The world's busiest airports see anywhere from 55 to 100 million passengers pass through in a year.

When you deal with even a fraction of these busy travellers from around the world on a daily basis, you can expect to encounter some bizarre human behavior.

As one flight attendant told Business Insider, you really get to see it all: "Never say never. Weirdness will always outdo itself if you challenge it."

Still, there are some things that would stun even the most seasoned airline employee.

Here are some of the most trying work conditions airline workers including flight attendants, gate agents, ticket agents, and other airport customer service reps have been subjected to:

"Yoga people trying to use our galley as their personal studio" is one of the weirdest things a flight attendant with four years of experience told Business Insider they've seen.

Strange announcement requests

A flight attendant with three years of experience told Business Insider that she's gotten her fair share of strange announcement requests.

"One gentleman was angry, and he asked me if I could make an announcement over the PA. When I asked him what he wanted me to announce, he said, 'Somebody in this vicinity is passing gas, and I need them to stop,'" she said.

Another passenger asked her to make an announcement asking a neighboring passenger to give up the armrest.

Celebrity encounters

"The weirdest thing was hosting Michael Jackson in our employee break room so he didn't have to sit in the terminal," an anonymous airline customer service agent told Business Insider.

While for years Chipotle denied customers' demands that the chain add queso to the menu, the Tex-Mex chain is now singing a different tune. 

Queso could be available at Chipotle locations across the US in just two weeks. In a note to clients on Tuesday, Credit Suisse analyst Jason West predicted a September 12 national roll-out.

While Chipotle has not yet formally announced a national queso launch date, the chain debuted the cheesy dip in its New York City test kitchen in July. Chipotle began serving queso at roughly 350 restaurants in California and Colorado in August.

Chipotle didn't immediately respond to Business Insider's request for comment, but executives have previously said that queso could be added to menus nationally as soon as mid-September. 

Business Insider tried the queso at Chipotle's test kitchen, which also serves other test items, including new salads and margaritas. Here's what the chain's all-natural take on the cheesy dip is like.

The test kitchen, called Chipotle Next Kitchen, is on the corner of Sixth Avenue and 13th Street in Manhattan.

Wandering in, you'd think it's just a run-of-the-mill Chipotle, complete with the standard fast-casual decor and the lunchtime rush.

But, this location was the first in the world to add queso to the menu.

London-based psychiatrist Ben Sessa sometimes feels like a doctor at a nursing home.

"Psychiatry is a desperate place to live sometimes; it feels like a palliative care industry," Sessa said at a conference in London this July on the science of psychedelics. "We've almost given up hope that we can actually cure [many of our patients] and turn it around."

That's why he and several other scientists have turned a hopeful eye in recent years toward psychedelics, drugs that have been around for decades but have never been explored — at least legally — for medical use.

One of those drugs is MDMA, or ecstasy. The group leading the charge to get MDMA approved for medical use passed a major hurdle after the US Food and Drug Administration granted it a special designation that could fast-track its approval to treat PTSD.

Breakthrough therapy

The group behind the new research is the Multidisciplinary Association for Psychedelic Studies (MAPS), a nonprofit organization that is leading much of the research into psychedelics and mental illness in the US. MAPS' founder, Rick Doblin, said at the London conference that he believed MDMA was the "most likely" psychedelic to be adopted by psychiatric and psychotherapy professionals.

"MDMA is the most gentle of all the psychedelics," Doblin said.

Part of the premise of granting a treatment "breakthrough therapy" designation involves recognizing that it could have a meaningful advantage over existing treatments. As of August 27, MDMA has been granted this designation, meaning that it moves toward the final phase of medical trials that could one day lead to possible prescription use of the drug to treat PTSD.

A resurgence in interest surrounding psychedelics

The past year has seen a blossoming interest in exploring the use of psychedelics like ayahuasca and magic mushrooms for their potential to treat mental illnesses including depression and anxiety. Early studies suggest that the drugs reduce symptoms of both disorders by increasing the brain's connectivity in novel ways.

Psychedelic-based treatments "offer an opportunity to dig down and get to the heart of the problems that drive long term mental illness in a much more effective way than our current model, which is take daily medications to mask the symptoms and stay just-about level without digging down," Sessa said.

It's a source of hope to many people struck by conditions like anxiety and depression — especially those who haven't responded to traditional treatments like talk therapy and antidepressants.

Clark Martin, a cancer patient who participated in a medical trial of psilocybin (the active ingredient in magic mushrooms) for depression, said his experience was overwhelmingly positive. "With the psilocybin, you get an appreciation — it's out of time — of well-being, of simply being alive and a witness to life and to everything and to the mystery itself," Martin told Business Insider in January.

MDMA is different from magic mushrooms in many ways.

Known as ecstasy or "Molly," MDMA was created by pharmaceutical company Merck in 1912 and is currently considered an illegal substance with no medical benefit and a high potential for abuse. The drug is both a stimulant and a psychedelic, meaning it has both energy-raising and hallucinogenic properties, and it's been known to be dangerous when used without medical supervision because it raises body temperature and blood pressure. In the brain, MDMA amps up the activity of chemical messengers involved in mood regulation.

Yet researchers who study it say that these same characteristics could make it an ideal treatment for some types of mental illness. One arm of Doblin's research involves studying MDMA in veterans with PTSD in a setting which combines the drug with traditional talk therapy. In three of the sessions, patients are given the drug or a placebo and talk therapy; in another 12 sessions, they are given talk therapy alone.

Together, the two treatments could help produce faster and more measurable results, according to people involved in the research.

"Psychotherapy is painful, it's slow, it's fits and starts, you start to get to something important and then the patient disappears for a month at a time; they're very defended about getting down to it," said New York-based psychiatrist Julie Holland at the London conference. Holland is also the medical monitor for the MAPS study of MDMA for PTSD in veterans.

"MDMA-assisted psychotherapy allows the patient to be more sort of open to the process. It is a less painful process; MDMA can act as a catalyst to make the therapy go faster, be more efficient, be deeper, get to that malignant thing that needs to be taken out and examined in a more sort of peaceful environment with more acceptance," Holland said.

Researchers are hopeful that the new FDA designation will help them in their quest to provide relief to people who haven't benefited from traditional approaches.

"We need some new tools," said Sessa. "What psychedelic psychotherapy offers is really something quite unique."

• Beyoncé and Jay Z purchased a Bel Air estate for $88 million.
• They put 40% down and financed the rest with a $52.8 million mortgage from Goldman Sachs.
• With historically low mortgage rates, taking out a loan allows them to put their cash to better use.

Billion-dollar power couple Beyoncé and Jay Z have finally put down roots in Los Angeles.

The entertainment moguls recently bought a two-acre hillside estate in Bel-Air for $88 million, making it the sixth-priciest home purchase in the history of Los Angeles.

In addition to 30,000 square feet of living space housed in six glass-walled structures, the ultra-modern property has four outdoor pools, a spa and wellness center, a full-sized basketball court, and a 15-car garage.

Despite holding Forbes' title of the highest-paid celebrity couple in the world with a combined fortune of $1.16 billion, Beyoncé and Jay Z took out an eye-popping $52.8 million mortgage from Goldman Sachs for the purchase, the Los Angeles Times first reported.

That leaves the couple with a huge monthly payment of $149,600, according to the loan document, which is public record. The national median home value, for comparison, is $200,700.

Keeping their mounds of cash liquid could be a smart business decision. For starters, it helps to maintain their lavish lifestyle. But it could also allow them to continue investing heavily in tech companies, presumably earning returns greater than the amount of interest they'll pay, considering mortgage rates are still historically low in the US.

"Depending on how their portfolio looks — what they've invested in — I think there could be a huge benefit [to Beyoncé and Jay Z], it gives them flexibility, and they could pay the mortgage off any time," Robert Cohan, managing director at Carlyle Financial in Los Angeles, told Business Insider.

Based on mortgage applications for new home purchases in July from the Mortgage Bankers Association, the average American applied for a loan of $329,483. At 4% interest over 30 years, that's a monthly payment of $1,573. Beyoncé and Jay Z will be paying about 95 times as much for their new abode.

Cohan said the Carters likely had a prior relationship with Goldman Sachs, making it easier to secure the massive loan at a low interest rate.

"In regards to a mortgage this size — $15 million and up — you get into a position where a lender will only look at a mortgage this size if there is a relationship there, they won't look at it on a transaction basis," Cohan said.

The couple put down 40% of the purchase price — $35.2 million — in cash, and financed the mortgage through two separate trusts, public record shows. Their loan is a five-year ARM with an initial rate of 3.4%, meaning the rate will stay the same for the first five years, and then adjust annually based on Libor, a benchmark rate used by the world's leading banks. Until then, they'll be making interest-only payments.

In Los Angeles, and a handful of other pricey markets across the country, jumbo mortgages are issued for loans greater than $636,150. Supersized mortgages are the norm in Bel Air, the ritzy LA neighborhood the Carters will soon call home, where the median home value is $3.25 million, according to Zillow.

For a homebuyer looking to secure a jumbo mortgage, at least two years of tax documentation proving steady income is required, as well as a credit score above 720, a favorable debt-to-income ratio, and enough cash in the bank to cover a year of payments. Cohan said Beyoncé and Jay Z may have had to provide more documents as proof of cash flow, if the bank didn't already manage their money.

Ultimately, while there's some risk associated with lending a mortgage this size, he said, the potential benefit to the bank is high if Beyoncé and Jay Z park their other assets there as well.

"Large financial institutions — Morgan Stanley, Goldman Sachs — are fighting for these types of clients to manage their money where they can have access to this opportunity," Cohan said.

Once upon a time, Nike's Jordan brand was crushing it. It seemed that everyone wanted the brand's new releases, which sold out instantly amid overwhelming demand.

But times have apparently changed. In a note about Foot Locker, Morgan Stanley analysts wrote that Jordan's performance was "much worse than expected."

In a call with investors on August 18, Foot Locker CEO Dick Johnson said "the sell-throughs of certain Jordan models slowed considerably compared to historical rates" in North America.

Jordan has been struggling amid an industry-wide downturn in sales of basketball sneakers. The trends are now favoring low-top sneakers like the Adidas Superstar, as the chunkier looks of basketball shoes don't quite fit in with skinny jeans and joggers.

To remedy the issue of falling sales amid the trend shift, Nike has been releasing more and more Jordan shoes, including re-releases of vintage styles. Now, when Jordan shoes are released, they do not always sell out instantly. That has eroded the brand value of Jordan, which has long-term implications for the company, according to Josh Luber, CEO of sneaker resale platform StockX.

Morgan Stanley worries that Nike has either "misdiagnosed" Jordan's problem or "underappreciated the gravity of the situation."

A wind of change may be blowing now, however, as UBS analysts say that denim — and the basketball styles that go along with it — may be on the upswing soon.

Temperatures reached near triple-digits in Black Rock City, Nevada, on Monday — where the music and arts festival Burning Man is underway — but it didn't stop winter from coming.

Attendees at Burning Man were treated to a screening of the "Game of Thrones" season seven finale the day after it aired, after festival-goers made pleas across the internet for a way to watch it.

The annual counterculture festival takes place in a remote swath of desert, where high-speed internet and cable TV are hard to come by.

Reddit user jaxdesignsaid their theme camp, Beans Beans the Musical Camp, projected the highly anticipated finale on a screen inside the camp, shortly after sundown on Monday. 

"It's real. Beans beans the musical camp at 9:30 and E. our setup is really amazing, projector with huge screen, massive speakers. See you then," jaxdesign posted earlier in the day.

"Game of Thrones" fans rejoiced. "Thank you for your service," one Redditor wrote.

When burners first caught wind that the season finale fell on day three of Burning Man, some diehard fans of the show took to the internet to express their heartbreak.

"I hate to be this guy but I really don't want the episode spoiled for me while I'm on the playa," reddit user Cassaroll168 wrote a month before the event.

People who stayed behind while their friends went to Burning Man had a laugh.

Grilled chicken: the timid, humdrum sibling of fried chicken.

While nowhere near as glamorous or greasy as its crispy companion, grilled chicken is starting to increase in popularity as it rides the wave of health-conscious dining.

Most major fast-food chains now offer grilled-chicken options, from sandwiches to nuggets.

But seared chicken isn't masked by a delicious fried coating, so it has to be good to pass muster.

We tried grilled-chicken sandwiches from seven major fast-food chains — Burger King, Bojangles', Chick-fil-A, Hardee's, McDonald's, Wendy's, and Zaxby's — to find out which is best.

SEE ALSO: We visited the controversial, award-winning Trump Winery in Charlottesville— and it was completely different from what we expected

8. Burger King Tendergrill

According to Burger King's menu, this chicken is marinated and seasoned with "pepper and herbs" — yet in reality, it tastes of utter nothing. The bun is weak, underwhelming, and prone to flattening. And with the sandwich coming in at 470 calories — the highest of any on this list by a long shot — its nutritional value is dubious at best. 

This is a chicken sandwich in the midst of an existential crisis. Is it meant to be an enjoyable, flavorful item or merely a bland vehicle for protein delivery? The chicken itself is dry, stringy, and tough. The lettuce and tomato are pallid, and the mayonnaise oversteps its boundaries in every bite. This sandwich leaves one in tangy despair.

7. Bojangles' Grilled Chicken Sandwich

The grilled chicken from Bojangles' is, in a word: disappointing. The chicken breast is flavorless and dry, which makes little sense considering how over-laden with mayonnaise the sandwich is. The bun sops up both mayo and tomato, leaving it a mushy mess. 

Every year, thousands of people travel to Bunol, Spain to take place in a massive food fight for the Tomatina Festival.

Forget Disney World — the upcoming "Eataly World" is a massive Italian food-themed park, and it looks just as amazing as it sounds.

The park is scheduled to open this November in Bologna, Italy, with over three dozen restaurants, a gigantic market, and a variety of "multimedia experiences" based on food, farming, and craft. In short, Eataly World looks like a new must-visit spot for Italian food lovers trekking through Emilia-Romagna. 

Here's everything we know about the world's first Italian food theme park.

SEE ALSO: The best breakfast sandwich in NYC is hidden in a popular tourist hotspot

When Eataly World opens on November 15, entry will be free. That's not just an opening deal — admission is always free to Eataly World.

The focus of places like Disney World and Six Flags is rides. You pay an entrance fee, and that enables you to go to Space Mountain (or whatever). 

Eataly World, however, is focused on all aspects of Italian food: growing, harvesting, processing, and craft. Much of the park's 20 acres are dedicated to farms and factories that you can visit, enabling you to see directly how Parmigiano-Reggiano is made, or how your favorite olive oil is pressed.

Here's how the park's ethos is described on the official site: "At Eataly, each forkful of pasta has a story: farmers cultivated grains, millers ground flour, pastai (pasta makers) shaped dough, distributors delivered it to Eataly, and our chefs cooked the pasta to perfection and paired it with seasonal sauce before we drop it at your table."

In many ways, Eataly World is an extension of what the various Eataly establishments around the world already do — just many, many times larger. At Eataly, you can watch pasta get made by hand and choose to either buy some to cook yourself or have it prepared by an expert cook. You can buy the guanciale, cheese, tomato and whatever else on-site, and go make bucatini all'amatriciana at home. Or you could eat it on-site.

Eataly World takes that concept to a far grander scale, where you can see the cows who produced the milk that became the cheese you're eating. Then you can see the aging process of that cheese before it became a nutty, salty, unbelievably complex and delicious sensory experience.

Or, you could simply visit for the outrageously large selection of "trattorias, starred restaurants, bistros, and street-food kiosks."

Eataly World boasts a selection of 40 different food options, ranging from more casual trattorias and street-food carts to "starred restaurants." 

Standouts thus far include Neapolitan pizza chain Rossopommodoro and cured-meat purveyor Antica Ardenga, though that's just the tip of the iceberg in terms of options. How about a shop dedicated to mortadella? Because that's totally a thing at Eataly World (it's actually called "Mortadella World," hilariously).

Millennials don't like beer as much as older generations — and it's creating problems for the industry. 

On Wednesday, UBS released its evidence lab's third annual survey of roughly 1,200 US alcohol consumers. One of the survey's areas of focus: how millennials feel about beer. 

The beer industry has been plagued by millennials' relative lack of interest. Beer penetration fell 1% from 2016 to 2017 in the US market, while both wine and spirits were unmoved, according to Nielsen ratings. 

UBS's survey of how likely millennials are to recommend different beer brands provided further evidence that this generation is simply less into almost every type of beer than Baby Boomers and Gen X.  

Compared to all consumers polled, every beer brand except Stella Artois, Dos Equis, and Miller have lower brand equity amongst millennials.

And, that's not changing as the generation gets older. Recommendation rates amongst millennials went down over the last year across the board, with the exceptions of Dos Equis, Stella Artois, and Shock Top.

In late July, Goldman Sachs downgraded both Boston Beer Company and Constellation Brand based on the data that younger consumers prefer wine and spirits to beer, as well as the fact that they're drinking less alcohol than older generations more generally.

Beer already lost 10% of market share to wine and hard liquor from 2006 to 2016. UBS believes that the trend will likely continue, writing in the research note that "big spirits brands appear better placed than big beer brands."

"This armada of boats is coming across the Atlantic to crush us and we are shooting each other with, you know, muskets and slingshots," Walt Dickinson, a cofounder of craft brewer Wicked Weed, which was acquired by AB InBev in May, recently said of squabbles between independent brewers and giants of the industry.

According to Dickinson, the "armada of boats" preparing to crush the beer industry is wine and spirits — an opinion shared by a number of other craft brewers who appeared in an AB InBev video on the topic. Beer giants need to win over millennials — or risk losing millions of dollars as younger Americans gravitate to wine and liquor.

Whole Foods now sells Amazon Echos in grocery stores. And, Amazon is now selling Whole Foods groceries. 

Soon after Amazon's $13.7 billion acquisition of Whole Foods went through on Monday, more than a thousand Whole Foods items were added to Amazon.com.

The previous Thursday, Amazon had announced that, post-acquisition, Whole Foods goods would be available on Amazon.com, AmazonFresh, Prime Pantry, and Prime Now. 

Currently, to purchase many of the Whole Foods items you need to have an AmazonFresh membership. AmazonFresh is Amazon's grocery delivery service and costs Prime members an additional $14.99 per month.

New York Magazine's Grub Street noted that the average Whole Foods stocks 35,000 to 52,000 items, so there's still a way to go before you can buy every Whole Food item on Amazon.com. 

Here's a sampling of some of the best-selling Whole Foods items available on Amazon as of Wednesday afternoon.

Cramped spaces, cinderblock walls, and low-grade lighting are the things college students typically expect from their housing experiences. You won't find any of that in the dorms on this list, however.

We've researched schools across the country to compile a list of the 11 dorms that provide the most unique living and learning experience.

From TempurPedic mattresses and private pools, to special learning communities, these dorms have all the amenities you could ever want.

Scripps College topped Princeton Review's list of the schools with the best dorms this year.

Scripps College's seven residence halls consistently rank high on best-dorms lists, and with good reason. With each dorm housing between 70 and 120 residents, they're tight-knit communities set on a beautiful southern California campus. Many of the Mediterranean-style buildings have balconies that overlook palm tree-shaded courtyards or wide grassy lawns. 

On the second floor of the Gabrielle Jungels-Winkler Hall is the "browsing room," which features intricately carved wood panels that date back to 1915. 

Washington University in St. Louis has the South Forty, a community of dorms with plenty of convenient food options.

Coming in at number two on this year's Princeton Review's list of the best college dorms is Wash U, which has a variety of luxurious accommodations inside the small-town atmosphere on the campus' South Forty area.

All 23 residence halls, both the old and the new, are outfitted with TempurPedic mattresses, and the student-run Wash-U-Wash service will pick up your dirty laundry, clean it, and deliver it to your door two days later. 

Perks of living in the South Forty include easy access to a food market, a bakery, a kosher kitchen, on-sight peer counselors, and large gathering places in LEED-certified buildings. 

One community at Arizona State University provides 1,600 residents with an Amazon Echo Dot.

The house, which was built specifically for first-year engineering students, will encourage residents to experiment with the technology, as well as enroll in classes that teach voice user interface development. 

The house is also equipped with eSpace classrooms where students can enroll in an Introduction to Engineering course, among others.

Despite claiming the title of the richest man in the world, Zara's founder, Amancio Ortega, is a man of mystery. 

On Wednesday, Ortega beat out Bill Gates to become the richest person on Earth, Forbes reported. Ortega currently has a $200 million edge over Microsoft co-founder Bill Gates, due in part to a particularly good week for the stock of Inditex, Zara's parent company. 

According to Forbes, Ortega has crowded the world's richest person three other times — but has always surrendered the No. 1 position within a day. 

Despite Ortega's enormous net worth, many people have never heard of him. He is an incredibly private man, is rarely seen in public, and has given just a handful of interviews throughout his incredibly successful career.

That career began when Ortega founded fast-fashion giant Zara with his then-wife Rosalia in 1975. Today, his retail company Inditex SA — which owns Zara, Massimo Dutti, and Pull&Bear — has 7,385 outposts around the world.

While Ortega is immensely private, we do know a fair amount about him. Here's everything you need to know about the richest man in fashion.

Its flagship location in San Francisco looks like an Apple Store meets "Westworld," complete with state-of-the-art diagnostics tools and an AI system that listens and takes notes for physicians.

The company is expanding outside its hometown with locations in other cities and a mobile doctor's office, built on an 18-foot-long trailer bed. The truck will roll through San Francisco until early September, when it leaves for other cities.

This is how Silicon Valley does the doctor's office.

In 2015, Aoun was riding his bike to Google's offices in Menlo Park — where he worked on artificial intelligence and ran the special projects division at Alphabet — when he got a call.

"Don't freak out, but I'm having a heart attack," his thirty-something relative said over the sounds of sirens blaring. "I'm in an ambulance on my way to the hospital. So what do I do?"

After months of doctor appointments, phone calls with billing offices and insurance companies, and countless hours spent on Google trying to figure out what all the jargon meant, Aoun became frustrated by how difficult the healthcare system was to navigate.

"Doctors are kind of awesome. They're incredibly smart. They're crazy well-educated. They mean well," Aoun told Business Insider. "But the problem is, they're totally set up for failure."

"It's kind of not their fault as much as, I would actually argue, it's my fault," he said. "[If I'm] representing the engineering community, we totally dropped the ball."

His relative's near-death experience was an eye-opener, Aoun told Business Insider. He set out to make the healthcare system more predictable, consistent, and convenient.

He assembled a team of some of the most brilliant minds in Silicon Valley, including one of his cofounders, Ilya Abyzov, an early Uber employee who helped launch UberX.

Founded in 2016, Forward makes over every touch point in healthcare. The company's engineers built things like diagnostics tools and a mobile app that patients use to book appointments. The technology creates a better user experience for members and their doctors, according to Aaliya Yaqub, a Forward physician and Facebook Health Center alumna.

Forward's vision has made an impression on venture capitalists. Its investors include Khosla Ventures, Peter Thiel's Founders Fund, Eric Schmidt, and Marc Benioff.

Forward's flagship location, which opened January 17, mimics the look and feel of an Apple Store. When members arrive, they sign in on an iPad at the reception desk.

"Eat fat, get fat" has been the conventional wisdom guiding American diets for the past two decades.

Yet more and more research suggests this kind of thinking is dangerously misguided.

Instead of finding evidence that low-fat eating plans offer health benefits, dozens of studies have suggested instead that these kinds of diets are unhelpful or potentially harmful. And new research points to another food category that could be the real problem: simple carbohydrates.

A large new analysis published August 29 in the journal The Lancet compared more than 135,000 people on low-fat and low-carb diets across 18 countries. The researchers found that low-fat diets were more likely to be linked with death from all causes, and found a higher likelihood of heart attacks and heart disease as well. People on low-carb diets, on the other hand, had significantly lower risk of both of these outcomes.

"Global dietary guidelines should be reconsidered in light of these findings," the researchers wrote in the paper.

Why low-fat diets don't make people thin

Several other recent studies of people on low-fat eating plans have shown similar results. An eight-year trial involving almost 50,000 women put roughly half of them on a low-fat diet, and found that the women on that plan didn't lower their risk of breast cancer, colorectal cancer, or heart disease. Plus, they didn't lose much weight, if any.

The body needs some fat to function, so people on diets that lack this ingredient won't feel full longer term.  Plus, fat helps you absorb vitamins and minerals, and is essential for blood clotting and muscle movement. It's also needed to build cell membranes (the shells that house each of your cells) and the protective shields around your nerves. 

Part of the problem with low-fat diets is the processed, "low-fat" foods that are often advertised as healthy. When food-makers remove the fat from a product, they also remove most of its flavor, so often wind up adding other "filler" ingredients like sugar to compensate.

Because foods high in simple carbohydrates like white flour and sugar lack protein and fiber, they only satiate you briefly, leaving you hangry later. This is why they're often called "empty calories."

Not all fats are created equal

Some fats are healthier than others, as a recent study published in the Journal of the American Medical Association revealed.

For that study, researchers tested what happened when thousands of people swapped out 5% of their calories from saturated fat (the type most often found in meat and dairy products) with calories from mono- and polyunsaturated fats (the kind found in olive oil, fish and nuts). They found that doing so was linked with numerous benefits, including a reduction in the risk of death and conditions like heart disease and several neurodegenerative diseases.

"Not all fats are created equal," Harvard nutrition professor Dr. Frank B. Hu, a lead author on the study, told The New York Times. "We should eat more good ones from fish and avocados, instead of animal fats," he said.

According to a health blog maintained by the Harvard Medical School, healthy fats include those from nuts, fish, and avocados; unhealthy ones are trans fats found in processed foods, and saturated fats "fall somewhere in between."

Overall, the take-home message is simple: fats from vegetables, nuts, plants, and fish are a healthy component of any diet, while an excess of simple carbohydrates is probably not.

NOW WATCH: Here's what happens to your body when you stop eating carbs

Ah, supercars! They are the thoroughbreds of the automotive world. They can cost millions, go very fast, and attract plenty of attention in traffic — and when pulling up to valet lines.

People dream about owning a Ferrari, a Lamborghini, a McLaren, a Pagani, or a Bugatti all their lives, from a tender young age right up until they experience that third or fourth midlife crisis. And though these storied brands make more domesticated, "practical" machines, it's the super-sexy supercars that capture the imagination.

But are they really all that? Well, they are. Yet they can also be total nightmares. Here's why.

1. They're lower to the ground than some reptiles

Ground clearance isn't a supercar forte. It can't be — these high-performance machines are supposed to slip though the air, cheating the wind, and their aerodynamics are designed to keep them glued to the road.

This, of course, means that a modest blemish in the roadway can result in thousands of dollars in damage to the car. America's crumbling infrastructure is an ever-present, high-stress foe.

It kind of sucks the pleasure out of driving your Lamborghini if you have to keep a constant watchful eye out for potholes and speed bumps and if you can't even really navigate your own driveway.

2. They have way too much power.

What do you do with horsepower in excess of 600 ponies? Who knows, because in 99.99% of driving circumstances, you're not going use it.

But you will still incinerate gasoline at an alarming rate. 

If you do try to tap into the power, you run a gamut of risks. You could lose control of the car and have a very costly accident. You could pay no attention to your actual speed and endure a very costly speeding ticket. 

You could also just get depressed. Nothing is sadder than a supercar stuck in traffic, looking gorgeous but with no hope of unleashing its potential. You paid for that power! But you'll rarely get to experience it.

3. It costs a fortune to buy one — and another fortune to fix one.

The cheapest supercars are still quite expensive, and you always face the question of whether your sub-$100,000 "supercar" is a true supercar. So you feel the pressure to man up for the pricier shiny metal. 

And then you will invariably:

1. Bang into something and need to get your investment repaired.

2. Have to get something fixed that goes wrong with your ride.

In either case, you'll be parting with huge sums of money — eye-watering, staggering sums, in fact, if you're used to dropping your Lexus off at the dealership for a brake job.

You may also have to wait months to get the car back.

Why do little dogs yap more often and louder than the bigger dogs? Alexandra Horowitz, the author of "Being a Dog" explains why. Following is a transcript of the video.

The reason that small dogs bark more than large dogs, I mean, I don't think it's been scientifically investigated as a lot of the questions that we have about dogs haven't.

But I would say that I think the suggestive evidence that because of their diminutive size, they need some other thing which makes them appear bigger, or formidable, or strong.

And making a lot of noise is one of the ways that animals always try to make themselves seem stronger or more formidable so that might be what little dogs are trying to do.

But I love when people get a little dog thinking that it's just like — I mean, I dont' love it, I hate when people get a little dog thinking it's just a toy, it's just easy to deal with and often they have more energy, are more rambunctious and are louder than a large dog.

We have this weird notion that little dogs are going to be toys and big dogs are hard to deal with. Large dogs are sometimes more mellower and they don't spend all day yapping and little dogs sometimes spend all day yapping and running around like mad so you know, know dogs before you take one into your house for the next 15 years.
