Earlier quoted context omitted.
You’re projecting culturally-determined views about what “rich and happy” people do onto others. Rich people taking up sports and eating in moderation is a WASP thing. It’s much less of a thing in the south. And it’s not a thing at all in say the Indian subcontinent, where it’s unusual for adults to play sports.
I don't think so. Swedes aren't WASPs, but we are this way. I think Spanish people and Germans are too. I agree that it is as you say in India, but surely both Indian-Americans and Asian-American must become a bit this other way, since they'll probably work with many WASPs, and surely they get affected by media and general societal expectations?
My point is that suggesting that people who eat and gain weight must be unhappy and coping, because happy rich people play sports, is a culturally based assumption. American WASPs and Northern Europeans absolutely stand out in that respect. Even in East Asian cultures with strong social pressure to not gain weight, adults playing sports isn’t common.
