We are very tired every day because we have so much homework to do. So it is very important for us to keep healthy. Then how can we keep healthy ? I think the best way is to take part in sports and have a good sleep .You should also eat more vegetables and fruit, but less meat, because they are good for your body .What's more, you must go to bed early and get up early ,too. If you can do it , I think you can keep healthy easily.
