    Do you want to keep away from colds? You must say, "Of course". Now, first, please put on a happy face.

        A new study shows that happy and relaxing people seem to fall ill less often than those unhappy people. "It's possible that being happy helps the body fight illnesses," said the researcher Sheldon Cohen from New York University(大学). In an earlier study, Cohen found that cheerful and lively people caught coughs and colds less often. People's feelings seemed to affect their health. In this study, Cohen interviewed(采访) 193 adults(成人) every day for two weeks. During the interviews, the people told researchers that the doctors asked them to stay alone in a room for six days because of the cold.

        The results showed the people who said they felt happy during the research period, their illness were less serious and lasted for a shorter time. Cohen believes that when people have good feelings, their body may make a chemical, and it can help fight illnesses and diseases.

        So if you are worried about your health, look on the bright side more often. Just as the old saying goes, "A coin has two sides".
