Thanks for the link. I particularly like this part:
The women's brain activities were a bit more puzzling.
The scientists found that women in love had more activity than men in the areas of the brain that govern memories. Dr. Fisher theorizes that this is a "female mechanism for mate choice." There are no visual clues for whether a man is fertile, but if a woman really studies a man and remembers things about his behavior, she can try to determine whether he'd make a reliable mate and father.
Thus, if it sometimes seems like a woman remembers everything -- good and bad -- about a man, "it's not just her being picky. It's an old Darwinian evolutionary strategy."
Now I know why I am good at 'kitchen sinking' during a conversation.
