Here's What You Need to Know Before Getting Inked or Pierced, According to Doctors

Getting inked or pierced is a rite of passage for many teens and young adults. But before getting that belly ring or butterfly on your back, experts want you to be aware of the risks, which are reviewed in a new clinical report from the American Academy of Pediatrics (AAP). According to NPR, it's the first set of recommendations the professional association has ever released on the practices.

Forthcoming in the October 2017 issue of Pediatrics and available online, the report provides a general assessment of the types and methods used to perform body modifications, along with potential health and social consequences. Here are a few main takeaways:

—It's unclear how often tattoos cause health complications, but they're generally believed to be rare, with the greatest risk being infection. One recent study found that nanoparticles in ink can travel to and linger in lymph nodes for an extended period. That said, you should check with your doctor to make sure all of your immunizations are up to date before getting either a tattoo or piercing, and that you're not taking any immunity-compromising medicines.

—Before shelling out your hard-earned cash on a tattoo, make sure it's something you'll likely still appreciate in five to 10 years, as it costs anywhere from $49 to $300 per square inch to remove a tattoo with lasers. (This might provide all the more incentive to opt for a small design instead of a full sleeve.)

—About half of people 18 to 29 years of age have some kind of piercing or tattoo, according to Dr. Cora Breuner, who is chair of the AAP committee on adolescence. Many individuals don't regret getting one, with some reporting that tattoos make them feel sexier. But while millennials appear to be cool with metal and ink, hiring managers might not be too pleased: In a 2014 survey of 2700 people, 76 percent said they thought a tattoo or piercing had hindered their chances of getting hired, and nearly 40 percent thought tattooed employees reflected poorly on their employers.

—Not all tattoo parlors are created equal, as each state has different regulations. Keep a close eye on whether your artist uses fresh disposable gloves, fresh needles, and unused ink poured into a new container. This helps prevent infection.

—The advice is similar for getting pierced: Make sure the piercer puts on new, disposable gloves and uses new equipment from a sterile container. Tongue piercings can cause tooth chippings, so be careful of that—and remove any piercings before you play contacts sports.

9 Amazon Prime Perks You Might Be Missing Out On

From diapers to camera equipment to jewelry, you can buy just about anything on Amazon and have it delivered to your doorstep in a matter of days—or in some cases, even hours. If you buy from the retailer often enough, its Prime service, which offers free two-day shipping, will save you far more than the $119 it costs to subscribe.

Your Prime membership offers a lot more than free shipping, though. To get even more out of Prime, don't forget to take full advantage of all its extra perks.

1. Photo Storage

One of the most convenient perks of your Prime membership is unlimited photo storage on Amazon Drive. You can add photos from your phone or computer and access them from your devices. You also have the option to back up those photos automatically with the Amazon Photos app. This way, you can free up precious storage space on your phone. Amazon says it doesn't adjust or reduce the quality of your images, either.

In addition to unlimited photo storage, Prime members also get 5 GB of data storage for free, which is useful for saving videos and other files.

2. Grocery Delivery

With Prime Pantry, you can skip the supermarket and have grocery staples delivered to your door. For a flat fee of $5.99, you can order all the kitchen, household, and pet care items you can fit in a box. Each time you add an order to your virtual Pantry box, Amazon will tell you how much room you have left. And if the order is over $35, Prime members get free delivery.

3. Music, Movies, and TV Shows

Prime members also get access to Prime Video, where they can find a huge selection of free movies and TV shows, including its original programming. Similarly, Prime Music includes a massive collection of streaming music from top artists. The songs are ad-free and you can download them to your device in order to listen to them even when you’re not connected to data.

Prime also gives away free entertainment credits via its “no-rush shipping” option. Your Prime membership comes with free two-day shipping, but if you choose a later delivery date, you can score digital credits toward eBooks, music, videos, and apps.

4. Free Kindle eBooks

If you're a Prime member with a Kindle e-reader or Fire tablet, you also have access to the Kindle Owners' Lending Library. It's like a digital public library that offers access to hundreds of thousands of books.

The catch is that you can only borrow one title a month, and the available titles change every month. However, there are no due dates, so if it takes you a few months to finish a book, you don't have to worry about late fees.

5. Steeper Discounts on Some Products

If you have a young child or infant, you can score discounts on supplies with Amazon Family, which offers 20 percent off certain product subscriptions (like diapers and baby food) through Amazon Subscribe & Save. If you use Amazon Family to register for gifts, you also get a 15 percent completion discount on some items, which basically means you'll get a price cut on any items left on your registry.

Even if you’re not a parent, Amazon's Subscribe & Save option can help cut the cost of certain products. You get up to 15 percent off household items when you opt to receive at least five of those products periodically—you set the schedule, so you decide whether that new bag of dog food is delivered every week or month.

6. Early Access to Deals

Amazon's Lightning Deals can be hit or miss, but if you have Prime, you can scope them out early. Amazon allows Prime members to check out what's on sale 30 minutes before anyone else, which can help you snag popular items that will sell out fast.

And on Amazon Prime Day, Prime members are privy to even more deals.

7. Two-Hour Delivery

If you need something in a rush, Amazon will ship items from local stores, depending on your Zip code, with free two-hour delivery. This service is called Prime Now, and it is, of course, only available to Prime customers. It includes over 10,000 items, many of which are household staples like cleaning products, toiletries, and food. However, it also includes some electronics like video games, chargers, and computer accessories.

After acquiring Whole Foods in 2017, Amazon has added the grocery chain to its Prime Now service in select cities, too. They're testing Whole Foods delivery in a number of major metro areas before rolling it out nationwide.

8. Twitch Prime

Twitch is a live video streaming service for gamers. And since Amazon purchased the company in 2014, you can now get Twitch Prime membership for free with Amazon Prime.

Each month, Twitch members get "free game loot," which includes access to a new game. You can also watch other gamers stream their videos ad-free, and you get one free channel subscription every 30 days. If you already have Amazon Prime, you simply need to link your account to Twitch Prime.

9. Amazon Elements

For the socially conscious shopper, Amazon launched Amazon Elements, a shopping portal that includes a line of "premium products."

With Amazon Elements, Amazon only partners with suppliers that meet its "high-quality and safety standards." For now, the selection of products on Elements is scarce. Categories are limited to vitamins and baby wipes. You can dig deeper into the sourcing of these products, though, and review the item's quality report as well as ingredient and product origins via the Amazon app.

University of California and McMaster University Are Offering Their Learning How to Learn Course Online for Free

If you've ever stayed up late cramming information the night before an exam, it probably didn't go well. Or maybe you tried doing the right thing by spending days or even months studying a subject, only to realize you weren't retaining the information. These failed attempts may have you believe you're just not cut out for the subject matter, but that's not always true. In the course Learning How to Learn from Coursera, you can understand what it takes to truly understand new information, as well as the key strategies and habits you can employ to make it all stick.

Learning How to Learn is taught by Dr. Barbara Oakley, a Ramón y Cajal Distinguished Scholar of Global Digital Learning at McMaster University, along with Dr. Terrence Sejnowski, who holds the Francis Crick Chair at the Salk Institute and is a professor at the University of California, San Diego. Throughout the weeks, they’ll teach you how to combat procrastination, how our brains process information, and the importance of breaking up new material into bite-sized chunks. You’ll also cover how taking breaks, getting sleep, and exercising are just as important as studying when it comes to learning something new.

According to Coursera, to finish the class in the typical four-week time, most students devote about three hours a week to the online videos, readings, quizzes, and coursework. There’s also no need to cram—which you’ll learn is not an effective learning tool—as this course is self-paced.

The course itself is free, but if you want a certificate of completion to share on your LinkedIn and resume, it will cost $49. Signing up for the certificate also gives you access to graded assignments, whereas the free version only allows you to read the course material.

You can also check out more free classes offered by Ivy League colleges by heading here.
