What did you do when you knew it was unhealthy?

I think everyone knows that it is unhealthy but still unhealthy. One thing that everyone, many people may be doing is staying up late. I won't say much about the dangers of staying up late here. It must be bad. If you often stay up late, it may lead to a series of diseases, low immune system, various diseases and so on. And staying up late for a long time may lead to sudden death. However, many people still stay up late because of work or their own problems. Students who can't do this because of work, but still stay up late because of their own reasons. Here, I suggest you improve yourself, remember to control yourself and try not to stay up late, because staying up late is really bad for the whole person. Be sure to get enough sleep. Try not to stay up late again.
