Blondes' Darwinian Advantage

Faithful iSteve.com reader Nikki, who says she looks "like a Latin Dorothy Dandridge meets Jessica Rabbit type," writes to point out that while, as I theorized below, young blonde women may indeed have a Darwinian advantage in catching men's eyes, their edge fades:

While my [blonde] girlfriends admittedly wield what would seem to average looking girls of any race an enviable disproportion of sexual power in their teens and twenties, these Blonde beauties, especially the sun-goddesses, start looking a tad bit, well peaked, you know, past the sell-by date, once they hit their mid-thirties - unless they happen to be blessed with strong cheekbones and facial structure. Otherwise, Father Time does his cruel linear dance with crows' feet across Mother Nature's fair maiden's countenance, and watching that happen is heart-breaking without the aid of the Botox Wizard. It's like observing a nouveau riche tycoon devolving into a shopping-cart pushing crack head, not a sight for the faint of heart. Unless said fair maiden is married to a plastic surgeon like the fortunate Victoria Principal. I guess it all evens out in the end! YAY!
