When a doctor gives you a prescription, you usually go to the pharmacy to get it filled. But research shows you could skip the pharmacy and go straight to the gym. This hour we'll talk about exercise as both prevention and cure. We'll also discuss the diet and fitness stories making headlines in 2013, and Obamacare's ever-changing deadlines.

Guests:

Alexandra Sifferlin, reporter for Time Health & Family

Dr. Jordan Metzl,MD, author of The Exercise Cure: A Doctor's All-Natural, No-Pill Prescription for Better Health and Longer Life

Mary Agnes Carey, senior correspondent for Kaiser Health News
