Math goes out the window

As a responsible citizen, I feel it's important to discuss the important issues that we as a society face on a regular basis, no matter how controversial they may be. In this case, the discussion that I'm proposing is: How young is too young?

Now before you simply blurt out the standard minimum-age formula (Your age/2 + 7 years), stop and look at the picture. Does age really matter that much? I found her at a reputable site, where all such models are 18 and over. That's pretty much good enough for me. I think that the law should decide for me, how young is too young. That way, no matter what random number I come up with using that bullshit equation, my conscience is clear.

By the way, I DID notice that her name is Kelli Young. Coincidence? I think not.
