I just received a press release that reminded me of a class I took the first semester of my freshman year in college called "The Biological Basis of Human Behavior" (otherwise known as "The Closest I've Ever Come to Getting a D" or "Wake Up! If You Keep Partying Like That, You Will Not Graduate").  It was from the publicist behind a new book called The Score: How the Quest for Sex Has Shaped Modern Man, who says author Faye Flam researched "the biological, evolutionary, physiological, psychological and cultural aspects of the male sex—and it turns out that a lot of what they do is actually driven by their need, or rather desire, to score."

Even though the concept brought me right back my days in Foellinger Auditorium—listening to the sound of Charlie Brown's teacher and praying for a few Advil to fall from the sky—he did list some of her key findings, which would at the very least make for fun, if not controversial, conversation starters:

• Men go for younger girls because a wife of nineteen can produce more children than a woman of forty.
• Men cheat because, up until fairly recently (evolution-wise), humans had to be promiscuous to further the species.
• Men typically want more chaste women because they're innately avoiding the trap of raising another man's young.
• Men watch more porn because they evolved from animals that would fight over females in heat.
• [Men are not the only animals to use wingmen; newts—among others—do, too.]
• When your boyfriend looks at a pretty girl walking by, he may not even realize he did it.

I'm hot. You're hot. He's hot. She's hot.

Emphasis on She's hot...
