I added to my original post but since I did that I have become exceedingly more freaked out about that stupid sheet of latex they supposedly use. I watched some youtube videos of it. I don't understand how you can breathe!? It covers the ENTIRE mouth! Why, why why?! I am a fan of oxygen, please don't deprive me of that, too! Isn't complete power over me enough? Why take away the ability to freely get a breath of air?! Is that supposed to make people more compliant or what? I can't stand a sheet over my face how am I supposed to get through hours with my mouth covered? Is it so you can't speak or say anything?! My dental hygienist got on to me for holding my breath when she was cleaning my teeth, but these people make you do it?! What do they get out of shoving that thing down in your mouth?! The balance of power is already completely in their favor, why this too?! And what about that clamp thing it is held on with!? That thing looks evil!
