I’m Swiss, but I was born and raised in the Gulf states. When I visit Switzerland during the cold season, I immediately become depressed, irritable, and in a bad mood. I prefer the heat 100%. I don’t think I could live in a place with a cold climate and be happy.
I can’t stand the heat (and stay the fuck out the kitchen) for real though 21 degrees is perfect, any more and it’s groin soup.
