Cairo Named World's Most 24-Hour City
September 2, 2011 - Cairo has just been named the world's most 24-hour city.
A study done by Badoo.com, though not yet confirmed by an outside study, used 120 million online chats made over two months on its website to determine the results. Cairo beat out New York, which carries the title of "the city that never sleeps," as well as other top cities like London, Paris and Rome.
