General Electric chief marketing officer Beth Comstock is no stranger to travel, but it wasn't always something she looked forward to.

The road warrior spends about 50% of her time away from home in New York City, traveling often to GE corporate headquarters in Fairfield, Connecticut, and flying to San Francisco several times a month to oversee GE Ventures, the company's startup investment arm. She also travels internationally about once every quarter.

Early in her career, Comstock was afraid of flying. That started to change, though, once she figured out how to use her flights to be productive.

Today, the veteran executive has come to see her time in the air as a blessing in disguise — an opportunity to disconnect, recharge, and do creative work.

"It's turned out to be a place where I'm not just productive, but creative," says Comstock, who became GE's chief marketing officer in 2003. "You say, 'Wow, I'm above the Earth. I'm in this amazing place.' You look out the window, and your mind just wanders."

To get the most out of every flight, Comstock likes to plan what she is going to get done beforehand.

If she's traveling on a 13-hour flight to Asia, for instance, she'll think about the work she would like to do and how much sleep she wants to get, scheduling the most meaningful work for the beginning of the trip.

Comstock works in two-hour cycles before taking a break, which she often uses to do some reading.

This past summer, she was "totally obsessed" with Norwegian novelist Karl Ove Knausgård's "My Struggle" series. More recently, she has read "Essentialism: The Disciplined Pursuit of Less" by the business writer Greg McKeown.

At 36,000 feet, Comstock's favorite kind of work to do is writing — which she does by hand — because the isolation gives her time to reflect that she often doesn't get when she's on the ground.

On every flight, she brings a big stack of paper and a nice pen to write anything from a LinkedIn post she's been thinking about to a strategic business plan for the company's advanced manufacturing division.

Comstock says most businesspeople today have what she calls "pajama jobs."

Because most businesspeople today have what she calls "pajama jobs," requiring them to join conference calls at all hours, flying is a time to disconnect.

By that she means global positions that occasionally require them to join a conference call in their pajamas. That's why it's especially important to carve out time to think without being interrupted by a text message or email.

"Wi-Fi on planes can be really great, but I rarely use it because it is a distraction," she says. "Trying to find these moments wherever you are to unplug and be creative is essential, both as a businessperson and as a person."

During the latter half of an international trip, Comstock makes time to get about three or four hours of sleep. After she wakes up, she likes to watch something on her iPad before reading a novel or catching up on email.

And when the plane touches down, she's able to leave with the knowledge that she has made the most of her travel time.

"In business, flying is a fact of life. Few of us really like it, I think it's fair to say," Comstock tells Business Insider. "I had to overcome a lot to get to the point where I look forward to a flight and use it to spur creativity."

It's not just great drinks that make a great bar — it's also great service, great ambience, and fair prices that complete the experience.

We looked at six notable bar rankings compiled by critics and experts and aggregated the rankings to come up with our own list of the Best Bars in America.

The rankings we used were James Beard Foundation's 2014 Restaurant and Chef Award Semifinalists for Outstanding Bar Program; Esquire's Best Bars in America; Food & Wine's Best Bars in America; Zagat's Hottest Bars in 15 US Cities; The World's 50 Best Bars from Drinks International; and Liquor.com's Best Bars in America.

We gave each bar a numerical rating based on how many lists the bar appeared on and how high it appeared on lists that were ranked. We used the number of five-star Yelp ratings as a tiebreaker, where a bar with more five-star Yelp ratings outranked another bar when a tie occurred.

You can read more about our methodology here.

18. Attaboy

New York City

When the cultish speakeasy Milk & Honey moved in 2012, it left behind two expert bartenders, Sam Ross and Michael McIlroy, who opened Attaboy in early 2013.

This menuless, Lower East Side cocktail bar maintains the same expertise in all things liquor and even more secrecy than its predecessor: It has no website and no telephone number, and it serves beer, wine, and bartender's choice drinks on a first-come, first-serve basis.

17. Death & Co.

New York City

Death & Co. is a well-hidden gem on the border of the East Village and Alphabet City serving gourmet cocktails — both entirely from-scratch innovations, and ones that take liberties with the classics.

Not many people used to know about Death & Co., but the secret's out, and now cocktail enthusiasts are prepared for the long wait, especially on weekends, for Dave Kaplan and Ravi DeRossi's award-winning menu.

16. The Broken Shaker

Miami Beach, Florida

Elad Zvi and Gabriel Orta, the owners of the beverage program company Bar Lab, collaborated with the Freehand Miami hotel to open James Beard Award-nominated bar The Broken Shaker.

The bar puts a little bit of Miami in everything it does, from the tropics-inspired drinks on the menu to the service, which extends out into the Freehand's oasis-like outdoor patio.

We recently published our list of the Best Bars in America. 

To create this list, we looked at six notable bar rankings compiled by critics and experts and aggregated the rankings to come up our own list.

The rankings we used were James Beard Foundation's 2014 Restaurant and Chef Award Semifinalists for Outstanding Bar Program; Esquire's Best Bars in America; Food & Wine's Best Bars in America; Zagat's Hottest Bars in 15 U.S. Cities; The World's 50 Best Bars from Drinks International; and Liquor.com's Best Bars in America.

We valued the James Beard awards the most highly, due to the prestige of the honor, awarding bars that appeared as semifinalists on this list with a score of 0.75.

Each time a bar appeared on Esquire's list, it received a score of 0.55. Bars that appeared on Food & Wine's list each received a score of 0.5. Bars that appeared on Zagat's Hottest Bars list and Liquor.com's list each received a score of 0.25 and 0.15 respectively.

For The World's 50 Best Bars list, which was ranked 1 to 50, we calculated the score by using a formula that factored in the rankings, assigning a maximum total of 0.75 points to each bar with higher scores going to higher-ranking bars.

We then tallied up the scores to create the final ranking. Based on these calculations, the highest possible score would be 3.67 if a bar appeared on every ranking — but since none of them did, the highest score (2.1) belonged to The Dead Rabbit in New York City.

We used the number of five-star Yelp ratings as a tiebreaker, where a bar with more five-star Yelp ratings outranked another bar when a tie occurred.

With more than 7 million subscribers and 1 billion views, hair-and-makeup guru Michelle Phan is a certified YouTube superstar. 

Young people love Phan for her friendly, relatable persona, and she's landed national advertising deals with big brands like Lancome and Diet Dr. Pepper.

And as of this week, she's now a published author. Phan's book, "Make Up: Your Life Guide to Beauty, Style and Success — Online and Off" was released by Penguin Random House's Harmony Books this week.

Phan was in New York City last night to do a book signing at the Strand's Club Monaco store. Business Insider stopped by to check out the scene.  

The signing event was limited to the first 250 people, and a line had already formed when we arrived an hour early.

You had to have a copy of the book to get in, and people — mostly young girls — lined up to make their purchases. One girl briefly held up the line when she used a bag of quarters to pay for her copy of the book. 

Since the event was limited capacity, everyone who purchased a book got a little ticket for entry. 

A group of girls proudly show off their new purchases.  

Amy and Yuriya are both 16, and they've been big fans of Phan for years. 

"There's that phase where we all kind of want to be famous on YouTube," Amy told me. "I was looking around for makeup tips and found her videos." 

They're here on a visit from Japan, and decided to check out the signing after they saw Phan post about it on Instagram. 

When I asked what they like about her, they say a big reason is that she seems so nice. "I like her voice — it's so soothing," Yuriya said. 

Madness erupted when someone came around to give away samples from Em, Phan's cosmetics line.

Phan started signing books at 6:00. By 6:30, the line had moved a few feet forward. 

Fifteen minutes later, we reached the entrance to the room where Phan was signing books. A girl behind me screamed, and people started reaching their phones up to get pictures.

A girl in front of me in line told me she had met Phan once before, at her pop-up makeup shop in New York City's SoHo neighborhood. 

"The first time I saw her, I cried," the girl told me. 

Phan took the time to chat with each of her fans. 

And plenty of selfies were taken. 

I talked to a 13-year-old named Eveline, who said she had been watching Phan's videos for about four years. She quickly took a selfie with her new book and posted it to Instagram. She turned to her mom excitedly: "Oh my God, what if she likes it?!"

Cooks and foodies love to argue about the best way to thaw meat.

Sure, you could take frozen meat out of the freezer and leave it in the fridge to thaw for 24 hours, but that requires almost a superhuman-level of foresight.

For faster results, some people prefer to defrost with cold water in a bowl. Others say that hot water is the way to go. Still others argue that the microwave can work as long as you don’t overcook the meat.

Luckily, there’s another way to quickly thaw meat, and all you need are two large aluminum pots, room temperature water, and a bag for your meat.

Spotted on CTi News, a Taiwanese cable TV network (via Women’s Health Mag), the idea is pretty simple. Turn one of the pots upside down and place the meat in a bag on top. Next, fill the other pot with room temperature water and put it on top of the steak. 

That’s it. In roughly 10 minutes (depending on the thickness of the steak), your meat will be thawed. 

The reason this works is because the weight of the water presses down on the steak — increasing its surface area — while the temperature of the water is conducted by the aluminum, thus speeding up the thawing process.

Watch the video to see it in action.

McDonald's has been taking a lot of heat in the past couple of weeks concerning the quality of its food.

But when food experts were unknowingly served McNuggets and Big Macs at a catering conference in The Netherlands, their reactions were surprisingly positive.

Two guys behind the YouTube channel lifehunterstv sliced McDonald's McNuggets and burgers into bite-size pieces and served them with toothpicks on a white platter. They told the conference attendees that the food was a sampling from their "high-end" restaurant's menu. 

Here's what it looked like:

One attendee called the food "nice and firm" and said it had "a good bite."

Another said it "rolls around the tongue nicely," and "if it were wine, I'd say it's fine."

The food was also described as "delicious" and "rich."

Live-action role-playing (or LARPing) was born on the fringes of American pop culture, a descendant of much-maligned hobbies like Dungeons and Dragons and other table games. 

In LARPing, players spend their weekend dressing up in costumes, adopting elaborate personae, and inhabiting a complex imagined world. 

The hobby, like most of "nerd" culture, has become increasingly mainstream.

Across the US, Canada, and Europe, LARPing groups are everywhere. There are more than 30 LARPing organizations in the US, each of which has tens of chapters and thousands of members.

A few weeks ago, we visited Alliance, one of the oldest live-action-role-playing groups in the country, in central Pennsylvania, to figure out what LARPing is all about. 

To learn more about Alliance, check out their website.

Faire Play, Alliance's headquarters, is a massive barn in Central Pennsylvania. We arrived early Saturday morning just as the LARPers at Alliance were waking up. The players were shaking off a long night. Most had arrived in costume on Friday night and played until nearly dawn.

Most of the players were filing into the "tavern," a large room built into the center of the barn. Everyone was waiting in line for eggs, bacon, pancakes, and coffee. Players pay $60 to spend the weekend at Alliance, which covers lodging and meals.

The Alliance headquarters is located on a sprawling 42-acre property. In addition to the tavern, the central barn has bedrooms for players and a backroom full of costumes, weapons, and other assorted LARPing detritus. The back lawn serves as the main battleground and is sprinkled with cabins for players to sleep in.

When we first laid eyes on the mythical "Sushirrito" on Reddit, it seemed too good to be true: a sushi roll swollen to the size of a burrito, stuffed with veggies, sauces, rice, and raw fish, and eaten with your hands.

"Mutant foods" appear to be all the rage right now, from Dominique Ansel's cronut to Keizo Shimamoto's Ramen Burger. San Francisco-based Sushirrito, which serves a "sushi burrito" is a natural evolution of that trend, one born from necessity.

Years ago, founder Peter Yen worked downtown in San Francisco and found himself craving sushi for lunch, but did not have time for a sit-down meal. Nagged by a growing concern about overfishing that was decimating the seafood population, Yen began to dream up a new way to consume sushi that was fast, fresh, affordable, portable, and environmentally conscious. The sushi burrito was born.

We stopped by Sushirrito's Union Square and FiDi locations in San Francisco to try the latest culinary phenomenon.

Around noon at the FiDi Sushirrito, the line was out the door and barricaded by ropes, as if hungry patrons were clamoring to get into the hottest club.

We ate at the Union Square location. Inside, diners queued up in front of the glassed-in food prep area. You can't customize what goes inside your sushi burrito, unlike other specialty quick-service restaurants such as Chipotle or Chop't. The menu consists of eight varieties, ranging from $9 to $13. 

It's rather mesmerizing to watch the sushi burrito come together. Like a normal sushi roll, a plastic-bamboo mat is used to tuck the ingredients into a pinwheel. The employees seem to have it down in seven seconds or less.

I ordered the Sushi Samba ($10), because cooked salmon seemed like a safe bet for a first-time sushi burrito eater. It arrived wrapped in paper and nestled inside a takeout box, which I learned was completely necessary in order to catch rice droppings.

The Sushi Samba contains agave-soy salmon from British Columbia, tempura asparagus, Namasu cucumber, butter lettuce, avocado, pumpkin seeds, wasabi dust, and a generous drizzling of Teriyaki mayonnaise. As you can see, it barely fit in one hand.

Business Insider's senior West Coast tech editor Karyne Levy ordered the most popular menu item, according to a Sushirrito manager. The Geisha's Kiss bundles raw yellowfin tuna caught by hand-line, tamago (a type of Japanese omelet made of layered cooked egg), spicy piquillo peppers, yuzu Tobiko (flying fish roe, or caviar), lotus chips (a crunchy and baked root vegetable), Namasu cucumber, butter lettuce, and avocado.

Though it takes the shape of a burrito, the sushi burrito definitely tasted like a fresh sushi roll. It was served chilled, for one thing. And each bite offered a distinct flavor and texture. The oven-baked salmon fell apart in my mouth, the pickled cucumbers burst with juiciness, and the rice and avocado provided a welcomed blandness.

The sushi burrito wasn't the easiest food to wolf down, however. "The seaweed wrapper started breaking down almost immediately," my coworker Levy noted. "But it's cool, that's why forks are available."

Both sushi burritos packed a generous amount of fish in them, which was good and bad. They tasted sinfully delicious and fresh, without forcing us to fork over a ton of cash; but four hours later, I felt sickly stuffed.

Would I eat it again? One-hundred percent yes.

Here's hoping Sushirrito lands in New York City soon.

Winter is coming.

The morning jog that you dutifully developed over the past few months is about to be put to the test.

Instead of the bright summer sun meeting you in the morning, you'll be greeted by the relentless autumn wind. 

Yet you know that fitness has tremendous effects on at-work performance, since you read about how marathon-running CEOs lead companies valued 4% to 10% higher than CEOs who don't run marathons.  

But running in the cold is way less fun, so how can you protect that habit? 

We consulted Walter Mischel, the Columbia University psychologist whose work has helped psychological science understand how self-control predicts success.

I told him that my editor made a special request for our interview — she wanted to know how she could keep running even when things got blustery. 

Mischel, author of "The Marshmallow Test: Mastering Self-Control," said the first step is understanding what's going on. 

"What is happening is that the pleasure value of jogging is going down and the effort value and the discomfort value of jogging is going up," he said. "She has to ask herself, 'How much is this really worth to me?'"

If it is worth the while, the next step is implementing an "if/then" plan.

"She has to heed the delayed consequences," Mischel said. "When it's 7 a.m. and the alarm rings, I put on my warmest jogging clothes, and I go." 

And if that pattern is put in place every morning, it becomes a normal part of the day.

"If she's serious about it, then she makes an if/then plan," Mischel said. "It's like jumping in the shower, even though you don't feel like it — it's automatic." 

You take the decision away, and thus achieve a sustainable habit.

So it's only fitting that another famous face is the newest addition to the star-studded condominium — namely, Jennifer Lopez. 

Lopez has bought the incredible 6,500-square-foot penthouse that overlooks Madison Square Park for $22 million, according to real estate website Zillow. 

The pre-war condominium has four bedrooms, six bathrooms, and four separate terraces with a grand total of 3,000 square feet of exterior space.

It even has a full-time doorman, gym, private storage, and key-locked elevators with private elevator landings. 

Douglas Elliman has the listing. 

Welcome to The Whitman at 21 East 26th Street. This luxurious complex has a full-time door man for its four apartments.

The enormous living room has arched windows that look right out onto Madison Square Park.

The kitchen was designed by famed Italian design company Arclinea.

It's starting with watches and phones, and moving on to everything in your home. The so-called "internet of things" is all about electronically connecting everything together.

Wellington (AFP) - A photographic notebook from Robert Scott's ill-fated Antarctic expedition has been found after a century trapped in the ice of the frozen continent, New Zealand's Antarctic Heritage Trust said.

It belonged to scientist George Murray Levick and was discovered outside Scott's 1911 Terra Nova base during last year's summer ice melt.

Writing in the notebook remains legible but the binding has been dissolved by years of ice and water damage, the trust's executive director Nigel Watson said.

"It's an exciting find. The notebook is a missing part of the official expedition record," he said.

"After spending seven years conserving Scott’s last expedition building and collection, we are delighted to still be finding new artefacts.”

He said the pages of the notebook were taken to New Zealand and individually preserved, then given new binding and returned to Antarctica, where the trust is working to preserve five sites used by explorers Scott, Ernest Shackleton and Edmund Hillary.

Scott's expedition split into two groups after reaching the Antarctic, with the leader's contingent reaching the South Pole on January 17, 1912, only to find Norwegian Roald Amundsen had beaten them there a month earlier.

Scott and his companions later died of exposure and starvation.

Levick was in the other group, which travelled along the coast to make scientific observations but became stranded from the base camp when pack ice prevented their ship from picking them up.

The six men all survived the Antarctic winter by digging a cave in the ice and eating local wildlife, including penguins and seals.

Other discoveries made by the trust include bottles of whisky taken on Shackleton's 1908 expedition and lost negatives from his 1914-17 foray to the Ross Sea.

The contents of Levick's notebook are fairly mundane, comprising the dates, subjects and exposure details of photographs he had taken.

Much more interesting was a scientific paper he wrote titled "Sexual Habits of the Adelie Penguin", which was lost until researchers at London's Natural History  Museum rediscovered it in 2012.

In it he records observations of the penguins' "depraved" habits, including homosexual behaviour and males trying to mate with the bodies of dead females.

Levick was so horrified at the penguins' antics that he wrote down some of his observations in Greek so the average reader could not understand them and his paper was never publicly released.

If you watch this video, you're going to hear a lot of F-bombs being dropped by little girls in princess dresses. 

But they're not here to prove the word "f---" is the worst word they can say — try "pay inequality" or "rape and violence."

A new video, sponsored by FCKH8.com, a for-profit site that promotes feminism and marriage equality, uses these little girls to sell a new line of shirts for women's rights with sayings like "girls just wanna have fun-damental rights" and "this is what a feminist looks like" printed on them.

The video is hard to ignore.

"I'm not some pretty f---ing princess!" the girls yell. "I'm pretty f---ing powerful!"

"What's more offensive?" they ask. "A little girl saying f---? Or the f---ing unequal and sexist way society treats girls and women?"

It's pretty f---ing powerful.

A new study by Airlines Reporting Corporation (ARC), a company that analyzes airfare data, shows the best time to book a flight is actually on Sunday, The Wall Street Journal reported.

The previous school of thought was that Tuesday was the best time to book a flight, but ARC disputed that theory.

ARC analyzed both US domestic and international airfares between January 2013 through July 2014, and found that the lowest average airfare was available on Sundays. Travelers who booked flights on Sundays paid an average $432 for domestic flights and $958 for international flights. 

The Wall Street Journal posited a theory behind this: that "airline executives come into work Monday looking to raise fares, not discount them with sales to fill seats."

Here's a chart showing the average airfares for U.S. domestic flights:

And this chart shows the average cost of international airfares: 

The study also found that travelers secured the best airfares when they booked their flights 8 weeks in advance. Read more of the results here.

Mark Zuckerberg took the stage at Tsinghua University in Beijing on Wednesday.

To the delight and amazement of the crowd, he spoke in Mandarin Chinese. 

"I'm very glad to be in Beijing," he said to the group. "I love this city. My Chinese is really a mess, but I study using Chinese every day." 

Students and faculty cheered, the New York Times reports. 

The Facebook CEO was holding court in Beijing because he just signed onto the advisory board of Tsinghua University, which is basically the Yale of China.

In a half hour talk — which you can watch in the video below — Zuckerberg talked about what Facebook is doing in China, his view of Chinese innovation, and why he is studying Chinese. 

First off, his wife Priscilla Chan's family speaks Chinese. Evidently her grandma was "very shocked" when he told her in Chinese that the two of them were getting married. 

On the business end, he says that studying Chinese helps him to understand the culture.

Facebook has long sought to break into China and get to its 1.3 billion citizens, 45.8% of whom are currently internet users, a number that's going to continue increasing. But China keeps Facebook, Twitter, and their peers out of the country for fear of how social networks might spur unrest. 

The Times reports that when Zuckerberg was asked what Facebook's plans for China were, he took two big gulps of water before providing a response. 

"We're already in China," he said, cracking up the room. "We help Chinese companies increase foreign customers; they use Facebook ads to find more customers." 

There is one last reason he's studying Mandarin. 

"I like challenges," he said.

Considering the achievements of the 30-year-old billionaire, this isn't too surprising and may reflect the psychology behind his success. The fact that Zuckerberg is studying Chinese — a notoriously difficult language to pick up in adulthood— may be an outgrowth of his mindset.

By studying the language every day, he knows that with effort he can improve. That growth mindset— where you take effort, rather than talent, to be the driver of your progress— has been identified by developmental psychologist Carol Dweck as a predictor of success in relationships, academics, and business. 

Here's the video.

If you've ever dreamt of brushing your teeth with a gold toothbrush, a titanium toothbrush is probably the next-best thing.

Retailing for $4,200, the Reinast Luxury Toothbrush is the most expensive toothbrush on earth.

And it's not even electric.

So what makes it so special? The company claims that its design, durability, and specially trademarked anti-bacterial coating make it worth the hefty price tag. 

This is not the type of toothbrush you would throw away either. Instead, the bristle head detaches from the metal base so you can ditch it and replace it.

The brush comes with a free three-year service plan of new bristle heads every six months (a service that is "naturally at no charge," according to the website). After that, Forbes reports that the plans get a bit more expensive: $400 for five years, $800 for seven years, or $1,600 for 11 years.

All for a toothbrush.

"The type of client we have in mind and are currently selling to are those with an incredibly high net-worth,” Chief Technology Officer Dr. Djorde Djokovic explained to Gizmodo. “It’s for people who can spend this amount of money on a product they deem beautiful. And one that doesn’t exist on the market elsewhere.”

And it turns out, some billionaires are surprisingly willing to shell out $4,200 on a toothbrush. Djokovic told Gizmodo that at least one Middle Eastern sultan gives them out as gifts. 2 Chains also seemed to like it when he tested the Reinast Luxury Toothbrush for his Expensivest series with GQ.

And for those billionaires who don't prefer the taste of metal in their mouths in the morning, Reinast also offers "bumpers" to cover the brush end of the tool for that familiar plasticky feel — because you should always have the option of feeling like you're brushing with a $10 toothbrush with your $4,200 toothbrush.
