Radiolab is the only podcast -- and yes, I'm including you, This American Life -- that never disappoints. The recent show -- An Illustrated History of Heimlich -- is an excellent example, a comprehensive story of the still-living doctor who invented everyone's favorite anti-choking device, and his somewhat bizarre medical legacy.
I used the Heimlich Manuever on my daughter once; she was four or five, it was at a church hot dog picnic. Only medical procedure I've ever pulled off with any success, so however strange Dr. Heimlich's other ideas are (like using malaria to cure AIDS) he's still a hero in my book. The Radiolab correspondent didn't sway me in that regard.
