>the people weren’t necessarily healthy, just alive. Well, yes, when you do a study based on mortality you get a result based on mortality rate. For all we know all the other studies mentioned in the article were also based on mortality. The article was being a bit dishonest by implying that mortality rate is a bad metric without addressing the issue of why that might be so in this case. The actual point is, as you point out, that sitting is bad. The headline is still wrong and pointlessly so.
