Yawn
Yawns evryone does it. So why do people yawn? Well theres two reasons for that: one it being contagious or it being a sign of a seizure. Or even just that person being to lazy or tired. But in research people have found that people find yawning contagious.Reasearchers found that yawning is contagious from ancestors that used it to signal others something and or to maintain group individualism and got passed on through generations and was very contagious to them.This article was very interesting and informative to many people. To me it told me alot of things about yawning I didnt know so this helped and answered my question.
