3 reasons why all the adults you know have started coloring again.

Have you seen adults coloring on the subway or in coffee shops? They might be on to something.

There's never been a better time to feel like a kid again.

For as long as there have been mortgages, taxes, jobs, and speeding tickets, there have been adults who wish they could turn back the clock to simpler times. That's nothing new.

But nostalgia has recently gone next-level.


If you want, you can now go away to adult summer camp, where you'll leave all technology at the entrance and enjoy four days of archery, tie-dye, and hiking. You can also spend a day at adult preschool, where you'll do arts and crafts, play games, and reconnect with your favorite childhood buddy: nap time.

Coloring books, though, are by far the most popular kids' activity for grown-ups. And it's not hard to see why.

Just imagine your favorite coloring book as a kid, only updated to reflect your much-improved motor skills and worldliness. Wouldn't it be nice to take an hour with a cup of coffee and get lost in a sea of possibility and imagination?

If you did, it might look something like this.

Beautiful, isn't it? So beautiful, in fact, that crotchety, jaded adults all over the world are dusting off their crayons and giving it a try.

These books are selling at breakneck pace. Publishers are even having trouble keeping them in stock.

The book that started the craze, "Secret Garden: An Inky Treasure Hunt and Coloring Book," has sold over 2 million copies worldwide since its release in 2013.

And there are many more like it burning up the bestseller lists.

"We've never seen a phenomenon like it in our thirty years of publishing. ... We just can't keep them in print fast enough," Lesley O'Mara, managing director of Michael O'Mara Books, told The New Yorker.

It doesn't look like this coloring book train is slowing down any time soon, so here are three reasons you need to get on board.

1. A good coloring session can relieve stress and anxiety.

There might be more to this whole coloring thing than just feeling like a kid.

Marti Faist, an art therapist, told the Baltimore Sun, "When someone is coloring, their mind and body are operating in a more integrated way. It's almost a meditative process."

"I've watched people under acute stress, almost panic-attack levels, color and have their blood pressure go down very quickly. It's cathartic for them."

And Marti's not the only one. Maybe you've heard of a guy named Carl Jung?

Jung was a big fan of art therapy, and he used coloring as a relaxation technique back in the early 1900s. He even believed that the colors his patients chose reflected an expression of deeper parts of their psyche. Jung himself actually used to draw and color mandalas, or spiritual geometric shapes, every morning. These same mandalas are the foundation of a lot of the most popular stress-relieving coloring books today.

2. No paper? No problem. Now, you can color on the go.

Now there's a brand new way to kill time on your smartphone. Photo and digital coloring skills by Heather Kumar/Twitter.

You know the rule: It's not an official craze unless it's integrated into social media. So, as appealing as drawing at your kitchen table for hours on end sounds, you can now color on your smartphone or tablet with just a few swipes of your finger, and you can easily tweet or Instagram your creations, too.

Colorfy, the most popular coloring app on the market, has been a huge hit with the mobile crowd, pulling in over 23,000 reviews on iTunes (it's also on Android).

A recent reviewer wrote: "This is a really great app. It lets me pass the time in a calming yet creative way."

But maybe the best thing about a coloring app is that it's easy to erase your design, start over, and create something completely different.

3) These coloring books are also hilarious.

Coloring isn't just about the beautifully elaborate sketches like those found in "Secret Garden" and its follow-up, " Enchanted Forest."

If you're more into some mindless fun, you might also enjoy coloring pictures of Ryan Gosling or iconic images from '90s pop culture!

And, if you're a real free spirit, you might enjoy a, um, truly "adult" coloring book.

Just a suggestion: might not want to pull this one out in public.

Whether you're coloring to relax or just to have some fun, there's a coloring book out there for you.

Coloring might become your favorite hobby ... again.

Putting your pet in cargo during a flight isn't always safe. In 2016, the Department of Transportation reported a total of 26 pet deaths and 22 injuries on flights. Because conditions in cargo can be uncomfortable for animals, the Humane Society recommends taking your pet aboard when you fly, or just leaving it at home.

It's not surprising that one Russian man didn't want to put his overweight cat in cargo during an eight-hour flight from Moscow to Vladivostok. What is surprising is the great lengths he took to fly with his four-legged friend.

Russian airline Aeroflot allows pets to fly inside the plane's cabin, as long as the cat weighs under 17.6 pounds and stays in its carrier during the flight. When Mikhail Galin went to check in, he was told he couldn't fly with his four-year old cat, Viktor. Viktor weighed in at 22 pounds and would have to be relegated to cargo.

But Viktor was sick from their earlier flight from Riga, Latvia to Moscow. And besides, Viktor had been allowed to fly inside the cabin during that flight. The airline staff didn't even bother to make Viktor sit on the scales. Galin was unable to persuade staff to bring his fur baby on board.

"To all attempts to explain that the cat won't survive there on an 8-hour flight with the baggage and would haunt her in her nightmares for the rest of her life, she (the Aeroflot staff member) replied that there are rules," Galin wrote in a Facebook post translated from Russian.

Newborn babies don't seem to do much beyond eating and pooping and, of course, hiccupping. A lot. Parenting advice on how to cure a baby's hiccups runs the whole gamut. It's recommended parents try everything from nursing to stop feeding the baby so much, from giving the baby gripe water to letting the hiccups play their course. But when your baby hiccups too much, you shouldn't freak out. There's a good reason why.

A new study published in Clinical Neurophysiology found that hiccups play an important role in a baby's development. Researchers from the University College London found 217 babies for their study, but only looked at 13 newborns with persistent hiccups. Ten of those babies hiccupped when they were awake, and three hiccupped during their "wriggly" sleep. We have no idea how the scientists got any work done with all that cuteness lying around.

Ask almost any woman about a time a man said or did something sexually inappropriate to them, and she'll have a story or four to tell. According to a survey NPR published last year, 81% of women report having experienced sexual harassment, with verbal harassment being the most common. (By contrast, 43% of men report being sexually harassed. Naturally harassment toward anyone of any sex or gender is not okay, but women have been putting up with this ish unchecked for centuries.)

One form of verbal sexual harassment is the all too common sexist or sexual "joke." Ha ha ha, I'm going to say something explicit or demeaning about you and then we can all laugh about how hilarious it is. And I'll probably get away with it because you'll be too embarrassed to say anything, and if you do you'll be accused of being overly sensitive. Ha! Won't that be a hoot?
