Looking for the Fountain of Youth? Try the Gym
Smaha, who runs four miles a day, says lack of exercise is probably the second leading contributor to heart disease, behind smoking. Current American Heart Association guidelines call for 30 to 45 minutes of exercise three to five times a week, but new guidelines to be released within the next few weeks are expected to recommend some aerobic exercise every day.
"Maintaining an exercise program throughout life results in a better quality of life," Smaha says. "And this study shows that it is never too late to start."
Study participant Laszlo agrees. With three children who are athletes, including a 27-year-old son who competes in Iron Man competitions, Laszlo says he has plenty of motivation to keep active.
"I still work out, but I have to admit I think walking is boring," he says. "I do sports because it's fun. But it doesn't matter what you do as long as you keep your heart rate up a bit."
