There were real reasons that you were attracted to somebody originally. The brain doesn't pick willy-nilly. Unless you part ways hating each other for some reason, that mechanism could get triggered again. You can literally fall in love again.

Women like signs of money and education - things that indicate that not only is this guy going to have some resources, but he's also willing to share them.

There is more and more data indicating that there is a biological basis to your political views.

When you look at the brain regions associated with picking up data from the body, a huge amount of the brain is devoted to picking up information from the lips and tongue.

A lot of people have been romantically in love with somebody who they feel wasn't appropriate to marry.

Women apparently are quite drawn to men who have differences rather than similarities in their histocompatibility system. They pick it up by smell, and they can pick it up from kissing.

Romantic love is an obsession. It possesses you. You lose your sense of self. You can’t stop thinking about another human being.
