The special ops episode made some interesting points/tests as well.

Hey, I saw some of that one, too. Interesting results in the desert/heat simulation with the Israeli officer. Despite a high body temperature of over 103F (32C), he was able to actually better his baseline performance in the agility test. I wouldn't have thought that was possible, but I guess there is still quite a bit we don't know about the mind/body connection.
