A scene from “What I Did For Love”

Meredith (voice over): Here's a partial list of chemicals that our bodies produce when we're falling in love. P.E.A. is a natural form of amphetamine. It puts us on high alert. Pheromones, produced from DHEA, create an inexplicable sense of well-being and comfort. Oxytocin has been called "the cuddle hormone", and it stimulates the secretin of dopamine, estrogen, and LHRH. This cascade of feel-good hormones and neurotransmitters is also generally accompanied by poor judgment. No wonder they call it "crazy in love".
