Pay a visit to your local gym, observe the grimacing patrons as they pound the treadmill or march in place on the StairMaster, and you might conclude that exercise is no fun. But it doesn’t have to be that way, according to Kelly McGonigal, who lectures at Stanford, teaches dance classes, and wrote “The Joy of Movement: How Exercise Helps Us Find Happiness, Hope, Connection, and Courage.” Today, she explains how exercise — of all kinds and in all doses — can strengthen your mind, elevate your mood, and deepen your social connections.

Kevin Kelly has made a career out of looking to the future. He helped pioneer online social networking all the way back in the 1980s, and he co-founded Wired, the magazine devoted to digital technology, when the internet was still an infant. But in his new book, “Excellent Advice for Living,” he looks backward. It’s a collection of 450 bits of wisdom he wishes he’d known when he was young. Things like “Being enthusiastic is worth 25 IQ points” and “That thing that made you weird as a kid could make you great as an adult—if you don’t lose it.” Today on the show he shares his best advice for building careers, nurturing relationships, solving problems, and finding satisfaction. He also explains why he’s more optimistic than ever about technology (yes, even AI). P.S. Have you checked out our new audiobook, "Immortality: A User's Guide" by Steven Johnson?
