1. In the evolution form of natural death mechanics, the concise explanation is: under the condition of unintentional control, the spine movement is difficult to strengthen, and the reverse movement of the longitudinal and transverse diaphragms disappears, that is, death. From the evolutionary point of view, this set of human body techniques, including movements, is the basic method for the cerebral cortex to break through the automatic breathing function of the medulla oblongata and hinder the conscious control of deep muscles.

2. Human body technology is an important form for human brain to use human body. After it is developed, it will be used by human beings forever like arm and leg movements, and will not change much. Spinal movement is the most difficult core part to master. Once mastered, the application is simpler and more effective.

3. It is the deep muscles of the arms and legs in the skull, chest, abdomen and spine that sustain their lives in the human body system. Spinal force system plays a leading role in deep muscles. This force system involves heart muscle, smooth muscle and skeletal muscle. Although there is only skeletal muscle movement, it involves three muscles. As long as the method is proper, it has a straightforward fitness function in the process of mastering.

After 4.40 years old, the variation of human physical system is obvious, so it is necessary for middle-aged and elderly people to exercise. Spinal movements are few and precise, so it is easy to use at any time after practice. Very suitable for middle-aged and elderly people.

This method is still in the experimental stage, so don't try it easily without the dedication of being the first and being good at exploring (especially without guidance).
