Oh, you are still a kid! I'm 78 and still hiking; slow, but steady. A few years ago I met a couple of old guys coming over Piute Pass, at the end of their three week backpack trip,one of whom was celebrating his 87th birthday. Keep going dude!
On my weekly day-hikes on Bishop Creek I actually see more older women hiking than older guys. It's harder to find other senior males willing to get off their rears and into the mountains.
