baker's dozen

as far as i can remember this number is a jinx for me.... i always get uneasy whenever i have to face this number...
just an example: i once used jersey no. 13 in a basketball tourney... i got injured midway through the tournament and worst we lost in the championship game (maybe by 13 points, i don't remember)
then recently, i got a final social visit stamp in the immigration on the 13th page of my passport which was released last sept. 13...
we live in the 13th floor of a condo, our office is in door number W-10-13 and one of my client's office is at 13th floor....
i dont believe in these stuff but it is annoying and sometimes it gets under my skin...

what they say:
The early Romans thought 13 was a sign of death and destruction. And according to Norse mythology, if you sat 13 people down at a table, that was very unlucky. (Why? At a banquet of 12 people in Valhalla, an intruder –number 13 – caused the death of Balder’s son Odin). The number of people at the last supper of Christ and the twelve Apostles confirmed the superstition about the number 13 in witches were believed to meet in “covens” that hat 13 members.

Many hotels have no room 13, and many buildings have no 13th floor. Next time you fly, see if there is a row 13 in the plane. As date, 13 isn’t too lucky either, especially when it falls on Friday. That was always thought of as a really bad day to start a new project or to begin a ship voyage. Movers, doctors and dentists say their business drops on Friday the 13th. The good news is that a maximum of three Friday the 13th can occur in a year, and sometimes there is just one.

.... and yes, a baker's dozen is 13 pieces sometime called devil's dozen
