For Beyond 50's "Medical" talks, listen to an interview with Dr. Abigail Baird of Vassar College and part of the National Geographic Channel series called "Brain Games." She'll explain about the brain's evolutionary predilection toward doing the wrong thing. From guilty pleasures to vicious vices, you'll learn why we're drawn to behaviors that ruin us, how to fight back against enticing evils and why some negative emotions are actually critical for survival. The brain can switch to anger even when it should be perfectly happy. And, an exploration on lust and what drives the brain wild.
