Not only does it keep the young in you, I think it's great stimulation for the brain and reflexes. Most people who are anti-game are simply afraid that they are no good, or that they don't know how to play.
A friend of mine was talking about how she hates airports on her blog and I mentioned that the ticket is to overwhelm yourself with things to do like work, iPod movies, magazines, etc. I mentioned that I take my Nintendo DS and play that in the airport (and on the plane) and she seemed mortified that I would do that in public. I guess I really don't care what people think ultimately because I'm still going to do it. Out of curiousity, though, since I am apparently socially clueless, I ask you, fellow geeks, is this odd?
