From what I've read, countries closer to the North Pole who have abysmal winters, such as Scandinavia and Russia, their citizens seem to be prone to drink problems and depression as opposed to the southern Mediterranean for example who have far greater exposure to the sun. Whilst Finland is no doubt beautiful in the summer, I also understand they are beset by midges. I've only been to Denmark in Scandinavia, lovely people, but they can keep their winters, dark, cold and gloomy. No thanks! I think the weather is a big factor in determining the outlook of the people that inhabit countries with inhospitable climates imo.
