God, I'm 20 years old, and I'm at my best in all aspects. As long as there are no bad habits, what kind of health care do you need to eat normally and sleep normally? Your body will adjust itself. Don't think too weak about your body. Raising too much is not good for your health. No wonder people's immune system is getting worse and worse now.

Better looking, skin color, adequate sleep, reasonable diet, good skin at the age of 20, and good regeneration function. If you have a good figure, you can keep a symmetrical figure by keeping moderate exercise every week.
