The Saber to Tiger Effect

The parasympathetic controls that high activation. So it's a TSD, if a veteran hears a horn go off and they're all of a sudden back in a war zone ready to face combat. It doesn't matter that that was a car horn. It still feels like a life and death threat. And so that's the dropping all the way down. The saber to tiger actually has you. And there's really no way out. Or maybe you have used that to defense at some point in your life.
