Live from SF Sketchfest, we've got Dr. Cynthia Kenyon, a geneticist who discovered a technique to make mice live seven times as long as normal. She's currently working on the science of human life extension. Comedians Wyatt Cenac, Phoebe Robinson, and Nato Green try to guess what she studies and then learn about what she does in the lab all day. Hosted by Chris Duffy.
