To celebrate its 15-year anniversary, Wikipedia has released data on which of its pages have been edited the most over the course of its existence.

George W. Bush took the top spot with 45,862 edits, 3,000 ahead of the World Wrestling Entertainment (WWE) roster page. The rest of the list is a mixture of controversial figures, pages that need to constantly be updated, and Wikipedia itself.

In total, Wikipedia says that its 5,053,647 articles have been edited 808,187,367 times.

Here is Wikipedia's list:

We had previously looked at the most controversial Wikipedia pages and examined which aspects of the legacies of famous figures were still being fought over.

Below we've included the list of the 27 most edited pages of people on Wikipedia, along with a sample edit from each that highlights an area of controversy. Edits removing portions of the text are shown in red, and edits adding new text are shown in blue.

The list spans from Britney Spears and Jesus to Bill Clinton and Adolf Hitler:

Per Se opened its doors in February 2004 and has since garnered three Michelin stars and accolades from diners and critics around the world ... that is, from many critics who aren't named Pete Wells.

This week, the New York Times restaurant critic obliterated the venerated New York restaurant in his latest review, stripping it of two stars (leaving it with two) and painting a picture of a revered restaurant's fall from grace.

Yes, you could certainly find a cheaper meal in this city, and it might even be just as enjoyable; but for someone who simply wants to share a unique dining experience with loved ones, in a restaurant that is still one of New York's most important, Per Se is just fine.

I recently got the chance to eat at the restaurant from chef Thomas Keller, where no detail is spared. Fortunately, I did not experience a dirty-bong-water bouillon or a limp yam dumpling as Wells did. Instead, I experienced dishes that were playfully arranged, ingredients that were thoughtfully sourced, and a staff that was attentive but not suffocating.

Here's what it was like, from my (very hungry) first steps entering the restaurant to my last stuffed and satisfied steps out.

Enter Per Se, located on the fourth floor of the Time Warner building in Midtown Manhattan. You'll be greeted by a set of iconic blue doors, also seen at Keller's restaurant The French Laundry in California. By the way, these blue doors don't actually open — the entrance is to the side of them. Per Se is playful in this way, and it's a theme that'll reoccur throughout the meal.

The dining room is modern, minimal, and effortlessly classic. You'll see only a few materials used throughout: wood, steel, and flowers.

And, of course, there's a sweeping view of Columbus Circle.

Pilates doesn't exactly look like much of a workout. But I went to a class at New York Pilates, and let me assure you: It was a challenge.

According to Pilates Method Alliance, more than 11 million people practice the low-impact, total body workout.

After only one session, my entire body was sore. I worked muscles I didn't realize were out of shape. Days after the class, it was still hard to climb the stairs.

John Krasinski is known best for his comedic work, like lovable Jim Halpert on "The Office."

But starting Friday, we'll see him in a new way as he stars in his first action movie, Michael Bay's "13 Hours: The Secret Soldiers of Benghazi."

Krasinski told Men's Health he had just four months to train in preparation for the role of a Navy SEAL who defended the American diplomatic compound in Benghazi. After all, he had to look the part.

"I gotta be honest: It was brutal at times," Krasinski said. "We did tons of metabolic work, dragging sleds and all this stuff I've seen NFL players do."

"My body fat was, I believe, 25%," Krasinski told Jimmy Kimmel on Kimmel's late-night show. "And then by the time I did the movie my body fat was 9%."

Krasinski doesn't go out of his way to show off his new body in the movie, aside from one shirtless shot toward the end. But it was important to authentically play one of the six members of a security team that helped protect Americans in the 2012 terrorist attack in Libya that resulted in the death of Ambassador J. Christopher Stevens.

Here are some highlights from Krasinski's experience getting fit for the movie, via Men's Health, including his favorite workout to do:

Favorite workout song: "What More Can I Say," Jay Z.

Favorite exercise: "Bench press. There's that number you can keep pushing. It's almost a game instead of a workout."

Least favorite workout: "Bulgarian split squat."

At first glance, the Black Ant seems like your average Mexican restaurant. The restaurant's trendy decor reflects its location in New York City's East Village neighborhood.

But a visit to the kitchen makes diners realize that they're in for a unique experience. Among the fresh ingredients that the Black Ant sources from Mexico are grasshoppers and ants. And yes, they use these bugs in their food.

Intrigued by this unusual menu twist, we decided to give Black Ant a try. We were served two of the restaurant's most popular menu items: guacamole, and croquettes. The guacamole was topped with whole grasshoppers, while the croquettes featured the bugs mixed into the flour, as well as a whole bug on top.

Surprisingly, the grasshoppers didn't add much of a taste, but they did add some nice texture to the food. They're crunchy, but not bursting with flavor, so they simply compliment the dish they're added to.

If bugs aren't for you, Black Ant has plenty of options that are bug-less, such as a delicious all vegetable dish. But we recommend being adventurous and giving the bugs a chance. We're happy we did.

Posting a selfie on Facebook can lead to hard time — if you are a felon and are posing with a gun.

On Thursday, a federal judge sentenced a Knoxville man to 15 years and eight months in prison for being a "felon in possession of a gun," according to the Knoxville News Sentinel.

The conviction came primarily from a selfie the man posted in October 2013 on Facebook. In the photo, he holds a .45-caliber handgun above his head.

The man, 42-year-old Malik First Born Allah Farrad, had two prior convictions for gun possession, according to the Sentinel.

But he's not the only one to get in trouble after posting selfies. Here are 10 people arrested after posting selfies in compromising situations (ages are from the time of the incident):

Two girls took this scary selfie before allegedly robbing a restaurant in Sweden. Police tracked them down and arrested them at one of their grandmother's homes.

Kayleigh Hill ran out onto a baseball field during the 2013 College World Series game and filmed herself being tackled by security guards on Vine, all for the sake of a really good selfie.

A man in Milan allegedly stole an iPad then took a selfie with it. The selfie was accessed on iCloud by the person he reportedly stole the iPad from. He was then arrested.

Regardless of your gender, career, financial status, health, or overall well-being, chances are you're going to start feeling differently in your mid-40s.

The bad news is this change is not for the better.

The good news is that it isn't permanent, and you can prepare for it by recognizing the symptoms, which can include dissatisfaction, lowered self-esteem, and an overall sense of unhappiness.

This torrent of emotional turmoil is often referred to as a midlife crisis, and it can make us take drastic, uncharacteristic measures — like leaving our spouse or quitting our job — in an attempt to subdue the chaos.

When it hits

Most people start to experience symptoms in their mid-40s and 50s, with the average age of onset being 46, according to a 2008 paper that looked at a random sample of 500,000 Americans and West Europeans.

In another study, published in 2010, researchers used information from a phone survey of more than 340,000 Americans between the ages of 18 and 85 done over a 30-day period.

The survey measured participants' sense of well-being through a series of questions about their level of satisfaction with various parts of their lives, including standard of living and their community, job, relationships, and personal health.

The researchers found data to suggest that people who are nearing their 40s experience a lower sense of life satisfaction than those who are aging past their 50s. That means if you haven't hit 40 yet, then you might be on a downward spiral, but the good news is that it won't last forever.

Fundamental issues at play

Scientists have also found evidence that midlife crises transcend cultures and countries.

For example, Hannes Schwandt, a postdoctoral research associate at Princeton University's Center for Health, studied a detailed survey of 23,000 people from several different parts of Germany taken from 1991 to 2004.

The survey asked the individuals to report how satisfied they were currently and how satisfied they expected they'd feel five years in the future.

He discovered a couple of remarkable things:

• First, younger people had overly optimistic aspirations for their futures.
• Second, people who were the least satisfied were also the ones who tended to have all the things associated with a desirable life, from high levels of education to steady jobs.

"They feel ungrateful and disappointed with themselves particularly because their discontent seems so unjustified — which creates a potentially vicious circle," Schwandt writes.

Unanswered questions

There are still a few aspects of a midlife crisis Schwandt says he doesn't fully understand.

For one, why does the crisis hit people who are all a similar age? Why doesn't it plague us when we're retiring in our 60s or building a career in our 20s?

The root of the problem, reasons Schwandt, is an overwhelming sense of regret spawned by not meeting one's own lofty expectations. He offers one explanation in the Harvard Business Review:

"As we age, things often don't turn out as nicely as we planned," he writes. "We may not climb up the career ladder as quickly as we wished. Or we do, only to find that prestige and a high income are not as satisfying as we expected them to be."

The most frightening thing about midlife crises is they seem to strike without warning, taking people by complete surprise, Schwandt writes.

Overcoming the slump

Schwandt and others have a few suggestions for how to handle a midlife slump.

"When I give lectures, I say we're stuck with this, but at least you know it's completely normal if you're feeling low in your 40s," University of Warwick professor of economics Andrew Oswald told The Atlantic's Jonathan Rauch. "And when you're low, you blame the wrong things."

Since this type of midlife crisis is likely not caused by any single outside source, like a job or a spouse, quitting your job or leaving your long-term partner probably won't solve anything.

Instead, Schwandt suggests being patient. Take a step back, reassess your personal goals, and embrace the life you're living.

"The data seems to suggest that if you're in the throes of a mid-career crisis, maybe you should just wait it out until the U-curve's upward slope is reached," Schwandt writes. "This combination of accepting life and feeling less regret about the past is what makes life satisfaction increase again."

Virgin Galactic unveiled the look of its new flight suits at Spaceport America in New Mexico Thursday, announced as a collaboration with Adidas' high-end sportswear brand Y-3. 

The jumpsuit the company unveiled was the pilot's version, which is still a prototype, but passenger astronauts will also be outfitted with similar suits.

Y-3, which is a collaboration between Japanese designer Yohji Yamamoto and Adidas, will also design all other Virgin Galactic uniforms — including crew members on the ground — for the partnership.

It's made with super high-tech fabrics. The body uses a fabric called Nomex Meta Aramid, which retains Kevlar's rigidity but is more flexible, according to Gizmodo.

This makes it able to support a pilot's seated position while blasting through the atmosphere, while also staying comfortable enough to wear during long space flights.

The boots are similarly high-tech, using a combination of Nomex and natural leather that is extremely lightweight. They also have special insoles for absorbing shock as well as enhanced grips on the bottom.

The boots go into testing with pilots immediately, so they can provide feedback.

The outfits take clear inspiration from popular sportswear motifs, like "goth ninja" and "health goth," which also include all-black palettes and high-tech materials.

Since these suits are just prototypes, it's possible the design might change completely before they go into production, but we hope they don't.

Wearing flight suits this cool might just make the entire trip worth it.

Istanbul's Grand Bazaar is one of the oldest covered markets in the world.

With more than 3,000 shops taking up a total of 61 streets, it's a major tourist hub — it had more than 91 million visitors in 2014 alone, making it the number one tourist attraction in the world.

More than 26,000 people are employed at the bazaar, and many shops are family-owned. 

Getty photographer Chris McGrath recently paid a visit to the market, taking portraits of the shopkeepers in front of the most elaborate storefronts he saw.

They were all packed to the brim with majestic items.

The year 2016 may finally be when beards come to an end.

According to an interview The Times UK did with historian Alun Withey, an academic who will run a three-year research project on the beard and its cultural history in the UK, people have been predicting the end of the beard since 2013.

Each time it seems they've been wrong, and the beard has maintained as strong as ever in the eyes of the public.

"People have been predicting the fall of them since 2014 and that Peak Beard has been reached," he told The Times UK.

This time however, it's really ending. Like, actually. He says it's all down to the historical pattern, which, according to his data, is predicting a huge decline right around now.

"There will be a backlash," he said. "They are divisive. There is already a backlash in the United States where there’s a new ideal; the yuccie."

The yuccie, as determined by writer David Yi at Mashable, is a "Young Urban Creative." 

Withey says this class is in ascendance, and with it will come the end of the era of beards, since yuccies prefer a "stricter, sleeker look." They will eventually become the defining class.

This trend can even be seen in our list of the best-dressed men at the Golden Globes, where a majority were clean-shaven.

But don't worry. The beard trend of the early 2010s will still have its place in history. 

"The hipster beard, or lumberjack beard, is going to be the defining facial hair of this generation," Withey said.

This mom got to hug the woman who saved her son’s life.

Jake Amato was diagnosed with acute lymphoblastic leukemia when he was 4 years old. “I always felt sick. I had to take a lot of medicine. I never felt good,” Jake said. He was on chemotherapy for almost four years.  “Living in the hospital, sticking needles into my son’s body, filling him with chemicals. It was almost like a horror movie,” Jake’s dad said.

The cancer was aggressive and returned even after chemotherapy. “We were told that his best chance for survival is a bone marrow transplant,” Jake’s mom said.

After some searching, they found a match. The match was Carrie Ann, from Germany.

His transplant happened on September 15, 2010. It was successful and Jake has been cancer-free since.

Two years post-transplant, they were able to contact the donor and arranged a meeting. “824 days post transplant we met the person that saved Jake’s life,” Jake’s mom said.  The family of four waited at the airport for Carrie Ann to emerge. The following embrace was moving.

“It felt like meeting some old friends,” Carrie Ann said.

“She’s an angel. I went up to her and I said ‘you saved my son’s life.’ “Because she did, she saved my son’s life,” Jake’s dad said.

People are obsessed with measuring their daily health and fitness, and new technologies are constantly created to make it easier to track.

Wearing Athos fitness apparel is like having an electrocardiogram (EKG) done during your workout. Using eight censors in the shorts and 12 in the shirt, the clothing tracks your body's heart rate and muscle usage.

In real-time on a smartphone, you can see what muscles are firing and how hard. This gives you the ability see the balance between muscles during a workout.

Why does it matter? Without realizing, people with minor injuries often use different muscles to compensate, and  to avoid pain. This can cause new injuries to arise, and create bad habits in your workout.

Athos gives you the ability to monitor and ensure you are balancing your muscle usage evenly during a workout.

If you haven't mastered some of the most essential life skills already, it may be time to take a different approach.

Whether you're looking to listen better or negotiate for a raise, here are 13 surprising ways you can master some essential life skills.

SEE ALSO: People shared the deepest insights they've ever heard, and they may forever change how you think

Listening

It's a surprisingly simple yet underused concept: If you want to listen better, keep your mouth shut.

As Austrian pianist Alfred Brendel once said, "The word listen contains the same letters as the word silent."

Not only does thinking about what you're going to say next take your attention away from the speaker, but hijacking the conversation shows that you think you have something more important to say.

Conserving willpower

As Florida State psychologist Roy Baumeister details in his book "Willpower: The Greatest Human Strength," we all have a finite amount of willpower in a given day. The key to conserving it is to limit the number of decisions you have to make.

Startup founder Julie Sygiel, a very busy entrepreneur, follows in the footsteps of Mark Zuckerberg and President Barack Obama by wearing a uniform every day.

"Almost everything in my closet is black, gray, or blue and every top goes with every bottom," she tells Business Insider. "The only question I ask myself when getting dressed is: 'Do I need fancy shoes today?' All of my sweaters and pants are versatile and can look casual or dressy, so my shoes are the key piece that determines the overall look.

"It's amazing how much quicker I get dressed in the morning, and it allows me to save more creative decision-making energy for important choices at the office."

Time management

Warren Buffett once said, "The difference between successful people and very successful people is that very successful people say ‘no' to almost everything."

If you don't prioritize your time over others', you'll find your productivity will suffer and resentment will mount.

Some of the most successful business people not only work hard, but sleep less, too.

But it's not easy to function on just a few hours of sleep. 

Online mattress and bedding company SleepyPeople.com tipped us on a list of sleep hacks it put together recently.

Follow these simple hacks and you'll have a much better time sleeping.

SEE ALSO: 19 LinkedIn hacks that could help your business make tons of money

Honor your body clock. Set yourself a sleep schedule and stick to the routine. You'll feel better every morning.

Take it easy before bed.Don't work right up to the moment you go to bed. Your body deserves some "me time" to wind down every night. Try to spend half an hour every night before sleep to read a book or watch TV, and you'll be much more productive the next day.

Ban screens from the bedroom. It removes distractions and lets you have a deeper sleep.

So you want to be happier, healthier, and more successful in 2016?

Faced with unlimited advice and little time to spare, it's hard to know where to start.

#BIBetter is a 21-day self-improvement program designed for the busy professional, featuring a few habits that will make a big difference and a bunch of tasks that most of us have been putting off for too long.

We recommend participating with at least one other person, so you have more fun and keep each other in check. You can start on any Monday and should complete actions on their specified day when possible.

MONDAY, DAY 1: Floss your teeth. Do it every day for the rest of your life.

Believe it or not, as many as 50% of Americans say they don't floss every day. If you are one of those people, then make today the day you start doing it consistently.

How can you get in the habit?

Stanford psychologist B.J. Fogg is one of the foremost researchers on habit formation. The takeaway from all his work: Floss one tooth.

As in, if you're trying to form a habit, it can be helpful to start as small as possible, with a minimum viable habit. The point, Fogg emphasizes, is to insert the structure of the activity in your day, rather than doing it perfectly every time. This way of thinking works for all habits, and it works for flossing, too — and if you floss the whole mouth, then you're doing even better.

Indeed, this core dental hygiene technique will clean your teeth and gums of plaque, protecting your teeth as you age and saving you on dental bills. Some studies have even found that flossing is associated with a lower risk of heart disease, diabetes, and dementia.

TUESDAY, DAY 2: Break a sweat. Do it every day for the rest of your life.

For a wide range of ailments, exercise is an almost magical cure, which "can improve memory and concentration, lessen sleep disorders, aid heart disease by lowering cholesterol and reducing blood pressure, help sexual problems such as erectile dysfunction, and raise low libido," notes Slate.

Just a little bit of exercise has huge benefits. Research shows that running just five to 10 minutes a day can add years to your life, and if you establish that minimum habit now of doing at least that, you can build on it. A seven-minute workout using interval training can make a huge difference.

Longer workouts are obviously great, too.

Think you're too busy to work out? Tell that to GE CEO Jeff Immelt, who gets up at 5:30 every morning for a cardio workout; or Xerox CEO Ursula Burns who has an hour of personal training at 6 a.m. twice a week; or Twitter and Square CEO Jack Dorsey, who gets up similarly early to take six-mile jogs; or Starbucks CEO Howard Schultz, who likes to ride his bike every morning.

WEDNESDAY, DAY 3: Write in a journal. Do it every day for the rest of this program.

Psychologists have been studying "expressive writing," or journaling about difficult moments in your life, for a few decades. They've found that a few minutes journaling improves everything from mood to immune system to sporting performance.

It works for work, too: A Harvard Business School study found that people who wrote about their jobs improved their performance by 23%.

"When people have the opportunity to reflect, they experience a boost in self-efficacy," says HBS professor Francesca Gino. "They feel more confident that they can achieve things. As a result, they put more effort into what they're doing and what they learn."

So as a part of this life-improvement adventure, we're asking you to reflect on your day, plus on whatever journeys we send you on. You should also take the opportunity to look at the tasks that lie ahead and start making plans for the ones that require preparation.

If you find journaling to be useful, then we encourage you to keep it up for the rest of your life.
