First, when people are young, their energy and physical strength are very strong, and they seem to have inexhaustible energy. Tired again during the day, wake up as before; Staying up late is also a common practice, and sleeping for two hours can be full of energy. While lamenting how good it was when I was young, I also left myself with physical hidden dangers because of excessive profligacy. For example, cervical spondylosis caused by lack of exercise, three highs; Sub-health and hypertension caused by lack of sleep.
Second, the annual physical examination report is an early warning to the body; Cervical spondylosis makes you dizzy and uncomfortable. At that time, my family advised me that exercise was the best medicine. So, I began to take exercise as the last resort. At that time, I heard that swimming is one of the best fitness activities, which is very effective for strengthening the body, strengthening muscles and exercising bones and muscles. So, I got a swimming card. At first I didn't know how to swim, so I just flopped about in the shallow pool. And one day, a child who was only 4 or 5 years old swam over. I smiled, looked at me stupidly and said to me, "Uncle, your posture is wrong. Breaststroke should be like this. " So he kept demonstrating and asked me to do it. I was surprised and blushed, so I started practicing according to his instructions. The child is very serious and has demonstrated it many times. I am deeply touched by this incident. I must learn the spirit of helping children. Finally, I practiced day after day and finally got the deep water certificate. Swimming lasted nearly 10 years.
Thirdly, for various reasons, I changed to run for five years. My body obviously feels much better, and many unqualified indicators are normal during the physical examination.
