Dr. Mike Evans makes a compelling case for exercising 30 minutes per day in this well done 9 minute video. It's the single best thing you can do for your health.
Dr. Evans is the founder of the Health Design Lab at the Li Ka Shing Knowledge Institute and a professor at the University of Toronto and a staff physician at St. Michaell's Hospital. (I'd like this even if he had not mentioned Steven Blair from the University of South Carolina. Go Cocks!)
Many thanks to Bill Baulkwill for sharing this with me.
