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.

Romantic love is one of the most addictive substances on Earth.

Barriers tend to intensify romance. It's called the 'Romeo and Juliet effect.' I call it 'frustration attraction.'

Scientists know that women gravitate to men who have a different immune system from theirs.

Anthropologists have found evidence of romantic love in 170 societies. They've never found a society that did not have it.

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

Experiences shape the brain, but the brain shapes the way we view experiences, too.
