While I do think those are the key quotes of the article, I'm not sure I'd call those interesting. Those quotes belie the truth--the article and any inferred

  Not completely meaningless, in that it might point to a direction for further research. There is certainly nothing actionable here though.

    Further research is actionable. This is useful encouragement, because absence of correlation implies absence of causation, so this is an efficient way of eliminating one disproof early.

  When the conclusion is, literally, that there is correlation between these two variables over which people have control, how can you say it's "meaningless"? It's some evidence of what seems like an obvious hypothesis: sleep is healthy and exercise is healthy; if you do more of one and less of the other it should even out in some manner. They looked at the data and saw that this appears to be the case. The "correlation is not causation" crowd who show up in every scientific article being discussed is the worst kind of pseudo-intellectualism. The authors of the paper went out of their way to say it.

    > The authors of the paper went out of their way to say it. 2/3rds of the way through. I'm glad myself and others point this out. I personally read the whole article. That's time I can't get back. In the interest of keeping HN content worthwhile, people can and should point this sort of thing out. Plus, the title isn't exercise and sleep correlate with health. The title implies causation.
