I'm sure some of you have had it much worse than me. That said, at 41, I feel old. All my joints hurt, all the time.

Arthritis in my hands and fingers.
I've broken all of my fingers except my left thumb, most of my toes, and had some teeth knocked out (one of my front teeth is fake).
Damaged knees, meniscus problems (from skiing).
Busted up a foot real good, still short about 25% in flexibility in my right ankle.
Broke both hips the same time I busted my foot. The landing from a rock climbing fall was bad.
My right shoulder has dislocated several times (also rock climbing), and I have accompanying nerve damage in that shoulder.
Nerve damage in my hands and wrists from shooting way too many .45's over a 3 year period (well over 200k rounds).
And now I am recovering from surgery to repair an inguinal hernia.
Not to mention the face plant I did about 2 weeks ago on the hood of a car after a woman didn't see me at an intersection (she was at a stop sign, no traffic control devices for me in the direction I was riding), this resulted in the death of my Colnago MasterXLight frame, fork, and Campy shifters.
