There seems to be a never-ending stream of 'Scandinavian lifestyle trends' in international glossy magazines, but only some of them are worth pursuing, while others are all hype and little reward.
Originally a Norwegian invention, 'friluftsliv' is popular across Scandinavia and is one of many exported words which portrays the locals as special mythical beings when, in reality, they are much more like the rest of us than the online trends suggest.
The Swedes joke about the Norwegians, the Norwegians about the Swedes, and the Danes about both, or perhaps neither. But the mostly friendly joshing between Scandinavian countries is more recent than you might think.
