Some people will go to great lengths to avoid the nuber 13. Hotel owners do not usually assign the number 13 to a room, preferring to label it 12A or 14 instead. The French never issue the house address 13, while in Italy the number 13 is omitted from the national lottery. Airlines have no thirteenth row on their planes, and office and apartment buildings rarely have a thirteenth floor.
From ancient civilizations to modern societies, the belief in the magic of numbers has persisted in spite of the advances in science and technology. There is nothing quite as stubborn as superstitions. Even today in the twenty-first century, people still believe in bad luck and omens. In the future, people may work in space stations or travel the universe in starships, but there probably won't be a "Starbase 13" or a rocket liftoff on friday the thirteenth. A sevent voyage will be a good on, and the third time around will still be lucky... :)
