Life lies in exercise, which has many benefits for the body. Exercise can effectively promote the body's blood circulation, increase self-immunity, increase muscle mass and make the body more energetic. There is also a saying that the most important thing for a healthy body is sufficient yang. The more the yang is, the better the human body is, but all human activities and sports consume the yang. Exercise consumes more yang than normal physiological activities, so exercise is not conducive to longevity.

So people began to say that health needs to be quiet. This statement actually comes from people's observation of turtles, because turtles are often considered as representatives of longevity. They move slowly and have little time for activities. Reducing energy consumption is beneficial to the longevity of their organs. For example, many animals choose to hibernate in winter. Hibernation is basically in a static state, and the metabolism will be slower, so the turtle's life will be longer.
