I hear you loud and clear regarding guitar playing and increasing age.
I have found a lot of comfort in backing off a bit from the more difficult pieces. I play mostly country classics. I put on a CD and Jam with the stars.
Since I don't play the circuit anymore, I find this a wonderful pasttime. I Had trouble with the weight of my guitar on my neck, (especially my electric guitar) so I adjusted the strap so that it is evenly balanced between my neck and my leg. The strap just more or less just holds it in place.
Happy picking
Jim
