Hi, new guy here. I'mm 55 (twice retired) I have aches and pains from serious injuries in and out of military. I'm still going though. I just have to take things a little slower and lighter. I just have to accept the fact that there is terrain that I can't cover, but I just adapt, stick to slightly less strenuous trails. I'm not missing anything though. Lots of beautiful terrain for backpacking/hiking/camping, right here in KY. In the early 70's I was stationed at Denver CO. I miss the alpine trips, and tough trails with the associated payoff's, truly majestic scenery and lot's and lot's of room.

But I can find beuatiful spots in terrain that I can still handle. So, my advice to you is to keep it up, if you love it as much as I do.
