Some of us are. All of us have the makings of real medical disasters brewing inside us. After liberation, we cannot remember the horrors of this nightmare. It doesn't come back. It never actually existed, since it's history, and impossible to retrieve.
Nobody there wants to go back to that.
They got it. They get it. We're getting it now, we're them, inside the nightmare still, but very close to the edge. What I'm writing here is very conslusive. It is hard to argue with it because it is so large as to encompass eternal time.
