There you go. I'm not too good with heights. I found both those videos literally terrifying. Theres no way in hell I'd ever do that. I've had many dreams about being up high and I always shit myself. Sometimes literally.
The second video is just all kinds of messed up. Theres no amount of money in the world that would convince me to do that. Seriously.
I watched that second video twice because the first time I saw it I thought the guy who is hanging upside down must have a harness on, but outside the view of the camera. I couldn't find any evidence of it.
Nuts. Just nuts. It's like one wrong move and you've probably got 3-4 seconds to think about if you'll feel any pain before you die.
