 I think what you're saying is that two hours after the fight is over, the body has stopped sending you signals that a terrible fight has happened. The body has gone back to baseline. But the story of the fight, the map of the fight, continues in our heads. And for some people, that map becomes so powerful that the fight now persists. And now it has a life that basically is lasting a week, a year, a decade, when the bodily sensations of that fight, in fact, have dissipated in a couple of hours.
