There's only one cause of PTSD: The fear that comes with your certain belief that you are going to be killed immediately.

This much cortisone to the brain stem generates near permanent changes to the wiring of the brain.

Nobody should mock the origin or effect this has on the individual. When you see the fear in their eyes, you know.

A PTSD vet cannot travel without a weapon. They cannot sleep without a weapon within reach. They check all the doors and windows twice every night.

And, if you ever want to be around somebody who's ready for imminent battle to the death, every moment of every day, look up a PTSD vet.

It's not just about flashbacks. It's about a nervous system locked into "flight or fight" mode continuously.

I will state that that is Horse Sh#t. I grew up with fifty or guys all served in Viet Nam mostly in the Infantry in every major battle in the war..

All of us came back from there and after a period of readjustment are now married and retired to Florida, except me I retired to NH.
