I agree with the comment's above, you do lose out A lot on life playing games like Second Life etc... so many things can destroy you playing those sort of games. Specially for young people has they grow up not focusing on school there future because stuff like that will become A habit which develops A hole, the more you play, the more chance you life is going down it's A serious habit. Even on the X-box and PS3 getting really addicting to playing a COD or Halo etc.... Playing that all day instead of going out and communicating with others getting some exercise and fresh air. It's really unhealthy for your and really bad for your future, it's ok to play games now and then in your spare time. Even most unemployed adults over the age of 18+ still doing stuff like that and living with there parents because they never focused on school and his future and just stuck in another world and not even getting a job. But anyone should think more about there future more than games. Games can wait and be played anytime, but Time doesn't.
