　　When it comes to health and disease, most of people can’t escape it. To begin with, some people often run fever and catch heavy cold; in addition, serious diseases like cancer and tumor cause a lot of deaths; last but not the least, diseases like aids and Sars spreading quickly among people can’t be ignored.

　　The causes of the disease may be concluded as follows: on one hand, it certainly has something to do with people’s life style and living habits such as spitting in public, littering everywhere, eating with dirty hands etc. On another hand, people are too lazy to go in for all kinds of sports, gradually they have a poor health with years passing by.

　　From what has been discussed above, we may safely draw a conclusion that to stay away from disease, first of all we should get rid of bad habits; at the same time, doing exercise is an effective way to prevent disease.
