I'm American and retired, slow travelling asia the last year, and just noticed how much less angry I am. Been to thailand, vietnam, china etc, and generally people are so much more chill, happy, keep their opinions to themselves etc.
When i was back to visit last week, i noticed how people are just angry, always telling you what you're doing wrong, move faster, agitated etc. Wondering what about the US just produces so many angry people?
I'm not saying there aren't angry, unhappy people elsewhere, but i notice it MUCH more in the US
