A healthy body is very important to each of us. If you are ill, you will feel pain all over and have no energy to work. The only thing you want to do is lie in bed. When you are healthy, you eat well, sleep well, sing happily, dance well, and do everything you like to enjoy life. The method of keeping healthy is changing. Get up early in the morning, go out, breathe fresh air and exercise. Running and swimming are very helpful to health. If you are a busy person and can't allocate time to do these things, here are some useful ways to stay healthy. The easiest way is to walk to work instead of riding a bike or taking a bus. You should also have a regular physical examination. Your doctor can clearly understand your physical condition, and he can give you useful advice to keep healthy. You should always try to make yourself happy. If you feel happy, you can eat well, sleep well, and your physical condition will be good.

Health is a person's most precious property besides life. My advice to those who want to have a happy life in this beautiful world is to try to keep healthy in various ways.
