2. Kissing takes serious muscle power.
One kiss requires 146 muscles to coordinate, including 34 facial muscles and 112 postural muscles. A team of British researchers: Elaine Sassoon, Annabelle Dytham, Robert Scully and Prof Gus McGrouther from the Rayne Institute in University College, London, studied kissing couples under an MRI scanner and found that a kiss mostly involves the orbicularis oris (the muscle around your mouth).
“Not only do you use your facial muscles in kissing, but approximately 112 postural muscles as well,” Professor McGrouther said to The Telegraph. Yikes, sounds like a serious facial workout!
