From my perspective there are a few baked-in assumptions here:
Living in a city with the noise and smells is not itself physically (sensorily) painful.
You can afford to live in the city. (Rent/mortgage, utilities, transportation, et cetera.)
You can afford to buy delicious things in the city.
You socialize well enough with people that they want to feed you delicious things.
If you start unticking those boxes then it eventually may become a set of competing unhappinesses where you chose the least worst option.
@zygmyd all true in the N American context, but i basically grew up in a city state and never had any other way of life available to me, even if all of those things were not true.
i'm learning now about different ways of living, i'm glad they exist, but also, i am still deeply comforted by cities. and in this context, it's because they tend to be the only places that provide me with the cultural affinity i am after, vs being a complete outsider in places with far less diversity.
it's a reasonable cost for me, one that would take a lot to give up.
I have myself tried country, city, and suburban living and city living by far suits me. Likewise, it would take a lot for me to give this up.
