Research scientist and science writer Sheril Kirshenbaum will discuss and sign copies of her new book, The Science of Kissing: What Our Lips Are Telling Us.  Psychologists report that most people can recall up to 90 percent of the details of our first romantic kiss, and that memory makes a stronger impression than even our first sexual encounter.  This book brings together classical history, evolutionary biology, psychology, popular culture, and Kirshenbaum’s own scientific research to present a comprehensive look at the most romantic act in human history.
