Earlier today my dad went in for requalification on his gun card and I decided to tag along. For the most part, I just stood silently observing my surroundings until we passed through the training room where I noticed a punching bag hanging in the middle of the room.
I have no martial arts training and even less experience, but I had plenty of pent up aggression (anyone who's read my first blog post knows what I think of "getting it out in the games"). While my dad was using the restroom, I took the time I had to take a few swings on the punching bag. After my little session I walked away with a rather nasty bruise on my right hand. Next time I get a chance, I'll take the rangemaster's advice about using the knuckles on my index and middle finger.
I realized something from this about venting aggression: actual physical exertion works much better than playing a video game (no matter how violent it is). So, my advice to people that say "Get it out in the games" is to try hitting a punching bag. It's much more gratifying and it won't make you obese.
