15 Secrets of Commercial Divers

Imagine some of the most physically demanding jobs available—supply line installation, construction, welding—and then imagine doing them underwater. That’s the life of a commercial diver, a rigorously trained professional who undertakes everything from bridge repairs to oil line maintenance. To get a better sense of this often difficult and dangerous work, Mental Floss spoke to several commercial divers for their thoughts on everything from the perils of decompression to swimming in sewage. Here’s what they had to say about a life in flippers.

1. DIVING DEEP CAN PRODUCE EUPHORIA (AND A WEIRD VOICE).

Commercial divers receive specialized training—either in the military or at diving instructional schools—to learn how to function hundreds of feet below the surface. The lower a diver goes, the more water pressure increases, and the greater the challenges. Jeremy, a commercial diver out of Louisiana who repairs and installs equipment for oil companies, says that working in such conditions can lead to physical exhaustion, pulled muscles, and a feeling of pressure on the lungs.

Plunging to a depth in excess of 100 feet can also result in nitrogen narcosis, which some refer to as "raptures of the deep" or the "Martini effect." It's caused when divers receive a higher concentration of nitrogen from their air supply due to the effects of the water pressure on the gas. (The air systems that commercial divers use allow them to breathe normally by providing air at a pressure equal to that of the water, but the lower they go, the denser the gas gets, and thus the higher the concentration.)

“It makes you feel drunk or euphoric,” Jeremy says of the narcosis. “The solution is to switch from a nitrogen-oxygen supply to helium and oxygen.” That cures the over-inhalation of nitrogen, but when a diver comes back to the surface or to a decompression chamber, their voice will be altered. “It’s an Alvin and the Chipmunks thing,” Jeremy explains. Some diving teams will use voice augmentation to de-scramble the high-pitched squeals when divers are communicating with the surface.

2. ABOUT HALF A DOZEN OF THEM DIE EACH YEAR.

Most commercial diving is centered around underwater construction—often repairing or replacing infrastructure that facilitates water, oil, or electrical supplies. Divers are frequently charged with digging trenches to bury electrical lines using high-pressure water blasts to excavate the ocean floor. If these trenches collapse, it can result in a catastrophic situation; the cave-in can trap and bury a diver, clogging their regulator or causing them to take off their helmet in a panic, which eliminates their air supply. Jeremy says a number of divers die every year in such cave-ins.

If divers can avoid that fate, they still have to worry about a number of other ways they can meet an untimely end. “We use cranes and those can fall or drop their load on you,” Jeremy says. Cutting into “live” pipelines can also cause explosions, as can using tools that displace hydrogen from the water. In an enclosed space like a ship or supply pipe, that collected hydrogen could catch a spark and explode. “That could blow your helmet off or into pieces,” he says. All in all, 25 commercial divers died on the job between 2011 and 2014, according to the Bureau of Labor Statistics; another 310 suffered nonfatal injuries or illnesses.

3. THE DEEPER THEY GO, THE MORE THEY EARN.

Diving jobs vary in pay according to risk, duration, and other variables, but generally, a diver’s base pay is usually supplemented with “depth pay.” The further down they go, the more they can make.

“It’s basically about a dollar a foot,” Jeremy says. “After 150 feet, the price can double to $2 a foot. Added on to regular pay, a 12-hour day can add up.” A diver working at 300 feet might net $1000 in a shift. Saturation divers, who can go 1000 feet down and are required to live off-shift in a chamber pressurized to the surrounding water in order to avoid decompression sickness, or the “bends,” can make even more.

4. SOMETIMES THEIR SUITS ARE HEATED.

Going deeper into the water means enduring more frigid conditions. To offset plummeting temperatures, divers need a way to keep their suits warm. “Below 80 feet, it gets cold,” Jeremy says. “We either pump water into a wet suit or wear a hot-water suit.” The former allows water to come in and make contact with the diver's body, typically from a heated source at the surface; the latter has water channels throughout the suit that branch out and keep divers from getting too cold. Because hot water suits can maintain a more consistent temperature than delivering warm water from above, they are most often used at 200 feet and lower depths.

5. THEY CAN WIELD FIRE UNDERWATER.

Most tools meant for underwater use are hydraulic (involving the use of water or other liquids), since they’re largely unaffected by water pressure. Fuel-powered or pneumatic tools (those that involve the use of gas) don’t really work, but divers can still make use of jackhammers, chainsaws, and other devices you’d find in an above-ground construction job. Others, however, need to be adapted.

“In my opinion, the most interesting adaptation is the BROCO torch,” says Brian, a diver based in New England. The BROCO torch uses direct current to ignite a magnesium rod and oxygen mixture that burns at approximately 10,000 degrees and can cut through metal like butter, even underwater. (A/C, or alternating current, is what we use in our homes—but because the direction of the current reverses many times a second, Brian explains, it can freeze the diver in place while electrocuting them, making it too dangerous for underwater use.)

6. THEY MIGHT FIND DEAD BODIES.

According to Jeremy, many recovery dives for people suspected of drowning fall under the purview of local law enforcement. Still, commercial divers can encounter someone who’s wound up in a watery grave. “I’ve done helicopter recovery jobs,” he says, referring to crashed aircraft that can harbor passengers. Once, while working on an oil rig, he stumbled upon a dead scuba diver. “It was more of a skeleton in a scuba suit,” he says. If a diver does find a corpse, they're unlikely to ever know the history of how the body got there; such discoveries are required to be passed on to the Coast Guard for investigation.

7. THEY CAN WIND UP FEEDING FISH.

“We encounter marine life all the time,” says Mike, a commercial diver who now works primarily in and around the Great Lakes. “When working the ocean, if we are cleaning off marine growth, sometimes you will get some fish that come up and eat what you are cleaning off.” Mike says that commercial divers frequently spot sharks, barracudas, and other potentially dangerous sea dwellers, but the animals generally don't care much about humans. They’re even less likely to approach if the workers are using torches.

8. THEY SOMETIMES SWIM IN UTTER FILTH …

A common component of commercial diving, HAZMAT (hazardous material) diving involves working in contaminated water. That could mean anything from a lake affected by nearby lawn chemicals to checking equipment at a nuclear reactor. If it could kill or poison you, a diver has probably swum in it.

This kind of work requires a special approach. Brian says that those who venture into higher-risk HAZMAT diving usually wear a positive pressure diving helmet; since the pressure inside the helmet is greater than the pressure in the water outside, the helmet helps keep hazardous material from entering. HAZMAT divers also wear a rubber dry suit that fully seals the diver's entire body, unlike normal wet suits, which allow water to make contact with the wearer. Support staff will also decontaminate the HAZMAT diver after the job, scrubbing their suit free of harmful materials before the diver undresses.

9. … INCLUDING SEWAGE.

Those stories you may have heard about people diving into sewage treatment plants to repair equipment? Those would be commercial divers, who occasionally brave the psychological challenge of being submerged in poop. Because it's usually impossible to see in a sea of feces, divers will study reference photos of empty tanks before going in. They'll suit up in sealed dry suits and typically will weigh themselves down in order to sink through the dense liquid; once they're in position, they work by feel. “Both the sewage jobs I dove on, it was repairing a masticator blade,” Mike says. “Picture a giant blender that makes solids less solid. I don't do it anymore because of the health risks.” A rip or tear in a diver's suit can introduce a litany of dangerous bacteria into their body: In addition to your standard Salmonella and Cryptosporidium parasites, such vile muck can also harbor hepatitis, Norwalk virus, E. coli, and assorted fungi [PDF].

10. DAWN SOAP IS A LIFESAVER.

Dawn dishwashing liquid is a must-have on diving expeditions. It can get diving suits and skin free of oil, and can even help divers cope with parasitic pests. When Jeremy was working on a mile-long pipeline near New Orleans, the shallow water resulted in workers getting infested with parasites carried by nutria, a semiaquatic rodent. “The hookworms will dig into your skin, die, and leave a big red mark,” he says. Splashing Dawn soap gets rid of the itch immediately. (If irritation persists, divers might need to seek anti-inflammatory treatment from a dermatologist.)

11. THEY WORRY ABOUT BEING SUCKED INTO A VACUUM OF DEATH.

Divers are frequently in violation of the laws of nature. Humans, after all, were never meant to thrive (or survive) underwater, particularly at more pressurized depths. Many divers fear encountering Delta P, or differential pressure—a vacuum that’s far higher in pressure than their current environment, and is created by intersecting water bodies as a result of opening a channel like a pipe. “Delta P is vacuum-like suction much like you would imagine from when the cabin of an airplane ruptures, but at a much greater magnitude,” Brian says. “It can be very difficult to detect until you are already too close, and can trap the diver at depth or even kill them instantly.” The unfortunate crab in the video above is an example of how differential pressure can ruin your day.

12. THEY SOMETIMES GO DIVING INSIDE WATER TOWERS.

Those water towers you see in populated areas that stand on stilts hundreds of feet up in the air? Townships need to periodically check them for sediment levels to maintain water quality. That’s when they call in a commercial diver, who needs to add "not afraid of heights" to their skill set. “You have to climb all the way up, get into your wet suit, measure the sediment with a ruler, and clear it out with a [suctioning device called an] airlift." Jeremy says. And that's not the only lofty prospect for a diver: Jeremy notes that some oil rigs stretch 100 feet in the air. Divers without seniority may be expected to carry out repairs or work at or near the top, instead of actually diving.

13. THEY CARRY KNIVES.

No, it’s not to duel with sharks. “While diving, I carry a razor-sharp knife for emergency purposes only,” Brian says. In an urgent situation, it could be used for "cutting anything from old fishing line to my own dive umbilical—the air hose and lifeline.” The latter rarely happens, unless the diver gets it snagged or it becomes compressed. In the event of a hose failure, divers have a "bailout bottle," a supplemental tank they can switch to in case of emergency.

14. THEY CAN BE UNDERWATER BUT NOT ACTUALLY IN THE WATER.

Not every dive requires divers to swim while working. For jobs that require meticulous attention to detail for repair or where welding is required, diving teams can set up positive pressure habitats that isolate the problem area and allow the diver to work out of water. “You use air pressure to push water out of the habitat, which is in two pieces,” Jeremy says. Inside, a diver would trade their helmet for a welding mask. Because it can take a day or more to set up the habitat for a job that might take only one or two hours, habitat work is used only in cases where there aren't any other options.

15. THEY STILL GO SWIMMING FOR FUN.

Like anything done recreationally, diving can begin to seem routine if it's performed on a daily basis. While some divers get their fill of water by working 12-hour days for weeks at a stretch, some still enjoy going under in their free time. “While my career has definitely diminished the novelty of being in such an alien environment, I still love to dive recreationally,” Brian says. “Commercial diving is exhausting work, typically in dark, low-visibility water with a particular task in mind, while recreational diving is often more about exploration and sight-seeing. I would argue that the difference is not unlike a professional runner going on a beautiful hike in their free time.”

13 Secrets of Substitute Teachers

Whether they’re recent college graduates or retirees, substitute teachers are a diverse bunch with a range of academic specialties and skills. No matter their background, they often arrive at work unsure of exactly who and what they’ll be teaching—but they usually have some tricks up their sleeves to get oriented quickly. Mental Floss spoke to a few subs to get the inside scoop on everything from why they love pregnant teachers to how they spot troublemaker pupils.

1. Morning people get more substitute teaching jobs than night owls.

Substitute teachers must be willing to have a (very) flexible schedule, and it helps if they’re morning people. As early as 5:00 a.m., subs get a phone call—automated or from someone who works in the school’s office—offering them a job for that day. If they accept, they have an hour or two to get out of bed, get ready, and report to work. Some schools now use an email notification system, but early morning phone calls are more effective given the time-sensitive, often unexpected nature of substitute teaching.

2. First impressions are important when it comes to substitute teaching.

According to Kevin, a substitute teacher who works at schools in Southern California, dealing with new groups of students can be challenging. “It’s very hard to establish authority in the classroom. As a newcomer, you’re the foreigner,” he explains.

To immediately establish their authority, some substitute teachers practice speaking with a powerful voice, exhibit confident body language, and shut down any disruptions swiftly and decisively. But no matter how confident a sub is, some students will take advantage of the teacher’s unfamiliarity with the class. “It’s hard to write up a student who you can’t name. In a high school setting, you usually get 30 to 38 students a period for five or six periods. That’s a lot of students who may or may not want to test their bounds that day,” Kevin says.

3. Subs are an eclectic bunch.

Substitute teachers range in age from recent college grads working toward their teaching certification to elderly retired people. But what unites them is a love of teaching. Beverly, a substitute teacher who has taught for over 56 years, says that subbing keeps her sharp and active. “I do it for mental stimulation and because it’s a terrific service. You have to stay stimulated and involved with people,” she says. “I find youngsters to be so forthright and honest. The kids light up my life.”

Besides being a variety of ages, substitute teachers also come from a variety of professions. “You can’t believe how many teachers used to be lawyers but couldn’t stand it,” Beverly says. Everyone from former nurses and flight attendants to chemical engineers have earned their teaching certificates and become subs, bringing their real-world experience into the classroom.

4. There's a reason a substitute teacher's face might look familiar.

In schools in Los Angeles and New York, many struggling actors work as substitute teachers because they can balance teaching gigs with auditions and short-term film shoots. Like actors, subs must be able to speak in front of groups of people, improvise when they don’t have good instructions, and be quick on their feet when something goes wrong.

5. Substitute teachers aren't a fan of school holidays.

Because substitute teachers don’t have a set salary and work one day at a time, many of them face financial uncertainty, especially when holidays roll around. “Holidays can be devastating financially,” Kevin explains. When a school has the whole week of Thanksgiving off, subs don’t see that as a chance to relax. “In reality, a quarter of your paycheck for that month is gone,” Kevin says. “When you have student loans, insurance, etc. to pay, that extra little bit taken off your paycheck may mean you’re just scraping by.”

6. Substitute teachers have tricks to learn names quickly.

Facing a classroom of unfamiliar faces can be daunting, but subs have a few tricks up their sleeves to memorize student names in a flash. While some subs make seating charts as they take attendance, others use mnemonic devices to remember troublemakers’ monikers. Beverly admits that she doesn’t use anything fancy, but because she substitute-teaches math and science classes at the same school, she sees the same kids year after year. “I see the same youngsters out of junior high and into high school, but I do have a seating chart as well. They’re always amazed when I know their names,” she explains.

7. They love pregnant teachers.

Subs seeking job stability hit the jackpot when full-time teachers get pregnant. “At the school I currently work at, there’s a woman who is subbing for the whole semester for a second grade teacher who is out on maternity leave,” says Kyle, a science teacher who worked as a sub before getting a full-time teaching gig. Besides pregnancies, long-term health challenges and injuries can present an opportunity for subs to get a steady gig. Beverly says she once took over for an entire semester because of another teacher’s broken hip.

8. Some substitute teachers are quite familiar with busywork.

Novelist Nicholson Baker, who wrote about his experience going undercover as a substitute teacher at six schools, describes the astonishingly large amount of busywork that subs must assign students. “I passed [work sheets] out by the thousands,” he noted in The New York Times.

While Baker laments the “fluff knowledge” and vocabulary lists that subs are expected to force students to memorize and regurgitate, some subs do teach lesson plans. Kyle, who has a math and science background, explains that some teachers felt comfortable with him teaching the lesson plan so the students wouldn’t fall behind. “I’d teach it and assign homework accordingly for what we covered in class,” he says. But he admits that for middle school or non-science classes, he would sometimes simply be given a video to show the kids, or a work sheet or quiz to pass out.

9. The reputation of a substitute teacher can precede them.

Once a sub has taught at the same school a few times, they can develop a reputation—good or bad—among students. “When I first started subbing, I was 23 or 24, so I wasn’t much older than these kids—especially the seniors—and I think they saw me more as a peer than an authority figure,” Kyle explains. “I thought if I kept a light and fun atmosphere, kids would show their appreciation with respect. But that’s not how kids’ minds work. If you give a little, they’ll want more. So I became stricter and sterner as I went on,” he adds.

10. Substitute teachers can often spot troublemakers fast.

Although it might seem obvious which students are talking out of turn or giving the sub a hard time, substitute teachers have another way to quickly identify any mischievous students. “Usually, if a teacher has a really outrageous student, they’ll leave a note of warning for the sub. Sometimes the teacher will also leave a list of who the helpful students are,” Beverly says.

11. Substitute teachers may deal with inappropriate student behavior.

Kyle says that due to his young age and easygoing nature, some students tried to push the boundaries and act inappropriately with him: “[Students] would talk about or say things in front of me that I know they would never say in front of a teacher. I was once asked to party with some of the kids. Girls would try and flirt with me.” While male students typically tried to talk to him about basketball, female students frequently asked him if he had a girlfriend. “I would lose control of classrooms sometimes. Kids would get very wild, and sometimes would say inappropriate or abusive things to other students without fear of discipline,” he admits.

12. Substitute teachers are honored on a special day in November.

The National Education Association established the annual Substitute Educators Day on the third Friday in November to honor subs around the country. Besides bringing awareness to the work that substitute teachers do, Substitute Educators Day supports subs in trying to get health benefits, professional development, and fair wages.

13. Substitute teachers can make lasting impressions on their students.

Although most subs don’t see the same kids day after day, they can have a meaningful impact upon their students’ lives. “As an outsider, especially a younger teacher, students will often listen to you as someone who recently was in their shoes. Sometimes you talk to them one-on-one and give them a new perspective on why they should care about their schoolwork,” Kevin says.

And some students listen to their sub’s advice on studying and planning for the future. According to Kevin, students have approached him as he walked down the halls to thank him for encouraging them to get better grades.

“These experiences are few and far between, but it’s crazy to think that even these small talks with students can actually have a lasting impression,” he says.

13 Secrets of Tattoo Artists

Tattoos have gone mainstream: what was once considered a mark of rebellion abhorred by grandparents has become more like a rite of passage. Today, about 30 percent of American adults have at least one tattoo, and among millennials the number jumps to almost 50 percent.

So it’s a good time to be in the tattooing business. But no matter how up-close and personal you get with your tattoo artist, there’s still a lot about the job you probably don’t know. We talked to a few seasoned experts about the intricacies of inking.

1. Tattooing is really hard to break into.

Today there are more than 15,000 tattoo parlors in the U.S., compared to roughly 500 professional tattoo artists operating in 1960. But while the industry is booming, it’s difficult to get your foot in the door. The first step is to get an apprenticeship under a reputable artist who will teach you all they know, but that can take years of persistence.

“I just now have an apprentice and he’s been bugging me about it for three years,” says Chad Leever, a tattoo artist in Indiana. His best tip for landing an apprenticeship? “Hang out, get to know us, get tattooed, but even then it will probably still be no. It’s really tough.”

Tattooing has been an exclusive and secretive industry for years. The “every man for himself” culture has roots in the early days of tattooing when an artist had to protect the tricks of their trade. Sailor Jerry, for example, was known for his vibrant ink shades and Japanese-inspired designs. Captivated by his work, other artists would ask him how he concocted such brilliant colors on the posters in his shop, and Jerry would tell them to add sugar water to the ink. The copycats would realize they’d been sabotaged when they found their posters full of holes—eaten by cockroaches attracted to the sugar.

“Everybody has their secrets and they don’t wanna tell anyone else,” Leever says. “You have to earn the right to gain the knowledge.”

2. Tattoo apprentices get hazed.

If you miraculously manage to land an apprenticeship, get ready to grovel. “Being an apprentice, we can make you do anything,” Leever says. During his own apprenticeship, Leever had to get his navel pierced. “They picked out the most ridiculous navel ring,” he says. “It was this colorful rainbow thing and I had to leave it in for 10 days and show every person who came into the shop. It was horrible.”

Rituals like these are meant to test how far an apprentice is willing to go for the job. “It’s tough but you’re gonna find out if someone’s gonna make it or not based on how much they wanna sacrifice for this career,” says Bang Bang, a celebrity tattoo artist in New York City and author of the book Bang Bang: My Life In Ink. “Do you love it or do you just wanna be part of the show? You have to prove you are just the humble, humble student.”

3. Tattoo artists practice on themselves.

It may be years before an artist-in-training gets to wield a tattoo gun. When they finally get their first shot at inking some real human skin, it’s often attached to their own body. “I just had my apprentice tattoo himself,” Leever says. “It was terrible tattoo. It turned out horrible. He messed it up and he’ll learn from that but now things will make more sense the next time he does it.”

Occasionally they’ll get to tattoo their close friends or even their teacher. Bang Bang says he was the subject of his apprentice’s first tattoo attempt. “If I’m not brave enough to get it, how can I suggest other people do so?” he asks. “I wanted to show them I believe in you, you can do this.”

Other non-human practice materials include orange peel, faux skin, and pig ears.

4. They agree with your parents.

If you’re looking for support for your burning desire to get a neck tattoo, you probably won’t get it from your local tattoo parlor unless you’re older and have a steady job. A lot of artists flat-out refuse to tattoo necks, faces, and hands for young people because they know it could affect the rest of their lives.

“I don’t feel like at 18 you understand the risk of that,” Leever says. “That’s huge. I feel from a moral and ethical standpoint, I could do this and get paid however much, but totally change or ruin this kid’s life.”

According to one survey, 61 percent of HR managers said a tattoo would hurt a job applicant’s chances of getting hired. “People are like that’s money you turn away,” says Jeffery Page, a California-based tattoo artist, “but it allows me more time to do something more positive. Otherwise you’re screwing that person out of at least half of their job opportunities.”

5. A good tattoo artist will say no.

Whatever your age or employment status, there are some tattoos artists just won’t do, either because it’s not their specialty or they know it won’t look good or heal well. The professionals will be honest about this.

Small, intricate designs might not age well, and finger tattoos won’t last. A good artist will warn you about these potential complications and maybe even refuse the work. Because so much of their business relies on referrals, their art is an advertisement, so it better be good. “A good artist will tell you no because your money is not worth their name,” says Page.

But this isn’t always true, especially for less-experienced artists looking to make as much money as possible. “They probably didn’t train under somebody that taught them well,” Leever says. “It’s become this cash-cow industry where people open up a shop that know nothing about tattooing and hire a bunch of people who don’t know anything about tattooing and it’s just about making money.”

6. Tattoo artists hate it when you don’t look at their portfolios.

One big pet peeve of artists is when customers don’t even peek at examples of their work before asking for a tattoo. This is a little bit like hiring an interior designer to revamp your home without looking at their previous designs or at least checking out their Yelp reviews, except a lot more permanent.

“I want my work to sell itself,” Leever says. “I want you to look at this and realize, yes I am the one for you.”

This is also a sign a customer hasn’t done their research, another pet peeve. “If you’re in such a rush to get a tattoo that you can’t look up a person, then you probably shouldn’t be getting it done,” says Page.

7. They’re tired of infinity symbols.

Tattoo trends come and go, but this one just keeps hanging on. According to Leever, there’s been a huge increase in requests for the infinity symbol (which sort of looks like the number eight on its side) over the last few years. “A guy I worked with did four or five in one day,” Leever says. “It’s a poor, boring design. Maybe it’s on Pinterest or something.” Indeed it is, but it’s also on a lot of celebrities, including Kristen Stewart and Taylor Schilling. And celebrities have a huge influence on tattoo trends.

“When Megan Fox got lettering down her ribcage, it seemed like for a whole year we’d have girls come in asking for messages down their ribcages, saying it means a lot to them,” says Page. “But they never would have gotten the message on the ribs, because it’s more of a painful area, [except] the fact that she had it meant it was a cool summer addition to their body.”

8. They make mistakes all the time.

They just know how to cover them up so the customer never knows. “Every tattoo artist messes up,” says one artist on Reddit. “We just take the time to fix it as we go, adding a flourish here or there, a little bit more contrast. No client would notice.”

9. You can barter with them.

Not all tattoos must be paid for in cash. “I actually love bartering, because both parties involved always get what they want,” says Leever. “No money exchanged, makes it easy. The best barter I've been involved in would probably be when I received a 1977 Kawasaki KZ750 motorcycle with a sidecar. It was quite the deal.”

10. Men have the lowest pain tolerance.

Women handle having their skin pricked with needles over and over again much better than men do, according to Page. “Usually the funny thing is, the more alpha male the guy is, the less of a pain threshold they have,” he says. Leever tells the story of a man who wanted a “tough guy Metallica tattoo” but who couldn’t handle the pain. He left the shop with a single line trailing down his bicep.

11. Cover-ups pay the tattoo shop bills.

The tattoo industry is self-sustaining in many ways. For example, people rarely stop at just one tattoo. According to the Pew Research Center, about half of millennials with tattoos have more than one, and 18 percent have six or more [PDF].

But there’s also a lot of cash to be made in covering up old designs. “I make more money from guys down the street than from new customers,” says Leever, meaning bad tattoos from his competitors. “There’s always a name to cover.” And speaking of names …

12. There are only three names you should ever have tattooed.

According to tattoo artists, if you’re going to get a name inked on your body forever, it should only belong to your pets, your kids, or a dead relative.

13. The bodies of tattoo artists take a beating.

“If your back’s not hurting, you’re not trying hard enough,” Bang Bang says. “I have a bad neck now after many years of being hunched over. Back problems are really common, as are hand and neck and eye problems. It takes a toll.”
