Back in 2009, Will Smith forked over $13.5 million and said aloha to a seven-acre Hawaiian home along Kauai's North Shore.

As reported by The Wall Street Journal, he sold it off-market for $20 million to a trust connected to Ekaterina Rybolovleva — heiress and daughter of Russian oligarch Dmitry Rybolovlev.

The trust added an additional 21 acres to the property, and all 28-plus acres are up for grabs. 

Roni Marley of Hawaii Life Real Estate Brokers holds the listing. 

With three additional building sites for either separate homes or a massive estate, the listing calls the property "a canvas waiting for the right artist's touch."

The nearby Princeville Resort means you're minutes away from award-winning golf courses and fine dining.

Built in 2006, the three bedroom, three-and-a-half bath home includes 2,715 square feet of interior living space with ocean, mountain, and coastal vista views.

"You are heartfelt, confident and opinionated. You are calm under pressure: you handle unexpected events calmly and effectively."

At least that's what IBM's supercomputer program Watson thinks of me, based on a writing sample I gave it from a story I wrote on how skinny jeans are bad for your health.

Watson, the program that famously beat humans at Jeopardy!, now has a "Personality Insights" service that analyzes your blog posts, tweets, or other text you give it access to and spits out a horoscope-like description of your personality. You can enter text in English or Spanish, and it must be at least 100 words.

The program is amusing, but the results seemed a little inconsistent.

For example, when I plugged in the text of another story I wrote on a neuroscientist who found out he's a psychopath, I got a totally different response:

"You are unconventional and somewhat inconsiderate. You are unstructured: you do not make a lot of time for organization in your daily life. You are laid-back: you appreciate a relaxed pace in life. And you are carefree: you do what you want, disregarding rules and obligations..."

Thanks, Watson!

In addition to a description of your personality, the program gives you scores on the "Big Five" personality traits: openness, conscientiousness, extroversion, agreeableness, and emotional range (sometimes called neuroticism).

It also scores you on various needs (such as love and liberty) and values (such as hedonism). You can view your personality data in a nifty graphic as well.

I also had some fun trying the program on works of Shakespeare ("You are shrewd and somewhat inconsiderate...you are comfortable using every trick in the book to get what you want"), “Harry Potter” ("You are boisterous and social... you are hard to embarrass and are self-confident most of the time"), and Taylor Swift lyrics ("You are a bit compulsive, somewhat shortsighted and can be perceived as dependent").

NOW WATCH: Here's what successful people eat for breakfast

Before ever arriving to the Island of Palawan, I knew two things: that it is part of the Philippines and that several travel magazines have coined it the “most beautiful island in the world.”

That’s a lot to live up to but as soon as I landed at the Puerto Princesa airport, I knew that Palawan would be every bit as special for me as I’d hoped.

In fact, after braving the extreme heat of Manila, the first thing I noticed was the air.

It was clearer, lighter, and as I breathed it in, I knew that despite still being in the airport parking lot, I was officially on island time. The laid-back vibe wafted through the air like it wanted to play. Looking back on it now, Palawan is like a meaning-packed book. When you re-read it, you discover little secrets you didn’t notice the first time. I’d love to return and get that chance.

Then I Went to El Nido and Everything Changed

For the better! As gorgeous as Puerto Princesa is, El Nido was the major highlight on my Intrepid Travel Philippines Island Getaway trip. Known for gorgeous sunsets (just skip to the last photo in this post for further proof) and a great snorkeling and diving destination for all experience levels, it was hard to find any fault with Palawan’s northernmost tip.

I quickly learned that El Nido can be anything you want it to be. If you’re looking for outdoor adventure, it has plenty of that and if you’re more interested in lounging on the beach without a care in the world, finding a spot in the sun is a breeze (pun intended). I did a little of both, paring a few hours of rigorous exercise with leisurely pool time and beach reading. The combination proved the perfect balance for this bohemian traveler.

“Clear blue water, high tide came and brought you in”

I wonder if Taylor Swift has visited the Island of Palawan because this line from “The Love” perfectly describes my feelings El Nido. We embarked on a full-day snorkeling and sailing trip and it was every bit as amazing as you might imagine. Starting the day around 9am, we slathered ourselves with sunscreen and prepared for a fun-filled day of sand, surf, snorkeling and thanks to our precaution, no sunburns.

The ride to the lagoons was a bumpy one but that didn’t (or should I say, couldn’t) stop me from taking photos like a mad woman. I wanted to capture every image and freeze it in time. After awhile though, I resigned and allowed myself to simply enjoy my surroundings. After all, perfection was all around me. I just needed to look.

“Life is the bubbles. Under the sea.”

Sorry, I couldn’t resist quoting Sebastian from The Little Mermaid and can you blame me? I’ve been snorkeling before but never like this. We made a couple stops throughout the day including two lagoons—cleverly named Small Lagoon and Big Lagoon. We then slowed things down with a trip to a secluded beach for a freshly prepared lunch (literally, the crew was grilling fish at the back of the boat). It was amazing to take a breather and simply look at the stunningly dramatic island scenery that almost looked too good to be true.

Hands down the best part of this day? Spotting a pod of dolphins swimming by our boat on our way back to the hotel. It’s so funny how every one of us immediately regressed to our five-year old selves upon seeing those curved fins break the surface.

The sun went down but our eyes shone bright

One of the great things about El Nido is that there’s a lively downtown area with bars, restaurants and even a few karaoke clubs. We stayed at the quiet and eco-centric El Nido Cove Resort but usually the trip opts for a budget hotel in the heart of downtown, making it easy to explore the nightlife scene without worrying about hitching a ride home. If you’re used to the US dollar, you’ll be pleasantly surprised by the beer and cocktail prices in Palawan.

If looking for a lunch spot, I highly recommend El Nido Boutique & Artcafe. The space is spread out over two levels and faces the shore. For a nightcap, I’d suggest Pukka Bar for a great outdoor setting and lively crowd. There are several bars on either side of Pukka, too.

A pool used to be a status symbol; something that told your peers and neighbors that you'd made it.

But no longer — now you need to install gigantic waterfalls and useless reflecting pools to send that same message. These types of water features are increasingly prevalent in real estate listings that crest the $10 million mark, because, in that price range, a Jacuzzi isn't even worth mentioning (since just about all mansions at that level have Jacuzzis).

With the help of  Zillow, the largest real estate network on the web, we've found some of the most enormous and extravagant water features in homes across the US.

The first thing to know here is that a "water feature" is not always a pool — even though they may look alike. This water feature in a Bradbury, California house looks like an infinity-edge pool, but the fountains jumping over it give it away. The residence is now on the market for $48 million.

At this Naples, Florida property (listed for $58 million) a reflecting pool with a decorative floor abuts the one you can actually swim in and is complemented by fountains.

To prove that his net worth is more than double the $4 billion figure touted by Forbes, republican presidential candidate Donald Trump recently submitted a 92-page personal-financial-disclosure report to the Federal Election Commission. 

The report — alleging that his net worth is in excess of $10 billion — was made public after a June document released by the real estate magnate's campaign described his net worth as being approximately $8.7 billion. 

One thing is for certain, though: regardless of how many billions Trump has, he knows how to spread his fortune around. 

Aside from running some of the best-known apartment buildings in the country, he also owns a personal portfolio of homes from Manhattan to Palm Beach, all of which are drenched in gold.

Donald Trump calls Trump Tower on Fifth Avenue "home" the majority of the time. Trump Tower is a 68-story skyscraper, and Trump sleeps in the penthouse.

Trump's penthouse has a gold- and diamond-covered door, an indoor fountain, a painted ceiling, and an ornate chandelier.

When Trump gets tired of his cosseted New York abode, he hops on his $100 million Boeing 757 and jets to one of his other mansions.

When asked if he'd rather live in a mansion or a small, windowless space, photographer Won Kim openly admits he would choose a tight, "womb-like" space over a mansion any day. Small spaces "give me a feeling of security and coziness," Kim tells Business Insider.

So when Kim stayed at a Tokyo hostel that provides its visitors with only a tight, one-person space made with untreated plywood, he felt right at home. Somewhere between a hotel and hostel, Kim describes this nontraditional space as a "guesthouse for backpackers in Tokyo" that is unlike other lodges in the city. 

Although Kim requested the hostel's exact location and name to remain anonymous, it became clear to him that the real story was the temporary set-ups within the business' walls. He began documenting residents of the hostel, noticing the diversity of the travelers, and seeing how they utilized the little space provided to make it their own, even as temporary residents.

SEE ALSO: The most bizarre places you can visit in Tokyo

According to Kim, the hostel's residents are a diverse crowd, from backpackers to recent job-hunting grads, to regular workers stationed in Tokyo.

While Kim doesn't have exact dimensions, he notes the spaces are only big enough to hold a single mattress and a large suitcase, with just enough room left over for small personal belongings.

A person of average height cannot stand upright in these confined spaces, but at about $12 USD a night, this hostel's competitive prices keep travelers coming through.

Everyone loves iced coffee when it's hot outside.

But, spending $3.50 or more on a cup of cold brew, and waiting in line for 10 minutes for a barista to make it, is a waste of time and money.

It's basic math: If you buy a $3.50 iced coffee once every weekday, that's $70 a month. Factor in the days you grab multiple cups of Joe and you're easily spending $100 or more on coffee you can just as easily make yourself. 

Priced at $24, the Hario Cold Process Immersion Coffee Brewer is a cost-efficient solution for those who are looking to cut back on money-wasting habits and keep more of their paycheck in their bank account. 

According to Williams-Sonoma, the brewer is easy to use as well: "Just add ground coffee, pour cold water on top, chill in the refrigerator for several hours or overnight, then treat yourself to a cup of smooth, aromatic chilled coffee." In the morning, simply pour your freshly made cold brew (the brewer also brews hot coffee or tea) into a to-go cup and go.

The highly esteemed National Hot Dog and Sausage Council has spoken, and their word is law: July 23 is National Hot Dog Day, so how are you celebrating?

Today, hot dogs are an essential part of American culture, from baseball franks to county fair coneys, it's safe to say that all red-blooded patriots in this country enjoy chowing down on their favorite style of dog from time to time.

In fact, the National Hot Dog and Sausage Council reports that in 2014, nearly one billion packages of hot dogs were sold in retail stores, and that number doesn't even take into account the more than 21 million hot dogs consumed at sports games, or purchases of frozen corn dogs--a personal favorite of mine.

But it wasn't always this way. Believe it or not, our founding fathers were not serving up Chicago dogs at that first fourth of July cookout. In fact, hot dogs didn't really take off in this country until the late 19th century.

Despite having been invented by hungry German butchers way back in 1487, it was the 1893 Columbia Exposition in Chicago that made them popular, as visitors from around the globe were introduced to the delicious dog, they suddenly realized just how convenient a sausage nestled in a fluffy bun could be for a meal on-the-go. 

The rest is history, and whether you're a fan of the classic New York dog or the artisan San Fran frankfurter, I think we can all agree that the best hot dog around is the one you don't have to pay for.

So in honor of this week's meaty holiday, here are all the places you can get a hot dog for free (or almost free):

7-Eleven

Last year 7-Eleven celebrated National Hot Dog Day by offering a coupon for a free 1/8 pound Big Bite dog on their mobile app. We expect a similar coupon to be available this year, so you can download the app for iOS and Android devices here.

All American Hot dog Sandwiches

This Jacksonville, FL hot dog joint will have a buy one, get one free deal on dogs from 11 a.m. to 3 p.m. on July 23.

Callahan's Hot Dogs

This Norwood, NJ eatery is offering up free dogs to customers who come in on Thursday between 11 a.m. and 9 p.m.

Dairy Queen

Last year the ice cream and hot dog joint celebrated National Hot Dog Day with a $5 chili cheese dog meal. Check their Facebook page for more info on what's happening this year!

Hop Dog

This hip new Portland, Oregon joint hasn't even opened yet, but they're having a menu preview on Thursday, where you can try all their hot new dog recipes for free--including trendy Portland-style dogs.

Kangaroo Express

Keep your eyes peeled for 25-cent dogs at Kangaroo Express, which is what the southeastern convenience store chain offered up last year in honor of this delicious holiday. Members of the military got free hot dogs, and this year we're expecting to see a similar hot dog deal announced at some point this week!

Philly Pretzel Factory

Philly Pretzel Factory restaurants are offering a free Pretzel Dog to the first 300 customers at each participating location.

QuikTrip

Last year, QuikTrip released a link to a printable coupon for a free hot dog on its website. They are yet to release it this year, so keep an eye on their Facebook page for the release of this year's coupon.

RaceTrac

Hot dog lovers can get a free dog through 7/31 when they print and present this coupon at participating RaceTrac locations.

Sonic

The drive-in chain is offering its All-American or Chili Cheese Coney Dog for just $1. The All-American comes served with ketchup, yellow mustard, chopped onions, and relish.

6951 Ohio River Road

Started by a "West Virginia hillbilly and a California city girl," Hillbilly Hot Dogs is housed in two old school buses that sit along the banks of the Ohio River, making for an unusual but fun location. Those with an especially large appetite should try the "Homewrecker," a 15 inch, one pound all beef hot dog with everything from cheese to chili to peppers.

39. The Red Hot — Tacoma, Washington

2914 6th Avenue

Diners say the beer selection at The Red Hot is unbeatable and so are the hot dogs. The beer all comes from microbreweries — most in Washington — and the hot dogs are described as "gourmet."

Ties have staged a big comeback in the past few years, and a lot of guys have gotten into learning different tie knots and matching specific knots with different types of collars.

But there is a final frontier, when it comes to neckwear.

It's all about breaking the rules and loosening up the tie without actually loosening it.

Because the big problem with a loosened tie is that it often looks just terrible. It destroys the relationship between tie and collar. It creates a bunch of distracting lines up around a man's neck where there shouldn't be any. And it makes a dude seem kind of beat and exhausted, rather than crisp and ready to take on the world.

There is, however, a way to introduce some irreverence to necktie-wearing without becoming messy.

Here's a good example, from the Instagram feed of Curtis Newkirk, who works for up-and-coming menswear brand Beckett & Robb:

I am a big supporter of combos involving grey, brown, and some blue. All @beckettrobb

A photo posted by Curtis Newkirk (@curtisanewkirk) on Jul 14, 2015 at 6:00pm PDT

Look what he's done here. He's tied his tie long, allowing it to fall well below his beltline. Received wisdom says that your tie's point should hit at or just above your belt-buckle or beltline.

He's also tied his tie so that the thinner back blade is longer than the wider front blade. 

These are both daring moves that are completely unfamiliar to the vast majority of American necktie-wearers, but that are common among Italian men. And for what it's worth, English guys routinely tie their ties long. 

The effect is to take some of the stuffing out of wearing a tie without actually wearing the tie loose or sloppy. As a plus, the slightly offbeat nature of the back blade being revealed provides a visual dynamic that makes the tie more than an obligatory sartorial noose.

Newkirk is a master of formally informal tie-wearing. Here's another example, where he breaks another rule:

Game face on today. Summer blue and green. Took a break from switching around some displays, to take a game time photo.

A photo posted by Curtis Newkirk (@curtisanewkirk) on Jul 9, 2015 at 4:33pm PDT

When worn, a tie has two sections, but most guys believe they should hide the back blade by slipping it through the tie's label or the small loop of fabric known as the "keeper."

This isn't necessary! It's far more stylish to let that back blade fly! It shows that you enjoy wearing a tie. 

But do bear in mind that this is harder to pull off with today's skinny ties. It's better if the front blade is wider than the back. An exception would be a narrow knit tie. I don't think you should ever hide the back section of one of those, given that the nature of a knit tie is inherently somewhat casual.

Give it a try! Follow Newkirk's lead and loosen up you tie-wearing mojo — without looking at all slovenly in the process.

No matter how many times a European visits the States, there are some Americanisms that Europeans simply cannot get used to.

Here are 16 things that Europeans find strange about America.

1. How are you as a greeting, not a question

When a sales clerk in the States says "how are you" it's not a question, but a way of saying "hello." No matter how often this happens to a European, they will launch into a monologue about their health and well being and ask it right back — and expect an answer.

2. Ice Cubes

Just like Americans are flummoxed by the lukewarm water presented to them in Europe, Europeans can't wrap their heads around how drinks in the US are full of ice. Plus, the average soda-to-ice ratio is approximately 30:70, leaving any cup empty after a few sips.

3. Free refills

Is this because of all the ice? Europeans will never understand why they are presented with a second cup of soda while the first one is still half full in front of them. What's even stranger though, is the fact that one can (and does) order a large soda — despite the refills.

4. Portion sizes

They're huge! Doggy bags are great — who doesn't love a two-for-one meal — but the concept virtually doesn't exist outside of the US, as generally people can easily polish off their dinner.

5. Certain food combinations

Marshmallows and sweet potatoes? Ice cream and soda? Bacon and syrup? These combinations seem odd to Europeans.

6. The Question Game

Most Europeans feel accosted when bombarded with 12,857 questions when they just want to order a simple sandwich. 

7. Tipping

The fact that the onus is on the customer to pay for someone else's employees to make a fair wage is mindboggling to Europeans. The fact that they're paying extra for someone to do their job, not even for doing it well, is astounding. Europeans also find it confusing that there's no set amount or percentage one should tip, and who gets tipped seems equally ambiguous.

8. Taxes

Yes, annual taxes are hard for everyone, but that's different. What's just nonsense is the fact that the price you see on an item is not the same one you pay at checkout.

9. Coins

What are these strange nicknames that say nothing about the coin's  value? Why is a dime smaller than a nickel, but worth more? Euro coins, on the other hand, are actually called by their numeric denomination.

10. Air Conditioning

Why is the average shop or office set to Arctic temperatures? Indoors anywhere in America during the summer is unbearably cold, and most Europeans are just not used to this. 

11. The Measurement System

It just makes no sense. How is 7/8ths an appropriate measurement? How are feet still a thing? The rest of the world has embraced the metric system, and it's high time for the US to follow suit.

12. Being cashless

Few Europeans wander about with wallets utterly devoid of cash, but America is basically a cashless society. Being able to pay for as little as a pack of gum with a card is still amazing to most Europeans.

13. The insane range of options

The average European will walk out of the average American supermarket or deli utterly bewildered by the array of choices they just witnessed. There's an entire aisle for soda? A dozen brands of milk? How many flavors of chips?

14. 24-hour stores

Convenience seems to be the cornerstone of this great country. Stores are open 24 hours a day, 7 days a week. There's a drive thru everything. Most European shops, on the other hand, close at 6pm and all day on Sundays.

15. The drinking age

In most of Europe, the legal drinking age is 18 (and in many places, it's legal for teens as young as 16 to drink alcohol) — much younger than the 21-age limit it is in the US. Europe also has a much more liberal stance on public drinking, as you are allowed to bring alcohol out on the streets — something that you generally can't do in the US, except for these American bastions of civilization.

16. Not taking vacation days

Squandering 169 million vacation days like Americans did in 2013, or not taking a single day off like almost half the country last year is completely and utterly unfathomable to a European.

Whether it's due to frugality or nostalgia, sometimes it can be tough to move on from your older tech. Just because your last-generation TV or ancient MP3 player has fallen behind the ever-advancing times, though, doesn't mean you have to replace it entirely.

Instead, you can buy other, less costly gadgets to spruce up whatever you're rolling with today.

Take Keedox's 2-in-1 Wireless Bluetooth 4.0 Audio Transmitter and Receiver Adapter, for instance, which you can buy at Amazon for $33. It allows you to take the audio from a non-Bluetooth device and wirelessly play it through a Bluetooth-enabled speaker, or a headset jacked into a connected computer or smart device.

If you want to watch TV in bed without waking your partner, you can plug the device into your TV, wirelessly pair it with your smartphone, then pop a pair of headphones into that phone. From there, you can enjoy your shows in quiet the way you would with a Roku or PlayStation 4 controller. Voila.

Keedox's solution isn't the only one out there, and it's incapable of remembering previously paired devices, but user reviews on Amazon and elsewhere have commended its above-average audio quality, powerful 300 mAh battery, and overall convenience. If you have a car, computer, or television in need of Bluetooth-audio functionality, click the link below to check out the transmitter.

Before Silicon Valley was ever known as such, there were plenty of billionaires and multi-millionaires building extravagant, hill-top homes.

One such mansion was built by the de Guignés, a family of French nobility who emigrated in the 19th century and enmeshed themselves with San Francisco's elite.

Seventy-eight-year-old heir Christian de Guigné IV is now trying to sell his family's Gilded Age estate — called de Guigné Court — which hasn't changed hands in 150 years. This will be his second attempt at offloading the property, which has been cut from $100 million to $40 million and no longer includes a condition that granted de Guigné "lifelong use" of the home.

The grandson of Christian II, who built the mansion, Christian de Guigné IV is now seemingly desperate to sell his family home.

The T-shirt's more structured, well-dressed cousin — the polo— is an article of clothing that makes men look instantly put together. They're also one of the most versatile styles of shirt; they'll complement the rest of your work wardrobe just as well as they will the shorts and boat shoes you wear when you're off the clock. 

In the summer, swapping your long-sleeve button-downs for polo shirts will prove exponentially more comfortable, too, since they have additional stretch and breathability. Avoid blaring brand logos and they'll look just as sharp as your go-to oxfords. Below, we found 11 of them for you to shop — all under $50.

The 2015 Hamptons Designer Showhouse contains 16 unique interior designs in every room of the house — including the mudroom, basement, and bathroom. Each designer was responsible for one room, which is the best calling card ever if you're a decorator looking to catch the eyes of local mansion owners on the East End. The showhouse will kick off with a gala preview party on July 25 benefiting a local hospital. The house will be open for visitors until September 7.

Most health-conscious people are familiar with the saying, "You are what you eat."

Here's the good news: That's likely not true.

As Alan Levinovitz writes in a new book, "The Gluten Lie," the real principle we should be following has little to do with what types of foods we eat. All we really need to pay attention to is how much we're eating.

His idea is backed by severalbig recent studies, one of which finds that modern guidelines on fat consumption aren't backed by scientific evidence. 

Nevertheless, the ancient idea that we are what we eat continues to inform our eating and dieting habits. Many of us still believe, at some level, that eating fat will make us fat; that eating cholesterol will give us high cholesterol.

It's one of the biggest motivators of fad diets: That cutting gluten, dodging carbs, or avoiding fatty foods will translate into weight loss. But unless you're eating less overall, that's unlikely. Here's Levinovitz:

"Low fat, low carb, low whatever:for successful dieting,the common denominator is lower consumption across the board." 

A recent look at the studies behind our current fat guidelines, for example — which state that we should restrict saturated fat to under 10% of all the calories we eat and that we shouldn't get more than 20% to 35% of our daily calories from fats — find that there wasn't evidence to support those rules in the first place.

After looking at the research on fat consumption that existed at the time, the authors of the new study write that the "dietary advice not merely needs review; it should not have been introduced."

In other words, eating some fat doesn't make us fat. Eating some cholesterol doesn't necessarily give us high cholesterol. 

So why do we still think we are what we eat?

We all know that consuming too much of anything will result in health problems. Eating too much sugar gives you cavities. Drinking too much alcohol makes you drowsy and can give you a hangover. But research shows that eating small amounts of any food — be it in the form of rich avocados, cholesterol-laden eggs, or even butter — doesn't result in problems. 

Yet we're still compelled to think that eating fat — any of it at all — will make us fat.

Levinovitz cites some psychological research, including a 2009 study by University of Pennsylvania psychologist Paul Rozin and University of Southern Maine psychologist Carol Nemeroff, to help explain why. 

For their study, the researchers wrote two descriptions of a tribal society whom they called the Chandorans. Both descriptions were the same except for one aspect: their diet. While one group of Chandorans hunted boar and turtle and ate only boar, the other group hunted boar and turtle and ate only turtle.

Then, the researchers had 167 volunteers rate the Chandoran society in terms of their speed and average lifespan.

The volunteers were consistently more likely to say they thought the turtle-eating people lived longer but were slow, while they tended to say the boar-eating people were heavyset and aggressive.

In other words, Rozin wrote in his paper, the results "are clearly consistent with the hypothesis that…subjects 'believe 'that 'you are what you eat.'"

A simple solution: be mindful of your portion sizes

Rather than focusing on cutting out any specific food group — from fat to carbs — the research suggests we might be better off simply being a little more mindful about how much of everything we eat.

Of course, there are always some foods to keep an eye out for, like those with high concentrations of a few specific ingredients. A 20-ounce bottle of soda, for example, has roughly 65 grams (just about 16 teaspoons) of sugar.

But if there's any "secret" to eating healthy, chances are it's incredibly basic. Michael Pollan said it well a few years ago: "Eat food. Not too much. Mostly plants."
