endorphins only last for a few minutes, and shock is more or less you have 0 comprehension on whats going on, unless your a manitee.
I cut 1 finger off with a hedgetrimmer, that severed it in like 20 places, not fun. endorphins kicked in right away, Shock only lasted 10 minutes, addrenaline ruled out the endorphines, and then I started flippin out.
Then 2 years ago, I cut another finger off, trying to tap a fuel line in MY EFFING CAR!@@@@!!!!! yea, Drill > finger.
But the shock depends on the type of injury, a gun shot wound is different, addrenaline is upped, and so is the bodys own pain killer chemical, but sometimes the body fights each chemical = Addrenaline > endorphins. Addrenaline will over rule endorphins, and if you dont go into a cold shock, you will feel it. This is why some torture victims are fed epinephrin or large ammounts of spike energy drinks. Mix this with certain amino acids, Bradykinin Enzymes you will show somebody enough pain to spill any ammount of beans, and s**t themselves instantly.
Yea, shock is a beautiful thing, along with endorphins, but feel bad for the people who's endorphins are offset by another chemical, naturally.
