Lynn and Tim’s first guest today is Harvard professor and cognitive scientist Steven Pinker who presents the big picture of human progress: people are living longer, healthier, freer and happier lives and says solutions to humanity's formidable problems are within our grasp. Then, a rebroadcast interview with Kevin Hines, who spoke in Park City last year about his book, Cracked, Not Broken: Surviving and Thriving after a Suicide Attempt.
