are yawns contagious?

I don't need to see to catch it "live" to catch it. Watching it on movie or hearing it will trigger me to yawn as well. Yawning is definitely the most contagious disease in the world.

The yawning only bothers me if I am up past bedtime and I have to try to stay awake, you know like being at work. Sometimes a person just can't help but keep yawning once they see another doing so.

I am not sure but if I see someone yawn I tend to yawn myself.

That does tend to happen a lot of the time with me. Along with pretty much everyone else around me. I know that people have gotten on me for yawning, because it makes them yawn. It is really does in fact cause a chain reaction. One person yawns and that causes some kind of mental trigger in the mind of a person, which causes them to yawn. It is very strange all things considered. However, when other people yawn, it makes me yawn. I could have slept for months and months but if that will still happen. I could be the most well rested person in the world, but still, yawning is something that still happens all of the time. It does seem like a group activity. Once one person yawns, everyone yawns and it really just steamrolls from there.

Yes, I think it is because every time I see someone yawning I also start to yawn. It always happens and sometimes I hate it because it's embarrassing especially in public places like restaurants and in parties and gatherings. Does anybody know what to do to prevent this? :)

This thread topic reminds me of a time I was with two co-workers. One of my co-workers and I were listening to the other co-worker, and also close friend. Anywho, it was funny, because the one who was talking wouldn't yawn at all, but the co-worker listening would yawn, and than I would follow immediately after. It was amusing because we just kept going back and forth for a good 10 to 15 minutes or so. I find it hard NOT to yawn when I see someone else doing it. A natural reaction for me I suppose. Very rarely can people fight it.
