Icelanders believe in elves and trolls, to the extent that construction projects are sometimes diverted to avoid disturbing their mythical dwelling places.
Iceland does not have a military and has maintained a long-standing policy of neutrality, making it one of the few countries in the world without armed forces.
Iceland has an app called "Íslendinga-App" that helps prevent accidental incest by allowing people to bump their phones together to see if they are too closely related.
