from American College of Cardiology and British Journal of Sports Medicine
Two unrelated studies are related to longer lifespan in older people. The first study, presented to the American College of Cardiology, found greater fitness after age seventy was a better predictor of survival than the number of cardiovascular risk factors. In short, doctors at Johns Hopkins School of Medicine say a person who is more fit may be likely to live longer than someone who is less fit. The second study, in the British Journal of Sports Medicine, suggests it is not as important to be super fit—that even low-level physical activities, such as walking or gardening, are associated with a lower risk of death from cardiovascular disease, cancer or any other cause. Data came from nearly ninety thousand Americans from age forty to eighty-five.
