Ron White has a great bit that goes something like, "Titties. Once you've seen one, you want to see the rest of them". He means, of course, ALL of them.
I'm more of the belief that some things, like mortal injuries of accident victims, toothless old men's smiles, and 50 year old boobies, should never been seen by anyone except for licensed professionals. Otherwise, there can be permanent harm done to the psyche of the person who catches a glimpse.
I mean, I'm keeping the girls out of your view purely for your own self interests.
We should all be so lucky as to grow old. We may as well get used to them now in case we do.
