I’m superstitious and will definitely notice the number 13. I will often take greater care when it’s Friday the 13th, but I have taken advantage of cheap tickets to fly on a Friday the 13th. I use to judge people for being superstitious. Now I just wonder to myself if the people who live or work on the 14th floor of a building feel better or worse knowing that there is no 13th floor. A 2007 Gallop Poll reported that 13% of people living in the U.S. would be “bothered if given a room on the 13th floor” of a hotel.
