Until recently, we regarded love as supernatural. We were willing to study the brain chemistry of fear and depression and anger but not love.

The main characteristics of romantic love are craving: an intense craving to be with a particular person, not just sexually, but emotionally.

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

Haiti is the poorest country in the western hemisphere; some say the poorest in the world.

Games are the way we keep romance alive. They're based in human hardwiring. Playing hard-to-get or leaving a little to the imagination allows the woman to be wooed and appreciated and the man to be challenged and intrigued.

There's all kinds of reasons that you fall in love with one person rather than another: Timing is important. Proximity is important. Mystery is important. You fall in love with somebody who's somewhat mysterious, in part because mystery elevates dopamine in the brain, probably pushes you over that threshold to fall in love.

There's a lot of talk about the positive aspects of love. We as a society downplay the danger, the anxiety, and the disappointment. We romanticize romance.
