Soup cleanses are supposedly replacing juice cleanses among the wealthy and elite. 

"Souping is the new juicing," The New York Times declared recently.

On the surface, juice's new rival has its merits. Soup is warm, comforting, and feels like real food. 

I'm dubious of most crash diets, but soup specialists, like Nicole Chaszar of New York's Splendid Spoon, claim they're just out to help you eat better.

I set out to see what the big deal is about souping, and if it really is the new juicing.

SEE ALSO: I tried the $109-per-day diet that many Victoria's Secret models use — here's what happened

Going into this experiment, I'm willing to guess that souping is probably more pleasant than juicing.

Juicing is not pleasant for most humans, unless you are Gwyneth Paltrow or a holier-than-thou skinny rich person. Juice on its own can be good, but nobody does a juice cleanse for fun, unless that person is a masochist.

But soup reminds you of your grandma or your mother who made killer chicken soup. "[Soup is] really connected to a lot of really positive emotional memories and experiences that people have," Chaszar said to me.

She has a point: when you look back at your life, you'll never fondly recall your greatest memories sitting around the dinner table drinking juice with your loved ones unless you are this woman. You might, however, recall dining on soup with your family.

And juice cleanses are frequently criticized for their questionable nutritional value. Chaszar, who studied at the French Culinary Institute, pointed out how the process of pressing juices strips vegetables and fruits of fiber. Juice can have high sugar content, too. Soup maintains the vegetables' fiber and still packs many doses of nutrients — it's a lot easier to have a soup composed of ample vegetables and healthy oils than it is to eat ten pounds of kale. Additionally, soup cleanses often contain beans and lentils (and some even have meat) as opposed to pure raw juice, so you get more protein. 

And guess what! You don't have to punish yourself on a soup cleanse.

Here's the soup cleanse, in all its glory. A cleanse day costs $65, not too dissimilar from a day of juice cleansing.

The Splendid Spoon offers an approximately 720 calorie cleanse. I personally am not comfortable with eating that little amount of calories — and I need to function as a human being — so here's my disclosure: I planned to try all of these soups to see if they were any good. I did not solely soup. (Chaszar defended the 700 calories as something rooted in the notion of intermittent fasting, a semi-trendy form of dieting. She does not condone eating that little every day.)

Fortunately, Chaszar told Business Insider that my choice to semi-cleanse wouldn't make me a failure — a soup 'cleanse' isn't supposed to be punishing. Splendid Spoon suggests having a plant based protein and an apple midday if you're famished, and she told me I could have a regular breakfast in the morning, or soup all day and have a hearty meal at night. I decided to do some variation on that, so that I could simulate some of the experience a diehard souper might have. Was this, indeed, a cool and comforting way to suffer?

The Splendid Spoon offers a "weekly" plan — here's what comes with that.

This includes one day of pure souping and five days of ingesting a soup instead of your lunch; this plans costs $95. These swappable soups are heartier, such as lentil and kale, and Ikarian stew. (I didn't try all of these.)

"Our program is really rooted in the concept that small simple changes made every day can have a really profound impact on your health," Chaszar said to me.  

And then, on the seventh day, it's " no rules" so you margarita cleanse. I'm kidding about the last part.

Before the modern jumbo jet and its first class suites, the biggest and grandest thing in luxury air travel was the German Zeppelin Airship.

Of all the massive Zeppelin's constructed, the most famous was the Hindenburg. The Hindenburg was designed to ferry passengers across the Atlantic in serenity, with the dirigible floating smoothly through the clouds.  

The Hindenburg was the first of two "Hindenburg" Class airships constructed by the Zeppelin Company. Construction of the airship began in 1931 and was completed in 1936. The Hindenburg, along with its highly successful predecessor, the Graf Zeppelin, made numerous trans-Atlantic crossings in their brief but illustrious careers.

Constructed out of an aluminum alloy called duralumin, the Hindenburg's massive frame work was filled with seven tons of hydrogen. Hydrogen is much lighter than air, and allows the massive Zeppelin to carry more people in greater levels of luxury. However, with an ignition source, an oxidizer, and right concentration, hydrogen can also be incredibly flammable.

The Hindenburg entered passenger service in May of 1936 and carrier up 50 passengers in luxury across the Atlantic.

The legend of the Hindenburg's luxurious amenities are well know, but most have not seen them in living color. So take the opportunity to check out these wonderful photos of the Zeppelin's passengers spaces courtesy of airships.net and the German Federal Archive. 

Prior to the age of the airliner, Zeppelin airships ruled the skies over the north Atlantic — connecting cities like New York with Western Europe. Zeppelin's fleet of airships included such colossal creations like the Graf Zeppelin and the Hindenburg (seen here) along with the less famous Graf Zeppelin II.

In fact, here's a photo of Business Insider's world headquarters taken from the Graf Zeppelin in 1929.

The most well known of the Zeppelin airships was named after former German President Field Marshal Paul von Hindenburg.

The jeans we're about to present are online for sale, so we're assuming some men are buying them.

But that doesn't mean that they should.

We've consistently seen some offensive pairs out on the Street running wild with impunity, so with the help of stylist Jessica Cadmus, the Wardrobe Whisperer, Business Insider is setting down some super-easy guidelines.

"Jeans are the cornerstone of most men's casual wardrobe. They are extremely versatile, travel well, shrink to fit, and come in myriad colors and washes. They are rugged, cool, and often sexy," she said.

"However, it is still incumbent upon the wearer to select wisely because unfortunately there exist an abundance of ill options," Cadmus continued.

And we're about to show you a few of the ill-est.

Note: We didn't even get into non-pant denim. Perhaps next time.

The awkward cut.

Barneys calls these "cropped." We consider them a "taper tantrum."

It also has what our Elena Holodny calls "the old man sagging effect" on everyone's legs.

Note: This includes a ton of boot-cut jeans. Use someone with tastes' discretion.

Studded jeans.

Is Blink-182 having a reunion tour?

Huge pockets.

It's unclear how jeans with huge pockets managed to stay in some realm of acceptable fashion. They're not flattering. Wear things that are flattering.

When I planned my week-long trip to London late last year, I didn't rely on brochures or websites to make the final call on where to go or what to do — I used virtual reality.

With only a week to explore one of the greatest cities on earth, I found myself on TripAdvisor asking "Would this be worth my time?"

Then I remembered the Google Cardboard on my desk — a low-cost virtual reality viewer that you slot your smartphone into — courtesy of my mom's New York Times subscription. The Times gave a free Cardboard with each issue of its Sunday edition back in November, hoping to encourage its subscribers to use its new VR app. 

The NYT VR app is well worth checking out, but what helped calm my pre-vacation jitters was Google's own Street View app. Street View is a VR version of the Google Maps street view feature, which lets you look around from inside a 360-degree photo of an area Google has mapped out.

On a computer, phone, or tablet it's impressive, but in Google Cardboard it's incredible. I typed "Big Ben" into the search bar, selected the location, put my phone into Cardboard and I was there. 

Having a first-person 360-degree view gave me a sense of what the view would be from the corner across the street, and although it paled in comparison to actually being in that corner a week later, it was still very impressive. I used Street View to virtually "check out the sights" ahead of time. This is how I decided the London Eye didn't look too interesting, but Westminster Abbey and Buckingham Palace sure did. It also gave me a sense of the neighborhood I would be staying in, since it wasn't in the heart of the city.

After a half hour in Street View I wasn't as stressed out about missing out on any of the "must-see" locations, which freed up both my mind and time around the city. A majority of what I saw in London didn't come from my Street View experience: Little off-the-beaten-path shops, side streets, and a number of pubs, but I can't stress enough how helpful virtual reality was as a planning tool.

I'll never visit a major city again without taking a quick pre-trip spin around town.

NOW WATCH: Columbia law professor argues that 'privacy has been privatized'

In some ways marriage has taken on a terrifying role in today's society because of what can come after: divorce. It's not an unreasonable fear considering an estimated 40 to 50% of married couples in the US have divorced.

But, anthropologist and human behavior expert at Indiana University who's spent decades studying different aspect of love, Helen Fisher says that if you wait about two years before getting married, it could boost your chances of leading a happy, life-long marriage.

"There was a recent study in which they asked a lot of [dating] people who were living together ... why have they not yet married and 67% were terrified of divorce," Fisher said on Big Think.

"Terrified of not only the legal and the financial and the economic but the personal and social fall out of divorce."

Interestingly, this fear of divorce is actually giving way to healthier marriages, overall, because people are taking more time getting to know each other before tying the knot, Fisher said.

And time is the only one way to reactivate a part of the brain — responsible for logical decision making and planning — that shuts down when you first fall in love with someone new, which can explain the irrational behavior of two people who are madly in love:

"One of the problems with early stage intense feelings of romantic love is that it's part of the oldest part of the brain that become activated — brain regions linked with drive, with craving, with obsession, with motivation," Fisher, who has studied the brain on love, said. "In fact some cognitive regions up in the prefrontal cortex [shown below in red] that have evolved more recently begin to shut down — brain regions linked with decision making [and] planning ahead."

This intense feeling of love can cloud your ability to think logically or rationally about the person you're with. Therefore, by allowing time for the brain to adjust to the new situation and feelings you're experiencing, you can recognize whether who you're dating is actually right for you.

"I think ... this slow love process of getting to know somebody very carefully over a long period of time is going to help the brain readjust some of these brain regions for decision making," Fisher said. "You're going to get to know how this person handles your parents at Christmas ... how they handle your friends, how they handle their money, how they handle an argument ... etc."

Ultimately, you want to get a good sense of your partner's behavior during these real life situations, which is why Fisher suggests to wait at least two years. That way, you've been around the annual treadmill of life twice with your partner, and, therefore, should have a good sense of how they handle themselves under different circumstances.

"I think people should marry when they feel like marrying but from what I know about the brain if it were me I'd wait at least two years."

Elite boarding schools are not only highly selective, they're also well funded — some boast endowments even larger than those of prominent colleges. 

Business Insider recently published a list of the most elite boarding schools in America. The ranking was based on three metrics weighted equally: endowment, acceptance rate, and average SAT score, primarily using data from BoardingSchoolReview.com, a website that collects information on boarding schools directly from the institutions. Here, we've re-ranked the schools based solely on endowment to determine which are the country's richest.

These funds, raised from generous donors and alumni, support schools' day-to-day operations and help provide financial aid to students. At Phillips Exeter Academy — the No. 1 school on our list with an endowment of $1.15 billion — nearly half of the student body benefits from financial aid. 

Behind Exeter, Phillips Academy Andover took the No. 2 spot on the list with an endowment of $1 billion.

Read on to see the rest of the 20 richest boarding schools in America.

NOW WATCH: This man makes beautiful glass objects using dangerous, archaic methods

For the second year in a row, Phillips Exeter Academy, located in Exeter, New Hampshire, topped our list of the 50 most elite boarding schools in America.

The school touts the highest endowment of any boarding school in the country with $1.15 billion and is one of the most selective schools out there, accepting a mere 19% of applicants per year.

Exeter's eliteness is bolstered by its impressive roster of notable alumni, which includes 19 US senators, two tech founders, and a US president. 

Known for pioneering the Harkness teaching method, Exeter holds all of its classes seminar-style, with students gathered around circular tables. Through this strategy, pupils come to class prepared and ready to discuss, and engage with the material on a deeper level than could be achieved through traditional lectures, according to the school. 

Here are a handful of Exeter's most notable alumni: 

• Mark Zuckerberg, founder of Facebook. Since dropping out of Harvard to work on Facebook full-time in 2004, Zuckerberg has grown the social network into a $300 billion company. 
• Franklin Pierce, the 14th president of the United States. In 1854, Pierce signed the Kansas-Nebraska Act, which mandated that settlers themselves could decide if slavery was allowed or not within a territory's borders. The controversial bill overturned the Missouri Compromise and angered anti-slavery activists, helping to pave the way for the Civil War. 
• Gore Vidal, author and TV personality. A prolific writer, Vidal wrote 25 novels throughout his life, as well as memoirs, plays, TV shows, and a flood of essays. 
• Dan Brown, best-selling author of "The Da Vinci Code." Brown's also been recognized for his other novels, including "Angels and Demons" and "Inferno."
• Win Butler, founder and lead singer of rock band Arcade Fire. Butler's younger brother, Will, is also a member of the band, as well as a fellow Exeter alum. 
• Roxane Gay, author of "An Untamed State" and "Bad Feminist." Gay's work has also appeared in The New York Times, Slate, and The Guardian, among others. 
• Tom Steyer, billionaire hedge fund manager who founded and ran Farallon Capital Management for 26 years. Steyer sold his stake in the company in 2012 and now focuses on politics and environmental issues. 
• John Irving, author and screenwriter, known for "The World According to Garp" and "The Cider House Rules." In 2000, Irving won an Academy Award for best adapted screenplay for "The Cider House Rules." 
• Adam D'Angelo, cofounder of Quora. Friends with Zuckerberg since their days at Exeter, D'Angelo served as Facebook's Chief Technology Officer until 2010, when he quit to build Quora.

Contrary to what many advertised drug tests might promise, not all substances leave their telltale chemical signature in the body for the same amount of time. 

The moment we take a drug — whether we snort, smoke, or swallow it — our bodies begin to break it down. In the process, metabolites, or byproducts, of the drug are produced, which can linger in our blood, urine (and even in our hair) for long after the initial effects of the drug are felt. Traces of these metabolites are what drug testers look for, since they're a good indication that someone has actually used a drug rather than merely come into accidental contact with it. 

And while hair-based drug tests are fairly accurate, tests of blood and urine are simply unable to detect the vast majority of drugs, so long as you haven't used for about a week. Heroin, for example, is generally undetectable in urine after three to five days. 

As the chart below shows, traces of drugs like LSD, morphine, heroin, amphetamines, and alcohol all remain in the blood for just 12 hours or less:

For urine, the window of detectibility is a little bit wider — roughly three to six days for LSD, MDMA, and morphine, for example — and up to 30 days for marijuana:

Hair-based drug tests are the most accurate, as the chart below shows, since traces of everything from alcohol to morphine can remain in the follicle for up to 90 days:

We recently named Phillips Exeter Academy the most elite boarding school in America— for the second year in a row.

Phillips Exeter is highly selective and has educated some of the most powerful people in history. Its alumni base includes 19 state governors, five US senators, five Olympic athletes, two Nobel Prize winners, a US President, and even tech moguls like Facebook founder Mark Zuckerberg and Quora founder Adam D'Angelo.

Many millionaires and a handful of billionaires are products of the Exeter community and have helped grow the school's endowment to $1.15 billion — more than any other boarding school and larger than many colleges as well.

The fund supports many students' tuition, which otherwise costs $47,790 a year for boarding students.

When Dr. John Phillips, a graduate of Harvard and resident of Exeter, New Hampshire opened the Academy in 1781, he set out to teach young men "the great and real business of living." More than two centuries later, the now co-ed school prides itself on the strength of its network, its commitment to spreading kindness, and on its use of the Harkness Method, a unique teaching model that schools around the world strive to imitate.

In the fall of 2014, I spent the day as a student at Phillips Exeter Academy, located in Exeter, New Hampshire, to see what makes it so unique.

Phillips Exeter Academy, which we recently named the most elite boarding school in America, has a reputation as a "feeder school" — a school that sends a high number of students to Ivy League universities. As I drove to the quiet town of Exeter, New Hampshire, I expected to hate it.

Before arriving on campus, I imagined the quintessential boarding-school stereotype — Vineyard Vines-wearing, silver-spoon-fed teenagers crumbling under academic pressure, bragging about their college acceptances, and sneaking off into the woods to get high.

But I spent the day as a student in "the bubble," as students call the Exeter community, and it was nothing like I expected. I never wanted to leave.
