Red crayons

You might wonder why blonde nurses bring red crayons to work.

It's in case they have to draw blood.

A comment from reddit user - Ethyques:

Any crayon would work if it's sharp enough. Otherwise it would be pointless.

Julius Cohnheim

Born 20 Jul 1839; died 15 Aug 1884 at age 45. Julius Friedrich Cohnheim was a German pioneer of experimental pathology who helped determine the morbid changes that occur in animal tissue affected by inflammation, tuberculosis, and other disease states. He demonstrated that inflammation was an active dynamic process. He was the first to scientifically classify tumors the way we still do today (ex. carcinomas, fibroma, sarcoma). Cohnheim proposed the first great theory of cancer's origin, the theory of embryonal rests. He thought more germ cells are produced with a developing embryo than are needed to form any given part and that cancer's development involves this excess material.
