MK, good point! Years ago I met my old doctors son. He claimed those old floor scope machines in shoe stores like buster browns, steralised him! When I was a kid around 1947 I was playing with my mothers old wringer washing machine. It would chatter like a machine gun if ya did it right. I was mowing down krauts and my hand got grabbed by the wringer! It took my arm all the way to the elbow and either broke or mom stopped the machine at the same time! It did leave me with a disfiguered wrist to this day. My folks were poor in those days and had no medical insurance. They took me to a shoe store that had one of those machines, had me lay on the floor and put my arm in and check for broken bones. It didnt leave me sterile, but I do belive it stunted me!
