At the start of each new year, broken resolutions start piling up like cars on an icy road. So it's a great time to talk with author Jeremy Dean, whose new book Making Habits, Breaking Habits: Why We Do Things, Why We Don't and How to Make Any Change Stick, examines the psychological aspects of habits and routine. "Probably the vast majority of our habits are good ones, and they're getting us through our everyday lives," says Dean. But how do we break bad habits? And how do we fall into them in the first place? AARP Radio host Mike Cuthbert talks to Dean about making, and breaking, habits.
