Yawning is a proccess in which you exhale carbon dioxcide through your mouth after inhaling oxygen. There is a saying that if one person in a room of 3 or more people it can spread making everyone yawn after another until it goes back to the one person who started it. But how does it spread? Well I'm not sure how it spreads but I know it spreads. I GOT EVIDENCE!! Last night when my mom, dad and I were returning from our dinner, my mom began to yawn and then I yawned and then my mom yawned and my dad yawned and I yawned and so on. We were randomly yawning after another but it was spreading through the air!!
