Put in 15 Minutes of Exercise, Live Longer

It just takes 15 minutes of brisk walking, cycling, or swimming to help older adults live longer according to a study in the British Journal of Sports Medicine.

People over 60 can cut their health risks by a little more than 20 percent from even a small amount of exercise.

Lead author Dr. David Hupin, with the Department of Clinical and Exercise Physiology at the University Hospital of Saint-Etienne, France, said scientific evidence is starting to show that replacing sitting around with even some light physical activity can bring health benefits, Reuters reported.

"Age is not an excuse to do no exercise," Hupin said.
