UFC icon Ronda Rousey shocked the fight world when she signed a full-time contract with WWE in January.

She made a surprise appearance at the Royal Rumble and made her professional wrestling debut at WrestleMania 34 on April 8 — WWE's biggest show of the year.

Rousey is one of the most famous fighters in the history of women's mixed martial arts. The 30-year-old won a bronze medal at the 2008 Olympic Games, a Strikeforce bantamweight title, and a UFC bantamweight world title.

But what does she eat to remain ring-ready? Well, Rousey is a known advocate of the Warrior's Diet (fresh fruit, vegetables, and intermittent fasting), as well as the Dolce Diet, a meal plan put together by her own nutritionist Mike Dolce.

Here's what she eats for breakfast, lunch, and dinner on a typical day.

10. Korean Air, South Korea.

One TripAdvisor reviewer said: "We travelled from Chicago to Hong Kong with our toddler, and could not have been more pleased with the experience. Basic economy on KA is basically economy plus on other (especially US-based) airlines. The flight staff actually made me like the experience, rather than detract from it. I’ll be flying KA whenever possible in the future."

9. Azul, Brazil.

"Azul is a lovely airline, employing a fleet of Embraer regional jets offering 2 + 2 seating," according to one user. "Service is efficient and you always get a package of 'aviõezinhos' (airplane shaped gummy bears) to chew on the short domestic hops."

8. Qatar Airways.

One reviewer who claims to be a frequent traveller said: "Qatar is one of my favourite airlines to travel with. The bar in a380 (business class) is the best. The service regardless of class is fab. The treatment of frequent fliers is great... food very tasty for economy ... and very big portions… Entertainment is top notch. They are one of my favourite airlines for eco travel."

• "A Quiet Place" is now a box-office hit, which isn't just a surprise for most in Hollywood, but also for those who made it.
• The production company behind the movie, Platinum Dunes, told Business Insider about the test screening that left its audience confused, and the anxiety of showing the finished movie for the first time.

Warning: Mild spoiler below if you haven't seen "A Quiet Place"

This weekend Paramount’s new horror movie, “A Quiet Place,” about a family forced to live in silence to hide from monsters that kill anything that makes a sound, won the weekend box office after earning an impressive $50 million domestically — exceeding all industry projections.

Made for $17 million, the third (and by far most successful) directing effort by actor John Krasinski snuck up on everyone in Hollywood to become the latest hit horror movie. And according to the producers behind the movie, Andrew Form and Bradley Fuller of Platinum Dunes, no one involved with the movie knew they had a potential hit on their hands until about a month ago.

Horror remake kings

Form and Fuller, along with their mega-blockbuster filmmaker friend Michael Bay, started Platinum Dunes in 2001 and quickly made a name for themselves remaking classic horrors like “The Texas Chainsaw Massacre” (2003), “The Amityville Horror” (2005), “Friday the 13” (2009), and “A Nightmare on Elm Street (2010). They made a nice profit on all of them — “Chainsaw Massacre” made $107 million worldwide on a $9.5 million budget, “Amityville” made $108 million worldwide on a budget of $19 million, and “Elm Street” made over $115 million worldwide on a $35 million budget.

Since then, the company has expanded its portfolio. It got the rights to the Teenage Mutant Ninja Turtles, releasing two movies on the characters for Paramount. It teamed with Jason Blum at Blumhouse Productions to make “The Purge” movies — three releases have earned a combined $319.8 million worldwide (all made for $10 million or under), with a prequel, “The First Purge,” coming July 4. And it's developing TV projects like “The Last Ship” for TNT and the upcoming Amazon series, “Jack Ryan,” starring Krasinski.

But Platinum Dunes’ comfort zone will always be horror, and it proved this weekend it’s a major player in the genre.

Krasinski's power play

Screenwriters Bryan Woods and Scott Beck wrote the “A Quiet Place” script on spec and 18 months ago, while deep into preproduction on “Jack Ryan,” Form and Fuller got a call from their agents at WME that they wanted to pass along the script, which they described as a “high concept” genre movie.

“They send it over and the script is 67 or 68 pages long, and I'm like, 'This is a movie? This is like a one-hour pilot,'” Form told Business Insider. “When we went through it you realize there's no dialogue in the movie. The script had a map of the farm and numbers on a page for a countdown. There were literally pages that were just one number. So it wasn’t even like the script had pages of full text. But the story was there.”

They took the project to Paramount, where Platinum Dunes has a first look deal, and the studio bought it. Then Form and Fuller reached out to their “Jack Ryan” star, John Krasinski, to see if he would play the role of the father in the movie, Lee Abbott.

“John called back a couple of weeks later and said, 'I definitely want to play the dad, but I also want to rewrite the script and direct it,’” Form said. He and Fuller quickly agreed.

The project became even more attractive when Krasinski’s wife, Emily Blunt, signed on to play the role of the mother. On paper, it all seemed right. But would audiences get a “silent” horror movie?

A test screening leads to lots of anxiety

Form and Fuller said they only did one test screening of the movie before its world premiere at the South by Southwest Film Festival in March, and it got mixed reactions because of one obvious omission.

“The big problem was there was no creature in the test,” Form said. “It was either plates or a motion-capture actor. Sometimes John was in the motion capture suit playing the monster. In that basement scene he was the creature down there.”

Not having a creature in the test screening was most apparent in the scene where the monster runs away from the daughter, Regan (Millicent Simmonds), because her hearing aid hurts its sensitive ears.

“When her hearing aid goes off in the cornfield you have her in the shot but there was nothing behind her, so the audience did not understand that a creature came up behind her,” Form said.

But that scene worked incredibly well at the SXSW screening, when audience could see the terrifying creatures brought to CGI life by Industrial Light and Magic.

However, the uncertainty leading up to the night of that screening had everyone on edge. Though Paramount studio executives had seen cuts and liked what they saw, as Form put it, “1,200 strangers in a theater can tell you something very different.”

“If there was optimism it was self-created,” Fuller said of the lead-up to the SXSW screening. “Usually when you go into a screening like that you know what you have, this was totally blind. It was crazy. We were all very apprehensive. When the movie ended and the people started cheering I put my head on my wife's shoulder and cried because it was so fraught with tension and emotion. Because we had no idea.” 

Now the movie is riding high. Leading up to its opening weekend it was sporting a 100% Rotten Tomatoes score. And Form and Fuller now have some bragging rights on their horror colleague, Jason Blum, as “A Quite Place” topped the opening weekend box office of Blumhouse’s last two hit movies — “Get Out” ($33.3 million) and “Split” ($40 million).

“A Quiet Place” is the latest example that audiences will come out to theaters for more than just superhero movies and “Star Wars.” And though Platinum Dunes has no problem getting into the blockbuster game — it’s one of the production companies on the upcoming first Transformers spin-off movie, “Bumblebee” — the company is also striving to develop genre projects that are high in originality and will attract studios.

“It's a miracle that a major studio made a movie that is practically devoid of dialogue,” said Fuller, who wouldn’t address the possibility of a sequel to “A Quiet Place” (though with its big opening weekend number, it would be shocking if Paramount doesn’t want one). “But I also think studios recognize they have to make concepts that get people to leave their homes, so as producers it's incumbent upon us to find things that will get people to go watch a movie in a movie theater. So if you find a strong concept, I think they will always get behind it.”

"A Quiet Place" is currently playing in theaters.

NOW WATCH: A neuroscientist explains why reality may just be a hallucination

• New York City-based falafel chain Taïm is poised to take over Manhattan.
• Founders Einat Admony and Stefan Nafziger have partnered with an investment group spearheaded by Chipotle veterans to plot an expansion.  
• The chain recently opened its third location in New York, and two more are on the way.  

After more than a decade in business, beloved New York City-based falafel chain Taïm is starting to expand. 

Chef Einat Admony and Stefan Nafziger opened their first Taïm (pronounced "tah-eem," Hebrew for "tasty" or "delicious") restaurant in 2005. The fast-casual chain stays true to its founders' roots by specializing in Israeli food, serving falafel, hummus, and Israeli salad on pita or as a platter. It also serves a variety of salads, french fries, and other side dishes.

There are three Taïm restaurants operating in Manhattan, with an additional two in the works. The West Village location was the first to open, followed by outposts in Nolita and now, Midtown East, at the Urbanspace Food Hall. The Financial and Flatiron Districts will be the next neighborhoods to welcome the Israeli chain, with the Financial District location set to open in early July.

Eventually, Taïm will likely expand beyond New York and into other markets such as Washington, DC, according to Restaurant Hospitality. To aid in its expansion, the founders of Taïm have partnered with an investment group spearheaded by Chipotle vets Phil Petrilli and Bethany Strong.

We recently visited Taïm's second outpost in the Nolita neighborhood of New York City. Here's what it's like to eat there:

The Taïm I went to was in the Nolita neighborhood in NYC. Across the street was one of its top Mediterranean-food competitors, Cava.

It was packed when I arrived just after noon.

The menu had a few types of falafel that you can order on a pita or platter. It also had salads, fries, sides, and smoothies. Everything was generally priced around $8 to $12.

Do you want to stop drinking alcohol and cut all sugar, grains, beans, peanuts, and dairy from your plate for a month? Then the Whole30 diet is for you.

Created in 2009 by then husband-and-wife pair Melissa and Dallas Hartwig, the premise of the monthlong regime is that if you put only "good" things in your body you’ll feel better, reduce inflammation, and transform your relationship with food.

Melissa, a former heroin addict, came up with the plan after she left rehab, quit smoking, joined a gym, and started eating healthier. She shared what worked so well for her with the masses, and the Instagrammable hashtag #Whole30, which to date has spawned 3.4 million posts, was born.

Whole30 involves a lot of diet restriction and willpower, which means the diet may not be the right choice for everyone. In fact, it ranked near the bottom of the list of US News & World Report's 40 best diets of 2018.

Here's how it works.

SEE ALSO: I tried electric shock therapy —and it was one of the wildest experiences I've ever had in a workout

There are at least seven big no-no's on the Whole30 diet.

The first: absolutely no alcohol all 30 days. This includes cooking with wine. Whole30 is meant to be a kind of radical body cleanse, and for that reason the inventors also ask people to refrain from smoking during the 30 days of the fast.

Bread and whole grains are off limits.

Eating whole grains can be a great way to incorporate belly-filling fiber and satisfying protein into your diet, all while reducing inflammation. But forget about it if you're doing Whole30.

That includes quinoa.

Just about every kind of starch, bran, or germ you can think of is off limits. Gluten-free bread, buckwheat flour, amaranth, or rice? No, no, no, and no.

But potatoes, formerly banned from the diet, are OK for Whole30-ers now. (Still, no potato chips or french fries allowed.)

It's still early in the year, but the list of canceled TV shows is already piling up.

Networks haven't announced many cancellations yet, except for ABC, which canceled its freshman sitcom "The Mayor" and "Once Upon a Time," once a ratings hit. And in March, TNT announced the cancellation of its original series "The Librarians."

On the streaming side, things are a bit different. Amazon kicked off the year with a slew of cancellations, announcing the end of three quirky comedies, including the Golden Globe nominee "I Love Dick" and the comedian Tig Notaro's semi-autobiographical show, "One Mississippi." It canceled Golden Globe nominee "Mozart in the Jungle" in April, after four seasons. Also in April, Netflix canceled the 90s coming-of-age comedy, "Everything Sucks," which came to the streaming service in February. 

There are many more cancellations to come, especially since networks haven't announced the fate of their fall shows.

We'll update this list as more are announced.

Here are all the shows that have been canceled this year, including those from networks and Netflix:

With shows like "Jersey Shore," "Roseanne," and "Queer Eye" returning this year, TV reboots are having a moment.

The "Roseanne" reboot may have premiered to high numbers (over 18 million viewers) and positive response, but that doesn't mean all TV reboots strike the same success.

For every "Twin Peaks: The Return," there is a "24: Legacy" — meaning there are plenty of truly bad reboots that get greenlit and make it onto our television screens. 

Business Insider looked at 12 of the worst TV reboots ever. Some didn't last long, while others somehow found a longer life than their Rotten Tomatoes scores would suggest.

We ranked them from bad to worst based on those RT critic scores (we took the average of the available seasons) and broke any ties with audience scores on the review-aggregator site. 

The worst of the bunch even has the rare misfortune of having a 0% Rotten Tomatoes score.

Below are 12 of the worst TV reboots of all time, ranked by how bad they were:

Original series run ("24"): 2001-2010 on Fox

"If the story was half as compelling as an average Homeland season, perhaps audiences could overlook the political commentary. But there's little urgency driving the conventional TV action ... its stars' personalities are largely drowned out by exposition." — Ben Travers, Indiewire

Critic score: 53%

Audience score: 85%

Original series run: 1981-1989 on ABC

"I'll never watch this again. Dynasty reminds you of all the bad ways in which the world has changed. It's not niche or interesting to have a soap opera about people who are merely undeservedly loaded any more." — Hugo Rifkind, The Times (UK)

A new full-length trailer for "Solo: A Star Wars Story" dropped Sunday night, and it features plenty of new footage.

The trailer shows more of Alden Ehrenreich as the title character, a young Han Solo — a character made famous in the original "Star Wars" trilogy by Harrison Ford.

It also gives us more of Donald Glover as Lando Calrissian (who steals the show), and a better glimpse at the worlds and action audiences will witness during the movie (the Kessel Run, perhaps?). Also, there's probably a love interest for Chewbacca.

We've broken down the new trailer and highlighted its best moments and the questions it raises, from a sarcastic new droid to a look at Paul Bettany's villain.

"Solo" comes to theaters next month after a troubled production. Original directors Phil Lord and Chris Miller were fired over creative differences and replaced by veteran director Ron Howard, who, according to an actor in the film, made filming run a lot smoother.

Despite the obstacles, "Solo" not only kept its May 25 release date, but it's premiering at the Cannes Film Festival on May 15.

Below is our breakdown of the new "Solo: A Star Wars Story" trailer:

Han always shoots first.

It looks like Han Solo's shooting skills are going to be put to the test in this scene early in the trailer (and maybe early in the movie, since it doesn't look like any of other characters are with him yet). The trailer alludes to the idea that Han might be after these guys for revenge. Revenge for what?

Any time Donald Glover shows up is worth mentioning.

We can already tell that Donald Glover — who plays a young Lando Calrissian — is going to be a highlight in "Solo," and might even overshadow the title character. Glover steals the show in this new trailer.

"Or is it something else?"

"You're after something. Is it revenge? Money? Or is it something else?"

Emilia Clarke's character Qi'ra tells this to Han, and the voiceover for that last part is during this shot of Han and Chewbacca staring up at the Millennium Falcon. It's a nice signal that Han may be a smuggler, but in his heart, he's in it for the adventure more than vengeance or money.

• HBO programming chief Casey Bloys had some criticism for the runaway spending of his network's streaming rivals, Netflix and Amazon, in a new interview with The Hollywood Reporter.
• Bloys speculated that widespread, exorbitant TV spending could mean that the industry is "in a bubble."
• He said that his rivals' spending feels like "irrational exuberance," in a reference to Alan Greenspan's label for the dot-com bubble of the 1990s.

HBO programming chief Casey Bloys had a degree of criticism for the big spending of his network's streaming-based rivals, Netflix and Amazon, in a new interview with The Hollywood Reporter. 

In a conversation centered on the million-dollar salaries HBO is paying stars Nicole Kidman and Reese Witherspoon for a second season of its hit series "Big Little Lies," Bloys also discussed the record-breaking, nine-figure contracts Netflix has given to successful showrunners Ryan Murphy and Shonda Rhimes in the past year.

He said Netflix's runaway spending was emblematic of the fact that, in today's TV industry, "it's just a reality that doing a show will cost more."

Netflix has said it will spend roughly $8 billion on content this year, up from the $6 billion it spent in 2017, while HBO last year spent about $2 billion on content.

THR's Lacey Rose then asked, "At some point, there’s a ceiling, no?," regarding spending in TV. 

"A lot of people speculate about that. Are we in a bubble? Is there too much?" Bloys said. "It certainly does feel like, as Alan Greenspan called it [in reference to the dot-com bubble of the 1990s], irrational exuberance. But just like any market, nobody really knows when you're at the top."

When asked to comment specifically on the $1 billion that Amazon is expected to spend on a series adaption of "The Lord of the Rings," Bloys deflected and instead spoke to HBO's more selective strategy of "curating excellent content."

"[HBO CEO Richard Plepler] and I talk about that, too, [and it’s,] ‘Eyes on your own paper,’" Bloys said. "And it's true: we’ve got to stay focused on our goal, which is curating excellent content -- not ignoring the outside world because you can’t but also trying not to get too distracted by Amazon has this money or Apple has that money. Money is obviously very nice but it doesn't automatically mean quality. It's very hard to curate content and it matters how you engage with talent and how you treat them. And it's the game we've been playing for a long time. "

• Hartsfield-Jackson Atlanta International Airport is once again the busiest airport in the world.
• Nearly 104 million passengers traveled through ATL in 2017.
• Airports Council International compiled its list of the busiest airports in the world using data from 1,202 airports around the world.

Airports Council International (ACI) released its latest list of the busiest airports in the world. Once again, Hartsfield-Jackson Atlanta International Airport took the top spot with nearly 104 million passengers in 2017. Even though total traffic figures at ATL fell by 0.3%, it was enough to hold off Beijing Capital to retain the crown.

According to ACI, global passenger figures increased 6.6% in 2017 while total aircraft movements went up by 2.4%.

"The surge in cargo volumes and passenger numbers across many of the world’s airports is a testament to heightened business and consumer confidence, at least in the short term," ACI World director general Angela Gittens said in a statement. "The world’s airports continue to be a vital link in the economic multiplier effect that aviation provides and the role it plays as an enabler for global commerce is growing."

The trade group compiled its list using data from 1,202 airports from around the world. 

The top 20 airports accounted 17% of the 1.5 billion passengers who passed through airports around the world in 2017.

• "A Quiet Place" had one test screening, and audiences were very confused while watching it.
• According to the producers behind the movie, Platinum Dunes' Bradley Fuller and Andrew Form, the CGI wasn't ready yet to have the scary monsters in the screening.
• In fact, some of the footage the audience saw was director John Krasinski in a motion-capture suit playing a monster.

Warning: Minor spoiler below if you haven't seen "A Quiet Place."

John Krasinski's latest directing effort, "A Quiet Place," scored a huge $50 million opening weekend for Paramount over the weekend thanks to its frightening premise: monsters that kill anything that makes a sound.

But how would the movie be if the monsters never appeared on-screen? That's what a test-screening audience had to endure.

According to the Platinum Dunes heads Andrew Form and Bradley Fuller, the producers behind the hit movie, the test screening of "A Quiet Place" was more excruciating than usual because the computer-generated monsters from the special-effects house Industrial Light & Magic weren't ready.

In their place were basic plate graphics of the monsters or footage in which someone dressed in a motion-capture suit would perform a monster's movements in the scene.

In fact, Krasinski himself played the monster in some scenes.

"Sometimes John was in the motion-capture suit playing the monster," Form said. "In that basement scene he was the creature down there."

Form and Fuller are no strangers to having to show a test screening with little to no computer-generated imagery. Platinum Dunes also produces Paramount's Teenage Mutant Ninja Turtle movies, and they said it's always weird to test those movies without the CGI turtles finished. But for "A Quiet Place," they acknowledged it was a little more confusing for audiences to understand what was going on.

Take, for instance, the pinnacle scene in the movie in which one of the monsters runs away from Regan (Millicent Simmonds) because her hearing aid hurts its sensitive ears.

"When her hearing aid goes off in the cornfield, you have her in the shot but there was nothing behind her, so the audience did not understand that a creature came up behind her," Form said.

So the movie went into its world premiere at the sci-fi/horror-loving South by Southwest Film Festival a month ago coming off a test screening that confused audiences and most likely wasn't very scary because there wasn't much monster footage.

Thankfully, ILM delivered the monster CGI in time and the audience loved the movie. The movie eventually received a 100% rating on the reviews aggregator Rotten Tomatoes before the movie's theatrical release.

"If there was optimism, it was self-created," Fuller said of the lead-up to the SXSW screening. "Usually when you go into a screening like that you know what you have — this was totally blind. It was crazy. We were all very apprehensive. When the movie ended and the people started cheering I put my head on my wife's shoulder and cried because it was so fraught with tension and emotion. Because we had no idea."

NOW WATCH: Facebook can still track you even if you delete your account — here's how to stop it

• Americans tip 16.4% of the check, on average, according to a study from Square.
• But people in states that vote for Republican candidates leave bigger tips on average than in Democratic-voting states.
• High-income blue states like California and Massachusetts tip below the national average.

In this hyper-partisan environment, it seems like nothing avoids the political conversation — and tipping is no different.

States that have recently voted more Republican have also tended to have higher average tips than those in more liberal states. 

Americans tip 16.4% of a check, on average, according to a study from Square that measured credit and debit card transactions from over two million vendors in July 2017 to find how much people tip in each US state.

Business Insider compared the average tip in every state to the Cook Partisan Voter Index (PVI), which uses the results of the 2012 and 2016 presidential elections to determine how red or blue the state is, compared to the national average.

On the graph, a state with a PVI of Republican +10 shows that the state is on average 10% more likely to vote Republican than the nation as a whole. A score of -10 is equivalent to a 10% margin for Democrats. The relationship between PVI and tipping has a R-squared value of .506, meaning that there is a moderate correlation between a state's election results and its propensity to tip servers.

It's worth noting that Square's data looked at state populations as a whole, and that this analysis doesn't tell us about how individual voters and tippers behave. That is, even though red states tended to have higher average tips, we can't say whether or not Republican voters individually tip better than Democratic voters.

People also tip differently depending on where they live. According to Square's research, five of the ten states that tip less than 16% are in the Northeast.

The state with the lowest tip average, Hawaii, paid 14.8% of the check, while the place with the highest tip average, Idaho, paid out 17.4%.

Below, see the average tip amount for every state, as well as where it falls on the partisan voter index.

• Friends are important for health and happiness — but they don't just materialize out of thin air.
• A new study suggests it takes 50 hours before an acquaintance becomes a casual friend; 90 before they become a friend; and more than 200 before they become a best friend.
• During that time, conversations focus on catching up and meaningful issues — not small talk.

Teaching someone how to make friends is like teaching someone how to ride a bike — you say this, you put your foot here, do you get it now?

That is to say, it's all kind of intuitive: When it's working, you'll know.

But a new scientific paper, which was published in the Journal of Social and Personal Relationships and cited on Psychology Today, provides some more concrete direction for students in the school of friend-making.

According to the paper, you need to spend about 50 hours with someone before they go from an acquaintance to a casual friend, about 90 hours before they go from there to friend, and more than 200 hours before they become a best friend.

The research was led by Jeffrey A. Hall, a communications professor at the University of Kansas. Hall ran two studies: one with 355 adults who'd recently moved to a new place and one with 112 college first-years.

In the first study, Hall asked participants to think of someone new they'd met since moving. Participants described how much time they spent together, how close they felt to that person, and where the person fell on a scale from acquaintance to best friend.

In the second study, Hall asked participants to think of two new acquaintances and then followed up with the students twice over the first nine weeks of the academic year. At each point, students indicated how much time they'd spent with the acquaintances and how they characterized their friendship.

Results showed that the more time people spent together, the closer they were. But it wasn't simply occupying the same physical space that seemed to cinch the deal.

If you're trying to make a friend, engaging in small talk won't cut it

In fact, Hall found that spending a lot of time together at work or at school predicted less friendship closeness. On the other hand,  "hanging out" together, watching TV or playing games, outside these realms predicted greater friendship closeness.

The content of people's conversations turned out to matter a lot, too. People who engaged in a lot of small talk wound up getting less close over time. By contrast, people who spoke more substantively: "catching up, checking in, joking around, and meaningful conversation."

That finding jibes with other research on the importance of self-disclosure in the early stages of friendship: Revealing details about your life (slowly and selectively) can help strengthen the bond between you and another person.

It's worth noting here that the link between how much time people spent together and how close they became is correlational. It's possible that people were inclined to hang out because they clicked — not that they clicked because they hung out.

Also worth noting: Some people may simply be better equipped to make friends than others. Research suggests that people who are agreeable, open to experience, and conscientious are more likely to experience "friendship chemistry," or an instant connection.

Ultimately, this research suggests that making a friend means making a substantial investment of time and energy. Neither of those are unlimited resources, which may be why most of us can count the number of close pals we have on one hand.

NOW WATCH: Here's why we give better advice to our friends than we give to ourselves

• Shooting drills and other tactical exercises are sometimes held in the workplace to prepare employees for potential violence. 
• But security expert Laurence Barton said told Business Insider that employers should instead encourage workers to trust their instincts and remain "situationally aware" on the job.
• Getting people to trust their instincts during an emergency, though, can be particularly tricky at work because people are afraid of appearing paranoid or overly jumpy in front of their coworkers and bosses.
• Barton said it's always better to be safe than sorry.

Shooting drills and other tactical exercises held in the workplace are meant to help employees prepare for potential violent threats.

But, according to threat management and workplace violence expert Dr. Laurence Barton, such drills and exercises should take a backseat to something far more innate.

For Barton, encouraging people to listen to their instincts is key.

He told Business Insider that employers need to adopt flexible emergency plans and policies that empower employees to trust their intuition, rather than static ones.

For example, instead of instructing everyone to evacuate the building and meet up at a neighboring McDonald's, Barton said to order employees to clear out in the event of an emergency and keep moving until they feel safe enough to stop.

That's because a static plan can endanger lives, in the event of unforeseen circumstances like a second perpetrator or an attacker who's aware of an office's contingency plans. A flexible plan should encourage individuals to take swift action and do whatever they need to do to make themselves safe.

This sort of instinct-driven action is key to dealing with any kind of workplace emergency, Barton said. But it's especially hard for people to trust their guts at work, since people are often lulled into a false sense of security there.

"At work, we turn our intuitions down," Barton told Business Insider. "That doesn't mean that we turn them off completely, but we turn it way, way, down. We have our coffee, we have the Outlook schedule for the day. We know who we're going to say 'hello' to. We've got our meeting schedules."

He said people at work need to boost their "situational awareness" in order to better deal with sudden danger.

So what does a more-situationally-aware person look like? Barton gave the example of a shopper heading to Target at night.

"The reality is if some sketchy character starts to approach me in the parking lot and I don't feel safe, I'm either going to go back into my car and lock it or I'm going to run into the store," he said. "I'm going to hustle. I'm not going to stand there and become a victim."

In other words, in most cases, we don't second guess ourselves when confronted with a potential threat in a dimly lit parking lot.

But in the office, people often experience a sense of disbelief and paralysis when dangers do arise. Barton said he's interviewed numerous survivors of violent incidents in the workplace. Many describe freezing up and not taking the opportunity to flee.

"They'll say, 'I can't believe that I stayed there. I knew there were gunshots, but I had such a sense of disbelief,'" he said. "Or, 'I thought someone was addressing it.' Or, 'I thought maybe it was firecrackers.' You just want to believe it's not what it is."

A situationally-aware person would identify a potential threat such as loud popping sounds or the presence of a disgruntled former coworker. They would then trust their instincts and take decisive action to deal with said danger — say, evacuating the building or hiding and calling 911.

Barton said many people might worry about appearing paranoid or overly jumpy at work. No one wants to be the person who runs out of the building because somebody's car exhaust backfired in the parking lot.

But while he said he doesn't advocate that people become paranoid, it's always better to be safe.

"Don't make any assumptions," Barton said. "I would rather that you move, get to the stairs, and get out of the building. I'd take that embarrassment anytime over being shot in the leg. Why would you risk that? And what would you tell your children?"

• How airplane food is made can depend on the airline.
• For Singapore Airlines, they contract an airline catering firm called Gate Gourmet in Switzerland to produce more than 50,000 meals a day.
• Some of the most fascinating details and secrets from inside Singapore Airline's food facility include that the kitchen has only five hours to prepare 1,500 meals for a full flight, and one mistake could waste 33 pounds of food at a time.

Airplane food has a reputation for not being particularly great. But when you fly Singapore Airlines, there's a really slim chance you'll get stuck with a bad meal.

Singapore Airlines rakes in tons of awards for being one of the best airlines in the world, and one of the chief considerations for such awards is the food — even in economy class. The airline's food and wine variety and quality stand out among its competitors'.

According to the Netflix documentary series"Mega Food," Singapore Airlines, which was the first airline to introduce in-flight entertainment and food options, serves about 50,000 meals a day. On its A380 flight, passengers have more than 50 meal choices. And food served on board is never frozen and almost always made from scratch. 

So how does Singapore Airlines do it?

The airline contracts with Gate Gourmet, the world's largest independent airline catering company, which is headquartered on the grounds of Zürich Airport in Switzerland and has 122 kitchens serving five continents and making 250 million meals a year.

Gate Gourmet's staff, including regional executive chef Oliver Fischer, took "Mega Food" through their facility to show how airplane food is made for Singapore Airlines.

Here are some of the most fascinating details and secrets from inside the food facility where Singapore Airline's meals are made.

To ensure cultural authenticity, recipes include precise measurements for spices and ingredients. One mistake or deviation from the recipe could result in 33 pounds of food wasted at a time.

The most complex foods for the kitchen to make, Fisher said, are ethnic foods where there is also a religious component restricting certain ingredients. "You need a lot of understanding of culture," he said.

• NFL cheerleaders must follow strict rules to keep their jobs, according to a report from The New York Times.

• Some teams require cheerleaders to maintain a strict body weight, cover up tattoos and body piercings, and forego wearing sweatpants in public.

• One New Orleans Saints cheerleader was even sacked over an Instagram post, The New York Times reported, prompting a discrimination case.

NFL cheerleaders must adhere to a number of intense rules if they want to keep their jobs, according to a recent report from The New York Times.

These directives don't just pertain to cheerleaders' workplace conduct, either. The mandates dictate how cheerleaders can behave when they're off the clock, too.

Specific guidelines vary from team to team, but it's not the first time the treatment of NFL cheerleaders has been the subject of a controversy.

Some cheerleaders reportedly earned less than $1,000 a year in 2016, according to USA Today, and Time reports multiple lawsuits have been filed that allege that teams paid below the minimum wage. And now some are arguing are that the rules are sexist and that the NFL cheerleaders in general are exploited. A former New Orleans Saints cheerleader, who was fired after she posted a photo of herself in a one-piece outfit on Instagram, has even filed a discrimination case against the team, The New York Times reported.

Here's a look at some of the rules many NFL cheerleaders must abide by:

• Urban Outfitters CEO Richard Hayne said in a recent call with investors that fashion is now "fashionable again."
• The company reported strong fourth-quarter results, driven by a demand for new styles in bottoms. 
• Hayne said that the "fashion rut" of skinny jeans and yoga pants is over. Some analysts have backed this up and said that athleisure, the dominant trend in apparel for the past decade, is fading out of popularity.

Fashion is undergoing a major shift. Athleisure may finally be on the way out after years of dominating the apparel business, and it's being replaced by more fashionable denim wear. 

"Fashion, well, it's fashionable again," Urban Outfitters CEO Richard Hayne said in a call with investors in March, explaining that strong growth in the quarter was driven by demand for new styles in its "bottoms" business. Same-store sales were up 4% across all of its brands, including Urban Outfitters, Anthropologie, and Free People, during the quarter.

"Demand for new fashion has surged," he said, adding that apparel has been stuck in a "fashion rut" defined by skinny jeans and yoga pants for the past few years.

Athleisure has been a dominant trend. Between 2011 and 2016, the market for athletic wear grew to be 30% of the total clothing and footwear industry, increasing an impressive 7% a year compared to the 1% growth of the apparel sector in general, according to Wells Fargo analysts. The trend started with athletic brands such as Lululemon, Under Armour, and Nike, but eventually, even more traditional clothing stores such as Gap, J. Crew, and Forever 21 followed suit in the hope of boosting their own sales.

But some analysts now say that it's hit its peak, partly because the market is overcrowded with options.

In 2017, growth in this category showed some signs of slowing. US activewear sales totaled $48 billion last year, which was a more modest 2% rise from 2016 compared to previous years, according to The NPD Group.

Meanwhile, new styles of denim, such as high-waisted pants, are captivating the hearts of American shoppers.

"The last time we had a change, I think, was around 2006-2007," Hayne said in the earnings call.

A resurgence in '90s styles — which may well have kicked off in vintage stores as trendy shoppers showed that they were prepared to spend hundreds of dollars on a pair of vintage Levi's — is taking off in mainstream fashion. Levi's has already latched on to this and created a new collection of limited-edition jeans from the '60s, '70s, and '80s, known as Levi's Authorized Vintage, which are sold for $300 a pair.

"We were sitting on an aged icon," James "JC" Curleigh, president of Levi's, told The Wall Street Journal in 2017.

The company reported an 8% sales increase in 2017, which was the highest growth rate in a decade.

The same is true of Calvin Klein, which has relaunched its archive collection to capitalize on the vintage trend. 

In its most recent earnings, reported at the end of March, Calvin Klein and Tommy Hilfiger parent company PVH said that jeans showed "incredible improvement" in 2017. In particular, Calvin Klein jeans showed "tremendous strength and outsized growth above our average order book growth," CEO Manny Chirico said in a call with investors.

But Urban Outfitters' CEO says the company is ahead of the curve with its wide-legged, high-waisted pants, and he believes it's well-positioned to benefit from this trend for several years. 

"Most of the benefit to us, since we consider ourselves a fashion leader, accrues in the first half of that period before there is a widespread adoption and lots of folks copy," Hayne said.

He added: "And so, I would expect it to benefit us for anywhere from three to, six or seven years."

• Tony Robbins, world-renowned performance coach, has apologized for comments he made about the #MeToo movement at an event in March.
• Robbins told an audience member at the event that women use the movement to "get significance and certainty by attacking and destroying someone else."
• NowThis tweeted a clip of the event that went viral.
• Tarana Burke, founder of the #MeToo movement said Robbins' comments were especially damaging because of his tremendous influence.

World-renowned performance coach Tony Robbins has apologized for remarks he made in March, about how women use the #MeToo movement to "get significance."

Robbins posted the apology on Facebook and linked to the statement on Twitter. It read, in part: "I apologize for suggesting anything other than my profound admiration for the #MeToo movement. Let me clearly say, I agree with the goals of the #MeToo movement and its founding message of  'empowerment through empathy,'  which makes it a beautiful force for good."

Robbins made his original remarks on March 15, at "Unleash the Power Within," a three-and-a-half day seminar that took place in San Jose, California. After Robbins praised Steve Wynn, the former CEO and chairman of Wynn Resorts who was accused of sexual harassment, an audience member named Nanine McCool raised her hand to challenge him.

McCool's interaction with Robbins was filmed by activist and musician Butterscotch, who posted the roughly 11-minute video on YouTube.

The video didn't get much attention until Friday, when NowThis tweeted a one-and-a-half minute clip from the video, which has since been viewed more than 5 million times.

"If you use the #MeToo movement to try to get significance and certainty by attacking and destroying someone else, you haven't grown an ounce," Robbins told McCool. "All you've basically done is used a drug called significance to make yourself feel good."

McCool told Robbins, "I think you do the whole movement a disservice by characterizing it that way." Audience members cheered and clapped in the background.

Robbins invited McCool, who later told Refinery29 that she was sexually abused as a child, to come closer to him and put out her fist. Then he proceeded to push his hand against hers and asked her why she was pushing back. (This is an exercise Robbins does often with clients.)

"When you push someone else, it doesn't make you more safe," Robbins told McCool. "It just makes them angry."

Robbins went on to share an anecdote about a man he knows who was worried about hiring an attractive woman: "He knew, 'I can't have her around because it's too big a risk,' and he hired somebody else."

On Saturday, the founder of the #MeToo movement, Tarana Burke, tweeted that Tony Robbins' team had reached out to her to do "damage control" and provide context for Robbins' comments.

In one of a series of follow-up tweets, Burke wrote: "This moment is so damaging especially with how influential @TonyRobbins is. We have a hard enough time trying to shift the narrative about what this movement really is and he stands in front of thousands of his followers and completely misrepresents the @MeTooMVMT"

Robbins' public apology mentioned that he personally was a victim of abuse as a child. Last year, Robbins told Business Insider that his mother physically and emotionally abused him.

 "Sometimes, the teacher has to become the student," Robbins wrote in the apology, "and it is clear that I still have much to learn."

NOW WATCH: Here's why we give better advice to our friends than we give to ourselves

• Tuesday is Equal Pay Day and it's traditional to wear red to work in solidarity.
• Tech companies, for all their hand-wringing about attracting more women to the industry, still don't pay women equally to men, new research finds.
• A documentary called Chasing Grace by a former Linux Foundation exec is sharing women's stories about discovering they were getting paid less.

Imagine coming home from your favorite grocery store and discovering your neighbor shops at the same store, buys the same items — and still pays about 20% less than you do. And when you complain, you're told that there's nothing anyone can do, that it's just the way things are for people like you, despite any laws to the contrary. 

How would you feel about this store? Somewhere between disillusioned and duped? Would you still shop there? Think about this analogy as you consider how women are still paid less than men, even for the same work.

Tuesday is Equal Pay day, intended to to bring awareness to the pay gap.

A new report from job-hunting site Hired found that in the tech industry, the gap begins at the get-go. Hired found that 63% of the time, men are offered higher salaries than women for the same role at the same tech company. On average, these companies offer women 4% less than men for the same role, with some offering women up to 45% less.

If there's some good news in Hired's report it's this: San Francisco, a major tech hub, has the smallest pay gap. That may be influenced by San Francisco's largest tech employer, Salesforce. The cloud computing company has adjusted its payroll twice now, raising women's salaries to keep them equal.

The second time occurred thanks to all the companies it acquired, CEO Mark Benioff recently told me during an on stage interview at the company's annual developer's conference.

Chasing Grace

The pay gap is one reason why, after years of covering all the problems women in tech face in their careers, I have decided to become an advisor to something called The Chasing Grace Project, a video documentary series about women in tech that I will provide editorial advice to. (Disclosure: this is a fully volunteer gig, with no compensation of any kind for me — no pay, no perks, no reimbursements, no equity. The project does have some corporate sponsors including the Linux Foundation, Cloud Foundry and Intel, but is independent of them.)

Chasing Grace (named after Grace Hopper, the computer programming pioneer) is a new documentary series shedding light on the struggles of real women and offering as many answers as it can.

It's a labor of love by Jennifer Cloer, co-founder of  Wicked Flicks Productions. Cloer is well-known in the tech industry for her six years running communications for the Linux Foundation, the granddaddy of open source foundations. And open source, despite its kumbaya work ethic, is a decidedly bro club: 97% male and notoriously hostile, a recent GitHub survey found.

The initial episode of Chasing Grace dives into the pay gap and how an infuriatingly unfair system causes an emotional and economic toll.

It documents the stories of several women in tech, including engineers, business people and founders. It shows how they discovered their male peers were getting paid far more than them and how that information threatened to derail their careers.

For instance, in one case the company gave a job offer to an entry-level man that was more money than it was paying a senior woman who had spent years building the company.

One of the women interviewed explained the solution simply: "Don't lowball her. Give her the fair pay. You know what it is."

Helping or hurting?

There are those who argue that business shouldn't pay people equally based on some people's idea of morality or fairness. Doing such a thing would raise costs and hurt the company. 

The counter argument is that by basing pay on what people look like, rather than what they do, a company is hurting itself. Messing with people's pay creates resentment among employees and drives away top people.

Some researchers say there's a societal benefit as well.

Across industries, closing the pay gap could add more than $512 billion to the U.S. economy and cut poverty almost in half, according to research from theInstitute for Women’s Policy. Doing that would reduce the need for taxpayer-based public assistance.

Even for women in tech who are in the higher-tier of professional compensation, and nowhere near the poverty line, disparities in pay can take a long-term toll on lives and families, says Clair Wasserman, co-founder of Ladies Get Paid, a networking group for women.

"White women are losing about $500,000 over the course of their lifetime over the course of their career. Women of color are losing $1 million," Wasserman says in Chasing Grace episode one.

That's the cost of paying off a house.

So on Tuesday, if you are a woman, or you are married to a woman, or you have daughters, mothers, aunts, sisters or female cousins, then you may be motivated to show your support for Equal Pay Day by wearing red to work. Tweeting your support to #equalpayday is a nice gesture, too.

Obviously, outfits and tweets won't solve the problem but bringing the discussion to work is a place to begin.

The Chasing Grace Project will also tackle other issues concerning women in tech. It is currently available only to private screenings.  Cloer is hoping to negotiate a national distribution deal and will eventually release the project online. 

Here's a clip:
