Because people are too stupid to notice that it lets in more air in your body when you don't have enough
We yawn because when we breath through our mouths it brings in more oxygen than when we breath in through our noses. ( which is what most people do.) Sometimes, our brain doesn't think that its getting enough oxgen so it makes you yawn. Try yawning now - feel how much oxgen comes into your mouth? That's why.

they yawn because when you yawn it passes on to other people . so you yawn then someone's right next to you then i think they inhale then they start to yawn ?
