Drunken argument...

Two drunks are walking along. One drunk says to the other, "What a beautiful night. Look at that moon!"

The other drunk stops and looks at his drunk friend. "You are wrong. That's not the moon; that's the sun!"

Both continued arguing for awhile when they came upon another drunk walking along. So they stopped him and said, "Sir, could you please help settle our argument? Tell us what that thing is up in the sky that's shining. Is it the moon or the sun?"

The third drunk look at the sky and then looked at them and said, "Sorry, I don't live around here."

Otto Meyerhof

Died 6 Oct 1951 at age 67 (born 12 Apr 1884).Otto Fritz Meyerhof was a German biochemist and corecipient, with Archibald V. Hill, of the 1922 Nobel Prize for Physiology or Medicine for research on the chemical reactions of metabolism in muscle. In 1940 he emigrated to America. Meyerhof demonstrated that the production of lactic acid in muscle tissue, formed as a result of glycogen breakdown, was effected without the consumption of oxygen (i.e., anaerobically). The lactic acid was reconverted to glycogen through oxidation by molecular oxygen, during muscle rest. This line of research was continued by Gustav Embden and Carl and Gerty Cori who worked out in greater detail the steps by which glycogen is converted to lactic acid - the Embden-Meyerhof pathway.
