In analog life, an adult laughs about 15 times a day. But if we could read all their virtual interactions, we would think we were looking at a clown, a maniac or a child.

The face that cries with laughter is the most used emoticon on Apple, on Facebook, even on X. Laughter is 30 times more likely to occur in the company of other people than when people talk with friends, says Michael Brecht, from the University of Humboldt in Berlin.
