In my opinion, it is essential to do the following. First, it is absolutely necessary to take some exercise at regular time every day. Research shows that getting plenty of exercise can make the heart beat faster and the lungs work harder. This strengthens the heart, reduces the chance of heart attack, and helps lower blood pressure. That's why more and more people are becoming active in various kinds of sports and exercise. Every morning many people get up early and take much exercise. Some play ball games while others run, jog, walk or dance to music. In the afternoon, there are also many people keen on sports. Through sports and exercise, people become healthier and stronger. Medical researchers have proved that what people eat affects their health. They advise people to eat more fruit and vegetables and less meat such as beef and pork because meat contains more fat than poultry (家禽) and fish. Fat can build up in the arteries (动脉), block the flow of blood, and cause a heart attack or stroke (中风). Getting rid of bad habits like smoking and drinking alcohol is also an important way to keep healthy. Smoking and drinking alcohol injure one's health a great deal, and therefore should be given up. Unfortunately few people follow this advice.
