“…In your opinion do you think most people have enough acetylcholine in their systems? Yeah actually I think the tendency with aging is to have too much. The shock reaction is for over a hundred years now there's been evidence that over activity of the vagus nerve and the parasympathetic nerve system produces shock. That it's the essential factor in shock. And this is the system that acts primarily through acetylcholine producing nitric oxide. Nitric oxide blocks oxygen metabolism. So in shock your blood stays red and full of oxygen but the tissue can't use it.”
