In other words, this cleanness is definitely at someone else's expense, whether we like or not. And while we are at it, Europe is the most suicidal region in the whole world (with Scandinavian countries closer to the top of the list). So much for "happiness" (perhaps, they feel guilty, or something)
Suicidal goes by how dangerous life is. In countries where is war or lot of criminal and poverty no one will suicide. Because they see dying and what comes with that all the time. In countries with high living standards there is tones of suicides, because people simply dont cherish the life.
