Factors Affecting Health
 Many 1aspects of our lives 2affect our health. One of these is how we eat. This is a subject that scientists are now studying. One study of the 3diet of Chinese people living in the countryside 4showed that they eat much more fruit, vegetables, and grains than most people in industrialized countries like the United States or Canada. They also 5consume three times as much fiber. These people get fewer calories from fat and eat meat only about once a week. The result? The rate of heart disease and certain cancers is very low.

 Another aspect of our lives that affects health is exercise. While the Chinese people in the study consume more calories daily, they are not overweight. Why? They do more physical work, and since most of them do not have cars, they walk or ride bicycles. Doctors everywhere now 6recommend exercise for people of all ages. Exercise helps control weight and 7relieve tension and stress.

 A positive mental attitude also seems to 8have a lot to do with health. Studies show that people with a good attitude about life seem to get sick less often than other people. Dr. William Fry, Jr., a Stanford University researcher, has 9studied the beneficial effects of laughter for many years. He says, "When we laugh, muscles are 10activated. When we stop laughing, these muscles relax." Many people with painful conditions 11benefit greatly from a healthy dose of laughter. Many headache sufferers feel the same relief.

  Your life is in your own hands … and the quality of that life also. You 12owe it to yourself to be beautiful, clever, thin, and healthy. If you fail, it's because you're not trying hard enough.
