| We may know some good health habits, but we don't realize how much difference they can make. In the 1970s, scientists at the University of California-Los Angeles asked 7,000 people about their health habits. Then they followed these people to see how long they lived. The scientists discovered that seven habits were closely linked with a longer life.
three or fewer of these habits lived another 21.6 years. People who had six or seven could expect to live another 33 years! But how do you change your habits? Make one small change every week. And be patient. It takes about 21 days to form a new habit. | |
