do you yawn when you see people yawning?

This is a pretty good discussion because I know people always say that yawning is contagious and when one person yawns everyone else seems to yawn as well,but I have heard that yawning has nothing to do with being tired,when you yawn it means your brain is not getting enough oxygen,which sounds pretty weird,but I guess when you yawn it helps your brain get more oxygen or something,and I am not sure why it is contagious unless if one person yawns,another will also need more oxygen for their brain so they will yawn as well,and I know that whenever I see someone else yawn I am always yawning,and it often ends up in a yawning train,like the other day me,my fiance,my mother,and my father were coming home from eating,my father yawned,then my fiance yawned,and then I yawned,and then me and my fiance kept yawning,and my mother was like stop yawning,I am not sure why she did not yawn because she was the only one who was not yawning,and she is usually the only one yawning lol,and she is usually the one who has been up the longest,so she has more of a right to yawn then the rest of us do,have a great day,good luck with your life,and all of your mylotting goals,and Happy Posting.

Now its a surprise. Not only seeing a person nearby yawning causes you to yawn, now its late night already and your talk of yawning led me to yawn and I feel like to sleep now. It seems as if this virus is more powerful than swine flu virus, its getting transmitted even through the monitor...What a deadly virus... I am sleepy now ...Good night...

This is an interesting topic. Yes, I yawn when people next to me is yawning. I don't know why, but I think this is funny. Maybe is an epidemic...LOL

yes I do... and I've always wondered why do people do that after another person has yawned. i wonder why that is? hehe it's puzzled me throughout my whole lifetime. :@)
