AUDIO TRANSCRIPT

Dr. Helen Fisher has performed extensive research on the brains of people who have fallen madly in love to understand how romantic love is not just an emotion but a drive, hardwired into our brains.  These findings, along with cultural contextualizing and other analysis are published in Dr. Fisher's new book, "Why We Love, The nature and chemistry of romantic love."
