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.
Suicide is low in the UK and in Greece, which indicates it's down to culture. The UK is a chatty country where people talk to strangers all the time. Greece is a country with a strong family culture.
Scandinavia doesn't have a strong family culture, and people there tend to be reserved and not as chatty or friendly as the Brits. So loneliness is a thing. Suicide is a function of loneliness.
