I have an unhealthy lifestyle， so I am not healthy。 I never exercise。 I take a bus to school every morning。 My eating habits are very bad。 I eat too much meat and a few vegetables。 I eat fruit once or twice a week。 I like junk food very much。 I eat it twice a day。 I never drink milk。 I sleep seven hours every night。 So I think I am unhealthy。 Now， I know good health will help me get good grades。 So you see， I am looking after my health now。
