It's all good. Seriously, the knees only stop me from playing sports, everything else is pretty cool (except kneeling but who the fcuk cares?).
To be honest, and I'm not rationalising, I got a bit fed up with playing social sports anyway a long assed time ago. I remember almost every game was a damn hassle, making sure every bastard turned up on time, brought the correct uniform, and then we'd end up playing against retired footy blokes, who we'd beat by 20 points but would end up with chipped teeth (literally, both my front teeth).
Not good enough to play in a serious competition but too good to be playing amongst ferals. I had my moments in the sun, a few famous double handed board taps and ferocious chest shoves, but that's about it. I was fed up with it all before the knees.
