But one of the main reasons why Denmark does so well in international happiness surveys is the welfare state, as it reduces uncertainty, worries and stress in the population. You can say that Denmark is the happiest country in the world or you can say that Denmark is the least unhappy country in the world. The welfare state is really good (not perfect, but good) at reducing extreme unhappiness. Universal and free health care, free university education and relatively generous unemployment benefits go a long way towards reducing unhappiness.
Adults are not supposed to play. We are supposed to stress, have worries and be too busy dealing with life's problems. But according to a study undertaken by Princeton University and led by Alan Krueger, Professor in Economics and Public Affairs there, we are happiest when we are involved in engaging leisure activities.
The gross national product does not allow for the health of our children, the quality of their education or the joy of their play. It does not include the beauty of our poetry or the strength of our marriages; the intelligence of our public debate or the integrity of our public officials...it measures everything, in short, except that which makes life worthwhile.
