I agree that Americans are miserable people, which is why I no longer live there, but you were talking about "health" and then shifted the argument to "happiness".

In fact, I agree with everything you say in this post, but I don't agree with your previous claim that the stress of living in a Western society is "far more unhealthy" than the bad dietary choices in the East, because Westerners and particularly Americans are objectively healthier and longer-living - though miserable, tortured and annoying people, particularly the Yanks.
