Number Fact about 13

If you are currently freaking out about the number 13, it may be because you suffer from triskaidekaphobia – fear of the number 13. We are so scared of the number 13 that it costs the worlds billions of dollars a year in absenteeism, travel cancellations and loss of business. You may have noticed in most hotels you won’t find room numbers like 613 or 2513 because they contain the number 13. In fact, the whole 13th floor is left out, to be safe.

Personally, it is my favourite and lucky number and is a Fibonacci number!!!
