40 Not Too Old to Start Exercising.
Men who start exercising after age forty are likely to experience the same long-term heart benefits as those who have exercised since early adulthood. Study author David Matelot adds, “It’s never too late to change your way of life and get more physically active. This will always be beneficial for the heart and well-being. And there’s no need for a high level of training for many hours a week. Using the stairs rather than the elevator, or gardening regularly, can also be beneficial.”
