Nowadays more and more people are worrying about their health. But how to keep healthy?Different people may give different answers to this question. In my opinion, it is important to do the following.
First, we should take exercise every day. Plenty of exercise helps us build a strong body and makes us work better. That is why more and more people are becoming active in different kinds of sports and exercises. In morning many people get up early and take exercise. Some practice running while others walk or dance to music. In the afternoon, there are also many people doing sports. Some play basketball or volleyball, others play football or badminton.
Second, have a healthy diet. Over-eat or too little food is very bad for our health. We should not eat too much or too little for every meal. We should eat healthy food, such as all sorts of grain, green vegetable and fruit. 
Third, give up bad habits like smoking and drinking. Because they are also bad for people’s health.
All above are my thoughts about keeping healthy. If we can do as them, we will become healthier and stronger.
