At the same time, exercise properly so that physical fitness will not decay too fast. Because of long-term labor, manual workers' physical fitness decays slowly, their muscles remain in good condition, but non-manual workers can't, and their strength and endurance are obviously reduced. At the age of 50, the vegetative function immediately declined. Motor function declines immediately at the age of 60. At the age of 70, the temperament function immediately declined. At the age of 80, the function of taste buds immediately declined. At the age of 90, people's sexual function immediately declines. 100 years old returns to infancy. At each stage, nothing has changed, which is not necessarily a good thing.

Although the overall decline before the age of 40 is a little, it is not obvious. For example, I can play a big 1 1 player game and stay up all night. Although it is not as good as when I was young, it is ok. Moreover, cognitive ability and judgment ability are much better than when they were young. Men don't have to worry about being forty. Even if their friends who are almost fifty are full of enthusiasm for life, they feel that they are in their thirties and their appearance is also in their thirties. Nothing has changed.

Although there was white hair before the age of 30, it was rare. If you pull them out, they will disappear. After the age of 30, I couldn't catch up with the growth rate, and finally I was too lazy to pull it out. In terms of quantity, a small piece began to turn white, probably related to too much pressure. I also thought about this question these two days. I think my figure should go downhill from the age of 35, and it will become more and more obvious at the age of 40. I have no impulse and enthusiasm when I was young. After staying up late, my body will slowly recover, my gastrointestinal sleep will be very different from before, and my physiological needs will tend to be peaceful.

Although I still insist on playing badminton and football every week, I feel that badminton skills have not reached the bottleneck, but have reached the ceiling and I can't get in anymore. There are fewer and fewer technical moves that football can do ... the degree of cunning on the court is getting stronger and stronger. When I was about 20 years old, I worked overtime in Guangdong until I got off work at night 10: 30. After work, my colleagues and I went skating at the skating rink. Now I am 35 years old, and I feel that my physical strength is not as good as before, especially my legs and feet.
