I wanted to write about Friday the 13th and how the Knights Templar, who are associate with setting up the Modern Day Banking System, were a part of the origins.
While doing a little research I found that the true origins are really not documented, only speculated, and there are quite a few.
This is an interesting article outlining where the superstition came from www.todayifoundout.com. Hopefully if you have a fear of Friday the 13th, Triskaidekaphobia, this will quell your fears.
