Out of 133 global cities ranked in the Economist Intelligence Unit's (EIU) recent "Worldwide Cost of Living" report — which highlights the most expensive and cheapest cities to live in — 16 US cities were represented. Eleven of those cracked the top 50 most expensive cities in the world.

The bi-annual report compares over 400 individual prices across 160 products and services, including food, drink, clothing, household supplies, utility bills, private schools, and recreational costs. All cities are compared with a base city of New York, which has a cost of living index set at 100.

One factor the EIU chooses not to use when creating the cost of living index for each city is accommodation. Roxana Slavcheva, a Cities Economist at EIU, explained to Business Insider: "We supply prices of rented accommodation for reference, but consider that to be a separate and relatively subjective item to price since choice in apartments and houses is dictated by taste, income, and family size."

Here, we've highlighted the 11 US cities that broke into the top 50 and the cost of living index for each. For reference, the average cost of living index of all the cities surveyed is 71.5 — the most expensive city in the world, Singapore, has an index of 116 and the cheapest city, Lusaka, has an index of 41.

The report also notes that the strength of the US dollar caused a few major shifts in this year's rankings and propelled more US cities into the top 50 — to give you an idea of the changes, we included each city's world ranking in 2015, as well as their world ranking this year.

Legendary car designer Henrik Fisker is making a comeback with his latest supercar, the Force 1.

The Force 1 is Fisker's latest luxury car since his then-renowned electric sedan, the Karma, which has become a distant memory since Fisker Automotive went bankrupt in 2011. 

But now Fisker has joined forces with engineer Gilbert Villarreal and Bob Lutz, the former vice chairman of product development for General Motors, to create VLF Automotive — the Detroit-based automaker behind the Force 1.

We spoke to Fisker about the Force 1 and his favorite features — here's what he had to say:

"We wanted to create the ultimate American supercar," Fisker told Tech Insider of the inspiration behind the car.

And the specs certainly support that notion — The Force 1 has a top speed of 200 miles per hour. It can also accelerate from 0 to 60 miles per hour in 3.9 seconds. 

To make it a true American supercar, Fisker said it was important the Force 1 had torque and sheer power. So he equipped the car with "the largest natural aspirated [V10] engine in the world."

"Low-end torque and power where you get really quick off the line, you always have power available, that's always been unique about specifically the American large V8 engines," he said.

That engine combined with the car's carbon fiber body means the Force 1 sure can move.

And the design is meant to reflect that power. The car has "extreme proportions" and a set-back cabin because more than half the car is taken up by the engine.

The Mar-a-Lago Club is Donald Trump's Florida resort — and home base outside Manhattan.

It's the top-ranked spa in Palm Beach on Trip Advisor, and gets five stars on Yelp. But what's it really like to stay there?

James Taylor, the famous singer-songwriter, spent a week there with his wife and children to perform at a charity gala on the property. His wife, Caroline, penned an account of their stay at the Mar-a-Lago for Vanity Fair.

Calling herself and her husband "dyed-in-the-wool, yellow dog Democrats," Caroline Taylor still attempts to offer an unbiased review of the hotel.

See what it's like to stay at the ultimate in lavish Trump real estate below:

Mar-a-Lago is a beach and pool club and spa, with rooms, suites, and cottages spread over 20 acres. The club has been the site of everything from Trump's most recent wedding to Maya Angelou's 80th birthday party, hosted by Oprah Winfrey.

It's one of the most "exotic, larger-than-life" hotels Taylor says she's ever visited. The 118-room resort was built in the 1920s by Marjorie Merriweather Post, America's richest woman, until she bequeathed it to the US government and it fell into disrepair.

Trump scooped it up in 1985 for less than $10 million, renovated it, and ultimately turned it into the society destination it is today. Taylor describes the clientele as "lacquered blondes" wearing "five-inch Louboutins."

Each day, the average American drinks about 300 milligrams (mg) of caffeine.

That's the amount of caffeine you'll find in about three cups of coffee.

But some people can drink more than that without feeling as jittery.

If you get a genetic test, like from 23andMe, you can find out if your genes give you this magical ability (or curse, depending on how you look at it).

The test shows you four particular gene variants that studieshaveshown are responsible for regulating caffeine in the body.

Here's what the results of a 23andMe test tell you about these caffeine genes.

First, some facts about caffeine. A cup of coffee has about 95 mg, while a cup of tea has 47 mg, and a bottle of soda has 44 mg.

Caffeine keeps you alert by blocking a sleep-inducing molecule in your brain. But your body eventually breaks down the caffeine with enzymes produced by the liver.

One of those enzymes is called CYP1A2, and it's encoded by the CYP1A2 gene.

I spent five years studying the daily activities of wealthy individuals.

I learned so many things that I’ve spent the better part of seven years sharing that information to help those struggling financially pull themselves out of the abyss that is poverty.

One of the many things I learned is that self-made millionaires have a very different understanding about money than everyone else. I’d like to share some of the myths about money I uncovered in my research.

SEE ALSO: I spent 5 years studying rich people, and here's the best piece of advice I can give you about money

1. Investing is just gambling

Thirty-six percent of the self-made millionaires in my study were what I like to call Home Depot Investors.

These individuals made most of their wealth by investing in stocks in individual companies. Before they purchased any stock, they would pore over the financials of each potential investment, looking for strengths and weaknesses. Then they would confer with a financial adviser to make sure their financial due diligence was correct.

They did their homework. And their homework did not end after they purchased a stock. They continued to monitor the financials of each company they invested in. If the financials got better, they invested more money. If the financials got worse, they sold their stock.

Sounds a lot like Warren Buffet, doesn’t it? To these self-made millionaires, investing is only gambling if you don't do your homework.

2. All debt is bad

Fifty-one percent of the self-made millionaires in my study were entrepreneurs. They started companies and then ran them as if their life depended on it. They took risks that would make most cower in fear. And they did not shy away from debt.

In fact, many took on enormous debt to start, grow or expand their businesses. They used debt to create a business asset that would eventually generate significant profits and make them rich.

To these millionaires, that’s good debt. Bad debt is debt that is used to finance losses in the business after the start-up period has long passed. Losses mean you’re not running your business correctly. And using debt to finance a poorly managed company is bad debt.

3. You need luck to be rich

There is a difference between random luck and opportunity luck. To the haters out there, random luck is why the rich are rich. Not so. Opportunity luck is why the rich are rich.

Opportunity luck is a unique type of luck the rich create as a result of having good daily habits. When you have good daily habits, you magnify the opportunity for luck to occur.

Good daily habits — like reading, taking care of your health, and focusing on your goals— are nothing more than automated persistent behaviors that help get you closer to achieving the goals behind your dreams, and they help attract opportunity luck.

On Wednesday we profiled Kendrick Brinson and David Walter Banks. They're a married couple and master photography team based out of Los Angeles, and shoot some of the most unique and colorful portraits in Hollywood.

But back in 2014, soon after they moved to Los Angeles, they went viral for something else entirely: their amazing make-out selfies on Instagram.

Here are some early examples:

Brinson told us that pose — her leaping into Banks's one-armed grasp for a kiss — was nothing new. It started on a trip to the Las Vegas desert about seven years ago with a group of photographer friends. Someone snapped them in that stylized embrace, and it stuck.

"I am a person who loves patterns and traditions," she said. "I think I had us do that pose again, and then once we'd done it twice I was like we have to keep doing this."

Banks added that it gave them an opportunity to have photos together, something that as photographers they rarely got.

"We constantly are traveling together and having these experiences together so were always shooting photos of each other," he said. "But there were never any photos of us together anywhere. It's basically like our family album."

They kept it up.

Brinson said, "When we're traveling we'll set up the camera on a tripod or a shoe or a car hood, and then we'll set it at 10 seconds and run and do the pose. So it's kind of this fun way of documenting our own lives and watching us change over the years."

After they went to Venezuela to teach a class, one of their students reached out to suggest they put the images on Instagram with the hashtag #brinsonbanksing. And a meme was coined.

The pose went viral, with imitators tagging #brinsonbanksing all over the world. CNN, Cosmopolitan, and even Elle France wrote about it. Buzzfeed called them "painfully cute."

"It was kind of funny because we were like, 'wait we take good photos of other people too!'" Brinson said. But the meme stuck, and now it's part of their brand.

They've kept taking #brinsonbanksing shots and putting them on their joint Instagram feed — and the grid from the top of this page also shows up on the "about" page of their website.

"I love seeing people all around the world doing it," Brinson said. "In Venezuela they'll be doing it. Someone in Argentina will be doing it. There's just this like happy pose that we did just for fun and it's bringing joy to other people I love it."

It's a great example of people seizing on the weird curveballs the internet sends their way.

Here are some of our favorite #brinsonbanksing shots on Instagram.

It may no longer be 2015, but battery-powered self-lacing sneakers are finally going to be a reality.

Nike announced the release of the Nike HyperAdapt 1.0 on Wednesday, the company's first, powered self-lacing sneakers that will be available for purchase.

The long-awaited kicks will be available around the holidays this year.

No word yet on price, but in the immortal words of Marty McFly, "Power laces, alright!"

Meet the Nike HyperAdapt 1.0

A sensor in the heel of the shoe automatically tightens the laces when you step in, and two buttons on the side of the shoe tighten and loosen the lases. "You can adjust it until it's perfect," Tiffany Beers, a senior innovator at Nike who was the technical lead on the project, said in a statement.

The idea of powered, self-lacing sneakers has been batted around since at least 1989, when Marty McFly, Michael J. Fox's character in "Back to the Future: Part II" wore a pair.

There been rumors that Nike had for years been working on shoes that used such technology, but this is the first pair that will be widely commercially available. (The company made a special pair for Fox and delivered them to him on October 21, 2015, which is officially "Back to the Future Day.")

The shoes have been years in the making.

According to Nike, the company worked for years on getting the technology right, and it even experimented with a snowboard boot that had an "external generator."

In 1996, Google was still a research project at Stanford, the state-of-the-art PC operating system was Windows 95, and Amazon was a small startup selling books.

And Steve Jobs was not yet back at Apple when he gave a remarkably prescient interview to Wired's website the same year. Although the iMac, iPod, and iPhone were still years away, and Jobs was working at NeXT, he clearly saw where the computing industry was headed.

And although his later work at Apple clearly influenced the way things turned out, he still offered a slew of predictions that are shockingly accurate today.

Here's what Jobs got right:

Jobs' major prediction was that the web will be ubiquitous. Sure, lots of people predicted that, but he made a remark about "Web dial tone everywhere" that does hint at the mobile-first world of today.

"There will be Web dial tone everywhere. And anything that's ubiquitous gets interesting."

Another big prediction: Commerce was going to be killer on the web.

When asked about the main beneficiaries of the web, Jobs said that it would be people who have something to sell: "It's commerce. People are going to stop going to a lot of stores. And they're going to buy stuff over the Web!"

Amazon founder Jeff Bezos was paying attention, even though Amazon was only a small book-focused startup at the time. Twenty years later, Amazon did $105 billion in net sales in 2015 while retail chains like Walmart are struggling to keep up and shuttering stores.

The future of virtual reality is upon us. Meet the HTC Vive.

Phone manufacturer HTC and gaming company Valve, responsible for the immensely popular Steam digital distribution platform, teamed up to create a virtual reality headset that offers 360-degree room-scale motion tracking. All that jargon means users can explore and interact with the universe around them, without bumping into real walls and furniture.

The HTC Vive should give Facebook-owned Oculus a run for its money.

While the final hardware doesn't start shipping until April, I recently got my hands on the Vive Pre development kit. I'll be posting a review once I've had more playtime, but in the meantime, check out what comes in the box.

When I saw the enormous box the HTC Vive came in, I thought, "this is a little ridiculous for just a headset."

Alas, the HTC Vive is so much more.

The headset itself was one of the first things I unpacked. As some early reviews warned, it's rather bulky.

Donald Trump’s butler has seen it all.

From the times that Ivanka Trump, the owner’s daughter, ordered the gardeners off the grounds so that she could swim in the pool naked, to the day the historic library was turned into a bar.

From the happy day Mr Trump married Melania Knauss at the Florida estate, with Hillary Clinton watching on, to the sad moment when he was ordered to move out of his apartment in the 118-room Mar-a-Lago property by Marla Maples, Mr Trump’s then wife.

Anthony Senecal, 74, has worked at the estate for almost 60 years — almost half of the time for Mr Trump.

“You can always tell when the king is here,” said Mr Senecal, pointing out the rows of secret service cars parked outside.

The house was built by Marjorie Merriweather Post, a cereal heiress, in the 1920s. When she died in 1973, she left the house to the United States government with the idea that it would become a presidential retreat.

But the upkeep proved too expensive, and ownership was transferred back to Mrs Post’s daughters, who sold it to Mr Trump for less than $10 million (£7.07m) in 1985. He turned it into a private club a decade later.

Mr Senecal has told The New York Times about his long-time boss who, on being told in 2009 that Mr Senecal wanted to retire, told him: “Tony, to retire is to expire. I’ll see you next season.”

What the butler saw:

He does his own hair

Mr Trump’s hair has, for decades, been a source of fascination to the American public.

And Mr Senecal revealed that, despite the estate having a salon, the billionaire preferred to style his own hair.

He only needs four hours of sleep a night

Like Margaret Thatcher, General David Petraeus, Yahoo CEO Marissa Mayer and Pepsi's Indra Nooyi, Mr Trump sleeps only for four hours a night, his butler said.

Then he rises before dawn to read the newspapers before playing golf.

The White House has had a light-sleeping incumbent before. George W Bush was famously in bed by 10pm, but Bill Clinton frequently survived on four or five hours sleep.

He likes his steak rock hard

Mr Trump famously owned a steak company, which went out of business. He still sells “Trump steaks” at his venues — but they are now sourced from a variety of other producers, rather than Mr Trump’s own supplier.

But the New Yorker’s decision to go into the steak business may have been a surprise to those who know him, given that his butler confirmed The Telegraph’s observation that he likes his steaks well done.

“It would rock on the plate, it was so well done,” said Mr Senecal.

Confidence is one of the greatest gifts a parent can give their child. 

Carl Pickhardt, a psychologist and author of 15 parenting books, says a kid who lacks confidence will be reluctant to try new or challenging things because they're scared of failing or disappointing others.

This can end up holding them back later in life and prevent them from having a successful career.

He says "the enemies of confidence are discouragement and fear," so, as a parent, it's your job to encourage and support your child as they attempt to tackle difficult tasks.

Here are 12 more tips for raising a confident child:

DON'T MISS: The 27 jobs that are most damaging to your health

1. Appreciate effort no matter if they win or lose.

When you're growing up, the journey is more important than the destination. 

So whether your child makes the winning goal for his team or accidentally kicks it out of bounds, applaud their effort, Pickhardt says. They should never feel embarrassed for trying.

"Over the long haul, consistently trying hard builds more confidence than intermittently doing well," he explains. 

2. Encourage practice to build competence.

Encourage your child to practice whatever it is they're interested in — but do so without putting too much pressure on them.

Harmony Shu, a piano prodigy, told Ellen DeGeneres that she started practicing when she was just 3 years old.

"Practice invests effort in the confident expectation that improvement will follow," Pickhardt explains. 

3. Let them figure out problems by themselves.

Landing after a long flight should feel like a moment of triumph—you're about to begin a new adventure, or are finally home after a great trip.

But most of us are more apt to feel … dirty and exhausted.

Sitting in a dry, cramped plane cabin for hours isn't exactly luxurious, but there's a method to end every flight looking and feeling like your best self. Here's how.

Employ Hidden Comforts

For some people, comfort isn't just wearing cozy clothes—it's also about feeling like you look good. Comfort and fashion aren't mutually exclusive, which is why it's a good idea to take advantage of subtle comforts.

Throwing some gel insoles in your favorite pair of chic boots and wearing packable slippers on the plane are easy alternatives to those running sneakers that scream "tourist."

Try short boots that are easy to walk in, like this sleek Ralph Lauren pair you can wear virtually everywhere, and add some massaging gel insoles. The same trick works just as well for men's shoes.

Eat and Drink Wisely

You're bound to feel jetlagged and bloated upon arrival if you indulge in unhealthy food and drink on your flight. Drink water or tea instead of soda, juice, or alcoholic beverages—alcohol will upset your sleep cycle.

When you're making food choices, remember that salt and sugar will dehydrate you, making jetlag worse and weakening your immune system. Nuts are typically a better option than the chips, cookies, or pretzels typically available. Or, avoid inflight offerings altogether and bring your own healthy snacks.

RELATED:How to Stay Healthy While Traveling

Brush Up

Don't forget to brush—your teeth and your hair. Bad breath and bed head are easily avoidable if you plan ahead. Plane lavatories are covered with germs, so use a pre-pasted, disposable toothbrush that you can just toss after using. And there's no underestimating the reviving power of floss and mouthwash.

As the final touch, run a comb through your hair (unless you've got curly hair, then, don't). If you're not ecstatic about buying all those travel-sized toiletries, try ordering a Carry- On Caddy, customizable plane packs that are delivered right to your door.

Nuclear submarines

The Navy uses three kinds of stealthy nuclear submarines to carry out missions around the world.

Attack submarines hunt enemy vessels but can also launch cruise missiles at land targets, guided missile subs carry up to 154 cruise missiles to strike land targets, and fleet ballistic missile submarines carry nuclear missiles that can wipe out entire cities.

B-2 bomber

The B-2 stealth bomber is capable of piercing enemy air defense networks because of its stealthy design.

Even if enemies do spot it, missiles have trouble engaging the aircraft due to its reduced infrared, acoustic, electromagnetic, visual, and radar signatures.

Aircraft carriers

Always a favorite, aircraft carriers are floating bases that launch strike aircraft and provide a command center for naval forces. As the Navy likes to brag, they are “So big they carry their own zip code.”

The Navy currently has 10 Nimitz-class carriers in active service and is bringing the first of the larger, more capable Ford-class carriers online this year.

Professional social situations can be awkward. And, unfortunately, many people wind up making fools of themselves because they don’t understand that etiquette rules in business differ from those in other settings.

In "The Essentials of Business Etiquette," Barbara Pachter writes about the rules people need to understand to conduct and present themselves appropriately in professional social settings.  

We looked through the book and spoke to Pachter to find the most important tips on how to introduce yourself, how to dress, and what to order at restaurants.

As it turns out, a lot of these rules should be followed in everyday life as well as business.

Vivian Giang contributed to an earlier version of this article.

Stand when you're being introduced to someone.

"Standing helps establish your presence. You make it easy for others to ignore you if you don't stand. If you are caught off guard and cannot rise, you should lean forward to indicate that you would stand, if you could," Pachter writes.

Always say your full name.

In a business situation, you should use your full name, but you should also pay attention to how others want to be introduced.

If your name is too long or difficult to pronounce, Pachter says you should consider changing or shortening it. Or you should consider writing down the pronunciation of your name on a business card and giving it to others.

Always initiate the handshake if you're the higher-ranking person or host.

In today's workplace, the host or the higher-ranking person, regardless of gender, should extend their hand first, she writes. "If the higher-ranking person fails to do so immediately — often because of gender confusion — the lower-ranking person should extend his or her hand without missing more than a beat."

Either way, the handshake must happen. "In the United States, the handshake is the business greeting. If you want to be taken seriously, you must shake hands and shake hands correctly."

From country to country, monetary units vary nearly as much as the cultures and languages that use them. But have you ever wondered why a dollar is called a "dollar"?

Dollar

The dollar is the world's most common currency, used in the US, Australia, Canada, Fiji, New Zealand, and Singapore and elsewhere.

According to OxfordWords, the Flemish or Low German word "joachimsthal" referred to Joachim's Valley, where silver was once mined. Coins minted from this mine became "joachimsthaler," which was later shortened to "thaler" and which eventually morphed into "dollar."

Peso

"Peso" literally means "weight" in Spanish.

In the early 1960s, British programmer Stephanie Shirley went under the pseudonym "Steve" on business letters, just so she could get her foot in the door.

Jobs in tech were largely held by men, which, sadly, is still true today. On average, tech companies hire 14% female engineers, while only 27% of those working in computer science and math are women. 

Shirley (who now works as a full-time philanthropist) hopes more women will pursue careers in STEM. She went on to start her own software company, the F.I. Group, in 1962, employed mostly women, and gave them significant shares in the business. At her peak, she was worth over $221 million.

13 years later, equal opportunity legislation was passed in the UK, and she had to start hiring men.

"We started to employ the men after 1975 — if they were good enough," she said in an interview with PBS.

The broadcast company tells her story as part of its new animated interview series, called "Blank on Blank." Check it out below.

Born in Berlin, Shirley was lucky enough to escape the Holocaust for London at age 5. The experience put her life in perspective.

She found her passion in programming, and started the F.I. Group in 1962. That same year, The Guardian mentioned her work in an article that read, "Extraordinary woman, Steve Shirley, writing computer programs in between feeding her baby and washing the nappies."

The article inspired other women, she says, since she was able to take care of her child while also building a career. "We pioneered home working, job sharing, flexible working," Shirley says.

A new video secretly filmed by two women inside Raqqa, Syria shows an inside view of what ISIS has made its de facto capital.

Militants captured the northern Syrian city in 2014. Since then, foreign militants have flocked to the city and other strongholds under their control, instituting strict control over those who live there.

Minor infractions can carry major punishments, and women have few rights under ISIS' strict enforcement of Shariah law.

"I can't wait to dress the way we used to in the past," says one of two women who filmed there, at the risk of being killed by militants if discovered. The video was shot in late winter for Expressen TV, a Swedish affiliate of CNN.

Here is the terrifying world they are forced to live in.

The women are forced to wear veils in public, under threat of public flogging or worse. They are covered and have their voices changed for interviews, since they remain in Raqqa.

Their hidden spy cameras show what life is like on Raqqa's streets.

Each year on March 17, the Irish and Irish-at-heart come out in droves to pubs and parade routes to celebrate the patron saint of Ireland. But there's enough rich Irish culture to last the whole year round.

We scoured Celtic folklore, online forums, the Bible, and even our favorite Irish pub in New York City to find some beautiful and just plain weird sayings used on the Emerald Isle. Some of the sayings are historic, out-of-use proverbs with original Irish Gaelic translations (today, as little as 30% of the population in the Republic of Ireland speak Irish). Others are examples of modern slang said in English, the shared official language.

Here are 15 Irish expressions to break out on St. Paddy's Day.

May the road rise up to meet you.

You may recognize this popular blessing (in Irish Gaelic: Go n-éirí an bóthar leat) from Catholic weddings or cross-stitched pillows in Nan's house. One of the main characteristics of Celtic Christianity is the use of images of nature to show how God interacts with people.

"May the road rise up to meet you/ May the wind be always at your back/ May the sun shine warm upon you face ..." uses everyday images to mean, may God remove obstacles in your journey through life.

What's the craic?

Greetings like "Any craic?" and "How's the craic?" give rise to potential awkward misunderstandings for tourists, because craic is pronounced like "crack." The most straightforward definition is fun or enjoyment, and it can substitute for "How are you?" A typical response is "divil a bit," which means "not much."

Sláinte!

In an Irish pub, patrons toast each other sláinte (pronounced "slaan-sha") as they clink glasses of Guinness. Derived from the Old Irish adjective slán (which means "safe"), sláinte literally translates as "health" and is used as a stand-in for the more time-consuming "I drink to your health!"

Tweets are now being shown out of order in a new algorithmically-powered feed instead of reverse chronological order. While an algorithmic timeline was first announced in early February, it was an opt-in setting until Twitter started turning it on for everyone this week.

Luckily, you can still opt out of seeing tweets out of order in account's settings. Here's how to do it.

Twitter has always displayed tweets in reverse chronological order, so it can be kind of jarring to see the random time stamps.
