Maybe I'm doing something right... according to Wired, "distracting your brain" can actually improve your mind's performance (note: I'm not taking a stand on whether your mind is your brain - though I'm not sure where else it's supposed to be).
Before anyone gets too excited, the distraction needs to be related to what the brain is supposed to be processing. This seems to indicate that it's better to distract yourself with something like a blog... about philosophy... than say the undergrads working beside you at the coffee shop talking about how they're going to start their paper due on Friday after they go out Thursday night..
Oh and a little caffeine may help you not get Alzheimer's... maybe.
