In the world nothing is more important than health. If people took away our money, houses, cars, or even our clothes, we could still survive.    Then how can we keep healthy?
First of all, we should eat healthily. I usually avoid eating food high in fat, like French fries or cookies, which are junk food.     I only eat little meat.   It helps us build a strong body. Regular exercise is an important part of keeping me healthy. In addition, I think friends are an important part of one’s health.    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. It is good to stay with my friends.
By eating properly 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.
