Some superstitions are too sticky; you could almost imagine it will still exist even after man has built a home in Mars.

Take Friday the 13th as an example. History records suggest people did not pay attention to the day-and-date combo before the 19th century. An author says talks of the Friday the 13th bad luck started to spread after the publication of Thomas W. Lawson's popular novel "Friday, the Thirteenth." It is about Wall Street trading associated with bad luck.

Today on Twitter, Friday the 13th is a trending topic. In a world where toddlers play with iPad, some people continue to believe that old superstitions still hold.
