I think it's really interesting to see so many people here jumping up to defend gaming. Nobody is blaming games or gaming, the original post simply states that like everything else, you should make sure that you moderate the amount of gaming you do and also try to do things that are good for your body. I think it's a good message for Hacker News given the number of gamers we have here (I can easily log 20-30 hours a week when I have a new game and some free time). If you game a lot but you don't let it get in the way of your health then this message wasn't intended for you (except perhaps as a cautionary tale).
