I have had some interesting experinces, while young and not on drugs, and older and not on drugs, that may suggest that i could have some traits of a "3%'r. The oft mentioned kick, knee strike to the groin makes me mad, even if after it happens to do damage. Have gotten the deadly throat strike, that is supposed to kill someone, that made me not able to talk for 20 minutes. Worked for and waited to see a Dr. for about 6 hrs after breaking my back, but the fact that I was in decent shape, made it so it was a stable break. Just wondered how to actually tell if you were or weren't, or are there people who are born this way, or grow into it, or if chemicals induce it.
PS I am wondering if you can just "train" yourself into it. We used to just play very rough as kids. Tackle football with no pads, at full speed, a game clled "chicken" where a kid rode on you "piggyback", and you had around 5 to twenty teams. The object of the game was to crash in to each other, and make the person who was on piggyback, touch the ground, and the team was out, and the last team standing won. We also played a gmae with a football. where the person with the ball was chased, and tackled, or whatever, the object was to obtain the ball. There was no winner, the game went on for a long time. We also played "ice bowl" versions of each game in the winter. It always seemed to rain with a layer of snow on the ground, we always managed to get a rogh game of some sort started. Fights, were not looked down upon like they are today, it was just something that happened.
