12 years ago, my 2nd book, The Science of Kissing (Hachette, 2011) came out. It’s about the neuroscience, biology, evolution, history, real chemistry & potential future of connection.
With #ValentinesDay around the corner, would fellow #science & #culture nerds on #Mastodon be interested in a few facts & stories from the book?
A Science of Kissing thread it is! I’ll add to this until Valentines Day:
1) Lips are the body’s most exposed erogenous zone. Unlike in other animals, human lips are uniquely everted, meaning they purse outwardly.
Kissing is about more than romance or bacterial exchange. Our 1st experiences with love, security & closeness often involve lip pressure & stimulation through nursing or bottle feeding. This lays down neural pathways in a baby’s brain that associate kissing with positive emotions.
Has there been research on possible differences in which people enjoy kissing, having been either breast-fed or bottle-fed?
