The Yawn-o-meter - How long does it take you to yawn?

I think there is something wrong with me. I watched this and didn't yawn... However, my husband yawns whenever I saw the word yawn.

Give this video a watch and let me know how long it take you to yawn. *At the end of each month, I will award one random commenter from the month an eBook of their choice (my books, of course.) So be sure to leave your email. :)
