So there you are, enjoying a nice day, getting things done, when you get abducted by aliens, run over by a truck, flattened by an asteroid or you slip and fall on ice. I think that the number one reason people visit emergency rooms is cutting their hand while slicing a bagel, the number two is getting decked by a thug during a hockey game.
No. Number two is probably falling on ice, which I just did, and my throwing arm, the right elbow and wrist, while apparently still moving and in one piece, are quite sore. Dammit to hell.
