"Every single hour of television watched after the age of 25 reduces the viewer’s life expectancy by 21.8 minutes. By comparison, smoking a single cigarette reduces life expectancy by about 11 minutes, the authors said."
But if sitting and watching TV brings greater satisfaction than walking around does, what's the point? It doesn't seem like anyone's claiming that the purpose of life (not that there is one, other than acquiring antique jewelry) is to simply live as long as you can, although I guess there's not really a more-useful, equally semi-quantifiable barometer. Deep thoughts. Walking cigarette break.
