It's too late for me to change. It's never too late to change. Studies show that sedentary people who adopt an active lifestyle receive a significant health benefit even if they've been sedentary for most of their lives. Changing from being inactive to being active is as important as changing other important risk factors for cardiovascular disease. I'm too old to be active.
Physical activity is a key factor in healthy aging.
The physiological decline associated with aging may actually be the result of inactivity. Perhaps the most important benefit of physical activity is that it enables people to retain their independence throughout the later years of life. One study suggests that people with higher levels of physical fitness and physical activity are less likely to develop the functional limitations often associated with aging. These include problems with personal care such as bathing, dressing, and feeding. Women don't benefit as much as men from physical activity.
