Dumb people are always happy!

when you are dead you don't know that you are dead it's only difficult for the others

It is the same when you are stupid

I saw this somewhere and i think it's a bit true, simple people are much happier than "smart" people. It's a bit of a course to be able to over analyse & to compare. If people stop comparing against it's peer's people would be much happier. Smart is not so smart after all.
