Host Frank Stasio talks with Dr. Bruce Greyson, a psychiatrist and former director of the Division of Perceptual Studies at the University of Virginia, about his research into near-death studies and what the experience shows about our brains. He also talks with Susan Amsden, group leader for the International Association for Near Death Studies in Durham, about what people near death experience, how it changes their understanding about life and death, and what the phenomenon tells us about the human desire to believe.
