Hi mate, Check out this amazing post ... After reading i just felt not yawning for days.. http://weirdstuffandnews.blogspot.com/2007/11/that-big-yawn-can-kill-you.html Mike
I want to yawn right now, but after reading this... I will try to open my mouth as small as possible.
Hey mate its easy to say "why do i keep yawning after reading this" but do feel the pain the person would be in at those circumstances Mike
