Few remember that the brilliant Mathematician and Nobel Prize winner, Albert Einstein, married his cousin, Elsa Lowenthal, following the dissolution of his first marriage 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 stronger if there is a DNA connection.

This has become known as Einstein's Theory of Relative Titty.
