A few months from now will be the anniversary of Albert Einstein's birthday. He was born March 14, 1879. Few remember that the Nobel Prize winner married his cousin, Elsa Lowenthal, after his first marriage dissolved in 1919.
He stated that he was attracted to Elsa because she was well endowed. He postulated that if you are attracted to women with large breasts, the attraction is even stronger if there is a DNA connection.
It was called Einstein's Theory of Relative Titty.
