Thanks! I didn't want to register to read that article but what I could glean from the abstract was what I already understood... that amphetamines are used to keep men awake and moving.
People use phrases like "super human strength" when what they actually are talking about is someone so drugged that they do not feel pain and they have an enormous amount of adrenaline pumping.
Not feeling pain enables a person to do things that a sober person could do with protective equipment. It doesn't give them a 10 foot vertical leap, or an ability to break handcuff chains.
She did not go down from the pain of the taser because the drugs she was on set the pain aside.
My understanding of how a taser works is it interrupts electrical signals from the brain which control muscle movement. The properly tased person just drops to the ground and twitches.
A person not responding to being tased automatically raises the question of whether they had been properly tased... two darts from a fully functional device firmly embedded in tissue.
You ignored the "adrenaline pumping" part of it.
Your body is designed to allow you to do amazing things in order to live.
And yes if you can not feel the pain you can break at least some handcuff chains. You stop pulling because you are tired and it hurts. If you are not feeling the pain or the weariness you can keep going until your bones break. And your bones are incredibly strong.
