't hump (except deformity), but they often hump when they grow up. The reason why we are given the illusion of hunchback inheritance is that children are generally a bit like their parents. At the same time, when we see their parents' work habits and sports, we will imitate them from an early age, so they are all similar in these aspects, which gives us a feeling that hunchback is also hereditary. But humpback is not hereditary. Careful observation shows that there are several brothers and sisters. In many cases, only one or two of them will have hunchback problems and have no cousins. On the other hand, you can imagine that if a child is allowed to use a flat mattress (as shown below) that has appeared in recent years since birth, and keeps him lying on his back like that, then he will certainly grow into a posture of leaning back all the time (reminder: children must not overcorrect when using a flat mattress).
? In the author's opinion, the simplest way to explain that humpback is not hereditary is that ordinary humpback people can straighten their bodies, but they can't keep such a posture of holding their heads high for a long time because of habit problems. If you can keep this posture for a long time, you can naturally correct your hunchback. You can't change most genetic things.
Another phenomenon that can prove that humpback is not hereditary is that many people have corrected humpback. A famous case in China is that the inventor of the headrest mattress began to correct it at the age of 40, and it was basically corrected in less than two years. In the past two years, an 85-year-old grandmother corrected her hunchback with the help of a yoga instructor. As shown in the figure below:
? At present, in addition to surgery, other methods, such as yoga, fitness, standing posture, tilting mattress, etc., are all reverse correction methods, that is, do more chin-level or backward movements to keep your spine in a natural and straight posture. So as to achieve the purpose of correcting hunchback. You need to choose the right method that suits you. I suggest you consider tilting the mattress more. It is a new method in recent years, and it is also a better way to stick to it.
The author also knows that the above can only prove that humpback is not hereditary, and experts who know DNA are needed to prove that humpback is not hereditary, but at least from the above description, it can be seen that humpback can be corrected regardless of heredity, which is not difficult for modern people. We should not acquiesce that it is hereditary instead of changing it. The purpose of this paper is to transmit such a positive energy. You are also welcome to express your views.
