Walking – A Pedestrian Pursuit
A special hour devoted to something our species spent millions of years evolving to do — something our bodies are meant to do — and that we've spent the past century trying to do as little as possible: walking. We'll hear from evolutionary biologist Daniel Lieberman on how humans became bipedal and from psychologist Alexandra Horowitz, writer Wayne Curtis and urban designer Ken Greenberg about the psychological, social and economic benefits of walking and why, after decades of being degraded by our car-centric culture, walking has been making a comeback.
