What is the most important thing in the world? I think it is health. You can take away our money, houses, cars, or even our clothes and we can still survive (生存). But if our health is taken away, we will be sure to lose our lives. That is why we always try to eat in healthy way and exercise regularly. Taking exercise every day is important for both the young and the old. It helps us build strong and healthy bodies. We should do sports for half an hour or forty minutes every morning or every evening, such as going for a walk, playing basketball or football, swimming…

To keep healthy, I have another idea: Don’t overwork. Too much work will be bad for you.
