Fur - a 22 square kilometers island in Limfjorden, Denmark with only 825 inhabitants. Niels Lykke-Sørensen is in sixth grade at the local school. "We're a boys-only class. There were girls in our class a couple of years ago, but they all left the island. But I still like this island. When I grow up I want to live here. Maybe get a job on the mainland and have a house here. An exciting job. A real-estate agent perhaps."
