No Laughing Matter

Laughing is very good for our health. It makes people happier. I have watched one TV program about laughing and smiling before. A teacher showed some tests to Children. He divided children into two groups. One group just ran short distance with all of their strength. The other group also ran with all of their strength but they were asked to smile while they were running. The result of this research was that the latter group was faster than the former group. Besides, in same TV program, a doctor recommended one patient who had a serious lung cancer laughed loudly everyday. The patient tried to do that. Then about 3 month, surprisingly the cancer disappeared. I learned that smiling and laughing are very powerful.
