关于婚姻的十个有趣真相

Girl Power  女性权力  女性也能求婚！
Most modern marriage proposals are from men, but women actually do a small share of the asking, too. And they have Scotland to thank for starting the trend centuries ago: In 1228, it was the first European country where women earned the right to propose marriage, a law which then spread throughout Europe.

Criminal Minds  犯罪思想  婚姻能减少犯罪行为。
Maybe love really is all you need…at least to stay out of trouble. According to a 2010 study, marriage reduced criminal behavior in high-risk males by 35 percent. While the study's authors weren't sure whether calmer men were more likely to marry or whether marriage had a calming effect, we think the married guys just didn't want to explain those handcuffs to their wives.

Tie the Knot  结婚  传统的婚约是一生一世的承诺吗？
The term "tie the knot" comes from the pre-Biblical tradition of "handfasting," during which betrothed couples would join hands—his right to her right, his left to her left—in front of witnesses, signifying the couple is married for a year and a day. After the allotted time passed, they could then renew permanently or pledge themselves to each other for another year and a day, ad infinitum.

Ring Finger  戴戒指  婚戒为什么要戴在无名指上？
Wedding and engagement rings have been worn on the fourth finger of the left hand since ancient times. The Romans believed a vein in this particular finger, called "vena amoris" (a.k.a. the "vein of love"), leads directly to the heart.

Mind or Matter?  精神还是物质？  恋爱中的男女大脑会发生什么变化？
In a 2007 study, scientists found that men in love show more activity in the visual part of the brain, while women in love show more activity in the part of the brain that governs memory. Scientists theorize the difference has more to do with anthropology than biology: Men look for fertility features in women, and since women can't judge fertility in men by physical appearance, they must remember certain characteristics that will determine if he will be a good mate.
