Hey, this "study" made me laugh, does that improve the US's Joy Index?
By the way, as I type this, the radio is playing, the A/C is on; I have had enough to eat today. My shower was warm, I had soap and shampoo. The hair dryer worked.
Here's what North Korea, the country filled with joy, looks like at night:
South Korea is bright, North Korea is dark. This amazing image is included in the standard US Department of Defense briefings on North Korea. It was mentioned in a news briefing on 23 December 2002 by Defense Secretary Rumsfeld, who stated that "If you look at a picture from the sky of the Korean Peninsula at night, South Korea is filled with lights and energy and vitality and a booming economy; North Korea is dark." There are a number of versions of this image in circulation, with visible differences that vary according to the conditions at the time the imagery was acquired.
