Exercise — it's good for the brain

If you're still looking for reasons to get off the couch and get active, this study out of the Medical College of Georgia might get you thinking.

Researchers found that overweight children lowered their risk of diabetes and improved their ability to think after just three months of daily, vigorous activity. They studied 200 overweight kids and taught them about the benefits of healthy nutrition and the benefits of physical activity.

Turned out what he thought were shin splints that wouldn't go away during the race were stress fractures that took a long time to heal.

After that race, he said he'd never run another. A lot of people who run marathons will say that right after a race — when their legs have seized up and they feel like they can't take another step without shrieking in pain.
