This photo documents something anyone can notice: While we’re sitting, we touch our mouths a lot.

The photo shows the full faces of 22 men; 7 of them are touching their mouths. I have noticed something similar at many faculty meetings. I started to notice this after I read about its observation in a study designed to measure something else.

I’ve known about this for many years but have never read an explanation. Do we enjoy touching our mouths — or is the absence of touch for a long time unpleasant? If so, why?
