1/18/2014 - STRESS - Stress may save your life if you're being chased by a tiger. But if you're stuck in traffic, it may be more likely to make you sick.

Stanford University neurologist (and part-time "baboonologist") Dr. Robert Sapolsky takes us through what happens on our insides when we stand in the wrong line at the supermarket, and offers a few coping strategies. Plus: the story of a singer who lost her voice, and an author stick in a body that never grew up.
