What I said was you FEEL the adrenaline RUSH once the immediate crisis ends.
I reckon everyone is different. I feel it all the way through: My surroundings moving in slow motion, feeling like I am moving through water, with the ability to think about how best to grab something moving through the air (or not) before it gets to me or which way to get out of the way or best absorb or deflect the impact, hard to describe, but thinking is crystal clear,
fast, analytical, and even, on occasion, humorous.
But yeah, the rush was on long before the action stopped in each instance. Or maybe ours is a problem of definition and you don't consider the performance enhancement aspects part of the 'rush'. I do.
Aftereffects (leftovers) were at times like having a few too many espressos, but those were the leftovers if the situation was resolved before the adrenaline burned off, and yeah, I felt that, too on more than one occasion.
