The Science of Kissing

Tomorrow is Valentine’s Day so this is a good time to take a look at the science of kissing. The following video from It’s Okay To Be Smart (produced by PBS Digital Studios) explains why humans kiss, the history of symbols associated with kissing, and some cultural views of kissing. When I saw this video I immediately thought of my friend Jeni who teaches high school health.

H/T to Brain Pickings.
