When I was a lad fresh out of college, a colleague was taking a shortcut to his car that involved vaulting the parking lot’s 5’ chain-link fencing. He did this every workday, so was quite adept at placing one hand on the crossbar and simply vaulting over. One day, a projecting wire of the fence cloth jammed itself between his wedding band and his finger and literally ripped his finger off, leaving it attached by tendon and skin. The surgeons were able to re-attach it but could not make it functional.
I was never one for wearing jewelry, but was proud of my college ring and fully expected a wedding band to join it eventually. I stopped wearing all jewelry that day, and now in my seventies have had many, many close calls with aircraft, shop tools, and other threats of modern life, with only surface scarring. My wife knew of this when we were dating and was fine with it. To this day, I do not wear anything attached to my body that is not safety-related.
