This isn't revolutionary. But it's a perfect example.
This is a completely derivative conclusion from something I learned in molecular biology as an undergrad. The only "new" thing here is saying that poor people live in environments, since we've known for literally decades that DNA methylation is affected by environment.
> a person's perception of whether they "are" rural is actually a better predictor of their health outcomes than whether they actually are rural.
OK. Great. I'm poor if I think I'm poor. Roger.
> These are both potentially useful things to know as we try to eliminate extreme health disparities between Americans. You seem to think we have all the answers though, so what's the answer? How do we do it?
I don't know! You tell me how your "potentially useful" information provides a solution. Win me over!
