Because it is believed that 13 is unlucky number, many buildings do not have a 13th floor – or rooms with the number “13”… Just like AlSeef Hospital 😉 Floor #13 does not show in their elevators

I guess to avoid testing fate, the number is disregarded – when it’s actually there 😉 It reminded me of one of Ellen Degeneres books I read back in college, when you reach chapter 13, she asks you to go to chapter 14 lol! Thats all there is in that chapter!
