As we all know, we teenagers grow very fast, so we need plenty of nutritious foods, such as fish, meat, and beans, especially fresh vegetables and fruits. We had better not eat too much sweet. Also, we should take physical exercise regularly instead of studying in the classroom all the time. For example, you can play basketball or swim after school. What's more, having enough sleep is very important. So I advise you to have at least eight hours of sleep every day and not to stay up too late. And we shouldn't smoke and drink. Most importantly , we must have a good mentality. Only in this way can you keep fit.
