A new book is out dealing with women's breasts. (Breasts: A Natural and Unnatural History, by
Florence Williams).
A delightful review of this new book may be found here. About six hundred years ago, according to the review, Henri de Mondeville wrote to the King of France,
"The reasons why the breasts of women are on the chest, whereas other animals more often have them elsewhere, are of three
kinds. First, the chest is a noble, notable and chaste place and thus
they can be decently shown. Secondly, warmed by the heart, they return
their warmth to it so that this organ strengthens itself. The third
reason applies only to big breasts which, by covering the chest, warm,
cover and strengthen the stomach".
Also, according to the review, men viewed large breasts as a sign of a desirable woman for breeding. It is not recorded how women over the ages have looked upon that premise as a basis for mating. Also when women started having breast implants they had the last laugh on the men. As George Carlin used to say, "Women are crazy. Men are stupid. And men are stupid because women are crazy."
