61 Here.
None. I've been blessed and lucky!
I played a lot of competitive Hockey and came out with 6 stitches, 2 sore knees, 2 sore hands, and assorted other aches and pains. I was a slalom and barefoot waterskier until almost 50, and played most every sport as a kid. I was always very lucky! I was always involved in fairly high risk activities and always somehow avoided serious injury. I try to never complain about normal aches and pains of growing older and paying for the sins of my youth.
I can not imagine all the pain and suffering some have been through......
