I ran across this intersting article on MSN today. Although I certainly do not buy into some of the points they made in the article, I thought a few other of them were quite amusing:

The secret to a romantic night is…
So it’s date night and you want to set the mood for romance…what’s the right plan to make? Interestingly, you should go to a movie, but not any old flick. If you want kisses after the credits roll, then a romantic chick flick should be your choice, according to a recent study by the University of Michigan. Researchers reached this conclusion after testing the hormone levels of three different groups of men and women who were shown a variety of movies. One group watched a romantic scene from The Bridges of Madison County, a second viewed a violent portion of The Godfather: Part II, and a third was shown a documentary on the Amazon rainforest. While the viewers watching the rainforest footage experienced no hormonal changes, researchers found that The Bridges of Madison County caused a surge in both men’s and women’s levels of progesterone, a hormone that triggers the urge to cuddle. “Progesterone is known to have anxiety-reducing, soothing effects,” explains Oliver C. Schultheiss, associate professor of psychology at the University of Michigan and co-author of the study. In this way, progesterone can pave the way for romance and help couples bond, he says.

The best time to bond
Many people agree with John Gray—men are from Mars, and women from Venus. However, a new study suggests that there is a brief time in our dating lives when men and women are pretty much from the same planet. It's when we first fall in love. For this, you can thank your hormones, which, researchers from the University of Pisa in Italy found out, fluctuate like mad when a new relationship blooms. When guys are smitten, they experience a drop in their body’s levels of testosterone, a hormone linked to aggressive, sometimes domineering behavior. Meanwhile, love-struck women get a testosterone boost.

"Men, in some way, become more like women, and women become like men,” researcher Donatella Marazziti explained. And there’s a very good reason for this hormonal gender-bending: We’re more likely to have a rapport with someone who shares our personality traits. This blissful, two-peas-in-a-pod feeling doesn’t last forever, though. When researchers tested subjects one year later, they found that men’s and women’s testosterone levels had diverged and returned to their pre-relationship levels.
