despite some of the weird shit he says, he's certainly got a genuine, human side that people can very easily relate to.
I'm not overly surprised at the control he has over his body to be honest. I've been able to control my body in really cold, and I can control my heart rate really well too.
Not as well as him, but I don't train for it.
Some of the stuff he does, as interesting as it is, is possible by his breathing, but also equally enabled by a state of mind as well
