The work looks useful and valuable to this area of study. But WaPo and other media outlets persist in a ubiquitous and terrible trend in science reporting, especially those associated with lifestyle and healt : "Here is a study which has different findings than the other studies we've been reporting on, all that research is now overturned! Burn your standing desk!" Of course, in a few months, someone will publish another study calling this one into question, and they'll tell us all to go out and buy new standing desks. As we all know, science doesn't work that way. This study needs to be put into context with other studies, if it contradicts those studies, that needs to be discussed, future studies that might resolve the discrepancy should be identified, limitations on the applicability of this study and on the ones it contradicts should be pointed out, changes in the model we use to understand the effects of mobility and posture on health should be discussed, etc. etc.
Instead, we get serial repetitions of "standing is bad", "standing is good", "it doesn't really matter". I have to look at a calendar to figure out if the caffeine in my coffee is slowly killing me or turning me into a focused super-intellect. Won't someone please, please tell me if I should be ingesting wine and/or chocolate this week?
