Years ago, my father, who was a very experienced clockmaker and woodworker in his spare time from being a pediatrician, was ripping a thin piece of board on the table saw... probably wasn't using a pusher or the featherboard... and had the piece kick back and hit him in the head. We assume, since nobody else was there, that he must have fallen forward, and ended up running the table saw clear down his left index finger to the last joint. They ended up having to take off the whole finger at the joint. He also drove himself to the hospital since nobody else was home... I miss the older generations... they were hardcore.
