I have often wondered why people would attribute this and other events where one has super human strength or super perception (where time slows down) to adrenaline. This is becasue it is a hormone that is released from the adrenal gland..it would take some time to get to the parts of the body where it would make things function this way would it not..at least longer than the times we are considering would allow. So if I am right, what else could be the "switch" to switch these functions on?
