Problem: (CNN)Shin Dong-hyuk's horrific descriptions of his time in a North Korean prison camp became a best-selling book, made him a key witness before the United Nations and grabbed headlines around the world.

He was one of the most high-profile North Korean defectors, winning several human rights awards and inspiring a documentary as his memoir was translated into 27 languages.

Now the publisher of the book and its author say Shin -- who claims to have been born in and escaped from a North Korean prison camp -- has revealed that parts of the story he told weren't true. Shin may have spent most of his life in North Korea at a different prison camp, rather than the total control zone that formed the title of his biography.

Shin's accounts of his time in the gulag have been widely reported in interviews with media including CNN. He also wrote an opinion piece describing his experiences for CNN Digital.

Don't discount N. Korean stories after defector's recanting, advocates say

Blaine Harden, author of the book "Escape from Camp 14," said in a statement on his website over the weekend that Shin had changed "key parts of his story."

"On Friday, Jan. 16, I learned that Shin Dong-hyuk, the North Korean prison camp survivor who is the subject of 'Escape from Camp 14,' had told friends an account of his life that differed substantially from my book," Harden said. "I contacted Shin, pressing him to detail the changes and explain why he had misled me."

Q: (Mental Floss) -- Over the centuries, people have had some very good reasons to dress up like a member of the opposite sex.

After record-setting Olympics athlete Stella Walsh died in 1980, it was revealed that she had indeed been a man.

And I'm not talking about people who live this way out of personal preference, or those who dress up for theater and entertainment.

Here are just five examples.

1. Cross-dressing to join the army

Until recently, women have rarely been allowed to serve as soldiers.

So what was a gal to do if she wanted to serve her country? Naturally, disguise herself as a man and join the troops.

At least 400 Civil War soldiers were women in drag. These included Union Army soldier "Frank Thompson" (also known as Sarah Edmonds), whose small frame and feminine mannerisms (rather than causing suspicion) made her an ideal spy, as she could spy on the Confederates disguised as... a woman!

She wasn't the first woman to don a male disguise and join the army, though. During the Revolutionary War, women fought as men on both sides.

Hannah Snell, for example, joined the British army to find her husband, who had walked out on her to enlist.

Once her true sex was discovered (thanks to a pesky groin injury), she became a national celebrity in Britain, and made a post-war career of performing in bars as the "Female Warrior." Mental Floss: The Confederacy's plan to conquer Latin America

Problem: After moving to New York, Brian Moore could not stop running into his ex-girlfriend. There were four awkward and unplanned encounters in six months, to be exact.

So while most social apps are about connecting with friends, family or good-looking strangers, Moore began to wonder if a mobile tool could use the same readily available location information to help you avoid certain people.

That's how he and Chris Baker were inspired to create Cloak, a free iPhone app that pulls in location check-ins from your contacts' Instagram and Foursquare accounts. It maps out the positions of people you know based on their most recent social posts so you can give them the slip.

Cloak's tagline is "Incognito mode for real life." You might say it's an anti-social network.

Click on a bubble on the map, and you'll see a person's name, his or her location and about how long ago he or she checked in there. If it was a while ago, the image will appear faded, like a ghost.

"We feel like we've reached the point of social fatigue -- too many networks with too much information, all the time," Baker says. "It's OK to turn off and pick up a copy of 'Walden' and just be alone."

The app lets people set up push alerts for acquaintances they'd prefer to avoid such as exes, frenemies or annoying co-workers. If someone wants to drop off the grid completely, he can set up these notifications for everyone in his social networks -- presumably while sneaking through dark alleys or hiding behind sunglasses and a hat.
