By Sheril Kirshenbaum
Hardcover, 247 pages ($19.99)
You must remember this: A kiss is just a kiss. But that well-known song lyric greatly oversimplifies the emotional, social, biological and cultural implications of this ancient, universal gesture—the most romantic behavior in human history. The author, a science writer and researcher at the University of Texas/Austin, examines the smooch inside and out in this sweeping, solidly entertaining and delightfully enlightening overview, appropriately subtitled “What Our Lips Are Telling Us.” Pucker up and get ready to learn something!
