The Kidney That Was In 3 People – And Other Amazing Science Things

My AMA is running right now: http://www.reddit.com/r/IAmA/comments...

In which Hank discusses some of the coolest things he's learned while answering people's questions about the world. Often times, I have to say, these questions start out with "This is probably a stupid question, but..." when really, any curiosity is good curiosity...and people who expect all people to know all things are the real idiots.
