Laughter is a pleasant topic to discuss. We laugh without knowing why we do it. The greatest advantage of laughter is that it binds(联合)people together. One piece of research shows that only 10-20 percent of our laughter is actually caused by jokes. Many times, laughter is caused by a person, not by a joke. Even if it is a joke, many people cannot give any particular reasons why it awakens their laughter. The gender(性别)differences in laughter are very large, too. Females laugh more than males. Throughout history and in all cultures, it is the men that are more likely to cause laughter. Try to remember who is the funniest person in your class or workplace. Perhaps it is a man. Maybe that is why there are more male comedians. Women seek men who make them laugh, and the men are eager to fulfill this request. Some say that laughter is the best medicine. This develops from the fact that laughter unites people and improves our mental and physical health. Also, pain reduction is another thing that laughter can guarantee. People who laugh during some procedures are able to tolerate more discomfort than those that don't laugh. The same is true with patients—the ones that watch funny videos need less medicine than those that don't. Another advantage of laughter is that it makes us less stressed. This explains why people laugh when they are nervous. Furthermore, laughter helps us to think more creatively. It encourages us to think about things in unusual ways. An interesting thing is that people laugh more if their boss tells a joke rather than an ordinary workmate. Usually people laugh about 18 times a day, but of course, it varies from person to person. Laughter is related to mood and personality. People who laugh more deal with stress more easily in their daily lives and they live longer and more healthily.
