Everything you wanted to know about Kissing – whether you want to or not. *smile* Including theories on the origin of kissing (mothers passing chewed food to their baby similar to birds?), what about cultures that don’t have kissing (or do they and they don’t talk about it), the effects of kissing including who, what, and why we kiss, the history of kissing (as far as they can tell) and the anatomy of kissing (oxytocin, dopamine, adrenaline, serotonin – no wonder we enjoy kissing!).
