Married 25 years, I took a loo...

Married 25 years, I took a look at my wife one day and said, "Honey, 25 years ago, we had a cheap apartment, a cheap car, slept on a sofa bed and watched a 10 inch black and white TV, but I got to sleep every night with a hot 25 year old blonde.
Now, we have a nice house, nice car, big bed and plasma screen TV, but I'm sleeping with a 50 year old woman. It seems to me that you are not holding up your side of things."
My wife is a very reasonable woman. She told me to go out and find a hot 25 year old blonde, and she would make sure that I would once again be living in a cheap apartment, driving a cheap car, sleeping on a sofa bed.

Vitamin A

In 1947, the first full synthesis route for vitamin A was found by Dutch chemists, Jozef Ferdinand Arens and David Adriaan van Dorp. Later in 1947, a team headed by O. Isler also synthesized vitamin A using a method more suitable to produce commerical quantities. In 1913, Thomas B. Osborne and Lafayette Mendel had shown experimentally with rats that butter contained a factor responsible for growth development. Their work was confirmed (1913) by Elmer McCullum and Marguerite Davis who also identified a fat-soluble nutrient in butterfat and cod liver oil. It became known as vitamin A, and its chemical structure was determined in 1931 by Paul Karrer.«(Ref Arens and van Dorp, Synthesis of Vitamin A aldehyde, Nature 160: 187, 1947)
