Such a sensationalist link-bait title.<p>1) Correlation is not causation.<p>2) The study is between two groups: those who watch TV for > 6 hours a day (!) and those who don't. Who in their right mind watches an average of 6 hours of TV a day?
Another "sitting is death" article but with a more sensational title.<p>Remember they found that even activity doesn't reverse the sitting-death, you just cannot sit, period.<p>Personally I'll take the year or two penalty.
