I'm not sure if that applies here.  Most people "waste" a certain amount of their week on downtime, and that's probably healthy for them.  Whereas in ages past that was checkers at the general store or a bard's stories at dinner or listening to the radio, today it's TV and video games.  A person who watches 40 hours of TV a week for fun is in just as much trouble as a guy who plays WoW or EVE for 40 hours a week.
