7 surprising things you didn't know about North Korea

According to National Geographic photographer David Guttenfelder, rollerblading is popular "all over the country." He reported that he couldn't "count the number of rollerblading locations there are in the capital city [Pyongyang]," in particular.

Drug use in North Korea is largely unregulated and quite common, with an estimated 30% of North Koreans using drugs, UPI reports. Known locally as yeoksam, marijuana is grown in such quantity that smugglers sneak it across the border into China for foreign sale, according to Radio Free Asia.

Public Radio International reports that methamphetamines, and specifically highly potent crystal meth, are also common in the DPRK, and though these drugs are not as openly permitted as pot, their use is widespread. Meth is often used less for recreational purposes and more as an appetite suppressant and to help workers toiling away for long hours at farms, factories, and in other trades.

Not only is the DPRK home to the biggest stadium in the world in terms of seating capacity, but it holds that distinction by a massive margin. The Rungrado 1st of May Stadium (also known as May Day Stadium) has a total capacity of 150,000 people.

It dwarfs the next largest stadium, which is Ann Arbor's Michigan Stadium, which accommodates 107,600 people. The venue is used for occasional sporting events, but its primary purpose is to host the annual Arirang Festival, a massive affair held each August and September that celebrates North Korean history, culture, and achievements.

Strange as it might seem for a dictatorship to hold elections, North Korean citizens go to the polls every five years. However, the ballots they receive only list one candidate name, for the office of Supreme People's Assembly deputy in their district, according to The Economist.

The only decision the voters have to make is whether to vote for the sole candidate listed or to vote against them, which involves placing their ballot in a separate box from the positive votes and having their identity noted, which could be considered an act of treason, The Economist reports.

As of August 15th, 2015, North Korea exists in its very own time zone, shifted at least a half-hour apart from any other place on earth, CNN reports. Pyongyang time is GMT+08:30, to be precise, and was adopted in an apparent return to the time the nation used prior to twentieth-century Japanese colonization.

To be clear, for many North Koreans almost every day is a struggle where food shortages, horrid work conditions, and government oppression define life. But for some DPRK citizens, everyday life bears some similarities to the rest of the world, NPR reports.

More and more North Koreans have access to mobile phones, DVD players, and other devices that were virtually unknown less than a generation ago, according to NPR. Recreational opportunities including movie theaters, amusement and water parks, and more are common in Pyongyang and a handful of other population centers, and influence from the wider world increases more with each passing year, NPR reports.
