Well when you put it that way, why I play anything on PC keyboard is because after breaking my right hand like thrice I can't use any gamepad comfortably anymore. My left hand only suffers from older age I guess. For example the damage done after playing a game via PlayStation 2 gamepad for 12 hours now happens to my left hand when I play a game for like one hour. My hands are too big for gamepads designed for kids and I know no gamepd designed for man-sizes so keyboard is the way lol!!! Only in that context to prevent damage I sometimes don't go too wild playing games anymore and it reduces my skill yep.Aside from some issues with my joints that limit the amount of time I can spend per session of playing really input-intensive games I haven't noticed much degradation, but I definitely have way less patience.
Back in the day I would just hunker down and chip away at a challenge until I eventually got it right, but these days I find myself getting annoyed much quicker. Which honestly bothers me and I am working on changing it, but it's definitely a thing.
