>WHY WE LOVE

To paraphrase Elizabeth Barrett Browning: How do I love thee... and why? For her book Why We Love: The Nature and Chemistry of Romantic Love, anthropologist Helen Fisher, 58, studied the brain scans of people in love.

LIGHT MY FIRE When someone looks at a picture of their beloved, regions of the brain associated with its desire to win rewards light up.

POWER OF LOVE People feel incredible energy when in love, probably because of increased dopamine [a feel-good chemical] in the brain.

FAST LOVE Men tend to fall in love faster than women.

LOVE IS THE DRUG My advice is to not sleep with [a new person] right away because when you have sex, it drives up the level of oxytocin, a hormone believed to be associated with love, and that causes attachment. Be on guard at the spa as well: Massage drives up levels of oxytocin.
