It's very important to keep helthy because without good health,we'll do nothing at all. Besides, we will bring troublesome and burden to our family and the society. I think there are many ways to keep healthy. Firstly, doing exercise is one of the best way. We should go out do do sports and breathe the fresh air. Secondly, we should eat three healthy meals every day. We'd better eat enough vegetables and fuit because they are rich in vitamines which are good for our health. Thirdly, relax when we feel tired. We can listen to some light music.
