Speechless
Those videos are amazing. It leaves me speechless. An incredibly dangerous sport.
I would think all those people are reasonably single and live among a rarefied group of people because you just wouldn't "fit" into society because you would be bored by it's machinations. These are the ultimate adrenalin seekers. Not only do they have to be brave enough to do this, but they obviously don't care if they live or die. Playing dice with the Gods. (Maybe I'm just jealous.)
I think it's "pushing the envelope" to the max.
It would be fun to interview these guys and hang out with them.
You'd get a contact high.
