There is an old saying in English： "Laughter is the best medicine". Until recently， few people took the saying very seriously. Now， however， doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health.
There is also some evidence to suggest that laughter helps the body's immune system， that is， the system which fights infection. In an experiment， one group of students watched a funny video while another group served as the control group - in other words， a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells， that is， the cells which fight infection.
