For some reason, I've always imagined that "nerd-type" people would have less ability-to-react than the general population. Maybe it's partly the stereotype of the awkward geek, or the fact that programmers, in particular, spend long periods of time alone without social interaction to impose thought-deadlines. But this population also (stereotypically) plays a lot of online multiplayer games. I wonder if playing games like World of Warcraft could lead to transferable skills, like better awareness/awakeness to immediate events.
