You get smarter as you get older in terms of what's important (protect your body). Climbing a sheer cliff or very steep mountainside are things I don't want to do. Honestly. I think a could but I protect myself now as you start to realize that you don't heal as fast, rest up as fast (recover), or do what I consider "stupid stuff" just to do it. I do not jump off big logs or rocks.... Too easy to hurt yourself out in the boonies. I still like to wander around in the woods (off trail), but I suspect those days are somewhat numbered. If something happens, nobody will find you for possibly days.
Knife choices may change less as well as you become comfortable with what ya got.
I'll leave you with just one phase that will become more meaningful as you get to old fart age; "Help, I've fallen and can't get up!"
