Mathematics is full of counterintuitive facts and problems that push your mind to new areas and challenge your cognitive versatility. 

The next nine facts are just a few of those puzzles; problems that have a habit of sparking arguments and debates among even some of the smartest students. 

While they may seem controversial, they're all rock solid fact. 

Several of them are paradoxes and idiosyncrasies of probability.  Others play your instincts against your logic. If you're looking for a mathematical way to impress your friends and beguile your enemies, here's a good place to start. 

Just a heads-up, these problems are a little tougher than last time. If you lose track, don't quit.

Gentlemen, let loose your inner samurai when you stay in these latest “wa-kapu” Japan-themedcapsule rooms at the Business Inn New City in Yokohama City.

The five-floor Business Inn New City located in Yokohama City, Kanagawa Prefecture, began taking reservations for its newest set of themed capsule rooms this past Monday. These rooms mark the second time that the hotel has offered specially decorated concept rooms; the previous “痛カプ” anime-themed rooms have already proven to be a big hit with Japanese people and foreigners alike.

As long as you don’t mind the relatively cramped quarters and communal bathroom areas, capsule hotels are typically a great deal for anyone looking for an inexpensive place to crash while traveling or after missing the last train (it’s important to note that while the majority of capsule hotels cater to men, there are a few options for the ladies out there). However, these particular Japan-themed capsule rooms at the Business Inn New City are alluring enough that we can picture many men booking a room just for the fun of it all!

As per the theme, the floor of the communal space in the new capsule room area is covered with tatami mats, and images of Japanese castles and samurai armor line the capsule walls along with ukiyo-e style artwork. 

Even the curtains for the individual capsule rooms are embellished with the family crests of prominent warriors from Japan’s feudal era.

Spend your time reading one of 25,000 volumes of manga, watching one of 400 films, browsing the internet, or lounging in the TV chairs available in the hotel’s relaxation areas!

Enjoy a pleasant soak in the communal public bath…

As our wild holiday party stories prove — no matter how much warning they're given, some people just can't help but let loose during the company holiday party.

And this is a real concern for employers.

Of the almost 400 human resources professionals who plan to sponsor an end-of-year or holiday party surveyed by the Society of Human Resources Management (SHRM) this November, 41% said they don't plan on serving alcohol at all. This is up from 39% in 2012.

Of those who do plan on offering libations, almost half (47%) said they would regulate alcohol consumption at the party in some way.

"Holiday or end-of-year parties are great opportunities for employers to team build, acknowledge individual and company achievements, and boost employee morale," Sherry Dixon, senior vice president with Adecco Staffing USA, tells Business Insider. "While it's important to give employees the opportunity to let loose a little, it's also critical to keep things professional."

Keeping things professional is a major concern for employers because of liability issues, says Roy Cohen, a career coach and author of "The Wall Street Professional's Survival Guide."

"When problems occur at holiday parties, there is real potential for the company and corporate brand to be tarnished," he tells Business Insider. "That opportunity cost is significant. Many more companies are aware of the impact on reputation and the power of the internet to broadcast bad behavior immediately and for eternity." 

While employers obviously have no way to control what goes on at the holiday after-party, here are nine ways they can keep people from drinking too much on the company's watch:

DON'T MISS: The 27 jobs that are most damaging to your health

1. Provide drink tickets

Most (71%) of the employers offering alcohol at a year-end or holiday party surveyed said they planned to keep people from drinking too much by providing drink tickets or a drink maximum. 

"Not only does this help keep everyone safe, it also could be helpful in preventing employees from saying or doing discriminatory or offensive things while under the influence," says Gretchen Van Vlymen, human resources practice leader at StratEx, a human resources service and software company.

2. Set expectations of good behavior up front.

Van Vlymen says there tends to be an uptick in sexual harassment complaints following holiday parties where heavy drinking is involved, which is why her company advises clients to remind employees beforehand that the handbook policies on harassment still stand and drunkenness isn't a valid defense for such behavior.

"To encourage professionalism at your office party, it is okay to set expectations beforehand," Dixon says. "In a kind and non-threatening manner, ask employees to limit alcohol consumption at the celebration, reminding them that inappropriate behaviors take away from team bonding."

Meredith Hurst, a partner at Thomas Mansfield, an employment law consulting firm, says a gentle reminder usually does the trick without putting the dampeners on the party. "In the vast majority of cases, trusting staff to act in the right way can reap its own rewards," she tells Business Insider.

Another tack Van Vlyme says some employers take, though, is to ask employees to sign an acknowledgment of the handbook policies on harassment and discrimination prior to the start of the party. 

3. Don't offer hard liquor.

A quarter of the human resources professionals surveyed reported they would only serve certain types of alcohol, like beer or wine.

"There is a major upside in preventing employees from being overserved by prohibiting shots at the open bar," Van Vlymen says.

Wall Street analysts and economists speak their own language. 

Words like "research" and "analysis" mean one thing to regular folks, but something totally different to the folks with a financial interest in how they are perceived.

To address this, Wall Street Journal columnist Jason Zweig is out with a new book, "The Devil's Financial Dictionary," which features satirical, yet insightful definitions that decode the meaning of everyday financial jargon.

Just in time for the holidays, this compendium of Zweig's wit is the perfect stocking stuffer for anyone remotely interested in finance.

We picked 13 terms from 200+ page text and shared them below.

The median household income in the US is $53,657. If your salary exceeds $75,000 a decade after starting college, then you're doing pretty well for yourself.

A handful of US colleges have prepared their graduates to do just that, according to a recent report from the Georgetown University Center on Education and the Workforce. The report used the US Department of Education's College Scorecard to highlight the median earnings of students from over 1,400 colleges 10 years after starting their studies.

Here, we've gathered the 17 colleges where graduates are earning over $75,000 a year:

Women think men are difficult to shop for, and men think women are difficult to shop for — that's just the way the world spins.

If the woman (or man) you're shopping for is someone you'd deem fashionable, though, we feel for you. That can be a whole different level of intimidating. You don't want to get her something she hates, but knowing what's "in" this season isn't necessarily your area of expertise either — in all likelihood, it's hers.

So to help guide your gifting, we compiled 18 presents — ranging from mirrored sunglasses to lace-up ballerina flats, from faux fur outerwear to edgy diamond studs — we think she'll love.

Every woman's sartorial predilections are different, of course, but this list is a good place to gather some ideas.

A cropped sweater

Sweaters make great gifts. For the forward dresser, pick out a cropped one: Abbreviated hems continue to be a popular style, even as we head into winter. The subtly slouchy collar of this turtleneck will lend some extra coziness on cold days.

Club Monaco Leala Crop Turtleneck, $149.50.

A pair of headphones

There's no shortage of stylish headphones you can buy. Twist our wrists, though, and we'd pick Frend's Layla Headphones (pictured here), Master & Dynamic's MH40s, and Bang & Olufsen's BeoPlay H6s as our favorites for any women you're shopping for this season.

Frends Layla Headphones, $149.99.

A pair of mirrored sunglasses

Pair these mirrored sunglasses with a surprise tropical getaway and win Christmas.

Getting back to nature can be like going back in time, especially if you wander through one of these woodlands—all amongst the oldest on Earth.

Some are old growth, meaning they haven’t been molested much by people, while others are forests that have been regenerating on the same land for time periods that make centuries look like seconds.

And a few, like the Bristlecone Pine Forest in California, are made up of some of the oldest existing living life forms.

Lace up your hiking boots, grab your pack, and prepare to enter some of the most ancient places on our planet. 

The Tarkine, Australia

You can pull freshwater crayfish the size of lobsters out of the rivers in Tasmania's Tarkine forest. That's no exaggeration—the island's isolated Tarkine woodland is a glimpse back to life on Earth 300 million years ago.

It is the second largest swatch of temperate rainforest in the world and home to 3,000-year-old Huon Pines, the second oldest living trees in the world.

Visit today because less than five percent of the trees are protected and the forest is threatened by mining and logging. It's breathtakingly beautiful—a blanket of myrtle, blackwood, sassafras, and eucalyptus trees covering, ferny hills, waterfalls and gullies. Bunk at Bonorong's Tarkine Trails' Tiger Ridge, a hike-in only glamping getaway, little more than half-a-mile into the wilderness.

They lead day hikes through the most beautiful parts of the forest, and you're almost assured to see signs of the Tasmanian Devil—they work with the Tassie government to monitor these elusive and endangered critters.

Otherwise, there are a cluster of rustic towns surrounding the woods to call home—no matter which you pick, spend some time asking about the local Tarkine aboriginals, whose culture, like the forest, is in danger of disappearing.

The Aracuaria Forest, Chile

The Aracuraria tree, a Chilean pine which can live to be 1000 years old, is thought to have evolved its peculiar upside-down paintbrush shape to ward off plant-eating dinosaurs 180 million years ago.

Chile's since given these Jurassic-era beanstalks National Monument status. The forest is most gorgeous in central Chile's Conguillio National Park and Tolhuacaca National Park, with some astounding mountain backdrops. But you'll also see these trees if you do the Villaricca Volcano summit, the most popular day hike in the area.

You can book beforehand with Amity Tours orSummit Chile, but if you know some Spanish you can also pick up a guide in Pucón.

Head there between November and December and you'll catch the coning season, which yields pineapple-shaped conifers that produce seeds the indigenous Penuenche use in local dishes. 

Yakushima Forest, Japan

The moss-covered stones and nappy roots of Yakusugi trees—Japanese Cedar—have been steeping in these constantly wet woods for around 7,000 years.

This small island's foliage was so beautiful to 17th Century Edo-era royalty, they cultivated lush gardens of it on the mainland. But the wide-trunked trees grow naturally all over Yakushima. Seeing this UNESCO World Heritage site is fairly straight forward—land at Yakushima Airport and either rent a car or take the bus that circumnavigates the mountainous island.

There are hotels along the northern and southern coasts. Shiratani-Unsuiky Park has the most easily accessed iconic spots, including the vision that inspired the backdrop of eco-animé classic Princess Mononoke.

If you hike the extended trails in the park, you can sleep in one of six semi-permanent shelters set up for campers. Look for the Takatsuka Hut, designed out of cardboard tubes by famed green-architect Shingeru Ban. May and October are the driest times to go, but you should still pack for the rain. 

From a car outfitted with its own pizza oven to one made almost entirely out of cardboard, 2015 was a weird year for vehicular designs.

Not all the vehicles below are available for purchase (though some, unbelievably, are), but they highlight how experts are innovating with unique designs and new materials. 

These are the 16 most bizarre vehicles we've seen this year!

16. This foldable electric scooter — the URB-E — will let you ride for 20 miles on a single charge.

15. The Gi FlyBike electric bike can fold in half in just one second.

This week, I embraced my cavewoman roots and ate a Japanese sea urchin from my hand.

My experience was a teaser for a dinner series put on by Brooklyn Brewery that explores the relationship between food and sense of touch.

"It's meant to make you think about how your experience of the food changes when you concentrate on one of the senses," says Andrew Gerson, Brooklyn Brewery's chef and head of culinary programming.

Here's what happened when Gerson prepared the edible urchin in my palm at Food + Tech Connect's "Future of Food Bash."

Food + Tech Connect held the bash in a Brooklyn warehouse. Foodies and booths featuring futuristic food start-ups filled the space.

Although a little hesitant to try sea urchin, I approached Brooklyn Brewery's booth.

After Chef Gerson sprayed my hand with a water and lemon-based cleaning solution, he squirted on a dab of squash pureé. It was a mix of onion, cultured butter, ginger, hoisin sauce, and butternut squash, he said.

Krispy Kreme doesn’t want to be Starbucks. However, the chain is drawing inspiration from coffee shops as it looks to the future.

In October, the donut chain opened a new location in Clemmons, North Carolina with some serious coffee shop vibes, including vintage signs, natural wood, free WiFi, and a redesigned ordering system and seating area.

The concept store represents a major step forward in Krispy Kreme’s plan to increase coffee sales, which currently make up 5% of sales — a figure that CEO Tony Thompson told Business Insider he believes the company could double.

“We love to hear, ‘We used to go to Starbucks, but this is pretty cool too,’” says Thompson on customers, especially younger ones, he meets at the Clemmons concept shop. “[Krispy Kreme is] not trying to go be a Starbucks. What we want out of this is, people are coming for the donut. We want to attach [coffee].”

Here’s how the new shop is trying to do just that — and what it means for the future of the brand.

The aspect of the new location most likely to show up at your local Krispy Kreme is the coffee-centric ordering system.

When customers come to a Krispy Kreme, they are drawn straight to the donut case, like moths to a flame. 

However, the traditional ordering system — order donut at the case, then go pay at the register — often reduces the chance of customers getting a beverage to go with their sweet treats. So, with the new location, ordering coffee and donut is finally linked. 

"We know people are coming to the case. So, let’s up the POS there, let’s start where they go," says Thompson. "Don’t push them to do something different — you know where they’re going to go."

Krispy Kreme is already working on retrofitting the new ordering system at some existing locations, as well as select new shops.

The company isn't ready to share the exact figures, and it's not replicating the entire store, but different locations are expected to take on aspects of the Clemmons ordering system. 

In some areas, the company will add a barista and a manual espresso machine. In others, it will be a matter of rearranging the donut case and point of sales system to fit the new customer flow design. 

Continuing the coffee shop vibe, the seating area has been reworked to be more modern and inviting.

The location has soft seats and high-backed chairs, free WiFi, and more plugs along the wall for customers looking for somewhere to plug in their laptops and sit for a while. 

"To really address coffee, you’ve got to do more than just have a new menu item, or just some new news," says Thompson. "You need to have the overall experience be about coffee.”

Down the road, some aspects of this new experience may become the norm at Krispy Kreme locations, as the company continues to collect data at the Clemmons shop. 

Golf is one of the most popular sports in South Korea.

But most of the golf courses are far from the city, and a lot of them are pretty expensive.

So instead of going to an actual golf course, people like playing at a place called "screen golf" centers. It basically lets you play with a golf simulator, but it's much better than what you'd imagine.

I tried screen golf during a recent trip to Seoul — and it absolutely blew me away.

SEE ALSO: Riding the subway in Seoul showed me how far behind New York is

This is the lobby of the screen-golf center I went to. You can easily find screen-golf centers in Seoul, just like you’d see a Starbucks on every other corner in NYC.

It’s pretty affordable, too. You’d pay about $20 on average to play all 18 holes. Usually there’s no time limit.

This is what a typical screen-golf room looks like. The place I went to had 15 of these rooms.

One surefire way to find a great book to read is to see which ones top the best-seller charts.

Amazon recently released its list of the 20 best-selling books of 2015, and chances are, if you haven't already read a few of these yourself, you know someone who has.

It's not too late to read — or reread — the bestsellers of the year. Keep scrolling to see which books made the list.

20. "A Spool of Blue Thread" by Anne Tyler

"A Spool of Blue Thread" spans four generations of the Whitshank family — a loving group of people who share laughter, tender moments, milestones, and the challenges of growing up — but just like any other family, they also experience disappointments, heartache, jealousy, and deep-rooted secrets.

From Baltimore in the 1920s to the summer in 1959 when Abby Whitshank fell in love with Red, Pulitzer Prize-winning author Anne Tyler paints an intimate picture of a flawed, but close-knit, family.

18. "The Crossing" by Michael Connelly

Even though Harry Bosch retired from his detective job with the LAPD, the work isn't over: Bosch's half-brother is an attorney who believes his client has been framed for murder, and he need's Bosch's help now more than ever.

Bosch takes the case as a favor to his brother, but when the real killer discovers that Bosch is hot on his trail, a dangerous game of cat-and-mouse ensues.

Uber may be only five years old, but it sure knows how to throw a holiday party like the rest of the Silicon Valley giants. 

For Uber's bash, the ride-hailing company rented out the Pier 27 cruise terminal in San Francisco and transformed it into a silent disco party. There was an open bar, a doughnut station, and plenty of headphones passed around so employees could groove. 

Even Uber's CEO Travis Kalanick made an appearance with a special guest, who clearly won best in show. 

Here are some of the highlights from Uber's silent disco.

Our days are filled with a constant stream of decisions. Most are mundane, but some are so important that they can haunt you for the rest of your life.

A recent study from Columbia University found that we're bogged down by more than 70 decisions a day. The sheer number of decisions we have to make each day leads to a phenomenon called decision fatigue, whereby your brain actually tires like a muscle.

A new study from the University of Texas shows that even when our brains aren't tired, they can make it very difficult for us to make good decisions. When making a decision, instead of referencing the knowledge we've accumulated, our brains focus on specific, detailed memories.

For example, if you're buying a new car and trying to decide if you should go for the leather seats, even though you know you can't afford it, your brain might focus on memories of the wonderful smell and feel of the leather seats in your brother's sports car, when it should be focused on the misery you're going to experience when making your monthly car payments. Since you don't have memories of this yet, it's a hard thing for your brain to contemplate.

"I am not a product of my circumstances. I am a product of my decisions." — Stephen Covey

Some decisions are minor, such as what to eat, which route to drive to work, or in what order to tackle tasks; others are more difficult, such as choosing between two job offers, whether to move to a new city for someone you love, or whether to cut a toxic person out of your life. Regardless of the magnitude of the decision, our brains make it hard for us to keep the perspective we need to make good choices.

Bronnie Ware spent her career as a palliative care nurse, working exclusively with people who were three to 12 months from death. She made a habit of asking them about their greatest regrets, and she heard the same five regrets time and time again. By studying these regrets, you can make certain that you make good choices and don't fall victim to them yourself.

Here are five of the most common regrets:

SEE ALSO: People weighed in on the most common regrets in life, and some of their answers will make you cry

DON'T MISS: The 27 jobs that are most damaging to your health

1. Making decisions based on what other people think.

When you make your decisions based on other people’s opinions, two things tend to happen:

1. You make a poor career choice: There are too many people out there who studied for a degree they regret or even spent their lives pursuing a career they regret. Whether you’re seeking parental approval or pursuing pay and prestige over passion, making a poor career choice is a decision that will live with you forever.

2. You fail to uphold your morals: When you get too caught up in what your boss thinks of you, how much money you think your spouse needs to be happy, or how bad you will look if you fail, you are at high risk of violating your own morals. Your intense desire to make yourself look good compromises your ability to stay true to yourself and, ultimately, to feel good.

The best way to avoid falling prey to the opinions of others is to realize that other people’s opinions are just that — opinions. Regardless of how great or terrible they think you are, that’s only their opinion. Your true self-worth comes from within.

2. Working too hard.

Working hard is a great way to impact the world, to learn, to grow, to feel accomplished, and sometimes even to find happiness, but it becomes a problem when you do so at the expense of the people closest to you.

Ironically, we often work hard to make money for the people we care about without realizing that they value our company more than money. The key is to find a balance between doing what you love and being with the people you love. Otherwise you’ll look back one day and wish you’d focused more on the latter.

3. Failing to express your feelings.

We’re taught as children that emotions are dangerous and that they must be bottled up and controlled. This usually works at first, but boxing up your feelings causes them to grow until they erupt. The best thing you can do is to put your feelings directly on the table. Though it’s painful to initiate, it forces you to be honest and transparent.

For example, if you feel as though you don’t make enough money at work, schedule a meeting with your boss and propose why you think you’re worth more. As a result, she will either agree with you and give you a raise or disagree and tell you what you do need to do to become more valuable. On the other hand, if you do nothing and let your feelings fester, this will hinder your performance and prevent you from reaching your goal.

The "Star Wars" fandom knows no bounds. Even celebrities are obsessed with the galaxy far, far away. 

With the release of "Star Wars: The Force Awakens" this weekend, people around the world are celebrating the highly-anticipated return of beloved characters like Han Solo, Leia, and of course, the arrival of BB-8. 

From a bounty hunting pop star to cosplaying actors, here are 15 celebrities you didn't know were obsessed with "Star Wars."

Amy Schumer got up close and personal with C-3PO.

In a photo shoot with GQ earlier this year, Schumer posed in bed with "Star Wars" droids C-3PO and R2-D2. The shoot wasn't approved by Disney and definitely shocked many fans of the force. 

Kevin Smith said visiting the "Star Wars" set made him cry.

When "Star Wars: The Force Awakens" director invited Smith to visit the film's set in England, Smith took him up on the offer. 

Smith posted a teary-eyed Instagram picture and said being on set made him feel young again. 

"When I was a kid, I liked 'Star Wars,' and now I’m on the 'Star Wars' set,"the actor told the LA Times of the experience. "The moment I stepped on the Millennium Falcon 10 years dropped off my life."

Tina Fey shows her love for all things Leia.

When Tina Fey walked down the aisle as Liz Lemon in the last season of "30 Rock," it was dressed in Princess Leia's classic white robe and twin hairbuns. 

"It's the only white dress I own," Lemon quips. 

In real life, Fey was spotted wearing a "Vote Princess Leia" shirt on "Saturday Night Live" in 2008. 

Editorial note: Business Insider just named its 2015 Car of the Year, the Volvo XC90. This weekend, we're re-running our reviews of the five cars that almost beat out the Volvo for the honor.

Everybody's got the wrong idea about Lamborghinis, and that's kind of the way Lamborghini likes it. The cars are blazingly over the top, willfully inappropriate, and boldly nonconformist. They shout, they scream. They are not designed for people with modest self-esteem. They are the opposite of Volvos. Even for Ferrari owners, they're a bit much. But the new Huracán is going to definitively change that impression.

Named for a Spanish fighting bull, in the Lambo way, as well as a Mayan wind god and, of course, the Spanish word for "hurricane," the Huracán was introduced last year and replaces the Gallardo, the all-time best-seller for the carmaker, which was in production for a decade.

With a 5.2-liter V10 engine, midmounted, the Huracán continues the Gallardo's newish tradition of a "small" Lambo to accompany the big V12 Lambos that serve as the brand's flagship cars — at the moment, that would be the Aventador, but previous storied names included the Countach, Diablo, and Murciélago. Those cars are flat-out bonkers. You'd wave a red cape at them at your own considerable risk. The V10s are, well, more mannered, while certainly not tame.

And with the Huracán — despite its name — Lambo has put a little more distance between the big Lambos and the little Lambos. Some of this can be either attributed to or blamed on, depending on your attitudes toward what a Lambo should be, Lambo's position in the VW Group and its relationship with corporate stablemate Audi.

The Huracán and the R8 have a lot in common under the sheet metal and carbon fiber. The R8, despite the "Iron Man" associations, is regarded as an "everyday" supercar, and a healthy dose of the mundane has been injected into the Huracán. That is, until you make a few adjustments to the driving settings. Then you have all the Lambo you could ever want, as we found out when the automaker let us borrow a Huracán for a few days of rain and shine.

Lambos are usually spotted in completely outrageous colors. We were honestly looking forward to something shocking in our suburban New Jersey driveway, test central for Business Insider.

Maybe something a little like this Lamborghini Diablo, in flamboyant orange. Lock up the kids!

What we got, however, was a midengine beast elegantly tailored in soothing, dignified tones of gray. We photographed the Huracán from every imaginable angle, in rain and glorious autumnal shine ...

What happens to my 401(k) when I change jobs?

Great question this week! You have a few different options of what you can do with your 401(k) when you switch jobs.

1. You can leave it in your old employer's plan and do nothing.
2. You can roll over the money into your new 401(k) plan.
3. You can roll over the money into an IRA.
4. You can roll over the money into a Roth IRA and pay taxes on the conversion.
5. Cash out (make it rain!) and get hit with a 10% penalty, plus a boat-load of taxes. (Hint: Don't pick this one.)

A few things you should know: When you contribute to a 401(k), the employee contributions are kept separate from the employer contributions. Any money you contributed as the employee is 100% vested immediately (meaning it's yours to keep if/when you leave).

Sometimes employer contributions are 100% vested immediately and sometimes they have a "vesting schedule." Therefore, on your 401(k) it might show a "vested balance" which is the total amount you can move when you change jobs. This is to encourage employee retention.

Let's explore those five options further:

1. You can leave it in your old employer's plan and do nothing.

This happens a lot.

Action takes effort and as humans, we tend to be lazy. By leaving your account with your previous employer, you're limited to the investment options that are in the plan, and you can often find less costly and more robust investment options if you open an IRA or Roth IRA and do a rollover.

This isn't the worst thing you can do, but you should check the fees you're paying to keep your account there — start by checking the expense ratio of the funds in the plan on Morningstar.

If the fees are more than .5% on each fund, I would recommend doing a rollover.

2. You can roll over the money into your new 401(k) plan.

One place you can roll over the funds is into your new employer's 401(k) plan.

Check the expense ratios of the fund choices in the plan first before you do this. If they're higher than an average of .5%, then I would roll over the funds to an IRA or Roth IRA instead.

Some people prefer the simplicity of having all their 401(k) money in one place. If the balance is fairly small (less than $10,000), then the fees have a small impact on your decision and you might favor simplicity.

Again, you'll be limited by the fund choices in your new employer's plan, so look into them before you roll over a big balance. You won't pay any taxes on the rollover or pay penalties from moving one 401(k) to another.

3. You can roll over the money into an IRA.

The most common recommendation that I make for clients is to roll over their old 401(k) into a new IRA.

There are many discount brokerage firms where you can set up an IRA but here are a few of my favorites: Vanguard, Schwab, Fidelity, and Betterment. (I have a relationship with Betterment Institutional, so that's where I manage my clients' assets).

Vanguard is known for having some of the lowest expense ratios on index funds and ETFs, but you'll need at least $3,000 to open a new account there (plus their website is clunky). Schwab and Fidelity both have a list of commission-free ETFs that I like because you don't have to pay a trade fee every time you buy one. (Schwab's list here, Fidelity's here.)

Betterment is my cup of tea for novice investors that want to keep things simple: They don't have a minimum to invest, their website is extremely user friendly, they use a lot of low-cost Vanguard and Schwab ETFs but they can buy fractional shares, and it's super easy to automate contributions.

Again, there's no tax implication to roll over a 401(k) to an IRA Rollover and you won't pay any fees to do this. Here are the steps to do this:

1. You will need to call the number at the top of your old 401(k) statement and request "distribution paperwork." They should be able to email you a form to fill out but some old timey companies will send it snail mail.

2. Pick a new discount brokerage firm and hop online to set up a new IRA Rollover.

3. Fill out the paperwork and have them mail a check directly to the new financial institution where you set up the new IRA. (Don't get the check sent directly to you).

4. Wait a while for the money to make it to your new account. Sometimes it takes anywhere from 2-6 weeks. Call and check in if it's been more than a month. There might be something they're missing on your paperwork.

5. When the money is in your new account you'll need to choose the investments. This means that you have to actually login to the new account and decide which stocks/mutual funds/ETFs you want to buy, otherwise the money will be sitting in cash! We don't want that. (Another reason why I like Betterment is you choose an asset allocation — a stock to bond ratio — and then they immediately invest the funds when the money arrives. They save you this step).

Congrats! You did a very "adulty" thing. Celebrate by watching your favorite show on Netflix while sipping some bubbly.

The "Elf on the Shelf" is more popular than ever, and parents are getting tired of having to come up with unique and artsy hijinks for their adopted Elf to get into night after night.

Unfamiliar with "Elf on the Shelf?"Read here.

If you only have a few minutes, here are the basics: It's a doll Elf. Your family adopts him. He appears in a different spot in the house each morning, and reports good and bad behavior back to Santa in the North Pole.

It was a simple concept until Pinterest came around. Now it's a competition to see who can get the craftiest.

And from what we've heard, parents are over it.

Here are our favorite "Elf on the Shelf" scenes from Instagram, Pinterest, and beyond.

Seems kind of violent?

Bill Gates says that he reads more than 50 books a year. Out of all of those, the Microsoft founder and Bill and Melinda Gates Foundation head just selected six of the best titles he's read in 2015.

Here they are:

'Thing Explainer: Complicated Stuff in Simple Words' by Randall Munroe

In "Thing Explainer," Randall Munroe describes how everything from rockets to smartphones to the US Constitution work — using just the 1,000 most commonly used words in English.

Gates says that it's a "brilliant concept" because if "you can’t explain something simply, you don't really understand it."

And Munroe, a former NASA roboticist and creator of beloved web comic "XKCD," is just the guy to do it.

One of his favorite explanations is why microwaves — which Munroe calls a radio box — cook frozen foods unevenly:

When you put iced food in a radio box, after a while, parts of it start to turn to water. But since radio boxes are really good at heating water, those parts start to get hot really fast. They can even get so hot they start turning to air—before all the ice is even gone!

Not only does the book give you a better understanding of how the objects in our lives work, but it's a lesson in making complicated ideas relatable.

It's "a wonderful guide for curious minds," Gates says.

Buy it on Amazon for $16.71.

'Mindset' by Carol S. Dweck

Not all of Gates' favorites of this year were released in 2015. Stanford psychologist Carol Dweck's masterwork "Mindset" was published in 2006.

Gates says that "if you mistakenly believe that your capabilities derive from DNA and destiny, rather than practice and perseverance, then you operate with what Dweck calls a 'fixed mindset' rather than a 'growth mindset.'"

The fixed mindset is a "huge psychological roadblock," Gates says, because it means that you're going to do things that validate how gifted you are — and avoid the potential shame in doing things you're not immediately excellent at. It's the mindset that makes people say self-limiting things like "I'm just not good at math" or "I can't rock-climb" rather than trusting that, with enough effort, they'll improve.

Gates notes that the growth or fixed mindsets show up in different facets of his life — he might have a growth mindset around bridge, but he has a fixed mindset regarding basketball.

That's what's so useful about the book. It helps you examine the facets of your life with new eyes, Gates says, prompting questions like "Which areas have I always looked at through a fixed-mindset lens?" and "In what ways am I sending the wrong message to my children about mindset and effort?"

Buy it on Amazon for $9.54.

'The Road to Character' by David Brooks

Gates says that he found New York Times columnist David Brooks' new meditation on leading an ethical life useful for evaluating his own life.

Brooks talks about virtue in two ways: résumé virtues, the tasks you accomplish and the status you attain, and eulogy virtues, or the inner character that interacts with the outside world.

The task for us is to hear the calling of the eulogy virtues in the me-first world of social-media saturated consumer culture.

Brooks supplies a question to alert us to that voice: "What are my circumstances calling me to do?"
