Have you tracked your mood lately? You may want to after reading about a new study suggesting that happier people stay healthier throughout their later decades. An English study of nearly 3,200 men and women aged 60 or over discovered a link between a positive mental well-being and physical well-being. Researchers from University College London found that people who said they got the greatest enjoyment out of life showed slower declines in physical function as they aged. They also walked faster than people who reported that they enjoyed life less, and were better able to manage the tasks of daily living. People who had chronic ailments, like heart disease, arthritis and diabetes, reported lower levels of enjoyment. The researchers note, however, that happier people are not happier simply because they’re healthier, but they may be healthier because their happier. The study was published in the Canadian Medical Association Journal
