I'd like to sit here and tell you looks don't matter. That "what's on the inside" is all other people value in you. That true love happens in a vacuum filled only with snuggles and cuddles, void whatsoever of receding hairlines and breast sizes.

I'd also like to tell you the women on the "The Girls Next Door," the reality show about Hugh Hefner's three girlfriends, are hideous because they're cosmetically and surgically altered.

But in those cases I'd be lying. I'm an American — show me some skin and then I'll decide if I like you. (And by the way, how much money do you make?)

All humans are fixated by money and sex. Some cultures, like those we tend to go to war with, try to make money and sex as scarce and limited as possible. But in America we combine money and sex, turn it into a reality show and cause parents across America to shuffle their kids out of the room when it comes on. (No worries, the kids will catch it later on DVR.)

A show featuring women who don't seem to like wearing clothing is fine with me, especially when that show occasionally airs in my living room because my girlfriend, oddly, finds it amusing.

But the American money-sex machine gets a bit creepy when a T-shirt recently on sale at Abercrombie & Fitch — a store aimed squarely at the under-18 set — had these words across the front of the chest: "Who needs a brain when you have these?"

Part of America thinks Hugh Hefner seems old and innocent in his red robe. Could he and his quaint magazine really be that bad? But the rest of Americans connect Hugh Hefner to Abercrombie & Fitch to Paris Hilton, because it's really not that much of a stretch — and it scares them to stay up at night worrying about their children's future.

The question is whether it's normal that looks — particularly women's looks — are pretty much the most important quality an American (particularly a female American) can have. Is this human nature? Or have we just become obsessed with skin?

It's been assumed since Darwin's days that it's natural; that our brains are wired to find the best-looking mate in order to have attractive offspring — who would therefore be more likely to survive. We're inherently egomaniacs, and we want to live forever.

Recent research has confirmed this. The University of Essex studied 84 speed-dating events throughout England and found that every inch of a man's height increased by 5 percent women's interest in meeting him.

Meanwhile, clinically overweight women were picked by 70 percent fewer men than average-sized or clinically underweight women.

Other researchers, according to the Woodrow Wilson International Center for Scholars, have found human beauty triggers the same section of the brain activated in drug addicts when they're about to take a hit.

Two-month old babies have been observed looking longer at more traditionally attractive faces. And mothers of less attractive babies spend a disproportionate amount of time looking at other people in the hospital room instead of their own babies.

But other evidence shows it's not natural at all, that we have artificially inflated the importance of looks. The University of Texas did a study every 10 years and found the value of good looks has increased tremendously for both men and women. In 1989, men's looks were more important to women than women's looks were to men in 1939.

But wait! Men shorter than 6 feet and women over the 100-pound mark can take heart. Biologists have identified a number of animals that don't pick mates based on attractiveness. The peacock with the fancy feathers doesn't necessarily get more peahens than the peacock with the lame feathers, as originally thought.

And other studies show women base their opinion of attractiveness not on looks, but clothing.

Yes, I guess that's still shallow. But at least a nice suit or skirt is cheaper than hair plugs or silicone. And that means you'll have more of what really, truly matters in life and love: money.
