Im very healthy because I have some very good habits. I think， to keep a healthy diet is the first important thing. So I often eat more vegetables， fruit， beans and some other green food. Secondly， I often take some exercise， such as table tennis， swimming， playing basketball and so on， so that I wont catch cold or some other illness easily. Also it is necessary to have enough sleep and have a good mood. I often sleep for 9 hours. I dont sleep too late and get up so late. If you want to have a healthy life， you should eat healthy food， take exercise and have enough sleep.
