Also the fact that he’s never hurt himself bad enough throughout his life to keep him off a bike.

That's the difference in mindset between people who do an "extreme" sport and the visitors who take up the sport because of trends, or a passing curiosity. The visitors look at an obstacle, or trick and think "what if this goes wrong?". The doers think "how fucking cool would it be to land this?".
It's pretty damned demeaning to that dude's years of perseverance and practise, for you to brush it off as "he’s never hurt himself bad enough throughout his life to keep him off a bike".
I've had multiple fractures, plus proper broken bones, and a compression fracture of two vertebrae in my spine, over the years. I'm still out riding my bikes(mtb and mx), I'm still at the skatepark on my board(when I don't have the time to get to the trails), and I've been doing this since the mid 80's.
