In this very special episode, we bring you our KPCC live show from Los Angeles. In the first half, we speak with the brilliant science writer Jennifer Ouellette about serendipity, cultivating openness, and what makes us who we are. Plus, jiu jitsu, Buffy the Vampire Slayer and much more! Then we pass the mic to American Public Media’s The Mash-Up Americans for a different take on identity… and mezcal!
