Yea me too... I am about as laid back as can be and last weekend (2 weeks into it) a guy was running his mouth like really loud to a buddy of mine and my face and arms started getting really really really hot! Well he put his hand on his chest and kinda pushed, well my leg started shaking and I looked away and next thing I know my hand passed my face and knocked the dude on his fucking ass. I hate confrontations, but the situation exploded before I was even ready lol.
So I'm on the same aggression mode your on. The aggression in the gym has been nice too though!!
