I think this is key. I never had too many issues taking breaks, to be honest. Even when 'programming', I spend a lot of the time thinking about what to do, and not actually typing. I heard early on that if you're constantly typing, you're doing it wrong, and I must've taken it to heart. I'm 44 myself, and fortunately haven't had that sort of pain in my hands/wrists/forearms. Have had back pain though, and that sucks.
