I am not going to tell where I am living, but I was born into a hell hole. As a kid, I used to give myself this right: If you attack me, I give myself the right to do what ever I see fit and can get away with. Otherwise, I was very nice and peaceful. I read philosophy, warfare at age 11 and led big street battles at age 14.
Since I pretty much grew up from the street, my learning rate has been very high. At this moment I am well versed in pretty all known subjects for mankind, ranging from Computers, Electronics, Advanced Physics, History, Philosophy, Economics, Law, Martial Arts and so on.
You know, when I watch the Western movies when the cowboys grab each other shirts to punch, I always lol. My punch is so fast, I rely on the opponent's body inertia mass to hold his body in place. My punch just simply penetrate the intended target and destroy the soft internal organs.
Do this experiment. Put a piece of paper underneath a glass of water. Slowly pull the paper or quickly snap the paper out to see the effect of inertia mass.
