Are you one of the 60 million people that suffer from paraskavedekatriaphobia?
How strange, that we relate bad things with the number 13. It's not only that we act weird on Friday the 13th but there is no gate 13 at aiports, planes don't have a number 13 seat or a row 13 and hotels don't have a room 13 (as it's the same here). We don't even let 13 people sit at a table, we add a seat for our friend the Ape to the table so that there are 14 seats.
How come we have such an obsession with this date? Apperently it has something to do with the combination of the number 6 (Friday is the 6th day of the week) and the number 13. I've been told that it relates to the church and the last supper: there were 12 diciples and Jesus at the table and Judas who betrayed Jesus was the 13th to arrive.
But what if your birthday falls on a Friday the 13th? Surely, that must bring luck!
