In an angry, polarized world, it’s good to remember the many benefits of a good laugh. Chris Duffy is a comedian and host of TED’s podcast “How to Be a Better Human,” and he joins host Krys Boyd to discuss the link between humor and innovation, how social bonds are formed over jokes and chuckles, and why humor is a key to a happy, healthy life. His book is “Humor Me: How Laughing More Can Make You Present, Creative, Connected, and Happy.”
