Reasons for living longer? We don’t shoot each other as often. We pay a lot of taxes so that our government can spend 83 billion dollars on social welfare.
That’s basically it. The top countries are the ones with low crime rates and high taxes (which means better social welfare and less poverty). Also the list of the best living conditions (Best countries to live in) is similar to this list. Junk food probably has something to do with it as well. And the great outdoors.
Although Australia’s one of those countries that wasn’t ever meant to be inhabited by humans. Apparently our water will run out completely in the near future unless we build more dams. We’re already on level 5 water restrictions where I am.
