This week's professional study concluding the obvious:
CHICAGO (Reuters) - U.S. youths who watch television on weekdays tend to do worse in school than those who don't watch during the week, but weekend viewing appears to have no negative effects on schoolwork, researchers said on Monday.
The study of 4,508 middle school students ranging in age from 9 to 15 years also found schoolwork suffered among those allowed to watch adult, or R-rated, movies and cable channels with adult programming.
I guess I shouldn't make too much fun of the study, since it did provide the solution to the problem we've all been waiting for: Parents should limit their children's weeknight TV viewing! They should probably ask about their children's homework, too, but let's wait and see what the next study says.
