NEW DELHI: For elderly people, 15 minutes of daily exercise can lower the risk of death by 22 percent, new research indicates.

"Age is not an excuse to do no exercise," said Dr David Hupin of the University Hospital of Saint-Etienne in France. "It is well established that regular physical activity has a better overall effect on health than any medical treatment. But less than half of older adults achieve the recommended minimum of 150 minutes moderate intensity or 75 minutes vigorous intensity exercise each week."
