We’re hard at work on new episodes of the TED Radio Hour, which will start rolling out in March. In the meantime, new host Manoush Zomorodi shares some of her favorite episodes of the show. This episode originally aired on March 24, 2017. Humans have a capacity to laugh even in the hardest of times. This hour, TED speakers describe how they use humor as a weapon and a shield, to ward off doubt, discrimination, and even depression. Guests include comedians Sandi Toksvig, Maysoon Zayid, Negin Farsad, and Kevin Breel.
