poverty-related concerns consume mental resources
This is good stuff.
Seriously though, the "poor people" I drive by on my way home always look like the LEAST STRESSED people in the world. Like, not a single frick to give. Smiling, laughing, drinking, and just hanging out. Sometimes playing card games outside, other times BBQing. Small sample size and maybe they are actually well off but just choose to live in what appears to be "poor conditions". I really don't know. But they definitely don't look stressed at all.
