Light jogging linked to longer life

Compared with not running at all, jogging even five to 10 minutes a day may be enough exercise to extend life, according to a study in the Journal of the American College of Cardiology. The study focused on more than 55,000 men and women ages 18 to 100. About a quarter of them were runners. Over 15 years, those who ran up to 50 minutes a week at a moderate pace were less likely to die from either cardiovascular disease (such as heart attack or stroke) or any other cause.

The study suggests a relatively low minimum daily "dose" of jogging to boost longevity, although people who run more than 10 minutes a day may enjoy a greater benefit. A 2013 study in Denmark suggested that the "sweet spot" for maximum longevity is 1 to 2.4 hours of running a week.
