Not much to tell, really. As a dude in his mid-50s, I find it easy to overplay if I don't warm up and gradually get into a session or gig. I sit for a living, so posture is generally an issue, and put a 10lbs weight around my neck pulling me forward and it doesn't take long before I'm feeling it in my lower back.
So I have a little stretching routing I do before any session. Mostly upper body stretches (hand, arm, neck, back), and some warm up finger/picking exercises I do to get things going. I'll avoid the tunes that really require an effort until later in a set. I have back stretches I do nightly for the lower back. I find all this helps a good bit to avoid feeling like I've "overplayed." Arm fatigue, tingling, pain. If I ever feel any of that, I'll let my arm rest a week and it goes away.
I don't gig a lot, 4-6 times between Memorial Day and Labor Day , so it's not a big thing to deal with the physical limitations in that context. Most of my playing is writing/recording, and that's where I'm finding myself impacted if I don't adhere to these routines.
