Three old men

Three old men are talking about their aches, pains and bodily dysfunctions.

One 75-year-old man says: "I have this problem. I wake up every morning at 7 a.m. and it takes me 20 minutes to pee."

An 80-year-old man says: "My case is worse. I get up at 8 a.m. and I sit there and grunt and groan for half an hour before I finally have a bowel movement."

The 90-year-old man says: "Not me. At 7 a.m. I pee like a horse and at 8 a.m. I crap like a cow."

"So what's your problem?" asked the others.

"I don't wake up until 9:00."

Julian W. Hill

Died 28 Jan 1996 at age 91 (born 4 Sep 1904).Julian Werner Hill was an American chemist was a U.S. research chemist who discovered cold drawing, a technique of strengthening polymer fibers by stretching. Julian Hill and Wallace Carothers had been building long polymer chains by a reaction of a carboxylic acid with an alcohol to give an ester in a device called a molecular still. While removing a sample of the resultant product from the still, Hill observed that the molten polymer could be drawn into fibers. He then made an important and unexpected discovery - that after being cooled, these pliable filaments could be stretched or "cold drawn" to form very strong fibers. Further tests on the sample showed that it had a molecular weight of over 12,000, far higher than any previous polymer.
