Injuries are going to happen that's the nature of the beast. This year I slammed a rock with my hand so as to avoid taking it to my face. After riding for half my life my wrists are fucked from mangling them doing hand plants, push offs, miller flips, catching edges, messing up on jibs, and my shoulders aren't any better. Shit is going to happen, would a lesson have helped me? Not in the slightest, sometimes you just get too gnarly for your own good.
