Derek is back, and ... he's a new dad! After several weeks of parental leave, he talks about what's surprised him about new fatherhood. Brad Stulberg, the health and science writer, returns to the show to discuss the psychology of major life transitions, why westerners—and, in particular, Americans—are so bad at dealing with challenges to their identity, and his new book, 'Master of Change.'
