Mille - it depends what definition for a Viking you use. It is not an ethnic group of people. I think that the best definition is that the Vikings were Baltic Sea People who were farmers, traders and seatravellers. To be a viking was a life style of that kind. Finns, Estonians and Baltic Sea Russians can also be included with the Scandinavians. The history of the Vikings has mostly been written in France and Britain and therefore the western origin is exaggerated. The Finns are old Europeans and the Indoeuropeans brought farming and language (related to farming) to Europe not so long time ago.

What comes to the "most balanced people in the world", usually Finland, Sweden, Denmark and Norway are on the top of any global ranking lists of skills, social well-being, innovations, happiness ... and also in economics - the countries have very high taxation and most common services are free of charge (education, health care, equality, pention - and many other basic services are state-provided and therefore individual incomes are less important). These countries are also famous for development aid, peace work, social equality and responsibility as well as environmental protection.
