My maternal grandfather was a carpenter and farmer all his life in rural Illinois. In his 70s he was still farming his 80 acres.
He had the strongest hands I ever saw, and they were huge, too. If we acted up at the dinner table when visiting him,
he would catch his index finger on his thumb and "flick" us on the side of our head, saying "Settle down," in a quiet voice.
I'll tell you, when I was 10 or 12 years old, it felt like I got hit with a rock!
