We all know exercise is key to a healthy life but that’s easier said than done, especially for medical professional who work long shifts and put all their time into caring for others. That’s exactly why Mass General Hospital has launched a month-long challenge asking staff to exercise 30 minutes for 30 days straight. The goal is to raise awareness about how to lessen the odds of dementia and stroke—the two leading causes of death in the U.S.

Doctor Lee Schwamm, vice chair of neurology at Mass General, which is the department behind the effort, joined Jim to talk about the challenge.
