I think romantic love evolved to enable you to focus your mating energy on just one individual at a time, thereby conserving mating time and energy.

We're apt to fall in love with those who are mysterious and challenging to us.

You can get into a very fancy car and know everything about the engine, but when you drive in that car, you feel that rush. In the same way, I think the more you know about love, the more you can enjoy it. And knowing about your personality type, who you are and what kind of person you're dealing with gives you a great leg up.

Any kind of novelty or excitement drives up dopamine in the brain, and dopamine is associated with romantic love.

People kill for love. They die for love.

People have been looking for love potions since hunter-gatherer societies.

Romantic love allows you to focus mating energy. Attachment sustains that relationship as long as necessary to raise your baby.

There's every reason to think SSRIs blunt your ability to fall and stay in love.

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.

When you're in the throes of this romantic love, it's overwhelming - you're out of control, you're irrational, you're going to the gym at 6 A.M. every day - Why? Because she's there.

In that early-love stage, you're in that state of exhilaration. You talk till dawn. You become obsessed with 'What does he think?' 'Does he like me?' 'Does he think I'm fat?'

In America, we are demanding everything from our marriage.
