Advice for small timers

Hi all, I’m new here and just posted in the intro forum. As stated, I used to scrap a lot but due to a spine condition I’m pretty much slow with limited use of my left hand. I do save cans and strip copper sometimes, I was wondering if anyone had advice for someone in this situation? I am mechanical and can use small tools. Each day is different so some days are awful, some days I can get around in short spurts well. Anyway, I’m not on Dr Oz and we talking metal. Sorry for the story. I’d be much thankful for any input. Much gratitude, mark
