Jan 18 Word of the Day
1. Blue Monday is the most depressing day of the year, calculated by Dr. Cliff Arnall, a researcher at the University of Cardiff's Center for Lifelong Learning.
Factors used to calculate the date included weather conditions, debt level, time since Christmas, time since failing our New Year's resolutions, low motivation and feeling the need to take action.

In 2005 the date was calculated as January 24th, in 2006 it was January 23rd, and in 2007 it was January 22nd.

2. A song by the hard rock band Orgy from their album Candy Ass.
1. Guy: "Aw man, I feel like absolute shit today."
Friend: "Yeah, same here. I hate Blue Monday."

2. "I wish I could sing Blue Monday to my ex-girlfriend, she's such a bitch."

Dia is becoming a popular girls name in many cultures. She's either a very cute little girl or a seemingly stuck-up woman until you get to know her. She has lots of class and expects a lot out of any man in her life. She's hard on people she knows but often harder on herself.
People often think her name is short for some other name like Diane but it's not. She also hates to be called Dee.
"Did you see the new girl in the other office? Her name is Dia she's pretty but stays to herself."

"Uh Dia, is that short for Diane?"

Denver International Airport, often called DIA, is, by land size, the largest international airport in the United States, and the third largest international airport in the world, after only King Fahd International Airport, and Montreal-Mirabel International Airport. Currently, Denver International Airport is the sixth busiest airport in the United States in terms of traffic. The airport is located in far northeastern Denver, Colorado. Operated by the City and County of Denver, in 2005 it served 43,387,513 passengers, ranking eleventh worldwide (in the past it has ranked among the top ten busiest airports in the world). Denver is also the busiest (and largest) airport in the US without any non-stop service to and from Asia, except for direct flights to Tokyo-Narita via Seattle/Tacoma. DIA was voted the 2005 Best Airport in North America by readers of Business Traveler Magazine.

DIA has a very good reputation for being safe and fast. DIA also received the fewest amount of TSA-screener related complaints as of 2009 with only 5 complaints within a 45 month period.

It is also known for its innovative and very distinguishable roof made of white tension fabric meant to resemble the Rocky Mountains. But unless you live in Denver, you'll probably have no clue what the hell those things are.
DIA is an awesome airport that is very easy to get around and the staff is all very friendly for the most part.
