53 and It sucks! You wear glasses,You don't have your balance. You can't run. And i can't even throw a baseball good now. Everytime i throw it bounces to the ground.
I'm 44 and have all that too. Of course in my case, it's due to cerebral palsy more than age, but still, I know how you feel.
As for aging, I've always looked older than I am, or so I've been told. I still remember how back in 1986, in the ninth grade, another kid my own age asked me "What is a 30 year old man like you doing in one of my classes?".
