What? Switzerland happy? What a stupid study is that? Switzerland is number one in the world in suicide. Switzerland is only happy in terms of money. In whole Europe there is lots of depression and sadness, because God is crying all day long about Europe, so much atheism and apostasy. Switzerland might be more happy than Germany or France, but if you want to have happy, i.e. if you want to go to a place where God or the Holy Spirit is happy, i.e. it really feels happy in the air, your best bet is Costa Rica or Nicaragua.
Nicaragua feels less happy than Costa Rica, probably God is still sad because of the war, and people seem a bit sad because of the poverty, but still I love Nicaragua more than Costa Rica, because God has made me to serve poor people, and so that's how my heart functions.
And to the question if I'm happy:
I've never been happier before in my life than in Nicaragua, except when Jesus came into my heart.
But, in order to get happy in Nicaragua, you need to give to the poor, then you will be the most rich & happy guy walking on this planet with no money in your pocket. Because giving is more blessed than taking, and in Nicaragua this proverb becomes even more true.
There might be parts of Switzerland also feeling happy like Bern or Thun, where lot's of people honor God, but my hometown Basel, it's the devils capital of Switzerland, there is a lot of depression and lot's of people are sad.
