Thrift-shopping is a great way to buy high-end clothing and accessories well below retail prices. However, when buying used items it's important to really think about your purchases.

Typically, any item that you can clean well is a safe bet. But some items that are difficult to clean and potentially carry harmful germs probably shouldn't be purchased from a secondhand store.

When you're shopping at a thrift store, you'll want to avoid these 12 items:

Children's safety equipment including cribs, strollers, and car seats.

When it comes to children's safety, you can never be too careful.

If you're considering buying a crib, stroller, or car seat secondhand, you'll want to thoroughly check these items for damage because, unlike with clothes, the faults on these items aren't always visible.

Because safety standards change frequently, it's essential that you do your research to see if the item you want to buy has been recalled, according to Duct Tape and Denim.

Duct Tape and Denim also notes that car seats are only built to last one car crash. Because it's close to impossible to know an item's past while you're thrift-shopping, buying a used car seat might not be worth the risk.

Helmets.

Like car seats, protective bike and motorcycle helmets are only built to withstand one impact, according to Duct Tape and Denim.

Because it can be difficult to know a used item's history, you're better off safe than sorry. Not to mention, helmets, like hats, can also be carriers for lice and other infections.

Electric appliances.

When considering purchasing used electronics, you should to test them out in the store to make sure they work properly, according to Bargain Babe.

Vintage appliances can be faulty and outdated, so it's best to make sure that they work before you spend money on them.

Etsy, the online marketplace where creative entrepreneurs can set up storefronts to sell their own products, launched in 2005 with the goal of creating an online retail space that would build a more fulfilling and lasting world.

So it's no surprise that its 200,000-square-foot headquarters in the Dumbo neighborhood of Brooklyn would be filled with toxin-free paint, salvaged wood, and furnishings purchased from Etsy sellers. In August, the eco-friendly office was recognized with an Excellence Award from the Center for Active Design. It was one of seven international winners. 

The roughly 500 employees that work in the Brooklyn office are free to roam the nine-floor complex, finding a comfy spot to set up camp and work remotely away from their desks.

Last summer, we got a tour of the refurbished building the Etsy team calls home — scroll ahead for the photos.

In 2016, Etsy moved from a 106,000-square-foot space to its new headquarters in Dumbo. The new space is a two-building setup that's nearly twice as big, at around 200,000 square feet.

Etsy signed a 10-year lease on the nine-story building.

Before the big move, the company sent surveys to its employees, asking them to name their preferences and needs for the future office. Quiet spaces such as this one were big on the list of requests.

Everything around us is becoming connected. As a result, we are seeing shifts in investments and returns. There is already a great demand for network expansion, cyber security and insurance. And generally, the prices of hardware will fall as IoT becomes less of a novelty.

All of this opens up a huge opportunity for everyone to make and save a lot of money. We will invest $6 trillion in IoT between 2015 and 2020, which will yield $12.6 trillion ROI over the next decade. Enterprise will make up the majority of the investment dollars, followed by government and consumer.

Warning: Spoilers for "Game of Thrones" season seven, episode four, "The Spoils of War." If you aren't caught up on the series, read at your own risk. 

When you play the game of thrones, you win or you die. There is no middle ground.

Now that we're getting closer and closer to the end of the series, that powerful quote from Cersei back in season one is proving to be true.

Any week, anyone can go, and anyone can lose or gain a lot of power.

In "The Spoils of War," there are significant power shifts, as Daenerys wins a major battle after a major loss last week, and Cersei's wins come back to haunt her. This week many characters made good and bad decisions, and they all had some consequences. 

Every week, we'll round up which character was the smartest, the dumbest, the luckiest, and more in our power rankings.

Here's the "Game of Thrones" power rankings based on season seven episode four, "The Spoils of War" in order of who won and who lost. 

SEE ALSO: The 12 biggest questions we have after this week's 'Game of Thrones'

The smartest: Bronn

Bronn's skills in battle and incredible instincts come together in the end when he saves Jaime Lannister from dying via Drogon breath. He also chooses not to reach for his bag of gold, which he drops during the battle, saving himself from likely destruction. 

The dumbest: Jaime Lannister

Tyrion was right in calling Jaime an idiot as he heads toward Daenerys and Drogon. He is clearly blinded by his love for Cersei. When will it end? 

The luckiest: Jaime Lannister, Cersei Lannister

Jaime is lucky Bronn saves him from turning into Drogon ash.

And Cersei is lucky that the money meant to pay the crown's debt to the Iron Bank makes it to King's Landing before Daenerys, Drogon, and the Dothraki attack the Lannister army. She's also lucky her beloved brother/lover didn't die defending her. 

Not all coastlines are created equal — unless you’re referring to these four destinations, whose award-winning restaurants, stunning hotels, and jaw-dropping ocean views do their coordinates serious justice.

Marlborough, New Zealand

Split between two islands, the country of New Zealand has — at 8,700 miles — one of the longest coastlines of any nation, not to mention some of the world's most dramatic landscapes. Marlborough, on the northeastern tip of South Island, is one of its most stunning coastal regions — if a bit under the radar. Sunny, rolling hills give way to the Marlborough Sounds, a collection of drowned river valleys flooded by the Pacific Ocean and home to dolphins, seals, and blue penguins (all can be taken in by boat tour). 

But sightseeing aside, no one comes to Marlborough without a taste of the land: the sauvignon blancs produced here put New Zealand winemaking on the map. A drive through sunny wine country passes seaside hamlets and hill towns between vineyards and is a perfect way to admire the inland landscape. Two worthy stops: Allan Scott Winemakers, in Blenheim, which is known for its chardonnays and rieslings, and Wairau River Wines, one of Marlborough’s oldest and largest family-owned wineries, which is loved for its restaurant. Come hungry as you'll want to go for locally-sourced seasonal recipes like Marlborough mussel chowder and lamb with mint, portobello mushrooms, and halloumi.

Goa, India

Chaotic Mumbai this isn’t. Goa presents the calmer side of India, a tropical paradise where travelers come to enjoy miles of golden beaches, lush green countryside, vibrant cuisine known for its spicy flavors and Indo-Portuguese influences, and famous all-night parties.

Chris Pratt and Anna Faris were generally regarded as one of the sweetest couples in Hollywood. They shared their love of dead bugs, their "ritual" of Pratt braiding Faris's hair, and her love of feeding him, even as he dropped weight for roles. 

That's why so many were stunned when the couple announced their split on social media. If you're hurting as much as we are, lick your wounds with us and take a look back at the couple's love story in happier times. 

2007: They met on the set of "Take Me Home Tonight."

Though the pair grew up in Washington state about 20 minutes away from each other, they didn't meet until they were both in Los Angeles and filming the movie "Take Me Home Tonight." 

Faris was still married to actor Ben Indra at the time and the pair has sworn nothing happened while she was still married. 

Though they made the film in 2007, the film was released in 2011 after being stalled for the depictions of cocaine use. Pratt shared their love story at the premiere, saying, "This is a pretty spectacular moment for us, to be able to come to this movie that we met on and fell in love making." 

2007: Anna left her husband and Chris said he always knew they'd be together.

Faris and Indra filed for divorce in 2007. Pratt said that he knew she was "The One"the moment they met and that once Faris was single, the two of them were going to be together. 

2007: They had an adorable dating period.

Pratt and Faris are two self-described goofballs and it make sense that while they dated, they showed that side off. 

Pratt recounted how before they were officially dating, he left pornographic magazines out and Faris didn't seem to mind. 

Once they began dating, Pratt also left out his framed African stick bug and Faris told The New Yorker she got emotional because she found someone else who collected dead bugs like she did. 

Faris and Pratt also had a day called "sex-text Wednesday" where they would designate time to sext each other, she told the AP. That came to an end when she sent a "small child" a text about getting drunk.

The United States is vast: 3.797 million square miles to be exact. Yet when it comes to choosing a vacation, we often limit ourselves to a tiny fraction of the country.

There are plenty of good reasons why we would want to go to Yosemite National Park in August, along with 600,000 other people, or skiing in Vail in the winter, with 1.6 million others, but for those prepared to go off the beaten track, there are a lot of lesser-known places that are well worth a visit, especially if you're looking to ditch the crowds.

We have put together a selection of our favorite underrated travel destinations – from cities to day trips and national parks, these are all places that deserve a bit more attention.

Fredericksburg, Texas

This rustic town in Central Texas was originally settled by Germans and named after a former Prussian prince.

Today, it's one of the state's hidden gems, with a mix of unique 19th-century German architecture, a German market square, and a luxurious wine region in the surrounding Texas Hill County.

Tongue Point, Washington

You'll find Tongue Point jutting out from the northern coastline of Washington State. At low tide, this a prime place to spot sea life and birds as you walk across to the outcropping.

Conveniently, there's a campground nearby, so you can stay and explore the stunning scenery or just swing by for a quick swim. 

Topsail Island, North Carolina

Topsail is a barrier island that stretches 26 miles along the coast of North Carolina. It's managed to stay low-key despite having some of the most beautiful beaches in the area, earning it rave reviews on TripAdvisor. 

If you want to avoid the normal hustle and bustle of other seaside beaches in summer, this is the place to visit. The average cost to rent a house for four people is $276 a night on Airbnb. 

Lighthouses have been guiding mariners to safety since 268 BC. 

While many of them have been rendered useless today, thanks to modern technology, they still brighten the shores with their beauty.

These are the 26 most stunning lighthouses in the world.

Lindau Lighthouse, Germany

Lindau Lighthouse is the southernmost lighthouse in Germany, and sits on Lake Constance. The medieval tower, built in 1856, even has a clock!

Tower of Hercules, Spain

This ancient Roman lighthouse, dating back to the late 1st century A.D, has gained recognition as a UNESCO World Heritage Site. It can be found towering over the entrance of La Coruña harbor in north-western Spain.

Low Lighthouse, England, UK

Low Lighthouse is the only active lighthouse in Burnham-on-Sea, England. The small wooden lighthouse is a popular photo-op thanks to its nine "legs."

Moving usually means leaving your old house behind.

A new tiny house, called the Koda, is designed to move with inhabitants.

A construction crew from Kodasema, the Estonian design firm that created the 269-square-foot home, can assemble it in less than 10 hours, and disassemble it in four hours.

Kodasema unveiled the home in late 2016. Now the team is building small villages of Kodas near downtowns in four cities: Tallinn, Estonia, Amsterdam, Netherlands, London, England, and Almere, Holland. The furnished houses will come in three different models: "Koda for Living,""Koda for Studying," and "Koda for Working." They will function as homes, classrooms, and offices respectively in the villages.

The first village will be in Tallinn, which the team expects to open in October 2017, cofounder Ülar Mark told Business Insider. 

Kodas are now available to order online in the four cities, with prices starting at €120,000 (or about $132,500). These owners will manage the homes for people who will rent them out for days, months, or years at a time. The rent will differ depending on the city, and how long guests live there. (For example, Kodas in Tallinn will cost $100 per night, or between $825 and $1,200.)

The company might expand sales internationally if Kodasema can manage to ramp up production, Mark said. Check it out below.

Kodasema's tiny home villages will be located in car parks near city downtowns. The first will be in Estonia's capital, Tallinn, and will feature seven Koda houses. One will serve as an office, another as a public art gallery, and five as rentable homes.

The team assembled each home in less than a day in July. Before the villages can open, however, they will need to go through four-month inspection processes by the cities. (Tallinn's already started this process.)

The Kodasema team is currently working on installing plumbing and electrical systems, as well as landscaping, which it expects to complete the week of August 7 in Tallinn. The site occupies about 11,000 square feet, Mark said.

One side of the Koda is made of four-layered glass, which Mark said is thick enough to insulate the house from noise and cold. If owners want privacy, they can close the floor-to-ceiling curtain.

While our favorite TV shows will always have a place in our hearts, there comes a time for every good program to bite the dust. Once in a while we can even sense it coming, like when plotlines just start to seem ridiculous after a while.

Many fans will stick around for good characters out of loyalty even when the plot of a previously great show is tanking, but if the actors people tune in to see exit stage left for good, shows can really suffer.

Some programs like Law and Order: SVU have managed to withstand the loss of some big names over the years, but others, like Community and Dexter, have not.

In lots of cases, popular TV shows kick the bucket when a beloved character leaves the show, whether out of the actor’s own volition, medical reasons, or even death. Tragedies become doubly sad when the world loses both a talented actor or actress as well as a well-loved TV show. Even when remaining talented cast members continue on without big stars, sometimes it just isn’t enough to sustain a show and it ultimately gets canceled.

Here are 16 shows that flopped after they lost big stars:

16. "Community"

Community was one of the most beloved comedy shows in recent history. The NBC program that looped a group of community college students together for a surprisingly fresh, irreverent 30 minutes of laughs lost Chevy Chase and never recovered.

Chase abandoned ship before season 4 even stopped filming, which wasn’t a huge surprise given his infamous rifts with the program’s creator, Dan Harmon. The loss of Chase wasn’t the only thing that sent the show to the cleaners. Donald Glover, who played Troy Barnes on the show, also left, leaving a series of sad notes explaining why on social media. Yvette Nicole Brown and Dan Harman himself also departed, and the show was canceled soon after, finishing out with a final sixth season on Yahoo!Screen.

15. "Chico and the Man"

It may have only aired for four seasons, but the NBC sitcom Chico and the Man was one of the earliest examples of a multicultural program bridging gaps between Americans of different backgrounds. It was far from without problems, but the show was popular due to Freddie Prinze’s portrayal of Chico Rodriguez. Prinze, who had Puerto Rican and Hungarian heritage, was a charismatic and funny actor as well as the father of modern actor Freddie Prinze, Jr.

Sadly, Prinze was also deeply depressed and struggled with addiction problems throughout his life. He shot and killed himself after filming an episode of the show at age 22. While writers attempted to continue the show without him, it flopped miserably when they replaced his character with a tween boy whom the Man (Jack Albertson) refers to as “Chico,” saying that “You’re all Chicos to me.” It was one of the show’s lowest blows.

Even after trying to insert some drama, a pretty actress, and other gimmicks, ratings dropped too low for the show to continue.

14. "The O.C."

Broadcast in 50 countries worldwide and considered a very popular pop culture phenomenon, Fox’s The O.C. was such a well-loved show that over 700,000 fans signed a petition against canceling the show in 2007. Viewers were intrigued by the rich lifestyles in Orange County and dramatic tension in the show, but the drama became so wildly outrageous with drug abuse and over-the-top scenarios that it had to be wrapped up with something dark.

The teen drama plummeted off a cliff when writers killed off Mischa Barton at the end of the third season and was never able to climb back up again.

Plenty of fans hated Barton’s character Marissa by the season finale, but that wasn’t shown in the ratings, which were in the toilet at this point. Despite the outpouring of love from fans who begged for the series to continue, low ratings ultimately resulted in the show getting canned.

One of the best Android smartphones you can buy now comes in a classy gold color.

OnePlus announced on Monday that it's released a "Soft Gold" limited edition of its OnePlus 5 phone. The company is only making the version in "select quantities," it said in a blog post. It didn't make clear exactly how many it plans to make.

The "Soft Gold" OnePlus 5 is only available in the base model of the phone, which comes with 6GB of RAM. That version was previously only available in a dark gray color. Despite the new color choice, the model's price will stay the same — $479.

The more powerful model, which comes with 8GB of RAM, is still only available in black. OnePlus said it has no plans to make a golden version of that model.  

Check out the new gold-colored OnePlus 5:

The "Soft Gold" edition of the OnePlus 5 has a matte finish that resembles the gold version of the iPhone 7.

It's the only color option for the OnePlus 5 that also includes a white front.

Before the "Soft Gold" OnePlus 5, you could only get the phone in "Slate Gray" and "Midnight Black."

August 7 marks the 200th day of President Donald Trump's tenure.

In his first six and a half months in office, the President has promised economic prosperity and a revitalization of American industry.

And he's boasted about his success — using the record-setting stock market, and an ongoing job-market recovery — to claim credit for energizing the U.S. economy. 

Trump is right that stocks are at a record, and job creation continues. What's wrong is the suggestion that this is reversing a decline that was in place before the new administration took office.

Business Insider took a look at how some key markets and economic indicators have responded to the new president in the first 1/8 of his term.

Stocks have risen steadily since Trump's inauguration, with the benchmark Dow Jones Industrial Average recently hitting the 22,000 mark for the first time.

Stocks have been slowly ticking up and hitting new highs on a regular basis since Inauguration Day, although they've generally moved at a somewhat slower pace than in the days immediately after the election.

Investors seem to be expecting a corporate-friendly agenda of tax cuts and deregulation, although ongoing troubles in the White House and the failure of the Republican-held Congress to pass a healthcare-reform law have taken some of the wind out of their sails.

This year's rally in stocks is part of an 8-year long bull market.

While the Dow saw a sharp upward spike in the wake of the election and healthy gains since Inauguration Day, the stock market has seen a mostly steady uptick since bottoming out in March 2009 in the wake of the financial crisis.

The US dollar has been on a downward trajectory since Trump's inauguration.

After rising quickly after the election, the dollar has seen several months of weakness and erased those gains as expectations for the US economy have faltered.

The president himself has weighed in on the dollar, telling the Wall Street Journal in April, "I think our dollar is getting too strong, and partially that’s my fault because people have confidence in me."

Sunday's "Game of Thrones"Loot Train Attack showed the Dothraki slaughter the Lannister army with the help of Dany and her dragon, Drogon. It was the show's largest battle sequence so far— even larger than last year's Battle of the Bastards— with complicated sequences to film mixing both visual effects and practical effects.

The addition of a dragon the size of a 747 didn't make things easier either.

HBO released an excellent behind-the-scenes look at the many details that went into planning and executing one of the show's most complex battles. While Dany and Drogon consisted of a lot of special effects, there were also a lot of moments that used practical effects.

From burning stuntmen on fire to having Emilia Clarke ride a contraption similar to a mechanical bull, keep reading to see what went into bringing Sunday's giant battle to life.

Tyrion looks over the battlefield conflicted between his Queen and his brother, Jaime.

In reality, he was looking at a piece of green screen.

There were a lot of men in place for the battle scene against Daenerys and the Dothraki.

On Monday, Tesla announced that it would issue bonds to raise $1.5 billion. 

This debt offering will be a departure from Tesla's previous fundraising vehicles. The ratings agencies didn't run for the hills though. S&P wrote:

We affirmed our 'B-' ratings on Tesla despite the higher debt leverage following the proposed offering to reflect its improved liquidity. The offering will provide the company with an adequate cushion to fund its upcoming maturities and significant capital expenditures (capex) over the next 12-18 months following the launch of its Model 3.

And Moody's commented:

The stable outlook reflects Moody's expectations that the shipment levels and profitability of the Model 3, combined with an adequate liquidity profile, will enable the company to materially strengthen its operating performance and credit metrics during 2018.

Tesla's debt is considered relatively high-risk. But the verdict from the ratings agencies is that taking on additional debt at this juncture reduces the overall risk to Tesla's balance sheet.

But borrowing more isn't the only way Tesla can raise funds. Here are 5 others and some pros and cons to each:

SEE ALSO: Tesla is making a risky move by issuing $1.5 billion in debt

SEE ALSO: FOLLOW US on Facebook for more car and transportation content!

Selling stock

Over the past two years, Tesla has raised more money by selling additional shares to investors. By and large, this has worked out well because while Tesla stock has surged and swooned, the trajectory has been mostly up. During the first half of 2017, shares gained 65%.

Those gains in the company's market value mean — very simply — that Tesla can raise more by selling stock today than it could six months ago.

The drawback to using the stock market as an ATM is that although Tesla gets funds, and the banks that assist in the equity raise get fees, existing shareholders see their stakes diluted. An ever-upward share price takes the sting away, but over the long-term investors might start to conclude that Tesla is taking advantage of them as they own less and less of the business.

Then again, this is a cash burning business and it always has been. 

Selling bonds

This is what Tesla is planning to undertake now in order to raise another $1.5 billion. The pros are that you don't sell more equity and keep existing shareholders undiluted. You also provide investors with an opportunity to pursue a higher yield if your debt hasn't earned the highest rating.

"Investment grade" debt is lower yielding, and so investors sometimes see it as a place to park money (it pays better than a money market account). Tesla's debt will have a higher yield, so there could be robust demand for it in the current low-interest-rate environment.

But debt can also be a burden. Too much debt means you spend capital that could otherwise be re-invested, paid out to shareholders in the forms of dividends of buybacks, or used for R&D. Instead, all that cash is going to service the liability.

And in bankruptcy, bondholders can fight to reclaim part of their investment.

Convertible debt — selling debt that becomes equity

Tesla has issued convertible debt in the past. The biggest pro is that this type of debt doesn't immediately dilute existing shareholders, and when people are bullish about a high growth company offering them the opportunity to buy stock in the future is an added incentive. 

The biggest con is that it can eventually convert, and the timing of the equity conversion isn't controlled by the issuer. It can obviously be a pretty good deal for a buyer, however. As an investor, you get the best of both worlds: a stream of payments of the debt and vindication for a long-term view if the debt later converts to equity with substantial appreciation. 

Figuring out how to start an email can be a real challenge.

"Many people have strong feelings about what you do to their names and how you address them,"Barbara Pachter, a business-etiquette expert, tells Business Insider. "If you offend someone in the salutation, that person may not read any further. It may also affect that person's opinion of you."

We had Will Schwalbe, coauthor of "Send: Why People Email So Badly and How to Do It Better," and Pachter weigh in on a handful of common email greetings.

The perfect way to start an email will depend on whom you're writing to, but in general, when you're writing a business email to someone you don't know well or at all, the experts say there's one safe choice — and a bunch you should usually avoid:

DON'T MISS: 21 unprofessional email habits that make everyone hate you

WINNER: 'Hi [name], ...'

If you want to make it a little more formal, you can always use the person's last name: "Hi Mrs. Smith, ..."

"The reason I like this one is that it's perfectly friendly and innocuous," says Schwalbe.

It's also Pachter's favorite. She says it's a safe and familiar way to address someone, whether you know them or not.

So when in doubt, go with "Hi."

GREETINGS TO AVOID IN MOST SITUATIONS: 'Hey!'

This is fine to use with your friends, but the very informal salutation should stay out of the workplace. It's not professional — especially if you're writing to someone you've never met, says Pachter.

Schwalbe agrees: "I can never get out of my head my grandmother's admonition 'Hey is for horses.'"

Also avoid "Hey there." It tells the person, "I don't know your name, but if I try to sound cool and casual, maybe you won't notice."

'Greetings, ...'

This is a good backup to "Hi, [name] ..." if you don't know the recipient's name. But you should always do whatever you can to find out that information.

The INSIDER Summary: 

• Taylor Swift's "girl squad" was huge during her 1989 World Tour, but we've seen less of them lately.
• Some of the members, like Selena Gomez and Lorde, are still close friends with Swift. 
• Others, like Kendall Jenner and Zendaya, seem to have drifted apart.

Throughout Taylor Swift‘s 1989 World Tour in 2015, the singer made #squadgoals a viral headline as everyone became infatuated with the enviable bond of her huge, glamorous group of friends. Swift’s concerts became a who’s who of A-list models, athletes, and actresses, and her Instagram feed (and her friends’) became albums for the groups’ fun-filled vacations and impromptu baking parties.

But as time passed, the visibility of Swift’s squad has dwindled tremendously. Her members’ Instagram feeds feature other friends, the high-profile parties have stopped, and Swift has taken a noticeable break from social media.

All this left us wondering: WTF happened, and which women are actually still in Swift’s squad? We took a closer look at each former member in an attempt to analyze where she stands with Swift now. Follow along, ahead.

Status: Not friends

Despite an appearance at a concert at Swift's 1989 World Tour alongside other supermodel besties like Gigi Hadid and Cara Delevingne, Jenner is not as close to Swift as fans might think.

Kim Kardashian confirmed that when the "Keeping Up with the Kardashians" star appeared on Andy Cohen's "Watch What Happens Live"to admit that Jenner is indeed not in Swift's squad. It might have to do with Kardashian's Snapchat exposure or that Jenner has formed her own supermodel squad, called the Super Natural Friend Group with "It" girls like Hailey Baldwin, who has made public her distaste for the country singer-turned-pop star.

Lorde

Status: Still friends

Amidst her social media hiatus, Swift dedicated one of three recent Instagram posts to Lorde, congratulating her in March when her single, "Green Light," debuted. In July, a Yahoo interview suggested that Lorde and Swift had fallen out based on her saying, "I don't hang out with these people at all."

The singer clarified her comments on Twitter, explaining that she is still good friends with Swift and that her comments were about the squad as a whole. "[The squad] was never some exclusive club or secret society, but a wide circle of people, some of whom I know, and some who I’ve never met, like most wide groups of friends," she tweeted.

It's easy to write off celebrity agelessness as the result of pure luck in the genetics department. But that wouldn't be totally accurate: Scientists say that up to 40% of the physical changes that make us look older are caused by non-genetic factors.

That means seemingly immortal stars must have a few anti-aging tricks that actually work.

Yes, celebrities have lots of disposable income, professional makeup artists, and Photoshop to aid them — but we pored through dozens of interviews and found that lots of them claim to preserve their youthful glow using simple, evidence-backed health habits. (In other words: Get ready to hear a lot about sleep, exercise, and sunscreen.)

Here are some totally doable anti-aging strategies from 17 famous folks who never seem to look older. 

Pharrell Williams has the world's simplest skincare routine.

In a 2014 interview with Time Out London, Williams asserted that he's definitely not a vampire, finally addressing the (half-joking) speculations of fans looking to explain his perpetually youthful appearance. 

"I'm willing to go on record as saying that I don’t drink people's blood," he said. "How do I stay so young-looking for a 40-year-old? I wash my face."

It's probably safe to say there are also some really good genes at play.

Victoria Beckham eats salmon — every single day.

Beckham revealed her dermatologist's perfect-skin advice during an interview with Net-a-Porter last year.

"I see a dermatologist in LA, called Dr Harold Lancer, who is incredible. I've known him for years — he sorted my skin out,"she said. "I used to have really problematic skin and he said to me, 'You have to eat salmon every single day.' I said, 'Really, every day?' And he said, 'Yes; breakfast, lunch or dinner, you have to eat it every single day.'"

It's not exactly clear what Beckham means by "problematic skin" (acne? rosacea? psoriasis? eczema?) so it's hard to say whether her dermatologist's advice is sound. But the fats found in fish do have anti-inflammatory effects in the body. Some research suggests they could help protect the skin against sun damage, too — but definitely don't use salmon as a substitute for sunscreen.

Jared Leto is a vegetarian who never skimps on sleep.

"It's probably just down to sleep and diet,"Leto told GQ in 2013, when asked how he looks like he's still in his 30s. "If you travel long haul a lot or don't sleep much, it's not going to last very long, that's for sure."

And for what's worth: small of handful of studies has shown that sleep deprivation can make people look older.

Leto also noted he's been on a vegan/vegetarian diet for about 20 years. It's an eating pattern that — done right — is linked to lots of health benefits.
