Love and chemicals, chemicals and love. Or Damn all this love inundation!

Fabulous excerpts from this month's National geographic Article, "This Thing Called Love."

"A woman unconsciously uses orgasms as a way of deciding whether or not a man is good for her."

"Love and obsessive-compulsive disorder could have a similar chemical profile. Translation: Love and mental illness may be difficult to tell apart. Translation: Don't be a fool. Stay away."

"According to this theory, we love whom we love not so much because of the future we hope to build but because of the past we hope to reclaim"

"Helen Fisher has suggested that relationships frequently break up after four years because that's how long it takes to raise a child through infancy."

"If the chemically altered state induced by romantic love is akin to mental illness or a drug-induced euphoria, exposing yourself for too long could result in psychological damage."

"Assuming a fairly healthy relationship, if you have enough orgasms with your partner, you may become attached to him or her. You will stimulate oxytocin."

"And I knew it wouldn't last, couldn't last, and so that infused it with a sweet sense of longing, almost as though we were watching the end approach while we were discovering each other"
