1. I love Radio Lab.
2. Did they talk about what percentage of blood donations go to which uses? I once read/heard that something like 75%+ of donated blood is used for uses other than transfusions (anti-venom, vaccines, etc.). Back when this was fresher in my mind I would occassionally mention it to other JWs and follow it up with something like "does that mean JWs could donate blood if it was guaranteed your blood was being used for pharmaceutical purposes, and not transfusions?" Their response was always funny to watch, because if they say "no", they sound like a selfish idiot because they would/can except any of the products derived from all that donated blood; if they say "yes", it would be tantamount to accepting a straight blood transfusion in many JW's eyes.
