People have been sitting at desk jobs for over 100 years now and those people at an old age are living longer than anyone in history based on life expectancy. Isn't this one of those standard logic fallacies? I mean, A is true, B is true, but that does not mean B is true because A is true? There might be plenty of other factors affecting B. The advance in medical science for one. At least I always thought that alone was the most influencial factor on better life expectancy. Probably more than enough to even undo the effect of certain lifestyle habits making things worse. But yes, the article pretty much fails to provide exact numbers or even estimates on how bad a sedentary lifestyle really is.
