I've often said, if you live in an island nation of a few people, wouldn't you think it a must to try to keep everyone healthy, happy and strong? You know, in case the natives from the next island over decide they want to come and hurt all of you and take all your stuff? Health, both physical and mental are more important the smaller the population gets. Here's something I saw posted on facebook by one of my Swedish friends. What if there were only 100 people in the world and you applied current world statistics to them? This website says it would look like this.
Food for thought.
