It's Friday the 13th. You can celebrate by spending the day on the 13th floor of a tall building... oh wait, you can't, because our society is stupid and superstitious.
There's actually a word for being afraid of Friday the 13th: paraskavedekatriaphobia. Thank God we have lots of Greek words to put together like a German train wreck. I love this fact:
"It's been estimated that [U.S] $800 or $900 million is lost in business on this day because people will not fly or do business they would normally do."It's the 21st century, people! Here is an extensive history of Friday the 13th, filled with ancient anecdotes that are pure bullshit.
