Wow, I just yawned too!
This is amazing. I can only imagine how many people you just made yawn.
I guess that the thought of sleeping alone is enough to make you sleepy. I have no idea. You should base some kind of research project off of this. Make it a survey.

people yawn because of lack of oxygen to the brain but when people do simply after seeing someone else does it , i think because the chemicals in the brain and sensors remind the person to yawn; just a guess

as a very outdated body signal to express dominance. it bears the teeth. this is why others tend to follow suit.

Because you didn't get enough restful sleep like they didn't.
