We all know that exercise is good for our health. But some kinds of exercise may be better than others.(1)Running, for example, may help protect against heart disease and other health problems. Running may also help us live longer. Researchers say it is not important how far we run. It also does not matter how fast or even how often we run. As advertisements for the running shoe Nike say, "just do it".
    Recently, researchers studied more than 55,000 adults. About one-fourth of the adults reported they ran regularly. The study found these runners were considerably less likely than non-runners to die of any form of disease, including heart disease.(2)In fact, the runners lived, on average, three years longer than the non-runners. Compared to non-runners, runners showed 30 percent lower risk of death by any causes, including heart attack, stroke or cancer.
