Chinese medicine does have this statement, but it is also an exaggeration. It is not that stretching can prolong life, even if it is accurate to one inch, it will not last for ten years. Moreover, the vein mentioned in Chinese medicine does not refer to our tendons or ligaments. Our life span is not controlled by bones, muscles, tendons or ligaments. It is closely related to our genetic factors and daily habits.
In ancient times, people who exercised regularly tended to be softer and lived longer, which is why people think that people with long tendons live longer. Therefore, in order to prolong life, it is useless to relax tendons and activate collaterals, but to adjust diet structure, improve living habits, quit smoking and drinking, and exercise properly, so as to help us have a healthy body.
In short, lacing can not prolong life, and the length of tendons is not a sign of longevity. Longevity is determined by both internal and external factors. If you want to have a healthy and long life, you should achieve it through healthy and regular eating habits. Some so-called stretching methods that can make you live longer can be learned as exercise according to your own situation, but be careful not to overstretch the tendons forcibly, which will damage your body.
