triskaidekaphobia - fear of the number 13.

---> Thirteen may be considered a "bad" number simply because it is one more than 12, which is a popularly used number in many cultures (due to it being a highly composite number). When a group of 13 objects is divided into two, three, four or six equal groups, there is always one leftover object.

---> The number 13 also retains biblical meanings. At the Last Supper, Judas, the disciple who betrayed Jesus, was the 13th to sit at the table (also spilling the salt).

i particularly liked this. :D

---> The composer Arnold Schoenberg suffered from triskaidekaphobia. It is said that the reason his late opera is called Moses and Aron, rather than Moses and Aaron (the correct spelling with two As) is because the latter spelling has thirteen letters in it. He was born (and, it turned out, died) on the thirteenth of the month, and thought of this as a portent. He once refused to rent a house because it had the number 13, and feared turning 76, because its digits add up to thirteen. In an interesting story, it is believed that he feared Friday, July 13 1951, as it was the first Friday the 13th of his 76th year. He reportedly stayed in bed that day preparing for what he thought as his death day. After begging her husband to wake up and "quit his nonsense," his skeptical wife was shocked when her husband simply uttered the word "harmony" and died. His time of death was 11:47 p.m., 13 minutes until midnight. Also, note that the digits of the time of his death add to 13 (1+1+4+7).

---> American singer-songwriter John Mayer had 14 tracks on his album Room for Squares, although the 13th is 0.2 seconds of silence and is not listed on the album cover. Likewise, Hot Hot Heat's album Elevator does not list a 13th track on its cover. On the CD the 13th track is four seconds of random noise. The reasoning behind it is that since some buildings do not have 13th floors, an elevator would not have a button for it.

so, ano? takot na kayo sa 13? haha. superstitions. we still have that one, sovereign god in whom we could trust all our fears. :D diba?
