We have believed all our lives that “dying of grief” was a romantic myth. Science is clear that there is some truth

The classic scene of two old people who have been together their entire lives, and when one dies, the other follows him a few days later because “he couldn’t bear the pain” seems to be something that remains in the movies. However, what we have always dismissed as romantic hyperbole or statistical coincidence has, in reality, deep physiological support. It is studied. A recent deluge of scientific data puts on the table a conclusion that is quite devastating by pointing out that intense grief not only hurts emotionally, but also drastically increases the chances of suffering a fatal cardiovascular event that triggers long-term mortality. The most robust and recent confirmation comes through a study published in Frontiers in Public Health that analyzed 1735 people in a ground situation to be able to find out what happened in the long term with those who could not overcome a loss naturally. The results. The researchers here divided the patients into groups according to the intensity and duration of their suffering. What was precisely seen is that those who showed a high and sustained grief trajectory, which is called prolonged grief, not only needed many medical consultations and psychotropic drugs, but also presented a higher risk of mortality than the low grief groups. Translated into plain numbers: people trapped in persistent grief were almost twice as likely to die in the decade after the loss. The heart breaks. When we receive bad news, we sometimes say that the heart ‘has broken’ and for many it may seem strange, since physically the heart is intact. But this expression, which may be popular, has clinical demonstration behind it, as pointed out a published study in Circulation which shows that the first weeks after widowhood or the loss of a loved one are high risk. Specifically, in the first 24 hours after the loss, it was shown that the risk of suffering an acute myocardial infarction reached its maximum peakwhile in the following 30 days cardiovascular events also increased, including stroke. In the guides. As a curiosity, there is even a clinically documented pathology known as Takotsubo syndrome (or broken heart syndrome), which is a cardiomyopathy induced by extreme emotional stress that temporarily weakens the heart muscle, simulating the symptoms of a massive heart attack. The small print. What has been compiled in this case is a statistical correlation, that is, that those people who have had a deep mourning have seen their mortality increase. But this does not mean that there will be an event of this magnitude. What happens in these cases is that grief is a marker of constant vulnerability, since cortisol levels increase, keeping the body in a state of alert that exhausts the immune system. But in addition, those who suffer extreme grief often stop eating properly and reduce their physical activity to zero, and in many cases, forget to take their medication. All of this ultimately increases the risk of mortality, but not the loss itself.

What is it, what is it for, who can use it and how to activate it

Let’s explain to you what is lock mode of ChatGPTa method with which you can have more protection against attacks aimed at the artificial intelligence. To do so, it will greatly limit what AI can do, but in exchange it will be more difficult for it to send data abroad. We are going to start by explaining what this mode is and what it is for, so that you can understand its usefulness. Then we will explain who will be able to use it, and we will finish by explaining the steps to activate it in case you are within that group of users. What is ChatGPT Lock Mode ChatGPT’s Lockdown Mode is used to Protect organizations from prompt injection and other types of attacks that could compromise sensitive data of its members. Prompt injection is when you put a hidden instruction inside a file or a website so that, when an AI reads it, it behaves in a certain way without the user knowing. And this can be quite dangerous in some contexts. Imagine that you are part of an organization or company where you review contracts, analyze customer data, or work with confidential company information using artificial intelligence. So, by using ChatGPT you expose yourself to the fact that a document, an external app or a website have a hidden instruction to execute commands that send this data to an attacker. And that’s where this mode comes into play. To protect you, when you activate ChatGPT will very strictly limit AI. With these limitations it will be much less useful, but also safer to use when handling sensitive data. What it does and what it is for Lock Mode will limit ChatGPT’s interaction with the outside world. It will be like a barrier that does not allow you to consult apps and pages, in order to minimize the possibilities of attacks and data leaks when you work with extremely sensitive information. The premise is simple: if ChatGPT can’t send data outyou won’t be able to filter them even if someone tries to trick you. It assumes that an attacker could trick the model, and focuses on preventing this trick from resulting in the leak of sensitive data. This mode does not eliminate prompt injectionsbut rather the channels through which these injections can cause you to send data to an attacker. For example, ChatGPT will continue reading in a PDF the hidden order to send your clients’ personal data to a certain address. However, without access to external pages, you simply will not be able to comply with that order. Lockdown Mode disables six key capabilities of artificial intelligence. They are the following: Web browsing with live web access: ChatGPT will only be able to access cached content on the web. This makes search results outdated and limited, but also prevents data from being transmitted to an attacker. Image Support: ChatGPT responses may not include images. Advanced research: This function is disabled. Agent mode: This feature is also disabled so that ChatGPT cannot take actions on your behalf. Canvas networks: Users cannot approve code generated in canvas to access the Internet. File download: ChatGPT will not be able to download files for analysis. If you upload a file you will be able to work on it manually, but you will not be able to download them from the internet. ChatGPT will answer your questions and help you with the text based on the knowledge it has been trained with, but you will no longer be able to connect to the internet or interact with external systems while you have this mode activated. One thing you should be careful with is that applications can interact with the Internet when you activate this mode, including MCPs and connectors. This poses an added risk that you must take into account if you link these elements. Who can use Lock Mode From June 2026 Any user can use Lock Mode. It was initially aimed only at users of ChatGPT Enterprise, Edu, ChatGPT for Healthcare and ChatGPT for Teachers, but now anyone can use it. How to activate ChatGPT Lock Mode To activate ChatGPT blocking mode you have to enter its settings on the web or mobile app. Once inside go to the section Securityand in it activate the option Lock mode that appears in the section Advanced security. This will open a window informing you of all the things you will no longer be able to do when you activate it. On this screen, simply press the button Activate to confirm the action.

Russia is the great missing person in the AI ​​race. He has neither chips nor talent, and his great ally only gives him the leftovers

What’s happening with AI in Russia? The artificial intelligence race has as absolute protagonists to the US and China, and it’s surprising that a power like Russia does not seem to be advancing in this type of field. The truth is that he is doing it, but his situation in this area is worrying. Russia does have AI models. Although they are hardly talked about, there are several AI models that are developed by Russian companies and that, above all, are totally oriented towards their citizens. The country does not have access to Western models such as ChatGPT or Claude, but it does have access to these alternatives: GigaChat: is probably the most advanced Russian model. It is developed by the financial institution Sberbank, and It is available via web although to use it it is necessary to have an account in said entity. Yandex Alice: the company that has already offered a search engine in the image and likeness of Google for years also has its own artificial intelligence model, called Alice AI. It is possible to use from its official website in both English and Russian (Spanish is not supported) like a traditional chatbot. MTS AI – one of the largest telecom operators in Russia also has its own model, MTS AImore aimed at companies and developers with its Cotype models that recently support the ability to create agents for enterprise applications. behind. The veto of chips and advanced technology from the US has been one of the factors that has caused these models to be clearly behind the latest frontier models from companies such as OpenAI or Anthropic. He proves it launched three months ago from GigaChat-3.1-Ultra-702B, an open weights model derived from DeepSeek 702B A36B. In the published benchmarks, the performance of this model is at the level of DeepSeek v3 (launched in December 2024) or Qwen3-235B (launched in April 2025). This model is for example available at Hugging Face. China is your natural ally. China and Russia have long maintained a geopolitical alliance that has an impact in various areas. The curious thing is that in this case that impact is being felt less than one would expect. Russian AI models are based on Chinese open models, but at the moment it seems that These are somewhat old versions which they later adapt to Russian. And as happens with Chinese models, which censor certain topics, Russian models apply that same filtering to avoid sensitive issues. Without chips there is no AI. The big problem Russia faces is the same one China faces, but amplified. They don’t have access to advanced Nvidia chips to train their models, so they have looked Shortcuts to bypass trade restrictions and be able to develop those models. Russia, get in line. Sberbank, for example, is trying to get access to Chinese AI chips like the Huawei Ascend 950 for your projects, but there are two problems here. The first is that these chips are aimed at model inference, not their training. The second, that at the moment those who have priority access to these chips are the Chinese companies themselves, which are reserving large quantities for their future projects. ByteDance, Tencent or Alibaba have placed important orders that leave Russia in a complicated situation. Russian chips in the (distant) future. These problems of access to specialized chips could be solved if Russia manages to boost its semiconductor industry. Baikal Electronics has been working on alternatives to x86 chips from Intel and AMD for some time, but also promise develop AI chips in 2029 or 2030. Once again, commercial and technological vetoes mean that in both scenarios the company’s proposals cannot compete with the latest advances of its Western competitors, at least for now. Industrial and military use. Russian LLM developments not only try to present an option for Russian citizens, but also for military applications. The war with Ukraine has actually revealed how Russia is using the well-known AI miniPCs Nvidia Jetson for its Shahed missiles. Russia has it very difficult. The current situation in Russia makes it difficult for the country to present notable alternatives to the most advanced AI models of the US or China (or even Europe). The war with Ukraine also caused an exodus of talent and Russian engineers, although companies like Sber have tried to boost campaigns to attract talent in the university environment. All of this adds to Russia’s difficult access to the most advanced hardware and software and its dependence on an ally like China that is prioritizing its own AI companies.

Ukraine has turned military bridges into impossible targets. Russia just responded with a Frankenstein on wheels

In World War II, six soldiers could carry parts by hand of a Bailey bridge and build a passage for tanks in a matter of hours. Eight decades later, the real challenge is no longer building the bridge: it is making it survive long enough to enter service. River crossings are a nightmare. Crossing a river has always been one of the most delicate operations for any army. Crossing points are predictable, vehicles must be concentrated in a small space, and engineers need time to deploy bridges or pontoons. In Ukraine, however, the problem has become a new dimension. Drones constantly monitor roads, accesses and banks, detecting any preparation for a crossing long before it occurs. This means that forces attempting to cross a river can be attacked even before reaching the water. What for decades was a complex engineering operation has been transformed into a race against time under permanent surveillance. A problem since the start of the war. Russian difficulties in crossing rivers they are not new. One of the most remembered episodes occurred in May 2022, when a Russian tactical group was practically destroyed during an attempt to cross the Siverski Donets. More than three years later, the problem remains unresolved. They remembered in Forbes That even relatively modest obstacles like the Vovcha River can slow down entire operations because the challenge is no longer just overcoming the water, but surviving the deployment process. Every bridge, every pontoon and every engineering vehicle automatically becomes a priority target for Ukrainian drones, artillery and other precision strike systems. The strange “Frankenstein”. Thus a scene has taken place that has remained recorded on video by Ukrainian forces. It happened when one of the most peculiar vehicles seen in the war appeared. A Russian unit built an improvised system using military truck chassis, probably Ural or KamAZ, transformed into a kind of articulated pontoon. The structure was made up of a drive section and a large adapted trailer, creating a set long enough to cross narrow sections of the river. Its appearance was so rudimentary and strange that Ukrainian observers compared it to a creation straight out of a Mad Max movie and they baptized as a four-wheeled “Frankenstein”. More than a visual curiosity, the vehicle reflected the need to find alternative solutions to a problem for which conventional means seem increasingly less effective. A mission observed from start to finish. The broadcast images by the Ukrainian Wolfhound unit show the complete route of the vehicle towards its objective. The group advanced at high speed through Vovchansk in an obvious attempt to reduce the time of exposure to possible attacks. During the trip, the trailer repeatedly left the road, knocked down an electrical pole and activated several mines without being disabled. Even so he managed to reach the river bank. However, Ukrainian air surveillance had followed their every move. As the soldiers began to deploy the system and the forward section began entering the water, several attack drones They destroyed the vehicle before he could complete his mission. A deeper problem. The most striking thing about the episode is that Russia has specialized teams capable of carrying out this type of operations. Systems such as launchable bridges MTU-72 or the PMP pontoons They were designed precisely to allow the passage of troops and armor through rivers much larger than the Vovcha. For a unit to resort to a such an improvised solution suggests that these means were not available in that sector or that the losses accumulated during the war have reduced their presence on the front line. It also reflects an industrial reality: the current priority is on producing tanks, armored vehicles, drones, ammunition and artillery, while engineering equipment receives much less attention and replenishment. Modern warfare forces us to reinvent everything. He “Frankenstein” by Vovchansk fits into an increasingly visible trend within the Russian military. In recent years, protected armored vehicles have appeared with anti-drone cagesvehicles covered with netsmodified robots for new features and all types of adaptations carried out directly by combat units. The speed at which threats evolve often outpaces militaries’ ability to develop and deploy new solutions. Although the makeshift pontoon was destroyed, its existence is revealing. It demonstrates the extent to which drones have disrupted a military task as basic as crossing a river, and how soldiers are attempting to fill the gap between battlefield needs and the ability of military machinery to respond with ingenuity, recycled parts, and emergency solutions.

Waymo’s ambitious plan to turn its batteries into gigantic solar powerbanks

The electric car industry has been grappling with an elephant in the room for years: what to do with the millions of battery packs that, while no longer useful to power a vehicle, still retain enormous energy capacity. Now, the answer could come with autonomous driving. Waymo has formalized a strategic agreement with the company B2U Storage Solutions to give a “second life” to the spent batteries of their robotaxis, preventing them from ending up directly in recycling plants to convert them into gigantic solar energy storage systems. The paradox of the robotaxi. To understand why this movement is so relevant, you have to understand how an autonomous car ages. As detailed Wall Street Journalthe life of a robotaxi is nothing like that of a private car. While our personal vehicles spend most of the day parked, Waymo vehicles operate as high-use shared assets. In statements to the financial newspaper, Adam Lenz, director of sustainability at Waymo, explained that this high utilization causes its cars to accumulate kilometers at a dizzying rate, forcing the batteries to be removed from commercial service much earlier than usual. According to data from Geotaba consumer electric car loses just 2.3% of battery capacity per year, retaining more than 81% after eight years of use. Robotaxis, however, suffer much more rapid degradation. But just because a battery no longer offers the range needed to safely carry passengers doesn’t mean it’s dead. The new business model seeks to squeeze the residual value of these batteries to use them in stationary applications, avoiding waste and taking advantage of critical materials that have already been manufactured. “Energy sponges.” When Waymo vehicles can no longer perform, B2U removes the batteries, tests their performance, and packages them in large metal cabinets about 2.7 meters high, similar to small shipping containers. Each of these containers houses dozens of units. From there, they function as true “energy sponges” for the electrical grid. During the day, when there is plenty of sun or wind and prices are low, the system absorbs and stores that electricity. It then injects that energy back into the grid during nighttime demand peaks, just when solar production drops. The economic and energy impact is notable. Freeman Hall, CEO of B2U, details that each reused battery can add between $8,000 and $10,000 in electrical value. Additionally, a single storage container has enough capacity to supply an average home for up to three months. Although Waymo has not specified an exact number of units, the goal in the long term it is to deploy “hundreds of megawatt-hours” of capacity, concentrating initial efforts in California and Texas, two states with great dependence and growth in renewable energy. The figures of an unstoppable fleet. As detailed Ars TechnicaWaymo currently operates about 4,000 vehicles, mainly consisting of Jaguar I-Pace with 90 kWh batteries, to which are being added the new “Ojai” models from the Chinese manufacturer Zeekr, equipped with 93 kWh batteries. This fleet makes about 500,000 trips a week, a rate that will only grow: the Wall Street Journal cites Morgan Stanley estimate which predicts that autonomous journeys in the US will go from 15 million in 2025 to 36 million at the end of this year. However, Waymo’s purely “green” narrative has its chiaroscuros, and the specialized press does not ignore them. Ars Technica Enter critical and necessary information: Although the company assures that its electric fleet avoids 530 tons of CO2 every half a million trips, its recent landing in Austin (Texas) together with Uber raised blisters. There, they used mobile generators from the company L-Charge powered by natural gas to recharge the robotaxis, which generated neighborhood complaints about noise and highlighted the logistical difficulties of operating electric vehicles without adequate charging infrastructure. On the other hand, companies like Redwood Materials (backed by Waymo’s own parent company, Alphabet) are also launching their own second-life storage divisions. All this occurs in a context of absolute record: in the first quarter of 2026, the US installed 9.7 GWh of stationary storage, an increase of 32% year-on-year. Beyond the green posturing. In short, this agreement seals a perfect urban circularity. As Adam Lenz reflectsthe same batteries that today transport passengers through their streets, tomorrow will be supporting the local electrical networks of those same communities. However, behind the obvious environmental benefit is a movement of pure business strategy: this is not just green philanthropy. Waymo depends on the electrical grids of the cities where it operates to be stable and robust to be able to keep its fleets operational 24/7. In the age of mass automation, shoring up the electrical grid with batteries from your own retired cars is no longer just an ecological medal; It is a strict necessity of business survival.

First he tied up Samsung, now SK Hynix. At the RAM crisis party, Nvidia has secured the cake

In any group of friends, there is one person who always tries to get along with everyone. In the technology world, that person is Nvidia. The American giant that until not so long ago was the one who dominated the conversation in the field of video game hardware, now it is synonymous with artificial intelligence. Nvidia is shaping the sector with billion-dollar investmentsbut also with its hardware. The H200 and the Blackwell B200 are the most coveted chips in the sectorwhich leads to everyone wants that platform and, therefore, Nvidia is one of the whales that is drinking the global stock of RAM. For Vera Rubin, their new platform, they need much more memory and, after reaching an agreement to ensure the best available that Samsung makesthey have achieved another with the other leg of the global RAM market: SK Hynix. And this is about data centersbut also eye-catching RTX Spark chiprobotics, accelerating development times and how consumers have years left to continue suffering with the supply of chips. Nvidia, SK Hynix and the deal to manufacture everything Jensen Huang, CEO of Nvidia, is traveling through Seoul. This time his objective was not to visit the new Samsung facilities (relations with Samsung They are already more than consolidated), but to secure the other South Korean (and world) memory chip giant: SK Hynix. During their visit, the two CEOs staged a multi-year agreement by which Nvidia will have priority access to the most refined memory coming out of the SK Hynix foundry. Because Nvidia already warned in January that this year it would need all the silicon possible, and seeing the roadmap it is something that is perfectly understood. As we say, they are immersed in the Vera Rubin AI platform for the training and inference of artificial intelligence models; have just presented the RTX Spark chips in response to Apple Silicon and Qualcomm chips for computers Windows ARM and then there’s another leg that we don’t talk about as much, but that they are pushing hard and that also requires a lot of memory chips: the Jetson Thor robotics platform. In it releasethe two state that this is an agreement to speed up development times on this hardware for AI. This is something that requires long development cycles, but also a lot of money to sustain the global demand for memory due to data centers for AI. This deal goes there. “AI factories are the drivers of the next industrial revolution, and advanced memory is essential to their performance” – Jensen Huang Because it is not so much about ensuring high bandwidth memory (something that Nvidia already had to be the great whale of the sector), but to improve the infrastructure so that the new generations arrive at the pace that the development of AI requires. In fact, Chey Tae-won, CEO of SK Group, highlights the same thing: “together we are co-developing the next generation of memory for AI factories, applying AI to semiconductor design and manufacturing.” That is to say, It is not a simple question of supply (which also, since 60-70% of SK Hynix’s HBM4 memory goes to Nvidia’s Vera Rubin), but to apply AI tools (which Nvidia has) for the design and manufacturing of semiconductors with the aforementioned objective of shortening times. This objective is something that is being pursued worldwide, and the company itself SK Hynix together with Samsung collaborate in a megacenter in the United States to streamline all these processes. As a result of this agreement, it is very possible that SK Hynix get its goal of setting up a fully autonomous semiconductor factory by 2030 (something that, again, share with Samsung). Now, what about the goal of those we want a RAM stick or one Steam Deck that doesn’t hit price increases of 300 euros at once? Well, unfortunately, we are going to continue eating this situation of debauchery when it comes to building AI platforms and gigantic data centers. During his visit, Huang himself commented that he expects the global shortage to last for years because the entire supply chain of this new industry depends on these chips and that demand is very high. In their wordsit is something that “will persist for several years”. They are not new statements either, since Huang gave about seven or eight years to the unbridled investment. And more important than all this, Nvidia, right now, has the four chip giants eating from his hand. SK Hynix and Samsung with memory and their factories for new generation memory. TSMC has turned Nvidia into your client A. And ASML that is what manufactures machines to make advanced chips It is the one that supplies those tools to the three mentioned. In Xataka | China already has a GPU that competes with Nvidia’s RTX 3060. The bad thing is that it arrives five years late and worse

In Asia they haven’t put ice in the water during meals for centuries. Digestive physiology just explained why they were right

The other day a friend told me about a peculiarity she observed during a recent trip to China: the glass of ice water on the table is almost a rarity. Instead you’ll find a pot of green tea, a bowl of broth, or just nothing cold. For centuries, in much of Asia, drinking cold liquid during a meal has been an eccentricity more typical of the West than there. What for a long time seemed like a quaint custom, or directly a matter of infrastructure—ice was not always available everywhere—turns out to have a pretty solid physiological explanation. The temperature of the water we drink while we eat is not a minor detail. It affects the movements of the stomach, the rate at which it empties, and how the muscles of the digestive system behave. And science, although with important nuances, is beginning to agree with what millions of people in Asia have been practicing for millennia. Before getting into the physiology, we must understand how this debate has reached the West. It has not been through a medical congress or a scientific journal. It has arrived, like so many other things, through TikTok. The phenomenon is known as chinamaxxing either Becoming Chinese: a viral trend in which thousands of Western people adopt lifestyle habits from Chinese culture, including drinking hot water. According to documents The New York Timeshot water has become “the new superstar of online well-being”, with influencers documenting how this habit deflates them, gives them energy and improves their digestion. But what the Internet presents as a revolutionary discovery is nothing new. This practice has been rooted for thousands of years. in Indian Ayurveda—where the morning ritual of drinking hot water is known as usha paana— and in Traditional Chinese Medicine, where cold is believed to “turn off the agni“, the digestive fire, and weakens the vital energy or Qiforcing the body to expend extra energy to warm the stomach. Hot water, on the other hand, balances the Yin and the Yang and keeps the body calm. Just because something is part of an ancient tradition does not automatically make it scientific truth, of course. But it doesn’t disqualify him either. The question is what exactly science says when it begins to analyze what happens in the stomach according to the temperature of what we drink. What really happens in the stomach? To understand the debate, we must separate two things that are often confused: the effect of drinking water during a meal and the effect of the temperature of that water. They are different questions with different answers. On the one hand, regarding water itself, there is a widespread belief that drinking water during meals dilutes gastric juices and digestive enzymes, slowing down digestion. Medical portals such as HealthLine They explain that there is no solid scientific evidence that water dilutes gastric juices or significantly hinders digestion. The stomach has a dynamic regulatory system that detects changes in pH and automatically secretes more hydrochloric acid to compensate. Drinking a glass of water during a meal hardly alters that balance. Marina Domene, head of nutrition at SHA Spain nuances in Vogue Where is the real limit: the problem is not drinking water, but excesses. “What is not recommended is drinking excessive amounts, more than two or three large glasses, as it could distend the stomach too much and temporarily dilute the enzymes,” he explains. It also points out that there are specific contexts where it is advisable to be more careful: in people who suffer from hypochlorhydria – low production of stomach acid – it is not recommended to consume liquids during meals. On the other hand, regarding temperature the panorama changes and this is where physiology begins to agree with Asia. The temperature of the liquids directly affects gastric motility, that is, the muscle movements of the stomach that drive digestion. Domene explains it clearly: “Cold drinks can slightly slow down gastric emptying and constrict the blood vessels of the stomach, which in sensitive people can be heavy. Hot liquids, such as broths or infusions, have a relaxing effect on the smooth muscles of the stomach.” This is not just a clinical opinion. There are studies that support this, such as research on the effect of temperature on gastric emptying have observed that very cold drinks, around 2-5 °C, can temporarily slow down the initial phase of gastric emptying compared to liquids at body temperature. Drinks at 4°C also disrupt antral and pyloric contractions, briefly retaining stomach contents. An experiment with 11 young men who consumed 500 ml of water at different temperatures found that water at 2 °C reduced the frequency of gastric contractions compared to water at 60 °C, and that lower muscle activity was related to lower subsequent caloric intake. The sample sizes of these studies are modest—it should be said—but their results consistently point in the same direction. A study published in Gastroenterology Nursingfocused on patients who had recently undergone colon surgery, observed that the consumption of hot water had a positive impact on subsequent bowel movements. It is not a study designed for healthy people, but it adds evidence about the role of temperature in intestinal motility. Gastroenterologist Dr. Lisa Ganjhu, consulted by The New York Timesdescribes it more graphically: during the night, the digestive system slows down. Hot water generates waves of contraction and relaxation in the muscles of the esophagus, stomach and intestines. “It’s basically telling everyone, ‘Okay, get up. We’ve got to get going,’” he explains. Why did they take that path and not another? The physiological explanation that science offers today connects quite well with what traditional Chinese medicine and Ayurveda have been saying for centuries, although in completely different languages. In China, Japan and much of Southeast Asia, It is common to accompany meals with hot tea or soup. It is not a fad or a recent trend: it is part of the structure of food. The broth does not close the menu, it accompanies … Read more

A bank convinced people in a poor town in the US to spend their savings. Now it’s full of millionaires

Stories of lucky breaks and millionaires there are manybut they almost always have a common denominator: we speak in singular. That is why what happened in a small town in Florida whose families were going through serious difficulties to get ahead is so special. Even today, the enclave continues to seem like a nondescript and inhospitable town. But don’t be fooled, a large number of millionaires still live there among the people. And all thanks to Coca-Cola. Quincy and the banker. This is the name of the town in one of the most fascinating stories of the United States economy. There, in the midst of the Great Depression of the 1920s and 1930s and with part of the census in serious difficulties, a figure appears who was going to change everyone’s lives. Your name: Pat Munroean astute banker, a businessman who focused on a key detail to convince all citizens. No matter how impoverished they were in Quincy or how dire the financial situation of the families, the man observed that almost religiously, people spent every penny on a nice ice-cold glass of Coca-Cola. What if that devotion turned it into a stroke of luck? Coca-Cola in a bag. The sugar giant It went public in 1919 at $40 a share.but a conflict with the sugar industry and its bottlers caused a 50% drop shortly after, when it reached $19 per share. Put another way, there was a time in history when Coca-Cola was trading for less than cash in the bank and its stock was extremely cheap. And among others, Munroe was at the right time. The bargain of the century. What did he do? Invest. The man began to acquire Coca-Cola shares as if there were no tomorrow. However, he did not do it alone. He encouraged all his acquaintances and friends of acquaintances in town to buy a stake in the company. Focusing on bottom line profits and brand power, Pat Munroe kept buying and buying. And as he did so he kept telling everyone in Quincy who would listen to him to buy too. He took advantage of the trust and respect the community had for him and went on a crusade to get anyone who could to get on the Coca-Cola train. Loans for shares. The man was so sure of his success that every time a person went to his bank to ask for a loan, encouraged him to accept another in exchange for shares. Farmers, shopkeepers, teachers: absolutely anyone who could spend money was tempted by Munroe. For the banker, the fact that Coca-Cola shares were at $19 each was an opportunity that no one in the city should escape. That is why he never tired of urging people to buy and, almost as important, to remain firm in the decision regardless of the market fluctuations that occurred in the short term. The ball Finally, the banker’s observations turned out to be a historic success. Quincy, an eminently agricultural city, not only stayed afloat in difficult times thanks to Coca-Cola dividends, brought a wealth that is still studied in universities. In fact, the enclave became the richest city per capita in the entire United States for a time, and dozens of its inhabitants were nicknamed “the secret Coca-Cola millionaires.” People who trusted Munroe’s good eye and invested all their money (and what they didn’t have), and who amassed enormous fortunes with those first shares, which they then passed down from generation to generation, turning them into the eponymous Coca-Cola millionaires, ones who, effectively, established entire dynasties of financial prosperity that transcended generations. How much are we talking about? It is difficult to speak in total terms, but to give us an idea of ​​the money, in 2013 it was made a study evaluating what happened in Quincy. The results showed that a single share with reinvested dividends was worth $10,000,000. $270,000 in pre-tax cash dividends would be sent to the owner by sending a check for approximately $67,500 in March, June, September and November of each year. Thus, if the great-grandmother and the great-grandfather on duty had acquired a round lot of 100 shares for between $1,900 and $4,000, depending on the purchase price, they would have more than a billion dollars, excluding the effects of estate taxes. By the way, the current value is considerably higher, since the stock has more than doubled its price since then and the quarterly dividend now exceeds $0.53 per share. Money for crisis. That investment has been a lifesaver every time a tough time approaches. When the local economy was supported by coca and the crisis arrived, tail dividends. In fact, these assets have supported the city through every recession since. When crops failed, it was Coca-Cola money that kept people employed. When the national economy collapsed, it was Coca-Cola’s cash that allowed people to stay in their homes. When times were good and Coca-Cola was cheap, they bought more shares. Quincy today. It is a unique story, because it is unusual. Every family that amassed a fortune then passed it on to their children and grandchildren, in some cases through direct donations and in others through the use of trust funds. Even the bank where it all started has a Coca-Cola on display and, according to data from the early 2010s, a staggering 65% of trust assets under management were still invested in Coca-Cola stock. Quincy’s appearance today is not much different from the Great Depression era. It remains a quiet and eminently agricultural city with a population around to 7,000 inhabitants. But don’t let your eyes fool you, some of the grandchildren whose families built an empire, that of the secret Coca-Cola millionaires, still walk through those streets.
