Honestly, I feel like a study of this nature is backing up what we already know to a degree.

But, we need to know more and I feel like a 4 year tracking period isn't enough. For example, how do we know that people who were already the most unhealthy coming into this study are also the most sedentary? How are they handling these types of things.

That's the danger of these types of studies. We all know what is healthy and what isn't, but the methodology here is suspect at best and the analysis shows weak conclusions. When headlines like the one posted here take root and people expose the truth for what it is, it damages the credibility of research and science in the minds of the masses, who are then more likely to ignore science in general.
