What are you afraid of if you suffer from triskaidekaphobia?

Explanation

Triskaidekaphobia comes from Greek and means a morbid fear of the number 13. Thirteen can be considered a 'bad' number just because it is one more than 12. The Babylonians thought the number 13 was the number of the underworld. There are also biblical overtones. At the Last Supper, Judas, the disciple who betrayed Jesus, was the 13th to sit at the table. The 13th chapter in the Book of Revelation is about the Anti-Christ. Famous people who have suffered from triskaidekaphobia include Napoleon and Mark Twain.
