Exercise offers so many health benefits. Something like walking for half an hour a day dramatically reduces the risk of heart disease, diabetes, and several forms of cancer, including colon cancer, one of the leading killers.

Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories. The more intense the activity, the more calories you burn.

Regular trips to the gym are great, but don't worry if you can't find a large chunk of time to exercise every day. To reap the benefits of exercise, just get more active throughout your day — take the stairs instead of the elevator or do household chores.

All of us want to have good health because we cannot buy health even we are rich. In my opinion, health is the better than wealth because if we were in good health, but not rich, we could do what we want, we could do hard work and serve ourselves in daily activies. Moreover, we could help others, bring happiness to them. With good health, we could interesting. Otherwise, if we were rich but not healthy, we would depend on others because we could not serveourselves in daily life, become other’sload, we are easy to be angry or bored with everything. In summary, healthis better than wealth.
