I saw this article, can't remember where first, about poverty and psychology, about various kinds of decision-making and persistence as finite resources. And not only is it interesting in that context, but it made me wonder extremely about chronic illness and chronic pain problems and how they might also affect control/persistence. A lot of chronic health problems could be described as creating a dearth of energy or other bodily resources in a way that might be worth investigating, whether it had psychologically similar effects to the ones described in the article from having a dearth of economic resources.
Or maybe I've just wandered off and am making no sense because it just doesn't work that way. Willing to hear it if so.
