I like to visit islands but I'm not sure if I would like to live on one of them. Islands are small and completely surrounded by water whereas I prefer land. Land gives one the feeling of more stability.
More stability does not necessarily mean more security. I live in a country which has the sea on one side and land on all its other sides, but this land is unfriendly, to say the least. So, I feel like living on an island from the transport point of view (to the outer world -by sea and air only), but it's worse than living on an island from other points of view: lack of peace - conflicts and wars with hostile neighboring countries.
Anyway, islands are being marketed to the tourist as little paradises. Many people with money buy a vacation house on the island of their choice. I once met a nice german woman who possesed such a house on a greek island. I sometimes found myself thinking about her and and her property with worry, because of the anti-german sentiments in Greece of the last years as a result of austerity measures imposed on the latter by the EU.
Now it sems the situation is quiet; until...next time when Greece needs a bailout.
Well, nothing is without some risk in this world.
