When we were kids, my older brother and I would watch professional wrestling and then have our own wrestling matches. My brother, being four years older and a good bit bigger than I, would always manage to get me into some sort of a hold that would result in my conceding defeat with a loud cry of, “UNCLE!” One of his favorite holds was the “hammerlock”. For those of you unfamiliar with wrestling, a hammerlock involves pulling your opponents arm behind his back and exerting upward force on the wrist forcing the hand up toward the shoulder blade. It can be very painful and one could, no doubt, break someone’s arm by applying too much upward force (no broken bones for me, fortunately).
