So, I've noticed that a lot of nerds participate in martial arts. This is not at all to say that martial arts is inherently "nerdy" more than it is saying that Star Wars is inherently nerdy. Both of these things just happen to call out to the socially alienated among us. But, here's my point. Let's say there's a guy, 5 ft. 6, 165 pds, black belt in several martial arts. Could this guy beat up Brian Urlacher, middle linebacker for the Chicago Bears? This karate-man knows exactly where to punch and exactly where to block. But, couldn't Urlacher just rush him and kill him with one blow? My real point is...should I be scared of the IT guys at my workplace?
