Many old friends said, "Do you think exercise is useful? I think people who exercise all day may not live long. The one who doesn't exercise all day may not live long. Professor Zhao is 90 years old, and his trick is: never exercise. "

Generally speaking, exercise is definitely good for your health. Chinese medicine says: movement leads to yang, while quietness leads to yin. But there is a limit to everything. Motion and stillness vary from person to person. Some people are full of yang and active. If you keep them indoors all day, they will suffocate, and vice versa.

But there are three points to emphasize here: first, it is not good to be too dynamic and too quiet; Second, it is not advisable to sweat too much during exercise, and pay attention to sweating; Third, for the elderly, static is more important than dynamic; Many elderly people mistakenly believe that strenuous exercise is the best exercise as long as they run and jump hard in morning exercises. Obviously wrong.
