DID YOU EVER FIND THAT YAWN IS A CHAIN REACTION?

Today morning when i woke up i was thinking of why do people yawn when we see other yawn.So i made a little search on found some info.Generally so many people think that yawn comes when they are bored but it is not true it is also just a theory.But none of the scientists proved that why people yawn it is just not proved yet.I am not kidding.Just try it out when you are in class or in auditorium.Yawning feels so good.I was reading an article on yawning i controlled myself not to yawn but i couldn't control at all.So when you see other yawn they try to stop yourself from yawning.The funny thing is that even i was yawning when i was blogging this.
