Aired: February 2009
This document was interesting enough to rate and bring up, as readers of romance in all it's genres, the one common nominator is the sex and paring up the couple. What makes couples get together, what do they response to?
I liked the part where the documentary talks about females as the more ornamented sex, where males have cars, competition, status, wealth that can fracture into which mate women pick - women being choosier as they have more to worry about with the chance of getting pregnant, whereas men are more likely to hit on anything they find attractive.
One of the funniest part about this documentary was study on how women and men perceive the opposite sex's attraction to them. Men's assessment of woman's interest in them was always medium to high, women's the opposite.
Also fair warning men's saliva includes testosterone, a lust hormone, so be careful about who you kiss. ;)
