When i yawn saliva comes out thrushing like what a snake does when spitting poisen, why ?

Thanks, Dr. M: Thank you dr. Mcnay. I am learning something every day. Although I have seen that happen when patients open their mouths on occasion, i didn't know about gleeking, also known as docking. I wonder what the guinness record is. Something to think about to become famous.

Your Gift: I will say i find it pretty fascinating myself but your muscles under the saliva glands squeeze them so perfectly and your ducts are so perfectly aimed that you gleak. It's a rare gift that has to be guarded, so have your hand handy each time you feel the yawn coming. :).
