^^^^ FWIW, first I didn't read Grump's comment on MMA as being directed especially at you. He was simply setting up an analogy about different ways of approaching skiing. Second, I din't read q's comment as pedantic (go look up the term). Third, I did read Grump's comment about rethinking things as being self-referent; he was wryly making a comment about his own way of doing things. Fourth, it's not clear to me - as someone who does gates every damn weekend - that there's any evidence that challenging ourselves is more dangerous than not, unless we're in Lindsey Vonn territory. I just got a decent injury not by challenging myself on a course or the steeps, but getting careless at speed in bad snow on a stupid runout. A patroller buddy says she sees more injuries in good skiers from that than from attacking difficult stretches, where all systems are on high alert.
Fifth, real athletics are always a cost benefit analysis. As q says, if a member here is hitting big terrain, day after day - and factor in age here - the benefits of constantly pushing our bodies to 9/10 may not be worth the costs. Especially if that member already is an accomplished skier. I watch videos of guys like Sierra Jim, who's forgotten more about mechanics than you or I will ever know, and I see a guy who's fluid, under complete control, and enjoying himself at a point when we don't heal as fast as we did at 20. He could still smoke you or I without breaking a sweat, BTW. I see the same thing when I watch 40-something instructors who depend on teaching for a chunk of their income. Comprende? "Challenging" ourselves constantly is neither a necessary or sufficient condition for being a good skier. It does, however, tend to characterize a lot of so-so skiers I see who think energy will emerge victorious over skill.
So chill, stop assuming everything's about you, and go, ah, hit those challenges. Your bindings will save you.
