In today's world, when you have a lyric stuck in your head but don't know the song it comes from, the answer is just a quick search away. 

Tracking this impulse, Amazon has released a list of the song lyrics that people have most frequently asked about on its Alexa devices.

"The most requested lyrics don't always correspond with the title or chorus of each song," the company notes in a release, explaining the double appearance of a certain Justin Timberlake song on its list. 

From "We all live in a yellow submarine" to "swish swish bish," these lyrics have confounded and intrigued Alexa owners enough to inquire about the songs they originate from.

Here are the 13 song lyrics that people get confused about the most, according to Amazon Alexa data:

Want an all-natural way to lift your mood, improve your memory, and protect your brain against age-related cognitive decline?

Get moving.

A wealth of recentresearch, including a new study published this month, suggests that any type of exercise that raises your heart rate and gets you moving and sweating for a sustained period of time — known as aerobic exercise— has a significant, beneficial impact on the brain.

"Aerobic exercise is the key for your head, just as it is for your heart," said an article in the Harvard Medical School blog "Mind and Mood."

Most research suggests that the best type of aerobic exercise for your mind is anything you can do regularly and consistently for 30-45 minutes at a time. But the latest study suggests that any kind of workout — whether it's for 5 minutes or 45 — can have beneficial impacts on mental health.

The new study, published in the American Journal of Psychiatry, is the largest long-term study of its kind to look at the link between exercise and mental health, with a special focus on depression.

The researchers studied close to 34,000 Norwegian adults over 11 years and had them report how often they exercised each week, how intense it was, and how depressed or anxious they felt. The results suggested that as little as one hour of exercise each week helped shield people against depressive episodes. Notably, that exercise did not need to be aerobic — even participants who got moving without becoming breathless (perhaps with an activity like a long, moderately-paced walk) were significantly less likely to report symptoms of depression compared with those who did no exercise.

Plenty of other research has revealed a powerful connection between mental and physical fitness across varying levels of intensity. Some benefits — like a lift in mood — can emerge as soon as a few minutes into a sweaty endeavor, while others — like improved memory — might take several weeks to crop up.

A pilot study in people with severe depression, for example, found that just 30 minutes of treadmill walking for 10 consecutive days was "sufficient to produce a clinically relevant and statistically significant reduction in depression." Aerobic workouts appear to help reduce levels of the body's natural stress hormones, such as adrenaline and cortisol, according to a recent study in the Journal of Physical Therapy Science.

In older people, the best way to protect against age-related brain decline seems to be aerobic workouts. A study published in May found that in adults aged 60-88, walking for 30 minutes four days a week for 12 weeks appeared to strengthen connectivity in a region of the brain where weakened connections have been linked with memory loss. And a study in older women who displayed symptoms of dementia found that sweaty, heart-pumping exercise was linked with an increase in the size of the hippocampus, a brain area involved in learning and memory.

Several studies even suggest that aerobic workouts provide the best protection against other types of cognitive decline, too. A study involving hundreds of breast cancer survivors concluded that such exercise seemed to reduce the symptoms of "chemo brain," a commonly reported side effect of cancer treatment that involves memory loss and difficulty focusing.

"The message for cancer patients and survivors is, get active!" Diane Ehlers, the lead author of that study and a professor at the University of Illinois at Urbana Champaign, said in a statement.

The best overall health results — mental and physical — for people over 50 appear to come from a combination of aerobic workouts and resistance training (strengthening work like weights or squats). That type of workout plan could be anything from high-intensity interval training, like the 7-minute workout, to dynamic flow yoga, which intersperses strength-building poses with heart-pumping dance-like moves.

Researchers still aren't sure why exercise appears to provide so many benefits to our brain and body. One factor could be increased blood flow, since aerobic work pumps fresh energy and oxygen to the brain. 

Regardless of the cause, Joe Northey, an exercise scientist at the University of Canberra, said his research suggests that anyone in good health over age 50 should do 45 minutes to an hour of aerobic exercise "on as many days of the week as feasible."

That's probably good advice for all ages.

NOW WATCH: How to do a burpee — the total-body exercise that will keep you fit for life

Melania Trump has a hurricane style routine — and it's a deft political play from the first lady. 

On Tuesday, she once again was spotted in stiletto heels as she boarded a plane to a hurricane-devastated region.

In August, the first lady was mocked for wearing sky-high stilettos as she headed to Texas following Hurricane Harvey; on Tuesday, she wore another pair of stilettos as she boarded the plane heading to Puerto Rico following Hurricane Maria.  

When Trump landed in Puerto Rico, she had changed out of her stilettos into a pair of Timberland work boots. 

She was wearing an outfit distinctly similar to the one she wore to Texas (and Florida, following Hurricane Irma): stylish, form-fitting jeans and a baseball cap. 

Some people — mostly on the left — had snarky comments about Trump's outfit (specifically, her shoe choice) on Tuesday. 

"Much the way her 'flood heels' left many feeling she was out of touch with the difficulties Texans were facing after Harvey, her white jeans may reiterate she's not here to get dirty," Cara Kelly wrote in USA Today. "These are photo op pants"

However, many others — especially supporters of President Trump — saw the backlash against Melania Trump as yet another sign of how out-of-touch the "liberal elite" and media are.

As first lady, Trump's fashion choices are deliberate and strategic. She is very aware of the message she is sending — typically, one of aspirational luxury. 

When the first lady wore stilettos heading to Puerto Rico on Tuesday, she must have known that people would react. However, left-leaning criticism wasn't necessarily a concern — proving she could rise above backlash with a wink to supporters was more important. 

And, many people saw the shoes as sending exactly that message. 

Wearing stilettos in a hurricane-devastated region would be difficult for even President Trump's supporters to encourage. However, by wearing high heels while heading to impacted areas, then switching into a stylish but more practical uniform, the first creates a win-win scenario.

Even if there is some backlash to her high-heeled fashion, the backlash is then engulfed by people set on defending the Trump administration. These defenders have plenty of ammunition thanks to the more hurricane-ready looks she dons once her plane actually lands. 

Fashion is political for the first lady — and it looks like Melania Trump has figured out how to give her base what they want.

Fashion designer Elie Tahari's Hamptons home has just gone on the market for $45 million. 

Tahari originally purchased the home for $12.1 million in 2005. The designer said in a statement to the Wall Street Journal that he's selling it because his focus is currently on his business. 

"I haven't been there for the last two summers," he said in the statement.

During one of those two summers, the Sagaponack home was rented to a hedge fund manager for nearly $800,000 for the months of July and August, the property's listing agents, Keith Green and Ann Ciardullo from Sotheby's International Realty, told the Wall Street Journal.

Jack Beaton died protecting his high-school sweetheart.

Jack and Laurie Beaton attended the Route 91 Harvest festival in Las Vegas to celebrate their 23rd wedding anniversary. They sat sipping beers and enjoying the concert on the grass.

Laurie posted to Facebook, "Here's to 23 wonderful years and looking forward to 23 more."

Less than an hour later, Laurie felt a bullet fly by her shoulder. Jerry Cook, Laurie's father, recalled a conversation with her in an interview with the Los Angeles Times.

"Jack got on top of Laurie to protect her. He laid on top of her and said, 'Laurie, I love you.' She said, 'I love you, too,' and boom — he got hit. I don't know how many times," Cook said.

Rescue workers ushered Laurie and others members of her group to safety. Jack had already been removed from the scene when she returned looking for his body.

Jack, 54, leaves behind two children, Delaney and Jake.

Marine veteran Taylor Winston stole a truck and drove dozens of people to the hospital.

When Stephen Paddock fired on a country music festival, Taylor Winston didn't run away. The 29-year-old marine veteran knew he had to help.

"People started scattering and screaming and that's when we knew something real was happening," Winston told CBS. He described the scene as a "mini war zone."

Winston, who served two tours in the Iraq War, helped toss people over a fence to get to safety. He then raced to a field of trucks parked nearby. The first one he checked had the keys in it.

He texted his friends who had set up a makeshift hospital far from the gunfire to bring over some victims, he told CNN. They squeezed into the back of the truck and the backseat.

After dropping people off at a hospital, Winston turned around for a second trip. By the end of the night, he and his friends had transported around two-dozen people to the hospital.

Jacob Shamsian contributed reporting to this post.

Dawn-Marie Gray and Kevin Gray stayed behind to save others.

When Dawn-Marie Gray and her husband, Kevin, won tickets to the Route 91 Harvest festival through a Portland radio station, they could never have known it would be one of the most harrowing events of their lives. The couple took shelter in a VIP area during the shooting.

"When we came out it was horrific," Dawn-Marie told USA Today. "A field of bodies."

Dawn-Marie, who worked as a paramedic for about seven years, knew that local paramedics would not be admitted entry until the area was deemed safe. She and her husband turned to the wounded, providing CPR, making tourniquets, and checking for pulses on lifeless bodies.

The couple worked together to load victims into cars en route to the hospital.

"It had nothing to do with being a hero," Dawn-Marie said. "That's being a human being."

The Trans World Airlines Flight Center at JFK International Airport is one of the most famous terminals buildings in the world. With its instantly recognizable lines, the Eero Saarinen designed building has been a New York landmark since 1962.

However, with TWA's demise in 2001, the terminal has sat abandoned for the past decade and a half. Now, the iconic structure is getting a new lease on life as an airport hotel. MCR Development, the hotel investment firm behind the terminal's revival, plans to restore the build to its original state while adding a 505-room hotel.

"The passion for this incredible building and the outpouring of support for our plan to preserve Saarinen’s masterpiece and permanently reopen it to the public as a 500-room hotel has been astounding," MCR Development CEO Tyler Morse said in a statement.

The TWA Hotel project has the support of New York Governor Andrew Cuomo.

"The conversion of the TWA Flight Center into a new state-of-the-art hotel will preserve this iconic landmark while cementing JFK’s status as a crown jewel of aviation," The Governor said during the hotel's groundbreaking last year.

According to MCR, the project is privately funded with no government subsidies.

The hotel is slated to open in 2019. Here's a closer look at the building, and some renderings of what it'll look like once the hotel is built:

• Esther Perel is a couples therapist and the author of "Mating in Captivity" and "The State of Affairs."
• She says showing empathy and taking responsibility are the "saving grace" of any strained relationship.
• You want to see your relationship as a "both/and" experience, as opposed to an "either/or" one.

Fights with a partner tend to escalate in a way that fights with, say, a coworker don't necessarily.

"I'm exhausted," one person might say. "I worked all day." "You're exhausted?" the other person might respond. "I worked all day and then went to pick up two screaming kids!" And so on.

Esther Perel has spent years watching this kind of dialogue unfold. She's a couples therapist and the author of the bestselling "Mating in Captivity" and the forthcoming "The State of Affairs."

Perel has found two behaviors that can stop a conflict like this one from spiraling out of control — behaviors that are so powerful she calls them the "saving grace" of any rocky relationship: showing empathy and taking responsibility.

When she visited the Business Insider office in September, Perel said, "There are not many things that are as important in a strained relationship as the ability to show empathy for the experience of the other; to acknowledge what the other person is going through; to validate that the other person is going through this, that it makes sense that they would be feeling this way."

Unfortunately, this doesn't happen often enough. Here's an example.

Perel recently came out with an audio series, titled "Where Should We Begin?" in which listeners follow along as Perel counsels a struggling couple. In the first episode, a husband and wife are dealing with the discovery of the husband's infidelity.

At one point, the wife says that after her husband betrayed her, she asked herself, "What was all that hard work for?"

The husband responds quickly: "I mean, I understand how you feel because I felt the same way."

Perel interjects here and tells the husband to avoid the impulse to "equalize" his experience and his wife's. Instead, she advises him to "reflect back" using the words, "So what I'm hearing you say is…"

Recent research supports the idea that empathy and understanding are key to navigating conflict successfully in a relationship. In one study, people who talked about a time when they'd clashed with their partner but felt understood were more satisfied with their relationships than people who talked about a time when they clashed but didn't feel understood.

In fact, one of the study authors told Quartz that simply telling the other person that you understand where they're coming from — even if you don't yet — may be helpful. (Perel tweeted about the research.)

The other component of keeping a struggling relationship afloat is taking responsibility for your behavior. Instead of evaluating the other person and scrutinizing their every misstep, Perel suggested flipping the mirror onto yourself.

"It's so easy to focus on what's missing in the other person. It's so easy to go critical. It's so easy to think that if you were different, my life would be better, rather than sometimes to switch it around and think if I was different, my life would be better. And maybe if I was different with you, you would be different with me."

It can be hard — our natural impulse in a conflict is to grab for the other person's shortcomings.

But Perel said you might ask yourself, "What is it that I do that may contribute to what you do?" For example, "Do I talk all the time and then I complain you never talk because I never give you any airspace?"

The point here is to see the relationship as what Perel calls "both/and," as opposed to either/or. "Every one of these situations, the degree to which we see it as complementary or the degree to which we actually focus on the polarization," she said, "that will make a huge difference on the quality of the relationship."

NOW WATCH: Here's why this wine costs $16,000 per bottle

For many of us, saving money is something we’d rather put off until ... any other time but now.

In some cases, it can even feel like an act of self-denial. If we have the money to buy an iced latte on the way to work, why save it for some point in the future when we can make ourselves happy right now?

Fortunately, saving money doesn’t have to be this way. Rather than thinking about spending less, it’s more useful to think about spending smarter. By seeking out deals and taking advantage of some basic personal-finance tools, you can start building your savings fairly quickly — without significantly limiting your lifestyle.

And by doing so, you’ll give yourself the freedom and flexibility to acquire the things you really want — a nicer home, a better computer, or a dream vacation.

Here’s a process you can use to start saving today.

1. Track your spending

It may seem like a hassle at first, but tracking your expenses is the only way to gain a clear understanding of where your money is going. This practice will help you identify where your spending isn’t adding much to your quality of life, and it will make you think more carefully about the purchases you don’t need.

There are several ways to do this. Free online software programs such as Mint will plug into your bank accounts to automatically give you a breakdown of your credit-card and debit-card transactions, with expenses filed under categories such as “restaurants,” “rent,” “travel,” and “entertainment.” But you’ll have to manually fill in the blanks any time you buy things with cash. If you want to be more precise, you can simply write down everything you buy, and then transfer your list to a spreadsheet that categorizes your expenses however you like.

2. Set your goals

Next, you’ll need to create a savings game plan. Start by deciding what it is you’re saving for, how much money it’s going to cost, and when you’ll need that money by.

For example, you may want to book a vacation a year from now that will cost $3,000. This means you’ll need to save about $250 a month. If you’re confident in your ability to hit your savings goal while still covering your bills and necessities, you can use an automatic transfer to put a certain amount of money in your savings account every month.

3. Look for easy savings

Now that you know how much you’re spending and how much you need to save, it’s time to start finding places you can spend your money more effectively.

A good place to start is your fixed monthly costs. If you save money on one of your bills, you’ll receive those savings every single month. For example, it’s always worth trying to renegotiate your cable bill. If you look up the lowest rates that your cable provider is offering to new subscribers, you can usually get them to lower your monthly payment to a number at or near what new customers are getting.

Another idea is to look for cellphone providers that don’t require you to sign a monthly contract, such as NET10 Wireless. This will give you the freedom to choose whichever plan makes the most sense for you in the upcoming month, allowing you to stop wasting money on data and minutes you’re never going to use.

By following these steps, you’ll be well on your way to saving the money you need to enjoy the products and experiences that make life worth living.

Remember, you don’t need to stop spending money; you just need to do it more intelligently

Aging can seem like a scary prospect, but a wealth of scientific studies have found that youth isn't all it's cracked up to be. There are plenty of cases in which human beings peak well into middle and old age.

Teenagers may have vitality on their side, but older people are generally more psychologically stable. And so it goes with several phenomena people experience as they age.

Many of the points mark the middle of an age range that scientists have identified, which means they are all determined by averages. Some are also surveys, not controlled trials, so there is a possibility the self-reports don't capture the most accurate picture.

But in many cases, the numbers keep cropping up for a reason, which is that life isn't a downhill slide from youth.

Here's what you have to look forward to.

Learning a second language is easiest when you're about 7 or 8.

Linguists and psychologists are still arguing about this one, but it's commonly accepted that learning a second language is easier for most people when they're younger, generally before puberty.

Brain processing power peaks at 18.

One of the key ways cognitive scientists test your brain's processing power is through what's called a digit symbol coding test — they equate a number with a certain symbol, then give you a string of numbers and ask you to convert them to the correct symbols.

On average, 18-year-olds fare best on the task, according to a study published in 2016.

The ability to remember unfamiliar names peaks at about 22.

We've all been there: You just met someone new, and their name went in one ear and out the other. It turns out that's least likely to happen when you're 22 or so, according to a 2010 study.

To maintain order in the classroom — and to keep their jobs — there are some things teachers just can't tell their students, even if they want to.

But some of these things, while perhaps controversial, could end up being a service to young people, if only someone would just tell them.

'Really, all this stuff you learn is probably not that important'

"What is important is the life skills you learn while completing the tasks in class.

"You learn how to argue effectively and communicate with different types of people. You learn how to listen to others and respond respectfully. You learn so much that you don't even realize because it seems disguised by homework and essays. But really, you are learning to be independent adults more than you know."

'Don't waste this opportunity'

"Please just know that I love teaching and I sincerely want to help you. But I can't help you if you don't put in the effort. I chose this job because I'm passionate and hardworking and I know my s---, and I will help you get to where you need to be. But you need to meet me halfway.

"It's so frustrating because education opens so many doors, and people around the world would kill to have this educational opportunity. Malala was shot in the freaking head for it. And you're just throwing it all away, and that makes me want to tear my hair out."

Lots of people working in Silicon Valley can't afford to buy a home there.

As a housing shortage in the San Francisco Bay Area continues to drive prices sky-high, some homebuyers are turning their attention to a micro-neighborhood — called Serra — located between the headquarters of Google and Apple. It's also known by its main drag, The Dalles.

This southwest corner of the town of Sunnyvale offers relatively affordable houses, proximity to major tech companies, and a small-town suburban feel. Still, Serra has flown under the radar, in part because few people know it exists. Google Maps doesn't even recognize the name.

Earlier this year, real-estate site Redfin named Serra the third hottest neighborhood of 2017. The site based the ranking on increases in internet traffic to listings in specific neighborhoods. Serra homes typically sell in under two weeks at 106% of the listing price.

Here's what life is like in the neighborhood.

I had my doubts about Serra, also known as "The Dalles," according to Redfin, before setting out for the more desirable neighborhood in Sunnyvale. Did it really exist?

not totally sure about the first line in the slide hed..are you saying there is a more desirable neighborhood than Serra? Based on my preliminary Google searches, Serra looked like a realtor's attempt to rebrand an existing neighborhood with a pleasant-sounding moniker in order to lure prospective buyers — likeNew York's made-up SoHa. None of my colleagues in San Francisco had ever heard of it.

Google Maps confirmed my suspicion. Searches for Serra and The Dalles turned up only Serra Park, the neighborhood park, and The Dalles, the street that bisects the area.

A map on Redfin provided some clarity. Serra spans about two square miles.

Fall may have just arrived, but it's already time to start planning for the winter holidays.

If you want to save money on airfare, that is.

Flights can cost up to 75% more at the end of the year than during non-holiday times, so booking travel before winter arrives can save you hundreds of dollars.

Because the week of Christmas is the busiest travel time of the year, you may want to prioritize booking those flights before you book your Thanksgiving trip.

The first week of October, or about 83 days before your departure date, is when you'll find the lowest prices for Christmas flights, according to travel app Hopper's Holiday Travel Index.

Hopper offers useful flight price reports, which track and analyze airfare to various destinations to help you figure out "when to fly and buy" for the lowest cost.

A typical domestic round-trip flight in December was priced at $366 in the last week of September, Hopper found, and prices will steadily rise from there.

If you're flexible with dates of travel, you'll save even more money.

According to Hopper, departing Saturday, December 16 or Tuesday, December 19, instead of the busiest day, Friday December 22, could save you around $110. And you can save $97 if you return home on January 4th, rather than New Year's Day.

A domestic round-trip flight for the week of Thanksgiving was $325 in the last week of September. Prices won't vary much in the next few weeks, but you could be paying up to $10 more per day if you wait to book until after Halloween.

The most expensive day to depart for the Thanksgiving holiday is Wednesday, November 22. You can save $54 by if you leave Thanksgiving morning or $48 if you leave earlier in the week on Monday, November 20th. You can save $161 by waiting until Wednesday, November 29th, to return instead of Sunday, November 26th.

Happy booking.

NOW WATCH: Marriott's CEO travels 200 days a year — these are his favorite travel hacks

Kevin Abosch, a visual artist who has photographed hundreds of people who work in the tech world, has just unveiled his latest series, and it highlights the highest-ranking women in tech. 

From Facebook's Sheryl Sandberg to Apple's Angela Ahrendts, powerful women from 25 different countries are featured in Abosch's series. He came up with the idea after he saw data from CoderDojo, a company that teaches children how to code. 

"[I was] looking at the data and you had all these kids — it was 50/50 boys and girls — until age 11. And then, 99% of the girls drop off. It was so freaky, it was shocking," he told Business Insider. "I never looked at my portraits of women in technology the same way after that."

The underrepresentation of women in tech is an issue that many companies — including Uber, Facebook, Apple, and Google — have tried to address in recent years. 

Below, see 10 portraits from the series.

"You can't be what you can't see," Sheryl Sandberg, COO of Facebook, said in a statement about Absoch's show. "This exhibit is important for girls and young women so they know Computer Science and STEM is for them. It's exciting to be a part of this effort to share images that will hopefully inspire others to get involved in our industry and bring more gender equality to tech."

Not all of the women included in the series work at tech companies. Joanna Coles, for example, is the chief content officer at Hearst. "A lot of people are behind the scenes of tech. Coles from Hearst, her job is using technology now to drive their business. Everything is digital now, and she's in charge of that," Abosch said.

From the 7th to 11th centuries, Anglo-Saxons moved into Londinium. Their settlement was laid out in a grid pattern and grew to contain between 10,000 and 12,000 people.

Last Thursday, Stephen Paddock checked into a $500 suite at the Mandalay Bay Resort and Casino in Las Vegas.

Now, the Mandalay Bay hotel is irrevocably linked to the deadliest mass shooting in modern US history, after Paddock opened fire on a crowd of 22,000 people at a music festival across the street from the 32nd-floor window of his hotel room.

He killed 58 people and wounded nearly 500, police say.

Often, sites of tragedies become an area of mourning and remembrance. However, the room where Paddock executed his killing spree is unlikely to become that.

"From my opinion, the room disappears," Anthony Melchiorri, the host of Travel Channel's "Hotel Impossible," told Business Insider.

Melchiorri said that if he were running the hotel, he would reach out to victims and their families to see how he could best help them.

Then the room in question — which has been identified as Room 135 on the 32nd floor— would most likely no longer be available for guests to book. Melchiorri said he would go so far as to have the doors sealed up, removing any trace of the suite's existence.

Deanna Ting, the hospitality editor at the travel-industry intelligence company Skift, agreed that the room would probably not be available to be booked — at least not for a very long time.

Beyond the room in question, both Ting and Melchiorri emphasized the importance of the Mandalay Bay reestablishing the hotel as a safe and secure space for guests.

Housekeeping staff members and other employees could be retrained on how to respond if they see something suspicious. Ting predicted that a visible security presence— such as metal detectors, X-ray machines, or armed guards — would flood Las Vegas hotels, at least in the short term.

Las Vegas hotels already have some of the best security in the country — Melchiorri said the city had "more security per square foot" than any other city in the US.

Debra DeShong, a representative for the Mandalay Bay's parent company, MGM Resorts, told Business Insider in a statement that the company "works consistently with local and national law enforcement agencies to keep procedures at our resorts up to date" and was "always improving and evolving."

However, for the Mandalay Bay and other hotels in Las Vegas to convince guests of their safety, drastic and visible changes are likely to be necessary.

Ask just about any educator and they'll tell you: There are many joys that come with teaching.

From witnessing students finally understand something they were struggling with, to seeing how unique every child is, teachers get to share in some pretty special moments.

Dig a little deeper, and these teachers will also tell you that not all "special moments" are conventional — inevitably, there are some oddities that come with molding the future generation.

We asked teachers everywhere to share some of the stranger things they've experienced on the job, and, well, we were overwhelmed by all the weirdness. As one teacher said, "Every day something weird happens. Your students will say and do the weirdest things, and you will laugh every day."

Here are some of the most interesting (and anonymous) things teachers said they've encountered.

The darndest things

"A student (and then later a teacher) suggested that I hurt the teacher I had been replacing so that I could stay."

"Students notice absolutely everything. I had a student once who remembered every bag I own (like 10 of them) and most of my outfits. At the end of the year she told me all of her favorite one of my looks."

"I was once asked what my real job was."

"I had a student who would call me 'mom.' He lived with his mother and loved her dearly, but when he got to school he would call me 'mom' as well."

Fellow teachers and administration acting up

"There are some teachers who are mean and don't enjoy children but somehow still teach and have a job."

"My first year of teaching showed me how much a crazy, incompetent administration can ruin a school. After a new principal came in, every teacher left, except for three who remained — three teachers out of dozens for an entire high school! The principal had three different investigations running against her for harassment, forging documents, and physically abusing students, and nothing happened to her! Crazy."

"Another teacher stole from me."

"I've seen administration, who get paid tens of thousands more than the highest paid teachers, acting inappropriately and unprofessionally — and then those are the people who evaluate us."

Love, sex, and loneliness

"There have been multiple marriages from within my department."

"I once saw performance art depicting the phallic symbolism of 'Moby-Dick.'"

"I found a sex toy in a two-year-old's backpack. Holy awkward phone conversation!"

"A student brought me in a list of dating websites for Valentine's Day."

"I have dealt with weird issues with kids I never thought I would, like the time a kid asked me to deliver a note to their friend that contained information about the friend's girlfriend cheating on them. You just never know when you work with teenagers."

Las Vegas hotels are increasing security measures after the deadliest shooting in modern US History was carried out from the Mandalay Bay Hotel and Casino. 

Mandalay Bay and other MGM Resorts, including the Bellagio, Monte Carlo, and the MGM Grand, have increased security levels, according to a spokesperson from the company. The Wynn Resort in Las Vegas added new security measures after the shooting, scanning guests with metal detectors and putting bags through X-ray machines. 

"The very first thing that hotels [will consider] is more visible security," Deanna Ting, hospitality editor at travel industry intelligence company Skift, told Business Insider. "The hotels in Las Vegas are going to start asking themselves if they should have metal detectors or baggage screenings at the entrance of their properties." 

There are no industry-wide security standards in the hotel industry. Before now, most Las Vegas hotels have not had metal detectors.

And, according to experts, there's a good reason for that.

Las Vegas hotels are packed with hundreds to thousands of people. Mandalay Bay has 4,700 rooms. The Venetian, which is the city's largest hotel, has more than 7,000 rooms. Getting people checked in, into elevators, and up to their rooms smoothly is a difficult enough feat. Adding metal detectors or other screening measures would create inevitable bottlenecks.

"Imagine yourself going to Las Vegas for a conference," Dick Hudak, managing partner of the Resort Security consulting firm, told Business Insider. "Are you going to be very happy after traveling five or six hours through airports, and then you get to the hotel and you're standing in line, and you have to pick up your suitcase and put it on this conveyor belt?" 

"Is it reasonable to screen them?" Anthony Melchiorri, host of Travel Channel's "Hotel Impossible," asked rhetorically. "I don't think so." 

Ding believes hotels will likely consider visible security when guests check in, especially in the short term to boost customers' confidence. But, she says hotels would have to deal with questions of privacy and the cost of installing and maintaining machines if they want to use them for screening in the long term. 

Some hotels internationally have successfully added X-ray machines or metal detectors after catastrophic incidents. Certain hotels in Indonesia, for example, added X-ray machines after a bombing in 2003 at a Marriott Hotel in South Jakarta.

However, while Americans are willing to sacrifice convenience for safety in airports, they may be less likely to do so in hotels. 

"Security requires inconvenience. Certain industries can deal with inconvenience, like banks, airlines," said Hudak, who previously worked as director of security at Sheraton. "Hotels can't deal with inconvenience. Guest will go someplace else where they don't have to deal with this stuff." 

In other words, Americans value convenience — and if a hotel can't offer that, guests will go to another hotel or Airbnb that can.

NOW WATCH: 'It was an act of pure evil': Watch Trump's statement about the Las Vegas shooting — the deadliest shooting in modern US history

For food startup Hampton Creek, the egg is ground zero.

The San Francisco-based company's mission is to transform the way we eat by replacing the animal products in our food with ingredients that can be made from plants.

It all began with a product called "Beyond Eggs," a pea-based egg-replacement that can be used for baking but not eaten alone. Hampton Creek CEO Josh Tetrick, a long-time vegan, portrayed the product as the first of a long line of products that would eventually turn our food system — which he calls "completely broken" — upside down.

"We're trying to take the animal totally out of the equation," Tetrick told NPR in 2013.

Tetrick is right that our food system isn't sustainable — producing a half-pound of beef results in roughly 7 and a half pounds of carbon dioxide emissions, or the equivalent of driving nearly 10 miles. Producing the same amount of potatoes, on the other hand, requires about a tenth of that CO2. Decreasing the amount of meat Americans consume could make a big difference for the planet.

Hampton Creek's message has resonated with consumers. Six years after the company was founded, it has raised more than $220 million and currently is valued at $1.1 billion. Since debuting the pea protein-based "Beyond Eggs" in 2013, the company has released a line-up of plant-based alternatives to foods that rely on animal products, including cookies, dressings, and a popular eggless mayonnaise that's sold in stores like Wal-Mart and Whole Foods. 

In 2015, Hampton Creek was named a "Technology Pioneer" by the World Economic Forum; that same year, its revenues grew 350%. Its products are now served in more than 3,000 K-12 schools and 500 universities as well as in stadiums, corporate cafeterias, and government agencies.

But Hampton Creek still hasn't cracked the eggless egg — at least not one that can be cooked and eaten on its own.

Peas — in the form of pea protein isolate — are the centerpiece of "Just Mayo", while the company's "Just Cookies and "Just Dough" feature sorghum. But neither of those ingredients have yielded a stand-alone egg substitute. Various test versions of an eggless scrambled egg product, which Tetrick said might eventually be called "Just Scramble," have repeatedly failed to hit the mark. Alice Park, a science writer for TIME, wrote in 2014 that one version of the scramble tasted more like tofu than eggs.

But Hampton Creek has kept at it. Their latest version of the scramble (which is not yet on the market) is made with mung beans; Tetrick and other staff members have taken to simply calling it "Jack" or "the magic bean."

On a recent tour of the company's headquarters, we gave it a taste. Ben Roche, one of the company's heads of product development and a Michelin-starred chef, poured some of the yellowish liquid into a frying pan. 

After a few minutes, the scramble began to look, well, like scramble. Along the bottom of the pan, a soft layer of what looked like perfectly-beaten eggs began to solidify, and as Roche stirred, the mixture started to take on a more defined shape. Again, it all looked like typical egg behavior.

Roche scooped the finished product into a small bowl for me and sprinkled it with a bit of sea salt. The product certainly looked like eggs — it had the texture and the characteristic pastel-yellow color, and it was steaming like a hot plate of scrambled eggs normally would.

I shoved a forkful of the scramble into my mouth. It didn't taste like eggs. But it wasn't bad, either.

Next, Joshua Hyman, Hampton Creek's head of culinary programs, introduced me to the company's latest iteration of the eggless egg: patties. These don't have an official name yet, but Hyman told me envisions them being sold in schools and universities much like their egg replacement product.

Hyman slid what looked like an egg sandwich towards me — the egg patty (which is the same as the scramble, but formed into a patty shape) was inside a toasted bialy smeared with a light dusting of "Just Mayo".

I tried a small bite of the sandwich — which had preemptively been cut into quarters as though in acknowledgement of my skepticism — and was blown away. The texture was perfect and the taste was distinctly egg. It didn't seem like it could be the same product, but perhaps all the "Just Scramble" needed was a bit of crispiness and a smidge of creamy pea protein. As we talked, I ate three more pieces. Running out of time, I put the fourth in a bag to take home.

Hyman told me that he envisions the patties being sold as an alternative to the scrambled eggs that normally go in foods like egg sandwiches and breakfast burritos.

In addition to the scramble and patties, the company is testing out a healthier version of their original mayo product and an ice cream and butter made with mung bean as the base ingredient. Tetrick also told me they're "close" to producing lab-grown meat, something the company first unveiled they were working on in June. The product will be in the avian family, according to Tetrick, but our guess is that it will be chicken.

"Right now if a really great burger was a 10 and a McDonald's burger was a 6, this is a 4. We're not there yet," he said.
