A hundred years ago, if your ship sank on the high seas, you would be lucky to survive by hanging on to a piece of driftwood, or one of the wooden elements of the vessel. The ocean might even have ended up pushing you onto the shores of a deserted island, where you save a native whom you then decide to call Friday.

In a modern version of the Robinson Crusoe tale, the fisherman sets sail on Friday, and when shipwrecked, does not hang on to a piece of wood but clings on to a plastic cool box for two days. There is no washing ashore. Instead, the Colombian coast guard stumbled across the unlucky-lucky man on the high seas and brought him – and the cool box – back to shore.
