The simple 'Dorito theory' is a thoughtful way to break our addictive, unfulfilling habits

"Things that aren't actually satisfying are those that are maximally addictive."

Celeste Aria explains her "Dorito theory"

Philosopher Eric Hoffer once said, “You can’t get enough of what you truly don’t need to make you happy.” His point is that we can have enough of the things that truly satisfy us, such as a healthy relationship, necessary material possessions, or nutritious food.

However, the things that can’t satisfy us, such as junk food, toxic relationships, or status symbols, will always leave us feeling hollow, no matter how much we indulge.

This idea has popped back into public consciousness, although with a slight twist by TikTokker Celeste Aria, who refers to her version of the idea as the “Dorito theory.” “One thing I can’t stop thinking about is called the Dorito theory,” she said in a post with over 1 million views. “I learned about this, and now I see everything a little bit differently.”

Aria is a vintage fashion influencer and musician.

“When you eat a Dorito and finish your bite, you’re not fully satisfied,” Aria continues. “It’s not the same as eating a steak or eating a really satiating food that’s high in protein where after your bite, you really feel sort of that fullness and that warmth of satisfaction.”

Have you heard of Dorito Theory?

Have you heard of Dorito Theory? What types of things and experiences falls under it for you? #doritotheory #dopamine #addictivebehaviour #howtostoprotting #rottingtiktok #impulsivebehaviour #howtousetiktokless #howtoeathealthy #howtomotivateyourself #howtoimprove #thoughtexperiment #serotonin #mentalhealth #neuroscience #neurodivergent #adhd

“Eating potato chips is addictive because the peak of experience is kind of when you’re tasting it, and not after,” she continued. Put simply: "Experiences that aren't truly satisfying are maximally addictive."

The theory can even be applied to the platform where she went viral. TikTok may give us slight hits of joy (dopamine) as we scroll, but they can be few and far between. Eventually, when we put our phones down, the entire experience is little more than only a diversion. At worst, a waste of time and emotional energy.

The video received a lot of thoughtful responses on TikTok.

"In Gabor Maté's book ‘In the Realm of Hungry Ghosts, ’ he says 'You’ll never get enough of something that almost works,'" C. Badger wrote. "There’s a line in 'The Picture of Dorian Gray' that says something along the lines of 'I love a cigarette it leaves one so unsatisfied," and I think of it daily," Louis said, referring to Oscar Wilde's masterpiece.

"This is a unique TikTok video that is more like a steak than a Dorito. I feel I learned something and now I’m actually satisfied and don’t need to keep scrolling," Stevesapao added.

Dr. Jamie Sorenson says that the Dorito theory makes much sense from a psychiatric perspective. “Dorito theory is consistent with other addiction and behavioral theories,” she tells Fast Company. “The more immediate [the reward], the more likely we are to repeat that behavior, whether it’s eating Doritos, using a drug of choice, or scrolling on social media.”

The psychological underpinnings that drive people to overeat, engage in toxic relationships, or fall into the darkness of addiction are more complex than any idea that can be explained in a 90-second TikTok video. However, Dorito theory is a good test for whether we should indulge in certain vices, possessions, or people.

If you keep repeating a specific behavior repeatedly and it always leaves you feeling hollow, why not substitute it for something that is ultimately satisfying instead? Obviously, that’s easier said than done when you have a big bag of chips in your lap.

5 small things that made us smile this week

Your weekly cheat sheet to the best of the Internet

True


Life can be bleak, so we’re going to be celebrating the small joys while we can—whether that’s asweet snack that boosts your mood (courtesy of our friends atAll In), or a spontaneous moment between strangers that's so joyful it restores your faith in the algorithm (even if only for a second). These momentary mood boosters are everywhere you look—you just have to be able to find them underneath all the noise. And that’s where we come in.

Consider this weekly web series your cheat sheet to the best of the Internet—not just random memes to make you laugh, but examples of people truly finding something extraordinary in the mundane. Each Friday we'll be delivering five pieces of media that allow you to stop for a second, take a breath, and feel just a little bit brighter among the daily stress. (Think of us as your chronically online bestie who knows exactly how to make you smile, exactly when you need it the most.)

Ready to smile? Here we go.

1. The best travel buddy surprise 

@tarareynolds03

Surprising Grandson with going on vacation with him.

This sweet grandson thought he was just heading out on vacation—until he spotted a very familiar face at the airport. The moment he sees Grandma standing there, his jaw literally drops. He sets his backpack down and then runs straight into her arms for the biggest hug. "Oh my God! You're coming with us to Jamaica, right?!" he asks her, already smiling from ear to ear. It's the kind of unscripted joy that makes you want to call your own grandma to say hi—and other TikTokers are having all the feels in the comments section: "This brought me to tears," says user KE. "I would kill to go on another vacation with my grandma again. She passed in February. Take so many pictures!"

2. Saying 'thank you' to a very special teacher 

Last week, we shared a question on Upworthy’s Instagram that sparked an outpouring of heartfelt responses:
“If you could say thank you to one person right now, who would it be, and why?”

For Kate Delisle, a teacher in North Andover, Massachusetts, the answer came instantly: her longtime colleague and teaching assistant, Jeanne Donovan.

“Jeanne has been by my side for seventeen years,” Kate shared. “Next year, we’ll have to split our program — and we won’t be working together anymore.” In her message, Kate described Jeanne as more than just a coworker. She’s supportive, empathetic, and “my right arm — someone who lights up every room she enters. I’m privileged to know her and consider her family.”

To celebrate that incredible bond, our friends at All In recently paid a surprise visit to Kate and Jeanne at their school — letting Jeanne know just how deeply appreciated she is by her colleagues and students alike. And get this: Jeanne is *so* beloved that Kate's parents, kids, sister, and husband all came to the surprise to honor her alongside everyone else. A true tear-jerker and a must-watch.

3. The proudest big brother

Grab your tissues for this one. After eight long years of hoping for another baby, TikTok user Cayla Lee Brown surprises her stepson Caleb with a sonogram photo—and his reaction is nothing short of beautiful. When Caleb realizes not only that he's going to be a big brother but that twin siblings are on the way, his eyes well up and he whispers "We're having twins?!" Cue the heart explosion. In a follow-up video, Cayla shares something that makes this news extra special: Caleb isn't actually her biological child, and although she considers Caleb her son she wasn't sure she'd be able to have biological children at all. "[Caleb] was my gift and I was blessed with two more," she explains. This video is the best reminder that love makes a family, and sometimes the best surprises take a little time.

4. Overly excited dogs

This feel-good compilation is basically a highlight reel of dogs at their happiest: realizing they’re about to go on a walk. From excited tail wags to full-body zoomies, every pup in this video gives a masterclass in unfiltered enthusiasm. One especially clever owner even uses sign language to say “walk,” just to see if their dog picks up on it—and spoiler: the reaction is still pure chaos (the joyful kind). These dogs just know, and they are ready (read: unhinged.) Truly a reminder that the simplest things—in this case, some fresh air and a little adventure—are what spark the most joy.

Beavers were brought to the desert to save a dying river. 6 years later, here are the results.

Their engineering feats are pretty dam incredible.

Can outsider beavers save this dried up river?

It's not easy being a river in the desert under the best of circumstances. The ecosystem exists in a very delicate balance, allowing water sources to thrive in the harsh conditions. These water sources in otherwise extremely dry areas are vital to the survival of unique wildlife, agriculture, and even tourism as they provide fresh drinking water for the people who live nearby.

But man-made problems like climate change, over-farming, and pollution have made a tough job even tougher in some areas. Rivers in Utah and Colorado that are part of the Colorado River Basin have been barely surviving the extremely harsh drought season. When the riverbeds get too dry, fish and other aquatic creatures die off and the wildfire risk increases dramatically.

About six years ago, one team of researchers had a fascinating idea to restore the health of some of Utah's most vulnerable rivers: Bring in the beavers.

In 2019, master's student Emma Doden and a team of researchers from Utah State University began a "translocation" project to bring displaced beavers to areas like Utah's Price River, in the hopes of bringing it back to life.

Why beavers? It just makes dam sense! (Sorry.)

Beaver dams restrict the flow of water in some areas of a river, creating ponds and wetlands. In drought-stricken areas, fish and other wildlife can take refuge in the ponds while the rest of the river runs dry, thus riding out the danger until it rains again.

When beavers are present in a watershed, the benefits are unbelievable: Better water quality, healthier fish populations, better nutrient availability, and fewer or less severe wildfires.

It's why beavers have earned the title of "keystone species," or any animal that has a disproportionate impact on the ecosystem around them.

Doden and her team took beavers who were captured or removed from their original homes due to being a "nuisance," interfering with infrastructure, or being in danger, and—after a short period of quarantine—were brought to the Price River.

Despite the research team's best efforts, not all the translocated beavers have survived or stayed put over the years. Some have trouble adapting to their new home and die off or are killed by predators, while others leave of their own accord.

But enough have stayed and built dams since 2019 that the team is starting to see the results of the effort. In fact, beaver projects just like this one have been going on all over the state in recent years.

- YouTubewww.youtube.com

The water levels in the river are now the healthiest they've been in years. The fish are thriving. Residents of Utah are overjoyed at the results of the experiment.

A column in The Salt Lake Tribune from 2025 (six years after the beaver translocation began) writes that the revitalization of the Price River "helped save our Utah town."

"A tributary of the Colorado River, the Price River runs through downtown Helper. On a warm day, you’re likely to find the river filled with tourists and locals kayaking, tubing and fishing along its shore. A decade ago, it was hard to imagine this scene—and the thriving recreation economy that comes with it—was possible."

Of course, it wasn't JUST the beavers. Other federal water cleanup investments helped remove debris, break down old and malfunctioning dams, and place tighter regulations on agriculture grazing in the area that depleted vital plant life.

But the experts know that the beavers, and their incredible engineering work, are the real MVPs.

In other drying, struggling rivers in the area, researchers are bringing in beavers and even creating manmade beaver dams. They're hoping that the critters will take over the job as the rivers get healthier.

Utah's San Rafael river, which is in bleak condition, is a prime candidate. In on area of the river, a natural flood inspired a host of beavers to return to the area and "riparian habitat along that stretch had increased by 230%, and it had the most diverse flow patterns of anywhere on the river," according to KUER.

It's hard to believe that beavers nearly went extinct during the heyday of the fur trapping industry, and continued to struggle as they were considered nuisances and pests. Now, they're getting the respect they deserve as engineer marvels, and their populations have rebounded due to better PR and conservation programs.

To that I say...it's about dam time!

Why the viral advice to change your voicemail greeting if you're lost is absolutely a bad idea

Here's what to do instead.

Photo credit: Canva

A widespread myth about changing your voicemail greeting when stranded gets debunked by rescuers.

Back in 2021, multiple tragic news stories of people being stranded in the wilderness elicited a wave of viral posts sharing some wise-sounding advice for if you're ever stuck somewhere without cell service and a low battery.

The general suggestion was to your outgoing voicemail message to include your location. One version that went viral reads:

"If ever lost while hiking, stranded with a broken-down vehicle or other emergency situation, if your cell phone battery is low here is a tip that can very well save your life. Change your outgoing voicemail on your phone to a message that gives your approximate location, the time, the date, your situation; lost, out of gas, car broken down, injured, etc... plus any special instructions such as; 'You are staying with the car', 'You are walking towards a town' If your cell phone dies, stops working or loses signal your voicemail will still be working. Anyone calling your phone will hear your emergency instructions. They will know you need help and know where to find you or where to send help."

The problem is, the advice isn't wise after all. Yes, it sounds smart, but a Colorado rescue team explained why it's not.

The Alpine Rescue Team posted its response to the viral post on Facebook, writing:

"1. Without a signal (connection to the cell system) YOU CAN'T CHANGE YOUR VOICEMAIL. The voicemail system resides with your cell provider. To change your outgoing message, you have to CALL into your voicemail and then navigate the menus, record a new greeting, confirm the new greeting, etc. YOU CANNOT DO THIS WITH NO SIGNAL.

2. If your battery is low do not waste its power by calling your voice mail—or a friend or relative. Call 9-1-1 for help.

3. If you have no signal, text for help to 9-1-1. Many, if not most, 9-1-1 centers can receive a text.


4. Text takes much less power, is far more likely to get through, will automatically retry many times if you have spotty service, leaves record others can see and can give you an indication that it got thru. BTW, because of the automatic retries, you can compose and hit send on a text and then get your phone as high as possible to improve the chances of getting the message out.

5. Stay put. Okay, if you're lost or broken down and you've called for help (assuming you have signal and battery) please stay in one location—UNLESS YOU MUST MOVE FOR SAFETY REASONS. Changing your location makes our job more difficult. Trying to reach someone whose GPS location we have (within a circle, of course) is faster for us than trying to nail down a moving target. STAY PUT.

6. Maximize battery life. In order to make the battery last longer, turn off everything you do not need. Close all apps. Turn off WiFi and Bluetooth. Don't use your cell phone as a GPS/map device and especially do not use the compass if your phone has one -- the compass feature in some phones is a serious battery drain. Pull out your map and compass and/or use a dedicated GPS unit. You may be instructed, by text, to turn your phone off and text back at a specific time. Also, keep your phone just a little warm with some body heat or a handwarmer."

- YouTubewww.youtube.com

Many people probably think of their voicemail greeting as a recording saved on their phone, but it's not. A fact-check by USA Today, which consulted the top three carriers (Verizon, AT&T and T-Mobile), confirmed that cell service or a data connection is needed to change an outgoing voicemail message. You can do it over wi-fi, but that's not helpful if you're stranded on a mountain somewhere. You could change your voicemail greeting before you leave, letting people know where you're going to be adventuring if you feel comfortable with that, but once you're stuck without cell service, there's no changing it.

This is a friendly remind that it's always wise to look for what the actual experts say before passing along a viral social media post, even if the advice it contains sounds smart initially.

There's a reason why some people can perfectly copy accents, and others can't

Turns out, there's a neurodivergent link.

A woman in black long sleeve shirt stands in front of mirror.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.

It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."

Chameleon, science, reptile, adaptation, mirroringA chameleon rolls its eyes. Giphy SWR Kindernetz

Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."

While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."

People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'

They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."

(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)

Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."

Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"

@theweirdocoach

Anyone else? #adhdawareness #adhdinwomen #neurodivergent


Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."

And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."

Psychologist explains why everyone feels so exhausted these days and it makes a lot of sense

"A gentle reminder about why you are utterly exhausted…"

Photo by Jamie Street on Unsplash

It seems like most people are feeling wiped out these days. There's a reason for that.

We're more than four years past the onset of the COVID-19 pandemic, and it's been a weird ride, to say the least. These years have been hard, frustrating, confusing and tragic, and yet we keep on keeping on. Except the keeping on part isn't quite as simple as it sounds.

We've sort of collectively decided to move on, come what may. This year has been an experiment in normalcy, but one without a testable hypothesis or clear design. And it's taken a toll. So many people are feeling tired, exhausted, worn thin ("like butter scraped over too much bread," as Bilbo Baggins put it) these days.

But why?

Psychologist and speaker Naomi Holdt beautifully explained what's behind the overarching exhaustion people are feeling as we close out 2022, and it makes perfect sense. Holdt is a psychologist, author, and speaker with over two decades of experience, and specializes in the emotional well-being of children and young adults. She is also the author of "How to Raise Resilient Kids and Teens."

In a post on Facebook, she wrote:

"A gentle reminder about why you are utterly exhausted…

No one I know began this year on a full tank. Given the vicious onslaught of the previous two years (let’s just call it what it was) most of us dragged ourselves across the finish line of 2021… frazzled, spent, running on aged adrenaline fumes…

We crawled into 2022 still carrying shock, trauma, grief, heaviness, disbelief… The memories of a surreal existence…

And then it began… The fastest hurricane year we could ever have imagined. Whether we have consciously processed it or not, this has been a year of more pressure, more stress, and a race to 'catch up' in all departments… Every. Single. One. Work, school, sports, relationships, life…

Though not intentionally aware, perhaps hopeful that the busier we are, the more readily we will forget… the more easily we will undo the emotional tangle… the more permanently we will wipe away the scarring wounds…

We can’t.

And attempts to re-create some semblance of 'normal' on steroids while disregarding that for almost two years our sympathetic nervous systems were on full alert, has left our collective mental health in tatters. Our children and teens are not exempt. The natural byproduct of fighting a hurricane is complete and utter exhaustion…

So before you begin questioning the absolutely depleted and wrung-dry state you are in- Pause. Breathe. Remind yourself of who you are and what you have endured. And then remind yourself of what you have overcome.

Despite it all, you’re still going. (Even on the days you stumble and find yourself face down in a pile of dirt).


tired, exhausted, wicker chair, psychology, tired woman, A tired woman relaxing in a chair.via Canva/Photos

Understanding brings compassion… Most of the world’s citizens are in need of a little extra TLC at the moment. Most are donning invisible 'Handle with care' posters around their necks and 'Fragile' tattoos on their bodies…

Instead of racing to the finish line of this year, tread gently.

Go slowly. Amidst the chaos, find small pockets of silence. Find compassion. Allow the healing. And most of all… Be kind. There’s no human being on earth who couldn’t use just a little bit more of the healing salve of kindness."

Putting it like that, of course, we're exhausted. We're like a person who thinks they're feeling better at the end of an illness, so they dive fully back into life, only to crash midday because their body didn't actually have as much energy as their brain thought it did. We tried to fling ourselves into life, desperate to feel normal and make up for lost time, without taking the time to fully acknowledge the impact of the past two years or to fully recover and heal from it.


tired, exhausted, wicker chair, psychology, tired woman, A tired woman laying on the couch.via Canva/Photos

Of course, life can't just stop, but we do need to allow some time for our bodies, minds, and spirits to heal from what they've been through. The uncertainty, the precariousness of "normal," the after-effects of everything that upended life as we knew it are real. The grief and trauma of those who have experienced the worst of the pandemic are real. The overwhelm of our brains and hearts as we try to process it all is real.

So let's be gentle with one another and ourselves as we roll our harried selves into another new year. We could all use that little extra measure of grace as we strive to figure out what a true and healthy "normal" feels like.

Study discovers people don't age steadily, but in dramatic bursts at two specific ages

This explains SO much about your 40s.

Photo by Nati/Pexels

If you feel "old" practically overnight, there may be a good reason for that.

Aging is weird. You're trucking along, enjoying your middle-aged life, finally feeling like a real adult, when you look in the mirror one day and gasp. "Where did those wrinkles come from?" "Is that skin on my arm…crepey?!?" "Why am I aching like that?"

Somewhere in your mid-40s, you start noticing obvious signs of aging that seem to arrive overnight. You assumed it was a gradual process that you just hadn't noticed, but it sure as heck felt like it happened really fast.

New research indicates that may very well be the case. A 2024 study from researchers at Stanford tracked thousands of different molecules in people age 25 to 75 and found that people tend to make two big leaps in aging—one around age 44 and another around age 60. These findings indicate that aging can actually happen in bursts.

aging, age, old, growing up, growing old, 40s, 60sSimpsons Gify.yarn.co

“We’re not just changing gradually over time. There are some really dramatic changes,” said senior study author Michael Snyder, Ph.D., a geneticist and director of the Center for Genomics and Personalized Medicine at Stanford University. “It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that’s true no matter what class of molecules you look at.” The researchers assumed the mid-40s changes would be attributed to menopausal or perimenopausal changes in women influencing the overall numbers, but when they separated the results by sex they saw similar changes in men in their 40s.

"“This suggests that while menopause or perimenopause may contribute to the changes observed in women in their mid-40s, there are likely other, more significant factors influencing these changes in both men and women. Identifying and studying these factors should be a priority for future research,” said study author Xiaotao Shen, PhD, a former Stanford Medicine postdoctoral scholar who now teaches at Nanyang Technological University in Singapore.

The study included 108 participants who submitted blood and other samples every few months for several years. The scientists tracked age-related changes in 135,000 different molecules—nearly 250 billion distinct data points—to see how aging occurs.

The study may shed light on the reasons for jumps in certain diseases and maladies at certain ages. For the 40-somethings, scientists found significant changes in molecules related to alcohol, caffeine, and lipid metabolism, cardiovascular disease, and skin and muscle. For those in their 60s, changes related to carbohydrate and caffeine metabolism, immune regulation, kidney function, cardiovascular disease, and skin and muscle were found.

body, human body, anatomy, study, agingResearch shows the body goes through specific changes in our 40s and 60s.Canva Photos

The study authors did note that lifestyle might play a role in some of these changes. For instance, alcohol metabolism may be influenced by people drinking more heavily in their 40s, which tends to be a period of higher stress for many people. However, the researchers added that these bursts of aging in the mid-40s and early 60s indicate that people may want to pay closer attention to their health around those ages and make lifestyle changes that support greater overall health, such as increasing exercise or limiting alcohol.

The research team plans to study the drivers of these aging bursts to find out why they happen at these ages, but whatever the reasons, it's nice to know that the seemingly sudden onset of age-related woes isn't just in our imaginations.

It's understandable that we worry about aging, as physical signs of aging remind us of our own mortality. We also have all kinds of social messaging that tells us youth is ideal and beautiful and old is bad and ugly, so of course we give aging the side-eye. But none of us can avoid aging altogether, so the more positive and healthy we are in our approach to aging, the better off we'll be, no matter when and to what degree aging hits us.
