I wonder if this ability is just a function of increased adrenaline in the system or the sudden increase of adrenaline. If it is, it would be easy to make a switch, but would probably be harmful for extended periods of time.
If I understand this correctly, the immediate fight-or-flight response is triggered by noradrenaline, which is very similar to adrenaline but released by nerve cells directly to places all over the body, increasing blood flow and pressure, alertness, etc (but not affecting muscles). Adrenaline gets released into the blood via stimulation by the sympathetic system, but its effects last longer.
So it seems noradrenaline, by the fact that it's released directly from nerve cells, basically dictates how fast a person processes immediate external stimuli, and could possibly explain "super perception"
