Ah; It's "Biological"

So is this saying that the real reason prostitutes, porn stars, groupies and the girl in high school that was nicknamed "The Town Bicycle" were/are so sexually charged is because of estrogen overload?

I think so.

"Results provide support for the relationship between physical beauty and fertility and suggest that women high in reproductive health engage in opportunistic serial monogamy -- being open to affairs and moving on to a new relationship if a higher-quality mate becomes available."

Uh-huh....anything else?

"Our results are consistent with the possibility that highly fertile women are not easily satisfied by their long-term partners and are especially motivated to become acquainted with other, presumably more desirable, men," they concluded.

I wonder if Larry Flint will use this as a argument to get his porn industry bailout.
