Why are Japanese very happy people?

This is something that I have observed for a while. I know that they are rich, but Americans are rich too. Is it because of the fact that they have an ethnically and linguistically homogeneous population in combination with one of the highest life expectancies in the world?

Well the majority of the population on the Internet generally are morons. It's not really something that's hidden and you have to look for. Stating such has nothing to do with being "tough". Being "tough" on the Internet is rather silly and pointless. Just idle on a reasonably popular IRC channel for a while, and the morons just find their way to you, no efforts required.

It's just stating an overall view; not insulting any one person. In fact, if I did not truly think that the majority of the population on the Internet were not morons, I would be insulting my own intelligence.
