Hm.

Everyone's risk of death is in fact 100%
It's the quality of the journey that matters, and that is not necessarily directly related to its length.

@bibliolater @science Remember - correlation^= causation. That's especially true for studies like this were there's a good chance of reverse causation - that is, people with worse health not being able to walk as much.

@meredithw @bibliolater @science Good point, as a medical layperson I would have not thought of that. Since the causal interpretation seems mechanistically plausible, it is tempting. I have yet to read the full paper but its abstract and conclusion are more carefully phrased than the reporting about the paper. I wonder if one can factor out negative correlation somehow in study design or analysis.
