Sports are conducive to health. First,they stimulate blood circulation. As a Chinese saying goes, "Running water is never stale and a door-hinge never gets worm-eaten. "Good blood circulation can prevent diseases. Besides,sports help digestion. If one often takes exercise,he will not suffer dyspepsia. Most important of all, sports make one energetic. One who takes exercise everyday is always full of vigour and will never be listless.
However, there are also disadvantages for taking exercise. First, if one takes exercise in the morning,he will sweat but he will have to go to work with wet underwear in a hurry, which is harmful to health. Besldes, it is also time-consuming to take exercise. If one takes exercise regularly, he can keep fit but most probably he will lag behind in other fields. Worst of all,if one takes exercise without taking in enough nutrition, his health will run down for malnutrition,which is just the opposite to what he wishes.
