Shoulders, grrrrrr!!!
What finished mine was a ring refusing to hook onto the masthead. I tried over and over, rotating and yanking harder and harder on the halyard until I heard a snapping sound in my shoulder. Bad plan.
Two years since my rotator cuff surgery and it's 95% of my 30 year old shoulder (notice I did not say 18 year old shoulder). Without hesitation I will play catch with my son, including long throws from center field. I haven't been able to do that for years so the surgery was great for me. It took 6 months before I'd race in big air, however.
