The list is subjective as $&@#. Shoot Singapore and Hong Kong aren't really nations so much as City/States. I've been to Canada many times and it's absolutely beautiful there but it's also too €£¥#% cold for to much of the year. €£¥# half the top 10 in this list are in places far to cold for me. The list is based almost completely on subjective values and not on geography, topograpy, climate, culture, opportunity, etc, etc. Nor does it consider personal circumstances. I mean some of these selections don't make sense. Population density has a significant impact on quality of life. Hong Kong is a great city, I've been there once and my sister in law lives there but no way in €£¥# would I want to live in that over crowded megalopolis.
