What should the voting age be?

There is both a huge mountain running through the middle of Norway and there are big populations(granted, in a Norwegian scale) on both sides with very few in-between. If what you say is true: why is Norway a country?

Because the pattern of settlement was influenced by marine factors.

Much easier to keep everyone feeling they belong in Norway if they feel connected by the sea.

There is no sea route to any of Spain's either historical or present day capitals they pretty much been inland for a long while now.

Plus the Basques and Catalans are probably more likely to oreient to a Northern power centre even if they have arguements with France part of the ancient Homelands are the other side of the Pyrennes.
