Why do we fall in love with one person and not another? Is there such a thing as love at first sight? Today’s Please Explain is all about love and attraction! Dr. Helen Fisher, author, biological anthropologist and chief scientific advisor to Match.com, joins us to discuss romance, dating, and marriage. We'll be taking calls from listeners with questions about love.
