As far as I know the following hypothetical experiment is mine. The assine braintrusts at Stanford and Oxford and such are too busy playing with rats. Maybe Cosmopolitan has done this, eh?

The Experiment:

Let's say there is a group of a 100 people, 50 men and 50 women. All single and all relatively "normal". OK, don't get crazy with me on this..."normal" men and women, kinda randomly chosen.

They meet once a week, in a social gathering for an hour or two.

Question:

At the end of, say, 3 months, how many (would you guess) of these men and women are now having sex?
