    > no conclusions should be drawn from a single study period

I didn't see the point in pointing out the obvious - I thought that's as annoying as on reddit's /r/science the inevitable single-sentence comment "correlation is not causation" for no reason whatsoever (i.e. when nobody made that claim). I pointed out the age threshold because there was a comment (of only 6 or 7 total at that point) that attempted to draw the conclusion that older people are doing worse.
