Nowadays, sports is not a career for young people. According to industry sources, although the average age of athletes in Tokyo Olympic Games is only about 25 years old, there are still many women in their forties. And with the continuous progress of science and technology and the efforts of all athletes, the career of athletes will be more and more lasting.

There is also a comparison between exercise and life expectancy. It is found that the exercise time is less than half an hour every day, but it can be carried out for more than half an hour to an hour every day. The probability of living to the age of 90 will increase by 1/5, and the average life expectancy of people who exercise longer will be higher. Other documents point out that people's life span can be gradually improved through moderate exercise in exploring fitness exercise and preventing life span. For example, people with poor physical fitness can strengthen their physical fitness by exercising every day.

"Athletes are overtrained, and their organs wear out at a young age, so middle-aged and elderly people are injured and their life expectancy is lower than that of ordinary people", which sounds reasonable. Our media often like to report the bleak news of some athletes after retirement. First of all, we must make it clear that we can't use special cases to discuss scientific problems, but we should look at universal laws and large-scale data. It is a crime to make rumors like this and use a few special cases as arguments.

Whether it is smoking and drinking until the age of 70 or 80, or the sudden death of athletes in their twenties in the competition, this special case can be found on the Internet today with developed information, but it still proves nothing. Almost many people think that the life span of athletes is shorter than that of ordinary people. The inherent impression is that they often train hard every day and break through the potential of their bodies, so their life expectancy is short. Wrong, this concept is going to change.
