　　One possible version

　　It is generally believed that different people have different habits. Some people are addicted to habits like drinking and smoking, while others pay special attention to healthy diet and never taste things like alcohol and cigarettes.

　　It goes without saying that there is close relationship between personal habits and public health. On the one hand, good habits serve as the necessary basis of public health, that is to say, without good habits, public health can’t be guaranteed. On the other hand, infectious disease is the natural result brought by dirty habits, like AIDS, SARS, H1N1 flu and so on.

　　Personally, I think it is high time we placed emphasis on improving personal habits and public health. If we mind our manners and behave ourselves well, there must be a bright and encouraging future.
