Human thought can do anything.
In the 1950s, an English container ship carrying bottles of Madeira wine from Portugal unloaded its cargo in a Scottish port. A sailor enters the cold room to check that everything has been delivered. Ignoring his presence, another sailor closes the door from the outside. The prisoner strikes the bulkheads with all his strength but no one hears him and the ship leaves for Portugal.
The man discovers enough food but he knows that he can not survive long in this cold place. Yet he finds the energy to grab a piece of metal and engrave on the walls, hour after hour, day after day, the story of his ordeal. With scientific precision, he recounts his agony. How the cold numbs him, freezing his nose, his fingers and his toes. It describes how the bite of the air gets intolerable burn.
When the boat drops anchor in Lisbon, the captain who opens the container discovers the dead sailor. We read his story engraved on the walls. The most amazing is not there. The captain raises the temperature inside the container. The thermometer reads 19 ° C. Since the place no longer contained any goods, the refrigeration system was not activated during the return trip.
The man was dead only because he "thought" to be cold. He had been the victim of his only imagination.
