20 facts about Boobs

Cosmo says your fat? Well I ain't down with that. But, they do know their boobies! And, honestly it's almost as if BB blog was created because of Cosmo's own Boob(sans-ie) Bible. Did you know that an A-cup clocks in at only a quarter pound; a B, about half a pound; a C, three-quarters of a pound; and a D, around one pound? What about that sleeping face-down can make them misshapen over time? Or that the left boobie is usually the larger one?

Cosmopolitan decided to publish the Boob Bible because women tend to know way less about their precious treasures than you would think. As Cosmo says, "maybe it's because you've had your set for years now, and you view them simply as a bodacious accessory. Or your twin peaks seem so low-maintenance, you've never had a reason to give them much thought." For the 20 facts, click here.
