TV, computers, and video games have long been my prime suspects. I know the ability to multitask has also increased my propensity to do so. Hey, I'll just pop over here and see if I have new mail. Oh hey, I've been wondering about X for a while, I'll quickly Google that. Hmm...What's the weather going to be like tomorrow.

Oh right... I was working on something.

As for the symptoms being advantageous, I think there's something to that. I thrive in high stress, high demand environments. When I'm doing event support, there's nothing to do but run from crisis to crisis. It's messed up, but it keeps me excited and engaged. It's like a hunting dog who wants nothing more than to be out in the field digging through brush and rusty fences tracking game.

But there are only so many jobs that can scratch that itch.
