While composing The Science of Kissing, I sifted through every source imaginable on the subject. I read papers on anthropology and dentistry, spoke to neuroscientists and classicists, and scanned many pop culture references as well. It’s been fascinating and fun, but one peculiar ‘trivia fact‘ I kept coming across bothered me:
‘Kissing for one minute burns 26 calories.’
Preposterous of course, but I couldn’t help wonder why ‘26′ was popping up everywhere. It seemed so random. Obviously this is not in the book, but I was increasingly curious as to how and where the rumor got started.
And then I finally solved the mystery!
