When you are young, you can't do anything harmful to your health, because you are hard enough and have good physical quality, so even if you sleep for a few days, you will find that it is like a car halfway up the mountain, and the braking speed can't stop. Physical fitness is getting worse every day. If you can't have a good figure, you may not care too much all your life. Men after the age of 40 must pay attention to maintaining their health. Soaking Lycium barbarum in a thermos cup is a routine operation. Other square dances such as Tai Chi Chuan are good for you.
Pay attention to diet and daily life, which are all factors related to the quality of life in the second half of life, not to mention quitting smoking and drinking, and don't go to those alcoholic liquor stores.
Divorce cannot be done. A man's family after 40 must be stable. Don't divorce easily. Marriage stability is very important. This is not just a love belonging. In fact, marriage is the guarantee for the rest of his life. If a man will divorce after 40, you will put yourself in a very embarrassing position unless you have particularly good conditions. Can you guarantee that the daughter-in-law you are looking for will get along with you? Can you guarantee that your children will be well integrated into the new family? All these will add unnecessary trouble in the future.
To sum up, a 40-year-old man must do two things well, the first is to maintain his health, and the second is to manage his marriage well.
