Writing an email isn't so hard, but figuring out how to sign off can be a real challenge.

Is "cheers" too casual? Too pretentious? Too British? Is "sincerely" timeless and professional, or stodgy and overly formal?

Perhaps, as Matthew J.X. Malady persuasively argued at Slate, we should just call the whole thing off and ditch the email closer altogether.

But as anyone who has sat staring blankly at a screen weighing "best" vs. "all best" vs. "all the best" knows, not signing off doesn't feel quite right either — especially if the context is professional.

"Not closing seems way too abrupt,"Barbara Pachter, a business etiquette expert, tells Business Insider. "If you have a salutation, you should have a closing to balance it out."

Will Schwalbe, who coauthored "Send: Why People Email So Badly and How to Do It Better" with David Shipley, agrees, pointing out that "we don't go around in life barking orders at one another, and we shouldn't on email either."

And, manners aside, the email close serves a practical function. It helps "define the personality of the email's content," says Aliza Licht, author of the career guide "Leave Your Mark."

It's also an opportunity to define or redefine your relationship to your correspondent, Schwalbe adds. A shift from "love" to "best," for example, indicates that you may have a problem.

If we accept — at least for the moment — that email sign-offs are here to stay, the question becomes which one to use, and in what contexts to use it.

We had Pachter, Schwalbe, and Licht weigh in on 29 common email closings. Here are the ones they say to avoid in most situations — and which one to use when you're just not sure.

This is an update of a story originally written by Rachel Sugar.

THE WINNER: 'Best'

All three experts agree that "best" is among the safest possible choices — inoffensive and almost universally appropriate.

So when in doubt, go with "best."

Sign-offs to avoid in most situations:

'Thanks'

"Fine if it's for a favor the person has done, but obnoxious if it's a command disguised as premature gratitude," Schwalbe says.

Licht agrees. It "comes off as not really that thankful," she says. While it doesn't particularly bother Pachter, the consensus is that you can probably do better. Skip.

For most people visiting a famous landmark, there is a quintessential angle to capture to get that perfect, iconic Instagram.

Photographer Oliver Curtis, however, has turned his back on that idea, and has spent the last four years taking pictures of what lies behind famous sites. From the Statue of Liberty to Christ the Redeemer, Curtis captures lesser-known views.

His work will be on display at the Royal Geographic Society in London from September 19 to October 14. The exhibition is called "Volte-face," after a Latin phrase meaning to turning around to face the opposite direction in movement or attitude.

We talked with Curtis about his work, and his travels.

The Statue of Liberty — New York City

Curtis said his inspiration for the project began in 2012 at the Pyramids of Giza. "Like many of the great monuments of the world, when you first encounter them you feel that you have somehow seen them before," he told INSIDER in an email. 

The Mona Lisa — Paris, France

"It is very easy to whisk through and see all the angles and features one expects and is expected to see," Curtis explains. Here, he shows a lone tourist observing "The Wedding at Cana," a painting by Paolo Veronese that hangs directly across from famous "Mona Lisa."  

The Colosseum — Rome, Italy

Many historic landmarks are swaddled in souvenir carts. Curtis turned around at the Colosseum in Rome to capture a close-up of plastic-wrapped "David" replicas.

From blueberries to blackberries, by the time summer rolls around, it's hard to resist adding sweet, sometimes tart berries to virtually everything. 

But, is there a berry that is healthier than the rest? We decided to investigate.

The botanical term "berry" is pretty broad. Technically, a berry is any fleshy fruit that has a singular ovary, so everything from a watermelon to an eggplant qualifies.

So for this ranking, we've stuck to edible berries that fit the botanical description, without getting too broad, while also throwing in some berries that are technically misnomers.

To rank them, we stacked up their nutritional content. Areas like total carbohydrates and calories worked against their ranking, while vitamins A, B6, C, potassium, iron, and fiber counted toward a better ranking. All the berries were counted in one cup increments in their raw form.

No. 17. Huckleberries

Huckleberries, the state fruit of Idaho, don't have a lot of nutritional content going for them. They have very few vitamins and nutrients. Huckleberries are typically only found in the wild, but if you can find them, they taste good on their own or in pastries. 

Calories per cup: 126

No. 16. Grapes

Grapes, surprisingly, are berries but they don't offer much in the way of nutrition compared to others. They are mostly just water and sugar. 

Calories per cup: 62

No. 15. Blueberries

Blueberries, like grapes, are mostly just water and sugar, though blueberries do contain a quarter of your daily vitamin C intake.

In 2015, Business Insider published a list of ways to make yourself more attractive.

We learned that walking a dog and playing good music are easy ways to give yourself a boost.

But lately we've been wondering: Aren't there things we're all guilty of doing that can decrease our attractiveness?

The answer is almost definitely yes. What follows is a list of common traits and behaviors that can make it harder to impress the object of your affection.

Read on and find out how you might be sabotaging your own sex appeal.

Sleep deprivation

We generally look a lot less attractive after skimping on sleep.

In 2010, researchers took photos of people who'd slept for at least eight hours the night before and people who hadn't slept in 31 hours. Other participants rated the people in the photos on different criteria.

Not only were the sleep-deprived people perceived as more tired (obviously), but they were also perceived as less attractive, less healthy, and sadder.

Being mean

Do nice guys really finish last?

For a 2014 Chinese study, researchers had men and women look at photos of other people, all displaying neutral expressions.

Some of those photos were accompanied by the Chinese words for "decent" and honest"; the others were accompanied by the Chinese words for "evil" and "mean"; still others weren't accompanied by any information.

Participants ended up rating people least attractive when they were described as evil and mean.

Contractive body language

If you've heard about the "power pose," you know that expanding your body can make you feel more powerful and confident, while curling inward can make you feel less so.

According to 2016 research, that contractive body language can also make you seem less attractive. In one study, researchers created profiles for men and women on a GPS-based dating app. In one set of profiles, the men and women were pictured in contractive positions — for example, by crossing their arms or hunching their shoulders.

In the other set of profiles, the same men and women were pictured in expansive positions, like holding their arms upward in a "V" or reaching out to grab something.

Results showed that people in expansive postures were selected more often than those in contractive postures. And men pictured in contractive postures seemed to be at a special disadvantage.

The Powerball lottery, which will be drawn Friday evening, has an estimated jackpot of $508 million, the seventh-largest in US history.

It's a lot of money, but if you do the math, buying a ticket probably won't be worth it.

Even if it does pan out, winning the lottery will not solve all of life's problems.

In fact, many people's lives became notably worse after they got super rich, and they managed to lose it all quite quickly.

Mandi Woodruff and Michael B. Kelley contributed to earlier versions of this report.

Lara and Roger Griffiths bought their dream home ... and then life fell apart.

Before they won a $2.76 million lottery jackpot in 2005, Lara and Roger Griffiths hardly ever argued.

Then they won and bought a million-dollar house and a Porsche.

But six years after their win, Roger drove away in the Porsche after Lara confronted him over emails suggesting that he was interested in another woman.

Their 14-year marriage was over, a freak fire gutted their house, and every penny of their fortune was gone.

Bud Post lost $16.2 million within a nightmarish year — his own brother put out a hit on him.

William "Bud" Post won $16.2 million in the Pennsylvania lottery in 1988 but was $1 million in debt within a year.

"I wish it never happened," Post said. "It was totally a nightmare."

A former girlfriend successfully sued him for a share of his winnings and his brother was arrested for hiring a hit man to kill him in the hopes that he'd inherit a share of the winnings.

After sinking money into various family businesses, Post sank into debt and spent time in jail for firing a gun over the head of a bill collector.

Bud now lives quietly on $450 a month and food stamps.

Martyn and Kay Tott won a $5 million jackpot, but lost the ticket.

Martyn Tott, 33, and his 24-year-old wife from the UK missed out on a $5 million lottery fortune after losing their ticket.

They were able to convince officials, but since there is a 30-day time limit on reporting lost tickets, the jackpot became the largest unclaimed amount since the lottery began in 1994.

"Thinking you're going to have all that money is really liberating. Having it taken away has the opposite effect," Kay Tott told The Daily Mail. "It drains the life from you and puts a terrible strain on your marriage. It was the cruelest torture imaginable."

Apple just gave everyone the opportunity to try out its public beta of iOS 10, and one of the coolest features we found was its uncanny ability to keep track of your car whenever you leave it.

Built into its updated Maps app, the genius feature will save you from losing your car in a massive parking lot, or from having to snap a photo or jot down GPS coordinates in order to find it again.

Because, after we tested it, we realized that it just automatically works.

And it's amazing.

Dude, where's my car? Everyone's had that sinking feeling of forgetting where they parked.

But fortunately, Apple Maps in iOS 10 will remember when you forget.

It's pretty simple in how it works. Whenever you are not at home and you stop somewhere, Maps will automatically note that you parked your car and started walking away.

You don’t just have to drink green tea for it to be helpful (although it does have many health benefits).

Here are many useful ways to use it, other than just for your drinking pleasure.

Dark circles and puffy eye relief

After having one (or ten) too many drinks at the bar last night, or pulling an all nighter to study for your chemistry test, many of us can understand the puffy eye struggle. It’s always embarrassing to walk into class and have everyone look at you and think, “haha, that girl is hungover.”

Instead of making that walk of shame, brew a cup of green tea. Place the cool tea bags over your closed eyes and let them sit there. The tannins in green tea constrict the capillaries and blood vessels under your eyes that tighten the skin. The caffeine in the tea also shrinks the blood vessels under the skin that help with swelling and puffiness.

Acne treatment

Whether we like it or not, at some point in time almost all of us havestruggled with breakouts or acne. Next time we’re freaking out over a small breakout, try looking for a cleanser with green tea extract.

The antioxidants found in green tea such as polyphenols and epigallocatechin-3-gallate help regulate inflammation, which helps to reduce acne. Green tea also helps regulate insulin levels by reducing carbohydrate absorption and increasing insulin secretion. The regulation of insulin levels helps with fighting acne. Green tea causes an increase of molecules that bind sex hormones, which reduces levels of bioactive hormones (the hormones that cause our skin to go crazy and wreak havoc)

Bleeding Reduction

Hate holding napkins on cuts or having to use band aids? Boil some water and steep a tea bag. Once the bag and water have cooled, place the tea bag, or a rag soaked in cooled water, onto the cut and let it sit. The tannins and caffeine in green tea shrink blood vessels, which ultimately help to stop the bleeding.

There's no doubt about it — Serena Williams is a badass athlete.

Since she started playing tennis at age three, the 34-year-old tennis star has become one of the most dominant athletes around.

She's also a businesswoman, a philanthropist, and a karaoke fan. In between tennis matches and practice, she still found time to pop up in Beyoncé's "Lemonade" video.

As Serena prepares for the 2016 Wimbledon finals July 9, here are 20 reasons why she is a badass and the ultimate athlete:

Serena Williams has been playing tennis since she was three and has since become one of the most dominant athletes of all time.

Outdoorsy types have their own unique organizing struggles. You see, bikes and surfboards and other sporting equipment are big. And they're really hard to store neatly at home–especially without a garage or a mudroom or even more than a few hundred square feet to work with.

These house tours, though, managed to make it work, finding tight and tidy spaces where they could store some big equipment at home.

In Carlos & Laura's Stunning Spanish Home, they store their bikes right in the entryway on wall-mounted hooks. The color and pattern in the room help distract from the bikes.

In Audrey's Cozy Industrial Soho Apartment, she keeps a surfboard right in the entryway, too. Because it actually coordinates with the room, the surfboard here is storage and a cool decor accessory.

The same goes for the bicycle in Audrey's living room. It's propped up on a pedestal, so to speak, and becomes art for the room.

Chris Pratt and Anna Faris celebrated their 7-year anniversary this week.

In Hollywood years, it's a lifetime, but the couple still act like newlyweds.

Not only do they ham it up for the red carpet, but they post sweet, revealing photos to Instagram giving fans a glimpse into their fun family life at home.

"Our relationship has made me believe in divine intervention and destiny," Pratt said in a Reddit AMA last year. "She and I grew up 20 minutes away from each other but never met until we met in LA. We both got our start in horror spoofs... We both have parents that have suffered with MS. The similarities go on and on."

Chris Pratt, 37, and Anna Faris, 39, are adorable.

The couple met in 2007 while filming "Take Me Home Tonight," in which they played love interests, but they're originally from neighboring towns in Washington.

By late 2008, the couple were engaged.

Arenal Volcano stands 5,437 feet above sea level, overshadowing the town of La Fortuna, which is about two hours from Costa Rica's capital, San Jose. The town is called “The Fortune” because it was spared from the volcano’s deadly 1968 eruption. It's an appropriate name when I think about my fortunate experience there last summer.

This time last year, I was stranded in the jungle -- 40 minutes outside of La Fortuna -- after my driver, a local farmer who operated a shuttle service, ditched me. It was one of the many obstacles I faced while living alone in Costa Rica, but more on that later.

Bottom line: No one can tell you what to expect when traveling solo to another country. As I’d learn, living in Costa Rica by myself would be a journey filled with challenges. Still, I'd return home to New York having had one of the best experiences of my life. For those contemplating a trip to Costa Rica alone, here are some dos and don'ts that I learned the hard way.

1. Bring rain gear.

Some say I made a mistake when I planned my vacation during Costa Rica’s rainy season, which runs from May to November. Others argue that the low season, which lacks crowds, is a prime time to visit. Every afternoon brought thunderstorms that shook my little cottage in La Garita, which was located about 30 minutes from San Jose International Airport. My neighbors like to scare all the newcomers with a story about the time the gardener was struck by lightning, so naturally I developed a new fear. But there was a bright side to all the rain: the gorgeous green scenery. 

Tip: Bring a pair of waterproof shoes, a poncho, and an umbrella, if you plan on being in Costa Rica during the rainy season. Invest in a waterproof cell phone case, too. My iPhone died one day after a spontaneous rainstorm interrupted my jog.

2. Pack back-up chargers.

Speaking of lightning storms, voltage fluctuations and power outages are common in Costa Rica. In my experience, these caused the rubber encasing around my MacBook and iPhone power cords to turn into putty. And when I returned to the U.S., I had to replace all of them.

Tip: During a thunderstorm, unplug your devices. Costa Rican plugs are the same as in the U.S. and Canada, but outlets don’t accommodate three-prong plugs, so bring an adapter. You may also want to bring extra chargers, if you plan on being in the country for an extended period of time.

3. Be wary of the food and water.

Two weeks into my trip, I became violently ill. The culprit was either eggs I bought at a countryside market or boiled tap water. In Costa Rica, eggs aren’t refrigerated because they believe the natural coating protects against bacteria contamination. In the U.S., eggs must be refrigerated because that natural coating is washed off. There are different opinions about which method is better. As for the water, the Costa Rican Water and Sewage Institute (AyA) monitors its H2O regularly, but the quality varies by area. I met many expats who drank straight from the tap and didn't exhibit any negative reactions. 

Tip: The key is to be cautious. Drink bottled water. You might even want to ask your doctor to prescribe antibiotics before you travel as an added precaution.

My freshman year in college, I got a weird notification on my days-old LinkedIn profile.

Let me provide you with some context. My account was barely set up — I'm not even sure if I even had a profile picture at that point.

I'd only slapped the account together after getting hyped up about making connections and garnering professional opportunities at the college's career center (so fun).

The problem was, I didn't really know how to wield my new social media platform. For the few days I had it, I'd mostly just used it to check out my high school crush's profile. 

And then I got this alert saying that one of my new dorm mates had viewed my account.  

I remember sitting at my desk and feeling a cold dread seep over me. I hadn't realized that you got notifications when other people view your page (yeah, I know, there are certain privacy settings that eliminate this, but I was totally clueless back then).

Once I realized that this guy probably knew I was stalking him, my reaction was swift and uncompromising. I deleted my LinkedIn, got on a plane, and fled to a town on the edge of the Arctic Circle, where I've been living ever since. 

Well, I did that first thing, at least. I deleted my fledgling LinkedIn account. I didn't get another one until about a year later.

So that's my biggest LinkedIn-related failure. Obviously, I was young and foolish and treated the account more like a nerdier version of Facebook than a means of making professional connections. Because of my melodramatic decision, I may have missed out on some interesting opportunities. Today, I'm a LinkedIn all-star and I'm very happy with my account (except for the fact that the profile strength bubble never quite fills all the way up— that drives me insane). 

I talked to career expert Nicole Williams to get her take on common mistakes people make on LinkedIn. She told me about four widespread faux pas:

DON'T MISS: I let an expert tear my horrible cover letter to shreds — here are the mistakes I won't make again

DON'T FORGET: I interviewed at one of the world's biggest banks and I completely froze when I heard this question

1. Forgetting the photo

Don't forget to upload a nice, professional photo of yourself.

"You're seven times more likely to have your profile viewed if you have one," Williams says. "Like a house that's for sale, the assumption is that if there's no photo, something's wrong."

Get the picture?

2. Collecting random connections

"People think that LinkedIn is like Twitter, where it's about quantity over quality, but you're supposed to be building valuable professional relationships to leverage into career opportunities," Williams says.

She advises people to focus on honing strong connections by crafting personalized connection requests.

3. Being too obvious

Williams says to avoid letting your current boss catch you fishing for new opportunities on LinkedIn.

"A telltale sign to an employer that you’re leaving is that you overhaul your profile, connect with recruiters, and have an influx of new people," Williams says. "You can tailor your settings so that your boss doesn’t see that you’re looking for opportunities." 

The filmmakers behind "Despicable Me" seem to have another hit on their hands with "The Secret Life of Pets," in which Louis C.K., Eric Stonestreet, Kevin Hart, Jenny Slate, and Lake Bell voice lovable pets in a cute story that shows what really happens when they are home alone.

With a 75% rating on Rotten Tomatoes and a projected weekend gross of over $70 million, this is the latest proof that animated movies are the hit genre of the summer.

Here's why critics think you should spend your money on the movie this weekend.

If you're a pet lover, this one is for you.

For many of us, the closest way to our hearts is through our pets. And this movie knows exactly what we want.

"There are some funny-sweet observations about pets and our projections on to them,"Time Out wrote.

"Animals snuggling on beds or rolling over for belly rubs, stern humans turned suddenly goofy as they make faces at their goldfish or embrace their squirming gerbils. They're not exactly the scenes-from-a-marriage sequence from 'Up' – but they are awfully sweet," NJ.com said.

It's 'Toy Story' for pets.

Two pets are mistakenly taken by animal control and it's up to all their pet friends to save them before their owners get home. Yeah, sounds pretty much like a "Toy Story" plot.

Empire has some other examples: "... from the colorful characters in the group they leave behind, to the murderous villains they encounter, and even the idea their owners are unaware of their secret lives." 

However, Variety notes, "The formula may be familiar, but the personalities are completely fresh."

It's not a Pixar movie, and that's okay.

With all this "Toy Story" talk, it should be noted that this is not a Pixar movie, though it seems the filmmakers used the same playbook.

NPR wrote that the movie "has recognized a winning formula and followed it appealingly, with brightness, pace, and a fusillade of slapstick and verbal gags."

"... it feels like they’ve finally cracked the code on making a silly-animals movie that’s just deranged enough to keep you watching, yet harmless enough not to truly offend anyone," the Village Voice wrote.

Buying things you can't afford

Living above your means is a surefire road to financial stress — and even if you start earning more or get a hefty raise, don't use that as justification to give yourself a lifestyle raise.

"I didn't buy my first luxury watch or car until my businesses and investments were producing multiple secure flows of income,"writes self-made millionaire Grant Cardone at Entrepreneur. "I was still driving a Toyota Camry when I had become a millionaire. Be known for your work ethic, not the trinkets that you buy."

Thinking you don't deserve to be rich

"The average person believes being rich is a privilege awarded only to lucky people," self-made millionaire Steve Siebold writes at Business Insider. "The truth is, in a capitalist country, you have every right to be rich if you're willing to create massive value for others."

Start asking yourself, "Why not me?"he encourages. Next, start thinking big. Rich people set their expectations high. Why not $1 million?

Relying on one stream of income

"Self-made millionaires do not rely on one singular source of income,"Thomas C. Corley, who spent five years studying rich people, writes in "Change Your Habits, Change Your Life."

"They develop multiple streams. Three seemed to be the magic number in my study ... Sixty-five percent had at least three streams of income that they created prior to making their first million dollars."

Examples of these additional streams are real-estate rentals, stock market investments, and part-ownership in a side business.

Five police officers died and seven others were wounded in a shooting at a rally in Dallas on Thursday night.

It was the deadliest day for US police officers since the 9/11 attacks in 2001.

So far, the victims identified include a newly married husband who trained police in Iraq and Afghanistan, and the father of a 2-year-old who also served in Iraq.

This post will be updated as we learn the identities of the remaining victims.

SEE ALSO: One of the main suspects in the Dallas police shootings has reportedly been identified

Patrick Zamarripa, 32

Patrick Zamarripa, 32, had served three tours in Iraq before he was killed in Dallas on Thursday night.

Zamarripa's father, Rick, posted on Facebook that his son was involved in the attack:

"My son is a police officer in Dallas," he wrote. "I'm still at the hospital here in Parkland Hospital to see him be moved to the medical examiner's office ... need prayers to get through this."

According to The Washington Post, Rick had been watching TV when he heard about the shooting. He texted his son to see if he was safe, but never got a response.

Zamarripa had joined the Dallas Police Department five years ago, his father said. He was married and had a 2-year-old daughter, Lyncoln.

Brent Thompson, 43

Brent Thompson, 43, was a Dallas Area Rapid Transit officer. He was the first officer in that agency to be killed in the line of duty.

"Brent was a great officer," James Spiller, police chief of DART, told CNN. "He was an outstanding patrol officer as well as a rail officer. We have the highest respect for him."

Thompson previously worked for a security firm, and he helped train police in Iraq and Afghanistan. Justin Barnes, who served with him, posted a tribute on Facebook:

"Brent was a great man, he was the glue that held us together on many occasions, he kept the peace amongst us, always willing to give you anything he had, always willing to talk and make you feel better. Calm, cool, collected — a true professional."

Two weeks before his death, Thompson married a fellow DART officer. He was also a father and grandfather from a previous marriage.

Michael Krol, 40

Michael Krol, 40, had always wanted to be a cop. Eight years before his death, he moved more than 1,000 miles away from his home in Michigan to become a Dallas police officer.

"He was a big guy and had a big heart, and he was a really caring person and wanted to help people," his brother-in law, Brian Schoenbaechler, told The Washington Post. "It doesn’t seem real. His mom's had a difficult time."

Previously, Krol had worked as a security guard at a Michigan hospital and in the Wayne County jail system. According to his family, he loved to protect people.

"I had the honor of working with Officer Krol at Division 3 in 2003," Radken Smith, a former colleague, wrote on Facebook. "He was not only a good officer, but a good person."

NOW CHECK OUT: 15 impressive students at MIT

Aashna Mago is a virtual-reality aficionado who's interning at Oculus this summer.

Class of 2017

Major: computer science

By the time she entered her freshman year at Stanford, Aashna Mago was a budding molecular biologist who'd spent several years doing research in cancer treatments at Princeton. But Mago had a change of heart when she got to Stanford and set out to learn about programming and technology and teach herself how to code.

She landed a summer internship with virtual-reality expert Mark Bolas in the Mixed Reality Lab at USC's Institute for Creative Technologies, where she honed skills in programming, 3D modeling and printing, and design.

Halfway through her sophomore year, Mago took a leave of absence from Stanford to accept a full-time position at Rothenberg Ventures, where she helped launch an in-house production studio and run the first batch of River, the world's first VR/AR accelerator.

Since returning to campus last fall, Mago has earned a Women in VR scholarship from Oculus and VR Girls; cohosted a large-scale Women in VR event in San Francisco to encourage women from diverse industries to get involved in VR; and founded Rabbit Hole VR, a group at Stanford focused on bringing more diversity to the VR community through innovative storytelling. This summer, she'll be a software engineer at Facebook-owned Oculus.

Aashna Shroff founded a coding camp for girls in India.

Class of 2017

Major: computer science 

Growing up in India, Aashna Shroff was one of two girls in her high-school computer-science class. When she arrived at Stanford, Shrof was impressed by the initiatives to get women involved in computing fields, so she decided to take those ideas back to India by founding Girls Code Camp (GCC).

Last summer, Shroff led the GCC team of Stanford students to India to teach computer-science workshops to more than 500 middle- and high-school girls. The subsequent "GCC Hack Day" produced projects ranging from medical-emergency apps to educational games.

Shroff is also championing gender diversity on campus. This quarter, she'll be doing research with Stanford's Clayman Institute for Gender Research to help detect unconscious bias in job descriptions. And she's a mentor for Girls Teaching Girls To Code, a program that teaches Bay Area high-school girls how to code.

Shroff also contributed to research at Stanford's Bio-Robotics lab on a project that allows surgeons to practice brain surgery on virtual patients. She used cutting-edge technology to create a program where sights, sounds, and forces of the virtual surgery replicate that of the operating room.

Brandon Hill is the student body vice president and a former White House intern.

Class of 2016

Major: political science, African/African-American studies 

The summer before he was set to start at Stanford, Brandon Hill was de-accepted by the university for a bad grade in physics. He decided to take a year off — something he later dubbed "Year On" during a TEDx talk — to travel more than 30,000 miles across the world on a full scholarship through Semester at Sea.

He made it to Stanford and is now vice president of the school's more than 16,000 undergraduate and graduate students. 

Hill is passionate about helping youths of color maximize their creative potential through his startup, Enza Academy. Over the last two years, Enza has trained more than 150 kids nationwide at its innovation, tech, and entrepreneurship "hack-camps," which have been sponsored by Google, Stanford, Columbia University, and Facebook. Last December, Hill and his cofounder spoke about Enza Academy at the White House, where Hill interned the summer after his freshman year at Stanford.

He's also interned at Google on the YouTube star-management team, at UNICEF in Tanzania, and for the US Department of Education. When he graduates in June, Hill plans to work full-time on his "TED meets Twitter" idea-sharing platform.

So, here's the thing. While Netflix may be one of the greatest time-killers known to humankind - and possess a near superhuman ability to keep you watching just one more episode of “Fuller House”, a full two hours after you meant to go to bed - it's also inherently limited in its scope. With licensing deals being what they are (incredibly tough to negotiate and often extraordinarily complicated), even Netflix's thousands-strong back catalog is a drop in the ocean compared to the number of films and TV shows that could theoretically be on there.

Added to which, there are certain movie franchises that Netflix simply can't show, because their streaming rights are exclusively held by other companies.

Which is why - despite Disney's recent deal to stream all its newly released movies on Netflix - it's extremely difficult to find any Marvel movies on the service. And, so, as a result the five best Marvel movies on Netflix aren't really what you'd expect.7

Or, at least, they aren't if you live in the US. Had you moved to Canada by now, you could absolutely be watching a Captain America or Avengers movie right now, much as UK residents could be enjoying Thor's MCU-based adventures at this very second.

Instead, though, US Netflix users are limited to...this lot. First up:

5. Marvel's Iron Man & Hulk: Heroes United (2013)

So, on the one hand, "Marvel's Iron Man & Hulk: Heroes United" is the Science Bros. movie you've always dreamed of, in the sense that it's a movie starring Iron Man and The Hulk. On the other hand, it's a straight to DVD animated movie with Cartoon Network-level graphics. And no Robert Downey Jr or Mark Ruffalo.

So watch it, sure - but maybe keep hoping to see Hulk turn up in "Iron Man 4", too.

4. Marvel & ESPN Films Present: 1 of 1: Genesis (2014)

Yup, that's right. This is a documentary, made by ESPN, about Marvel Comics. Or, rather, it's a documentary made by ESPN about the links between top level athletes and the Marvel universe's greatest heroes.

Also, it features Tony Hawk, which is a way bigger deal if you grew up in the early 2000's (doubly so if you owned Tony Hawk's Pro Skater on the PS1).

3. Iron Man & Captain America United (2014)

Remember how "Marvel's Iron Man & Hulk: Heroes United" featured Iron Man and the Hulk, only not quite how you remember them from the movies? Well, "Iron Man & Captain America: Heroes United" offers pretty much the same experience, only with added Captain America.

In other words? It's not quite "Captain America: Civil War".

Over the past few decades, life and business strategist Tony Robbins has become a household name.

1. Have a mission

For people who find themselves in a rut, or who are unsure of which steps to take to improve their lives, finding a focus is important. However, it’s equally important to find the right focus for your life.

"Energy comes from having a mission; it comes from something that you’re being pulled by, not something you're pushing on," Robbins told well-known business expert Marie Forleo in a one-on-one interview. "If there’s something that you’re made for, then there’s a level of energy that most people would never dream of ... We all have that, but most of us don't connect to it and unleash it."

Robbins said he lives in this mindset each and every day. In order to apply this to your own life, it’s important to spend time thinking about what you’re really passionate about, whether it’s big or small. The more excited and the more passionate you are about your goals in life, the more powerful you can be.

2. Stop trading time for money

When it comes to walking the path to financial freedom, Robbins frequently talks about the issue of trading time for money. "If you work for a living, you're trading your time for money," he wrote in an article for Entrepreneur magazine.

"Frankly, it's just about the worst trade you’ll ever make in life: You can always get more money, but you can't get more time," he wrote. "In the end, it doesn't matter how much money you earn. If you don't set aside some, you could lose it all ... This is the first and most important step in putting yourself on the road to financial freedom. Take that step today."

In essence, you can’t quit your job today, but you can start saving today. If there is a business you want to start or something you want to spend all your time doing, he advised to start saving now. The more money you save, the faster you can focus on the things you want to spend your time doing.

3. Practice gratitude

This is sometimes an easily overlooked step, especially in difficult times. However, it can have a great positive impact on your life when you follow it.

In his book, "MONEY Master the Game," Robbins quoted Sir John Templeton, whom he called one of "the greatest investors in history." In an interview with marketing expert Lewis Howes, Robbins said Templeton told him: "If you have nothing, but you're euphorically grateful for whatever you have, you're the richest person you're ever going to know."

Robbins said he makes gratitude a part of his morning routine. Every morning, he spends some time thinking of the things in his life that he is grateful for, which helps him start his day. Anyone can start this practice, and the great thing is that it’s simple. To keep things consistent and make this a habit, you can even start a gratitude journal.

The US isn't the only country that received the world's latest supersonic stealth strike fighter jet.

The UK's Royal Air Force and Royal Navy have planned to acquire 138 models of the much talked about F-35B Lightning IIs from Lockheed Martin by 2018. Having these F-35Bs would allow the UK to enhance their carrier-strike capabilities with their two new aircraft carriers that were specifically designed to integrate with the unique planes. 

In order to get acclimated with the jet, UK pilots have begun training with their counterparts across the pond. Taking off from RAF Fairford in Gloucestershire, England, a UK pilot embarked on the transatlantic crossing with the F-35B, while accompanied by two of the US Marine Corps' F-35Bs.

Here are the pictures of the F-35Bs in flight:

What is power? And how do you acquire it?

Robert Greene, author of "The 48 Laws of Power," has some insight.

Power is "the measure of the degree of control you have over circumstances in your life and the actions of the people around you,"Greene tells Business Insider. "It is a skill that is developed by a deep understanding of human nature, of what truly motivates people, and of the manipulations necessary for advancement and protection."

Greene gave us permission to republish his 48 laws power, which he developed from analyzing some of history's most powerful people.

Never outshine the master.

"Always make those above you feel comfortably superior. In your desire to please or impress them, do not go too far in displaying your talents or you might accomplish the opposite — inspire fear and insecurity. Make your masters appear more brilliant than they are and you will attain the heights of power."

Never put too much trust in friends; learn how to use enemies.

"Be wary of friends — they will betray you more quickly, for they are easily aroused to envy. They also become spoiled and tyrannical. But hire a former enemy and he will be more loyal than a friend, because he has more to prove. In fact, you have more to fear from friends than from enemies. If you have no enemies, find a way to make them."

Conceal your intentions.

"Keep people off-balance and in the dark by never revealing the purpose behind your actions. If they have no clue what you are up to, they cannot prepare a defense. Guide them far enough down the wrong path, envelop them in enough smoke, and by the time they realize your intentions, it will be too late."
