What People Are Getting Wrong This Week: What Are 'Grabavoi Numbers'?

Nothing is really new in conspiracy theories, but the churning morass of social media sometimes mixes up new combinations of old nonsense that bubbles up to the surface unexpectedly. Lately, interest in "Grabovoi codes" or "Grabovoi numbers" is high. The CIA is supposedly hiding Grabovoi codes, strings of numbers that one can concentrate upon in order to cure disease, get rich, and manifest a new car. This video, for instance, has been viewed over a million times in the last couple weeks:

"You can search 'quantum healing codes' at the CIA.gov website and it has many different codes for many different things," This TikToker says, "for instance you would think of the part of your body that's hurting and repeat 55515 and, voila, pain starts to vanish," they add. Many TikTokers are into this. There are over 43,000 posts on the "Grabovoi" hashtag.

It might seem like lightweight wish fulfillment, but I looked into where belief in the Grabovoi codes comes from, and it's way deeper than TikTok. The online world's belief in magic numbers is a case of historical telephone that can be traced to a convicted Russian conman, an American broadcasting tycoon who believed he could travel outside of his body, and the strange history of the CIA and KGB's research into the paranormal—it gets real weird, real quick. But first, do the Grabovoi codes actually work?

Can you use Grabovoi codes to cure pain and disease and/or manifest wealth?

No. But sometimes, kind of yes. There is a library of research about the connection between the cognitive mind and the perception of pain, and scientific research supports the general idea that if you are experiencing mild pain, concentrating on something else, like a specific number, could reduce the perception of that pain. But the number itself is irrelevant; it's the distraction that matters. All other claims about benefits from these numbers—that they represent frequencies connected to specific real life outcomes, that they can help you find love, etc.— are not supported by any evidence.

Do Grabovoi codes come from the CIA?

No. But kind of yes. Despite the claims of online believers, searching "quantum healing codes," or "Grabovoi" in the CIA's declassified files database does not result in a list of healing numbers. There is no mention of the inventor of the Grabovoi numbers, Grigori Grabovoi, in the files either. There is actually one "healing number" contained in declassified CIA files. But first...

Who is Grigori Grabovoi?

Grabovoi is the founder of the Russian group Teaching Universal Salvation and Harmonious Development. He claims he is the second coming of Jesus, can cure cancer, can teleport, and can repair anything, mechanical or electronic, remotely. In 2008, Grabovoi was sentenced to 11 years in a Russian prison for fraud after accepting payment to resurrect children slain in the Beslan school siege. He's served his sentence and lives in Serbia now.

Among the hundreds of books (usually transcripts of lectures) Grabovoi has authored is Restoration of Matter of Human Being by Concentrating on Number Sequence, which lays out some of the Grabovoi numbers. Not all of them, though. Grabovoi tends to publish books of numbers for specific subjects, like Concentration on Numerical Sequences to Reset the Body of Cats. Grabovoi doesn't miss a trick.

Which brings us to TikTok. Beginning around 2016, Grabovoi and his believers/followers started promoting his numbers and theories on Pinterest, TikTok, YouTube, and basically everywhere else, and they were spread by people connected with hashtags like #manifestation, particularly when Covid19 was at its peak. So that's why everyone is talking about Grabovoi codes, but it doesn't explain the CIA connection. That's because of Robert Monroe.

Who is Robert Monroe?

Robert Allan Monroe was a media tycoon who made a ton of money producing radio shows in the 1930s and 40s. By the late 1950s, Monroe owned a network of radio stations and early cable TV channels across Virginia. In 1958, this rich radio dude claimed he had a spontaneous out-of-body experience after listening to binaural sounds.

To study the phenomena, Monroe used his considerable wealth to found the Monroe Institute. In 1977 the Institute published the The Gateway Intermediate Workbook, a collection of mental exercises and visualization tools designed to help people relax and/or project their consciousness across time and space. It advised people in pain to close their eyes and repeat "55515" to dull pain signals. Why this number specifically is not explained, but Monroe's whole thing was "hemi-sync" audio signals, aka "binaural beats," so the idea may have been that repeating a precise rhythmic sequence like "five-five-five-one-five" would echo pulsing audio frequencies. It's hard to say. Anyway, repeating this series of numbers is unlikely to have any more effect on pain than repeating anything else, and the research on binaural beats isn't promising. None of this changes the fact that the CIA had a real connection to the Monroe Institute.

How the CIA connected to the Monroe Institute

The Monroe Institute's workbook and other esoteric material were part of the CIA's reading room, and by the late 1970s and into the early 1980s, the U.S. Army and the CIA routinely sent high level intelligence officers to the Monroe Institute's campus, especially in connection with Project Stargate, the military's effort to create psychic soldiers and/or remote viewers who could project their consciousness anywhere they wanted.

The "CIA connection" is the most compelling thing about TikTok's interest in magic numbers. The CIA and army intelligence are thought of as serious, smart people who deal in information the rest of us are not privy to. If they believe in magic numbers, it must be true, right? Well, yes and no. The CIA/military is a group of people, and all groups of people (even smart ones) can be bamboozled.

Cold war paranoia leads to esoteric research

Consider the atomic bomb from a military, non-scientist perspective: If a split atom can level a city, is it that strange to believe the human mind has capacities we don't understand? Add to that the revelation that the USSR was conducting its own paranormal research, and you have a perfect storm. If we're wrong about this, the thinking that led to military paranormal research likely went, and the Soviets make atomic-bomb-level breakthroughs in the field of parapsychology, they'll bury us without firing a shot; it would be crazy to not look into it. And given the massive military budgets of the time, it was a tiny expenditure with a potentially nuclear-level outcome. (There's also the possibility that both the CIA and the KGB were purposefully deceiving one another about the extent of their research to make the other spend more. Things get shadowy during the Cold War.)

Enter the Monroe Institute. Robert Allan Monroe wasn't a wild-eyed hippie. He wore expensive suits and had straight white teeth. At least on the surface, the Monroe Institute was taking a corporate approach to the mind/body connection. Its approach was structured, serious, and deliberately clinical. The Gateway Workbook is a step-by-step process instead of a leap of faith. The Monroe Institute was the kind of place the military might feel confident sending its men.

The reality check of the 1990s

Research into remote viewing and other esoterica went on, seemingly with no tangible results. In 1989, Soviet Union collapsed without the help of psychic warriors or atomic bombs, and the CIA took a hard look at its paranormal programs in the mid 1990s. 1995's report "An Evaluation of Remote Viewing: Research and Applications," concludes, "OK, this was dumb and it never worked and we should stop throwing money at it." I mean, that's the gist. Anyway, the material was declassified so we could all take a look at how our taxes are spent.

Which brings us back to TikTok. Everything the CIA releases has always been pored over by curious people, where it marinates with other "official" weirdness like UFO research and quantum mechanics until it gets spit back in altered form. The no-context architecture of social media seems designed to legitimize fringe ideas. A convicted Russian conman's magic numbers collide with a wealthy eccentric's out-of-body workbook that got filed in a CIA reading room, and suddenly a million people think the CIA has a secret cure for back pain.

The low cost of entry of the Grabovoi codes

I don't think too many people on TikTok really believe that they can manifest magic and get rid of pain by repeating a number, but like a paranoid military throwing a few million at psychic research in the remote hopes of a Cold War-winning breakthrough, the barrier to entry is low. When you're in pain or you're broke or you're scared, why not repeat some numbers to yourself? It can't hurt.

But it won't help that much, either. Research shows that cognitively demanding tasks like puzzles or math problems are more effective ways to distract yourself from pain than repeating a number, and while learning about out-of-body experiences from the Monroe Institute (which is still around, by the way) might be interesting, there are better ways to relax and clear your mind. For instance, rather than spending $2,895.00 to sit around in a dark room in Virginia envisioning a tropical beach at the Institute's five-day "Gateway Voyage," book a trip to Bali. For the same price, you could actually be on a tropical beach, and stay at a luxury villa with a private plunge pool and a personal butler.



These Noise-Cancelling Soundcore Earbuds Are 31% Off Right Now

Spending less than $100 on noise-canceling earbuds used to mean accepting weak ANC, short battery life, or stripped-down features. The Anker Soundcore Liberty 5 makes fewer of those compromises. They’re currently $89.98 on Amazon, down from $129.99—a $40 drop, or 31% off—and price trackers show this is the lowest they’ve been.

PCMag gave them an “excellent” rating and named them the “Best Budget Earphones” of 2025, mainly because they offer features that are usually reserved for pricier models. The Liberty 5 earbuds have a glossy finish, while their charging case has a matte texture and slide-open top. The fit is secure enough for long listening sessions without feeling tight. They connect over Bluetooth and support AAC, SBC, and LDAC codecs (LDAC can deliver higher-quality audio on supported Android devices), which is notable at this price.

You also get Bluetooth multipoint (which lets you connect to two devices at once), so you can switch between a laptop and a phone without re-pairing. Controls are handled by squeezing the stem. A single squeeze plays or pauses audio. A long squeeze switches between noise cancellation and transparency mode. You can customize most gestures in the Soundcore app, including EQ adjustments to fine-tune the sound.

Noise cancellation is where these earbuds stand out for the price. They block low-frequency rumble from planes and engines effectively, and they reduce much of the chatter in a café. They are not on the same level as top-tier models from Apple or Bose, but they perform better than many earbuds in this range, notes this PCMag review.

Battery life is strong. With ANC on, you get up to eight hours per charge and up to 32 hours with the case. Turn ANC off and that jumps to 12 hours and 48 hours total. A 10-minute charge gives you about five hours of playback, and the case supports wireless charging. With IP55 water resistance for sweat and rain, the Liberty 5 is a practical pick for workouts, commuting, or travel at a record-low price.

You Can Choose New 'Thinking Levels' for Gemini

by

You need to use a lot of quotation when discussing AI. There's "intelligence," of course, but also "thinking," which these days usually refers to a specific type of model that breaks requests into multiple steps and takes longer to process (or "think through") them. Thinking models are nothing new, but if you use Gemini, you do have new thinking "levels" to choose from when using non-thinking models. Here's how it works.

As spotted by 9to5Google, there's a new "Thinking level" option at the bottom of the model selector in Google's Gemini app for iOS and Android. To be clear, this isn't the "Thinking" model listed under "Gemini 3," as this model has been available for some time. Instead, "Thinking level" appears when using either Fast (which uses Gemini 3 Flash), or Gemini 3.1 Pro, when you aren't using Thinking. When "Thinking level" does show up on your end, you'll see two options: "Standard" and "Extended." Google says that Standard is best for most problems, while Extended offers more time for "complex topics."

It seems that Google is giving users more processing options when using non-thinking models in Gemini. If you're using the Fast option, for example, you might not get the answer (or the quality of answer) you're looking for, since the model is designed to produce a response as quickly as possible. Therefore, you may want to dive into the Thinking level menu to switch to Extended: It may take a bit longer than usual, but you may boost your chance of getting the response you're expecting—all without having to use the actual Thinking model, which may take too long altogether.

Per 9to5Google's coverage, this doesn't appear to be exclusive to Google AI Plus subscribers. In the outlet's screenshots showing the feature, there's still an option to upgrade to the subscription plan, so free users should see "Thinking level" rolling out on their end. (As of this article, I don't see it yet.)

These changes come on the eve of Google I/O, where Google will undoubtedly announce many new Gemini features and AI updates in general. Last week, the company hosted The Android Show: I/O Edition, which ran through a number of Android announcements ahead of I/O. This was the second year in a row Google decided to break out Android news into its own segment, likely because it wants to dedicate so much of I/O to AI.



This Waterproof Bluetooth Sony Speaker Is 34% Off Right Now

by

We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.

Sony’s SRS-XB100 is down to $43 from its usual $64.99. This is Sony’s entry-level portable Bluetooth speaker, and it shows in both good and limiting ways. It’s small, light, and built for casual use. At under 10 ounces and roughly the size of a coffee mug, it fits easily in a bag or clips onto a backpack with its included strap. The matte black finish keeps things simple, and the IP67 rating means it’s fully dust proof and can withstand submersion in water for up to 30 minutes. It’s a speaker you can bring to the pool, the shower, or a dusty worksite without worrying about damage.

The sound is better than you might expect from something this size. The upward-firing 2W driver and passive bass radiator add some punch to tracks with drum-heavy mixes, though it can’t reach true sub-bass depth. At higher volumes, the speaker relies on digital processing to prevent distortion, which slightly reduces bass impact, notes this PCMag review. Vocals come through clearly, though, making it suitable for podcasts and calls, and the built-in speakerphone mic is a real advantage here—it’s noticeably clearer than what you get from many small speakers.

Battery life is solid, with up to 16 hours at moderate volume, though that drops to around five hours if you push it to max. On the downside, there’s no companion app, so you can’t adjust the sound or get updates later. You are also stuck with mono audio unless you buy a second unit and pair them for stereo sound–on its own, the SRS-XB100 is still a mono speaker with a limited soundstage. And while its Bluetooth 5.3 support is solid (and it works with AAC and SBC codecs), there’s no wifi connectivity or multi-room support.

What to Look For When You're Buying Refurbished Tech (and the Best Sites to Check Out)

by

With AI infrastructure demands continuing to push up memory prices, it's tough to find good value for your tech purchases right now—though the Lifehacker team is always trying its best to help out—and buying used or refurbished can save you a substantial amount of money.

That's the big advantage, but there are downsides: You're not getting a brand new device, which means it might not look pristine, and it could come with issues or technical faults attached. The SSD inside a two-year-old laptop won't be quite as speedy as one inside a new model, for example.

It's something of a gamble, then, but you can make sure the odds are in your favor by knowing where to buy from and what to look for—and there are definitely used and refurbished items out there that are close to perfect in terms of looks and performance, so you're getting big savings without any real trade-offs.

For the purposes of this article, "refurbished" means a device that's been returned to the manufacturer for some reason, and then checked and cleared for resale, typically with a limited warranty attached. If something is "used," it usually comes from a private seller, with fewer guarantees about future performance.

Why go used or refurbished?

Used or refurbished isn't the route everyone should go down, and if you've got the budget, then buying new is probably best: You get an untouched, factory-fresh device, and plenty of cover if something is wrong with it (which will depend on what type of gadget it is and where you bought it from). With refurbished items, though, sometimes an item will have been returned just because it was opened or the box was damaged, or it was on display in a store—you're essentially getting something that's almost as good as brand new, for a lot less.

Opting for a used device means you can save even more, but the risks are greater—each deal is different, but you're looking at everything from 10-year-old phones that people are about to throw away to nearly new laptops that were unwanted gifts. The range in terms of quality and reliability is a lot greater here.

The big reason to go used or refurbished is the amount of money you can save, especially if you're not particularly worried about getting something in perfect condition, and extra especially if you know a lot about the particular type of tech you're buying—which means you should be able to spot great deals better than most, and can do a few upgrades or repairs of your own once you've got your device.

There's also the environmental angle: You're picking up a device that might otherwise get thrown away, extending its lifespan and reducing e-waste. A lot of energy and resources go into manufacturing new devices, so if you're buying used or refurbished on a regular basis, you're contributing less to that.

Bear in mind that a lot of other people are saving money this way too, and the competition can be fierce when it comes to grabbing the best deals (there will also be those out there who are buying tech, repairing or polishing it, and selling it). Deciding to do this can be more stressful or more fun, depending on your perspective.

What to watch out for when you're buying used tech

First and foremost, look who you're buying from, and adjust your skepticism accordingly. There are refurbished items from big name manufacturers sold through official stores at one end of the spectrum, and used gadgets from someone you've never heard of, with zero seller ratings, at the other.

That's not to say you can't pick up a great bargain from a person with no selling history on a personal marketplace—but there's much more of a risk of being ripped off in these scenarios. If you are buying from an individual, look at feedback left from other buyers, if there are any, and factor this into your buying decision.

When it comes to refurbished items, look carefully at the device's ratings in terms of performance and damage, any warranty that's being offered with the gadget, and what the returns policy is. Check what accessories (like a charger) are included, as otherwise you'll need to buy these separately.

For used gadgets, try and get as much information as you can from the item listing. Ideally, you want to see a lot of pictures (from various angles) and a detailed specs list, but if there isn't enough, don't be afraid to ask: It's particularly important to check on battery health and capacity, as this is one of the areas where older tech can be problematic.

Always check the age of a device, too. Software updates are only issued for so long (usually around seven years for phones for example), and you don't want to end up with something that's immediately outdated. The always-helpful End of Life website can tell you when a lot of popular gadgets are going to become obsolete.

The more expensive the device you're shopping for, the more careful you need to be: Not only do you stand to lose more money, you'll come across more scammers. And speaking of price, check the current prices for the new version of whatever it is you're buying, too—on some devices, the savings might not be worth it.

The best places to buy used and refurbished tech

eBay has its pros and its cons, but it remains one of the best places to pick up used tech, as long as you do it carefully. The platform runs the full gamut from official retailers to individuals, so there's a lot here to pick through, thd there are some great deals to be had. Look for items with the eBay Money Back Guarantee offered.

Back Market site

Back Market has long been a trusted outlet for refurbishers, and it takes a lot of the stress and hassle out of buying refurbed tech. The site works a lot like a regular retail store, and you can quickly get information on the condition each item is in, and how it's been checked and restored. There are lots of user reviews to look through as well.

Swappa is a bit of a mix of eBay and Back Market. It's mostly third-party resellers who do business here, though there are individual sellers too. All listings are reviewed by Swappa staff and are clearly categorized, and you can see at a glance a number of key details: the specs, the condition, and (sometimes) a limited warranty.

Gazelle is exclusively for phones and tablets, and prides itself on its simplicity and ease of use. It offers its own in-house certification process for refurbished items, so you're buying gadgets that have been returned or traded in directly. There's a 30-day return window, plus plenty of information on each item, including cosmetic condition.

Amazon Renewed is worth a look if you're prioritizing convenience and safety: The shopping experience is integrated right into the Amazon website, and everything comes with a 90-day guarantee window for returning items. The quality on offer can vary, so check listings carefully, in terms of item condition and bundled accessories.

Then you've got the official refurbished outlets, including Apple, Samsung, and Dell. These score highly on reliability and trustworthiness, though the savings are likely to be less significant. You get less information on individual items as everything is done in bulk, but the guarantees and warranties are excellent—in the case of Apple, for example, you get a one-year limited warranty.



This Eufy Security Four-Camera Kit Is 43% Off Right Now

by

We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.

At $199.96 for the four-camera kit, down from $349.99, the Eufy Security EufyCam C35 bundle is currently at its lowest price yet, according to price trackers. Eufy’s biggest advantage remains local storage—the included HomeBase Mini stores footage locally with 8GB of built-in storage, and both the hub and cameras support microSD cards if you need more room. You can still pay for cloud storage if you want (starting at $3.99/mo for a single camera or $13.99/mo for 10 devices), but unlike many competing systems, you are not forced into it just to access recordings. That alone makes this setup appealing for anyone tired of stacking subscriptions on top of hardware purchases.

Setup is largely painless. You install the Eufy app, scan a few QR codes, and the HomeBase Mini handles the rest of the pairing process for all four cameras—you don’t have to re-enter wifi credentials for every device, which saves time when mounting multiple cameras around the house. The cameras themselves cover most of the features people expect from a modern wireless security system—they run on batteries, support two-way audio, and have IP67 weather resistance for outdoor use, notes this CNET review. Eufy also includes color night vision, motion alerts, activity zones, and built-in deterrents like lights and sirens. You can tweak motion sensitivity, limit recording lengths to preserve battery life, and filter alerts using AI detection via the companion app.

That said, the EufyCam C35 records at 1080p, which now feels modest compared to the growing number of 2K and 4K security cameras available on the market. While the footage is usable and clear enough to identify activity around a yard, garage, or living room, finer details can look soft or grainy, especially at night, and faces and objects become less defined at longer distances. None of this makes the system unusable, but buyers expecting razor-sharp footage may want to spend more on a higher-resolution system like the EufyCam S4. Still, for under $200, this kit gives you four weatherproof cameras, local storage, solid battery life, and a polished app experience without locking core features behind a subscription.




What Is Functional Fitness, Anyway?

by

Over the past few decades, “functional” fitness has been seen as everything from a niche practice, to a trend, to a joke. The styles of training that call themselves “functional” vary as well, from bodyweight exercises to Hyrox training. So what is functional fitness really?

Functional fitness is more a buzzword than a style of training

If you ask somebody who coaches functional fitness, they’ll probably tell you that it’s about doing exercises that will help you in everyday life. Maybe that means doing farmer’s walks with heavy dumbbells so that you’ll be strong enough to carry all the groceries in one trip. Maybe it’s doing hundreds of air squats so you can bend down to pick up your kids. Maybe it’s balancing on a Bosu so you’ll be less likely to slip and fall on an icy sidewalk.

Historian Conor Heffernan traces the roots of functional fitness to exercises that were prescribed for general health rather than specifically for strength or sports. Sometimes these would use unusual apparatus like pulleys and weighted balls or, today, battle ropes or suspension trainers.

Today’s trainers often define functional fitness in opposition to what they think “regular” fitness is. For some, regular training means a lot of single-joint exercises like bicep curls, so they’ll program compound movements that involve the whole body. For others, regular training means you’re using heavy weights, so they consider functional training to be workouts that use light weights or only bodyweight. And for still others, regular training means doing sets and resting in between them, while functional training keeps you moving the whole time. In other words, “functional” can mean any type of exercise that your trainer prefers.

Sometimes "functional fitness" is like a code word

Just when it looked like the functional fitness craze was dying down, it seems more and more gyms and trainers are picking the term back up. But this time, I think something specific is going on: “Functional” is code for “CrossFit-type exercise, but not the CrossFit brand.”

CrossFit is a mix of barbell training, gymnastics and calisthenics moves, and cardio. Workouts may involve skill practice, strength training, and most famously timed “WODs” (workouts of the day) that require cardio fitness to power through. But the name CrossFit is trademarked, and it’s tied to a specific company, and that company has some unpleasant things in its history. What do you do if you like the style of workout but you don’t want to do CrossFit CrossFit? You call it something else.

So when people do similar exercises as what you'd see in a CrossFit class, sometimes that gets called functional, whether it's being done for a real-life purpose or not. For example, Hyrox classes prepare you for a race, which isn't really functional; but you'll be doing wall balls and lunges and pushing a sled, which you could argue are functional exercises

No exercise is non-functional

The idea of training to be better at everyday life is not a bad one. We all need strength and mobility to exist as a human being without complaining about our knees and our backs all the time, and that goes double as we age.

But do you need a specific type of exercise to do that? Not really. Plain old boring barbell squats might not be “functional” in some people’s eyes, but they still build a ton of leg strength to help you pick up your kids. Anything that improves some aspect of your fitness is going to be helpful to you in everyday life.

If you want to take a lesson from the world of functional fitness, let it be that you’re not limited to any stereotype of fitness. Balance training can be fun and helpful; so can grip training, and core training, and interval cardio training, and all kinds of things you might not normally think to do in the gym. Learning new skills is an exercise for your brain, as well as your body, and it’s a worthwhile one, too—even if you’ll never find a “functional” use for something like handstand pushups.
