i come to realize that when a person next to me started to yawn,, a few seconds later i started to yawn also?? is this really a contagious thing? or just a psychological effect of thinking that when somebody yawns, its automatic that you will do it also unconsciously?

I think that yawning is contagious and the reason it is,is because when you yawn it does not mean you are tired,it just means your brain is not getting enough oxygen,so I think when you see someone else yawn,it makes you yawn,so that way you will get more oxygen going to your brain,and that is why some people yawn a lot,and some people hardly ever yawn.
