I must contemplate this statement. It is deep--it calls for a full talmudic discussion...
But, there is an old Jewish saying which may shed some light on the subject, to wit:
Better a full-breasted woman than a Rothschild.
Although I may offend some folks, but it has been my observation that Jewish women are disproportionately well endowed, compared to ladies of other stripes. That's, as always, a good thing.
I have heard about the link between breast size and self-esteem before. Then again, they also say that men lacking below the belt tend to "overcompensate."
