How much heat can the human body take?
Let's hear it for all the scientists who go first. Sure, being a human guinea pig has its risks, but life is never boring.

To hear all about their story and the beauty of sweat, listen to the piece by NPR's Robert Krulwich tonight on All things Considered.
Also check out the cool video version of the tale by Krulwich and animator Lev Yilmaz.
Just don't try this at home. Your dog may survive, but she'll hate you.
