About how to keep healthy, I’d like to offer my advices. As we know, we teenagers are going through a rapid growth which needs to be support by a healthy and balanced diet. Thus, we need a variety of food but cut out the food rich in sugar or fat. However, we should take physical exercise regular. For example, we can play basketball or take walk after school. Have enough sleep is of great importance. Therefore, you should have at least eight hours of sleep every day and not stayed up too late. Only in this way that can we keep fit.
