During these few seconds, you are able to move ahead fueled solely on adrenaline and anger. I once saw a friend who after getting kicked in the nuts, chased his attacker for 3 blocks before finally falling to the ground. I have experienced this. I was 16. Long before I had found this discarded basic bow that lacked a string. I used it as a means of exercise from time to time where I placed one end on the floor and pushed down on the other end and got a decent tricep burn bending said bow against the floor. Well, one day, the end touching the floot slipped. The end in my hand came loose and smacked me in the jewels. I stood there with no pain for a minute thinking that it was a close call. Then BBLLAMMOO I hit the floor all curled up into the fetal positions unable to even wimper for a couple of minutes. I think this is Evolution's way of saying that if you strike me to the life makers I have time to exact revenge for your effontery before the pain hits.
