It's another Friday the 13th and all of you super-superstitious types are hiding out at home.  But have you ever wondered why this particular date has the power to freak out so many people?

Seems that friggatriskaidekaphobia — "that’s the ACTUAL name for a fear of Friday the 13th" — was born of a combined fear of Fridays and the number 13 rather than just the date itself.

Some people believe that Friday the 13th is unlucky, because of significant events in Christian tradition said to have taken place on a Friday, such as the Crucifixion, Eve’s offer of that fateful apple to Adam, or the beginning of the Great Flood.

According to the website snopes.com here some things you should NOT do on Friday the 13th!
