Training for that half-marathon may lower your risk of developing cataracts and age-related macular degeneration (AMD), according to research from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. The key seems to be vigorous exercise.

Experts think running may help curb inflammation that might contribute to cataracts and AMD.
