A pious man who had reached the age of 105 suddenly stopped going to synagogue. Alarmed by the old fellow's absence after so many years of faithful attendance the Rabbi went to see him.
He found him in excellent health, so the Rabbi asked, "How come after all these years we don't see you at services anymore?"
The old man looked around and lowered his voice. "I'll tell you, Rabbi," he whispered. "When I got to be 90, I expected God to take me any day. But then I got to be 95, then 100, then 105. So I figured that God is very busy and must've forgotten about me, and I don't want to remind Him!"

Adding machine

In 1887, a patent for the adding machine was granted to Dorr Eugene Felt of Chicago, Illinois. His Comptometer was the first practical key-driven calculator with sufficient speed, reliablility and economic benefit. He called his original prototype the "Macaroni box", a rough model that Felt created over the year-end holidays in 1884-85. The casing was a grocery macaroni box, assembled with a jackknife using meat skewers as keys, staples as key guides and elastic bands for springs. Door improved his design, producing his earliest commercial wooden-box Comptometer from 1887 thru 1903, leading to the first steel case Model A (1904 that would be standard for the remainder for all "shoebox" models. Electric motor drive was introduced in the 1920's.
