People are beginning to attach much more importance to their health these days than ever before. They begin to realize that good healthis the most valuable possession a person can have. However, many people don't know how to stay healthy although great efforts have been made in this regard. In my opinion, there are three things we can do if we want to be in good.
　　First, we should have the right food, because proper nutrition is the most important for good health.Avoid foods with lots of sugar and fat. Eat plenty of high protein foods, vegetables and fruits. Do not overeat. Secondly, we should get proper amount of sleep, because without enough sleep, we will often feel tired and irritable. Allow ourselves at least eight hours of sleep each day. Have a nap at noon if time permits. Finally, we should exercise regularly, because'life depends on exercise'. Regular exercise strengthens our hearts andlungs. In addition, it prevents us from putting on weight.
　　If everyone is to do so, there will be much less complaining about poor health and there will be much more happiness in our life.
