A Rigid, Sterile Look at Kissing

Josh and Chuck dive into the surprisingly complex world of kissing, exploring whether this universal human behavior is learned or instinctual. They examine fascinating theories about kissing's origins - from ancient mother-to-child feeding practices to cultural diffusion via Alexander the Great - while breaking down the science behind what happens to your brain and body during a kiss. The hosts also cover the muscles involved, the role of pheromones in attraction, and even touch on some of the less romantic aspects like diseases that can be transmitted through smooching.
