I think there's a ton that goes into doing shit stuff like this stunt and doing it for a living. You mentioned a lot of them and I would include stupidity, recklessness, I-don't-give-a-fuck-ness and more. Don't get me wrong, I really admire the level of professionalism these guys/girls trained for and reached but I can't help and wonder about the motive. Starting out with it on a farm means it certainly wasn't money. The term adrenalin junky comes to mind and I guess I'm just to old (and level-headed) to get that. That's okay and that does not keep me from admiring these stunt people. Indeed stunt doubles are also people I admire for their craft, they're probably underpaid though.

Where was I going with this? I have no idea, Just thought I'd comment my immediate thoughts. Hope you're having a wonderful Sunday!
