You can take away our money， house， car， or even our clothes and we can survive¹． But if our health was taken away， we would surely² die． That is why we always try to eat in a healthy way and exercise regularly³．

In order to eat healthily， I usually avoid⁴ eating food high in fat， like French fries or cookies． I also eat little meat． I eat a lot of vegetables and fresh fruit which are full of vitamins⁵．

Taking exercise every day helps us build a strong body． Regular exercise is an important part of keeping me healthy．

What's more， I think friends are an important part of one's health． Many studies show that people with a wide range⁶ of social contacts⁷ get sick less than those who don't． I always feel better when I am with friends than when I am alone． When I am with my friends， I always laugh． Laughing is also an important part of health． I like to laugh with my friends．

By eating properly⁸ and exercising regularly， I can keep my body at a proper weight and keep healthy． By spending time with my friends， I can keep my mind as well as my body happy． These things sound easy to do， but not many people can manage them． I think a strong will is necessary if we want to keep healthy．
