I highly recommend you listen to all episodes of this mini serie about medicine! The first episode is about our standard for perfect body temperature, namely: 98.6°F or 37°C. This number is based on research done a loooong time ago. The question is: is this number still right?
Episode 2 is about drugs. Especially about drugs that turned out not to be so helpful, harmful even. The last episode, episode 3, is about death by medical error.
