While it's common knowledge that frequent exercise is essential for maintaining good health, some earlier research has suggested that vigorous exercise may have the opposite impact.

According to a recent study that was published in the British Journal of Sports Medicine, those who engage in intense physical activity may live longer.

Researchers discovered that a small group of exceptional runners who could complete a mile in under four minutes may have an average lifespan five years longer than the overall population.

Because of their prolonged aerobic effort, professional athletes are known to have larger hearts. While some people thought this may have an impact on their longevity and health, our research showed the contrary.

Five extra years of life over the average is a big deal, especially considering that many of these runners were healthy as well as having long lives. They have longer, better lives.
