Cover letters were a treasure for recruiters, until AI turned them into wet paper

November 5, 2025 by usatoday24

AI promised to speed up the processes of staff recruitmentbut after a period of intensive use of AI by both companies and candidates, it has been shown that It’s more broken than ever. Further proof of this degradation are cover letters which, although before the arrival of AI models were a clear differentiating factor, are currently worthless, as a study by Princeton University and Dartmouth College has shown. Cover letters made a difference. The study ‘Making Talk Cheap: generative AI and Labor Market Signaling‘ carried out by Princeton researchers analyzed more than 2.7 million proposals on the Freelancer.com platform before and after the implementation of the LLM text generation models to create these cover letters. Their conclusion is that, before using AI, attach a well-written and to show interest and knowledge of the position and the company to which one was applying, considerably increased the hiring options because the recruiters perceived that this was a very capable candidate. Now they are wet paper. However, as the use of AI tools to generate these cover letters has spread, the appreciation of quality has improved so that candidates in the top 20% of writing skills were 19% less likely to be hired, while those in the lowest 20% increased their chances by 14%. In other words, employers stopped associating a well-written letter with a competent candidate. This has meant that the differentiating factor that a well-written cover letter previously provided has disappeared, reducing the curve of possibilities between the best-trained candidates and those who are not so well-trained. Letters submitted before the LLM models had a better chance of being hired than those post-LLM AI makes hiring more difficult. The effect observed in cover letters has been extended to other areas of personnel selection, since AI distorts real capabilities of the candidates. It is true that its use increases the perception of quality of the candidates, but as the average quality of the group increased, companies began to trust less in the information provided by the applications. He study ‘Does AI devalue communication? Theory and evidence of entrepreneurship and contracting at a global level’ carried out by researchers at Columbia University and Yeshiva, found a similar pattern in selection and entrepreneurship processes: access to AI reduced the accuracy with which recruiters identified the best profiles to fill a given vacancy by between 4% and 9%. If everything is good, nothing is good. For decades, a letter well tailored to the offer served as proof of interest and commitment on the part of candidates. In labor economics, this is known as “signalling”: the candidate conveys their effort through the quality of the text. Generative models have thrown that signal to the ground. The meta-analysis ‘The role of artificial intelligence in personnel selection’ concluded that the automation of selection processes with AI is eroding the traditional signals of merit that were transmitted through cover letters, emails or applications received by the hiring and human resources departments. In that sense, while it is true that AI has democratized competition in the job search, it has also made genuine talent less visible. Who is behind the algorithm? The current degradation of those “clues” that allowed recruiters to locate the best talent, forces us to look for new ways to evaluate candidates. As and as they pointed From the technological employment platform Manfred, the use of AI has multiplied the number of applications, but the perceived quality has not improved at the same pace. For this reason, many companies are choosing to implement more practical tests and face-to-face interviews in their selection processes. That is, eliminate from the equation the presence of AI for the last stage of the selection process. The unknown of this practice is knowing how much talent has succumbed to AI resume filtering prior to that first face-to-face interview.

We take for granted the conveniences of the digital age: instant messaging, online shopping, the databases that power millions of businesses. Everything flows until something breaks and the routine stops. In companies, this failure can have devastating effects. Jaguar Land Rover verified itwhich suffered a cyber attack that paralyzed its production lines. Now the scenario is repeated in Japan, where Asahi, the giant that controls about 40% of the beer market, has had to stop its activity and resort to the most basic: handwritten orders, paper documents and faxes that ring again. The incident broke out at the end of September, when an attack by ransomware left inoperative Asahi’s ordering and shipping systems in Japan. In a few hours, the company had to suspend activity in most of its factories and completely reorganize its logistics. The country’s supermarkets and convenience chains, including 7-Eleven and FamilyMart, warned of possible stock shortages. Although production began to resume on a limited basis, the brewer admitted that it could not guarantee timelines for returning to normality. When a cyberattack turns off screens and forces you to return to paper The systems that allow Asahi to process orders, coordinate deliveries and communicate with distributors were out of service following the attack. Although factories could continue producingthe company was forced to stop activity because it could not manage a single shipping order. The measure was part of the containment protocol, which included blocking servers and suspending incoming mail from abroad. In a few hours, the largest brewer in the country went from total automation to an almost complete stoppage. Faced with the digital blockade, Asahi activated an emergency plan based on manual procedures. Orders were written down by hand, delivery notes were printed and shipping confirmations were communicated by fax, as they were decades ago. The goal was simple: keep the product flowing, even if it was limited. The brewery thus managed to partially reactivate its distribution network, while preparing the reopening of its call center. It was a slow and laborious response, but it allowed the first batches of beer to leave the factories again. Little by little, Asahi began to commission its factories. The six brewing centers in the country returned to limited production, starting with the Asahi Super Dry line. Some soft drink and food plants were also reactivated, although at a slower pace. The company specified that its production was still far from normal and that containment measures were still in force. The attack affected only Asahi’s domestic operations. The company clarified that its subsidiaries in Europe and the United Kingdom continued to operate without incidents. The Japanese side, which contributes around 50% of its global incomewas the only one hit. Although the geographical scope was limited, the economic and logistical effect within the country was notable. A group called Qilin sand claimed responsibility for the cyberattack. We are talking about an organization that operates under a “ransomware as a service” model and that has already been involved in attacks on large companies. Asahi did not confirm that version or detail the type of intrusion. In any case, The Japanese Government maintains an investigation open to clarify what happened. Asahi is keeping its recovery plan underway, focused on gradually restoring ordering and shipping systems. As we say, the immediate priority is normalize production and fully reopen its customer service center. Starting in mid-October, the company hopes to increase the pace of distribution and recover part of the catalog affected by delays. It has not yet set a date for full restoration, but it assures that security measures will be reinforced before returning to one hundred percent operation.

More than 200,000 books for 11 euros a year. It is ‘The Free Books Club’ of Valencia, a paradise for printed paper devotees

September 7, 2025 by usatoday24

In a city like Valencia, not precisely lacking second -hand librariesa project has been born that goes beyond the mere business with volumes that have already lived one or more readings. It’s about ‘The Free Books Club ‘, a mixture of bookstore, paper trace, social club and NGOs Bibliophile that, in exchange for a minimum fee, allows its partners to take all the books they want. Its responsible is Rafael Soriano, who transmits an enthusiasm for reading perfectly In line with the philosophy of the premises: “All books are jewelry, some need a little mime and that is the goal of the club: save the books, pass them from good hands to others and in that way, among all, to have an immense library of people who want to continue keeping the books.” All books They deserve be read (As Rafael says, “a book can be a brick, but if you find a page, a paragraph, a text that tells you something, is already a good book”) and therefore preserved. That is why the Free Books Club ‘has an affordable partner share, 11 euros a year, which allows you to take all the books that are desired (To donate it is not even necessary to be a partner), return them or keep them if desired. The intention of the club is that no book is discarded, and of course, that leads to problems. The main one is that Rafael stopped counting the specimens in the premises when he reached 200,000, and the lack of space has forced him to stop classifying, archiving, listing and even restore those volumes they need. In the original place there are no more volumes, which has led them to resort to “partners who have some space at home, a garage, a small warehouse. When someone requests a large rescue, let’s say ten, twelve, fourteen boxes of books, in the premises of Valencia they do not fit.” The project has thus became a completely collaborative idea: the website centralizes the calls for help in search of space, and They estimate that right now they will be around 300,000 “saved” booksas Rafael likes to say. There are future and expansion plans although at the moment the relief comes from projects as another open club in Padrón (A Coruña) with similar operation. An agreement with emails has also been reached so that the partners can exchange books directly without going through the Valencia premises, again with the website as a meeting point. Although Rafael’s ambition goes further, and would like to see premises like his in other provinces, and “that the partners can take a book in Valencia, leave it in Cáceres, take one in Cáceres and leave it in Barcelona.” Computer to Guardian de Books Rafael Soriano started his career as a computer programmer: “I started computer studies before there were computer faculties. In the year 85 I started from 88 I dedicated myself to programming for different clients. In the end the fort of my programming was the management of bars and restaurants. “Later he made the leap to the other side of the screen:” For having met the sector, I was as manager of a bar-restaurant for a year, with thirty-so many employees on the beach. “ After dedicating almost ten years he transferred him and stayed “a little in limbo: I am not yet retired, but I don’t want to be at home, even if I have some resources to endure.” And in this way the club was born: “A little like Hobby, a little as a refuge.” And near the sea, “because I like to swim, see dawn swimming.” A completely born project of devotion to the printed page and has set in something more than a bookstore: A home for old books that serves as a transit in search of new houses. Or as Rafael says, “it is an alchemy workshop, that is, everything that is there is paper, it is an piled paper, but in the right hands it becomes gold.” In Xataka | Before he died, this man left a list of everything he had read in his life: 3,599 books of all kinds that you can now consult

To play Dungoons & Dragons you just needed ball, paper and dice. Now a course of 2,000 dollars wants to teach you better

August 3, 2025 by usatoday24

To direct a game of Dungoons & Dragons, the legendary role -playing gamejust a dice, a paper and a pencil. Okay, you need to know basic rules, but essentially traditional role -playing games are a lot of friends using their imagination to develop stories. the D & D Dungeon Master University It is willing to end that: one thousand euros for an accelerated and official role of role in a luxury environment and surrounded by experts in the field. It is not an eccentricity: it is the last sample of the tendency to become the luxury experiences of the simplest hobbys. What is this university. A luxury retreat that teaches you all the secrets of the role of role games. There are subjects such as skill development, campaign creation, world construction and professional development. It will take place at the Oglethorpe University of Atlanta. The courses will be on January 2 and 3 of next year, although students who are from January 1 to 4 are asked (a bit complicated dates, if they ask us). As for prices, they range from $ 995 to 2,250, which includes private meetings and games with teachers and other advantages (such as an exclusive jacket). But who are these people. The event is organized by the people of D&D in A A A A, organizers of immersive retirement events that they offer Dungeons & Dragons experiences within real castles (All officially and in collaboration with the owners of the brand). For four days, players of all levels play the role in marathons that arrive at 24 hours and with all the comforts (food, accommodation) inspired by the game. Of course, there are parallel activities (workshops, miniatures, Escape Roomsarchery …) to foster the community, in what becomes a kind of thematic cruise, but dry. Make community. In principle it seems an eccentric luxury, but it is only another way to create new physical ties in hobbies. As he counted This great article about The Verge Comic-Con, Sharing our hobbies is an extremely healthy attitude and the Dungeon Master University and his older sister, D&D in A Castle, are ways of promoting them. Increasingly, conventions, courses and encounters are ways of prolonging our leisure and free time, and there are even websites, such as Meetup, Classbento in the United Kingdom or Fancoons in the US that are responsible for listing and announcing these types of activities.

Every time someone tells me that his mobile is slow, I know where to look: the “paper” of WhatsApp

July 16, 2025 by usatoday24

WhatsApp’s storage is something problematic for a long time. So much that, over time, those responsible have had to develop different forms of release conversations spacevideos, photos and audios on our smartphones. Today they are enormous help, because I have proven that unless we install giant games or we love to carry a good videos library in 4K, the greatest enemy of our mobile is the WhatsApp download folder. Every time someone tells me that his mobile is slower, the first thing I do is look at how much free space he has. And bingo: WhatsApp is usually The biggest glutton in iOS and Android. WhatsApp tricks and tips to hide you to the fullest and maintain your privacy WhatsApp vs Storage, a not solved historical conflict. WhatsApp problems with the space occupied by their files come from the time when the iPhone had 8 GB and it was normal for Android to use internal storage and microSD cards. “That is the solution, more storage,” we thought. But no, unlike Companies like Samsung and its ‘hacks’WhatsApp never allowed their files to move to secondary memory, so releasing memory was generally deleting files or moving them. In the latter case, however, they stopped appearing linked to our conversations. That storage devourer called WhatsApp. A full mobile, a slow mobile. As the storage is filled, the performance of a low device. It is so in telephony, in tablets, in classical computer science or on televisions. An operating system and its applications need a minimum space to execute reading and writing operations. When the storage is almost full, modern systems try to release space by erasing caches and other temporal files, but where there is not, it cannot be taken out. In computers it was also important to have free space for the use of virtual memory, but with the Virtual RAM extension which include many manufacturers, the problem is also aggravated in mobiles. The recommendation: Disable this function That neither Google itself advises to use, because it wears the memory. In 2025 there are good solutions. Unlike what happened in its beginnings, today WhatsApp does have Good solutions to free space. Before looking at a capture like the superior, it meant frustrating and deleting video by video, photo by photo. Today, after detecting that a mobile is so full, the first thing I do and advise is, inside WhatsApp, go to ‘Settings – Storage and Data – Storage Administration’. Once we have selected the files to erase, the right appears down to the right. There we will find ourselves A complete menu where the application informs us how much space is occupying and how it distributes it. First, it shows, without ordering, files of more than 5 GB. Entering is a great filter to find some large attachment that will quickly help free space. It is also very useful the ‘forwarded of many times’ section, as it is very common for us to get the same video forwarded from different groups, and WhatsApp duplicates them. If we scroll, we will reach the space occupied by the conversations of our individual groups, chats or channels. By selecting each of them, we will see which files occupy more by order, and we can make a quick selection and delete, from the paper icon to which the red arrow of the upper image points. Get to reach this point. Deciding what to delete can be exhausting, no matter how easy the WhatsApp assistant is given to us. So it is best to avoid a situation in which WhatsApp ‘eats’ 32 GB, as in catches. How to achieve it? WhatsApp itself gives us the advice: ‘Activates temporary messages’. If we do it in our groups or chats, the messages will be deleted after 24 hours, 7 or 90 days, according to us. The occupied space will also be released after that time. If we want everything to still not be deleted automatically, but we want to better manage space, in ‘storage and data’ we can also Disable file automatic downloadchoosing according to file type if we want nothing to be downloaded automatically (which would be the ideal option for WhatsApps full of photos of groups that we do not consult), or only in Wi -Fi or Wi -Fi and mobile data. In ‘Settings – Storage and Data – Automatic file download’ we find the option to choose which files we want to be downloaded automatically. If we select ‘never’ we will totally control what our space is invaded and what not. On the iPhone, personally, too unleash the option ‘Save in photos’ that we find in ‘adjustments – chats’. I do it because that function makes all WhatsApp photos also go to the reel of iOS, which doubles them without any use for me. Other people, yes, choose to activate it for backup apps such as Icloud or Google Photos keep everything in the cloud. This WhatsApp option in iOS avoids duplicate files on the reel. If the deactive, the photos will continue to be on WhatsApp equally. More radical solutions. That WhatsApp storage can become a problem is not something invented. Personally, I have come to deal with mobiles that had 70 GB occupied by WhatsApp. When he has come to occupy so much, and we do not mean goodbye to everything, there is a magnificent more radical option such as ‘Export Chat’, which generates, if we want, a file compressed with all our conversation (in flat text) and all our files. In each of our conversations and chats we can export the historical content, choosing to save files or only the text. The pity is that there is no import option. It works very fast, so in seconds we can have the file in our memory, ready to be sent to a PC where we can have all the text, audios, videos and other files in the group. The background problem. WhatsApp is eaten a lot of storage, it’s true. But the real … Read more

There are people recommending to sew the leg on albal paper. There is zero evidence to work

June 10, 2025 by usatoday24

From vinegar with bicarbonate to garlic under the pillow, home remedies have been for generations a popular resource for calming pain and treating discomfort. Today, those beliefs travel faster than ever: they have passed from the whisper between neighbors to the Tiktok algorithm. Between viral recipes and striking promises, there is one that stands out for how strange it is: wrapping body parts with aluminum foil to relieve pain. The phenomenon. On platforms such as Tiktok and Instagramthe tips that recommend using aluminum foil on the body to relieve pain or improve circulation have become viral. Often these publications are presented as secrets that conventional medicine He doesn’t want to reveal. Some people claim that the effect is more powerful if combined With ointments like Vicks Vaporubwhile others simply describe it as a “natural remedy”. The trend has caught so much attention that various digital media echoed, either to explain How has it popularized either Explain how to do it without major contrast. It is another example of how contents without scientific basis propagate easily thanks to short videos, personal testimonies and a language that sounds convincing. Hence half the world, stunning the leg on aluminum foil there is only one scroll away. The science behind this. There is no scientific evidence that supports the use of aluminum foil to relieve pain. Only in an investigation Published in Journal of Inflammation Research The use of different materials between this aluminum is mentioned, but the conclusion is that it has no therapeutic effects proven in humans. It is mentioned that the relief that some people They claim to experiment It is probably due to the placebo effect. For his part, Dr. Ubaid Ur Rahman, in statements to Thip Media, It is clear about it: “I want to clarify the confusion about a recent statement that wrapping body parts with aluminum foil can relieve pain. This is not backed by scientific evidence.” And add an important warning: “Using aluminum foil can be harmful, since it can cause tissue damage and allergic reactions. It is essential not to delay proper treatment or replace it with unseed methods.” A relief that is not. The placebo effect can explain part of these experiences. From Harvard Health They explain that it is not about “positive thinking”, but a response from the body that can relieve symptoms when we believe we are receiving a treatment. But that does not turn aluminum foil, nor justify its use as a substitute for medicine. Belief can generate a temporary improvement, but the risk is in what is stopped in the meantime. He no longer catches us by surprise. In social networks, other trends are not to be amplified that, under the pretext of “natural”, are implying real risks. Such as Apple vinegar consumption As a “morning suck”, promoted as “fat burning” or “purifying”, which ends up damaging tooth enamel and causing gastrointestinal irritations. Another example is the fashion of Eat placenta After childbirth, which has gained popularity in some circles even though there is no evidence of benefits and sanitary warnings. The amplification. In social networks, remedies are amplified quickly, many times without filter or context. Some may have a valid background; Others, such as the use of aluminum foil against pain, lack scientific support and can distract effective treatments. The key is to discern: question, contrast and, above all, not replace evidence with virality. Informing well is also a way to take care of yourself.

The World Cup, paper, scissors exists. And it is a very serious thing

May 11, 2025 by usatoday24

Netflix has taught us with ‘The squid game‘That children’s games are a very serious thing. As we grow, we stop playing most of them, but there is such an entrenched one that we use it when it is discussion or to decide something quickly: the stone, paper and scissors. And it is so important that there are even World Cups with thousands of dollars at stake. WRPSA. In this story, it is difficult to differentiate what is a joke from what is serious. Your YouTube channel seems a parody, and in the gallery of its website they modify works of art so that it seems that are playing this game and they have even one section of browser games that call “simulators.” But no, the World Stone Association, Scissors exists and is not an American, as we might think, but has a presence throughout the world. The adventure of World Rock Paper Scissors Associationor WRPSA, began in 2015. He was not born out of nowhere, but taking the witness of the World Rock Paper Scissors Society who had already held international championships between 2002 and 2009. And both one and the other organized tournaments of what you are thinking: stone, paper and scissors, facing those who consider them as the best players in the world and giving juicy awards. Rules. Should we explain how it is played? Basically, participants simultaneously perform one between three gestures: stone (closed fist), scissors (two extended fingers forming a ‘V’) and paper (the palm and all extended fingers. The mechanics is that the stone wins the scissors, the scisso known However, to compete in international events, at least with the rules of the WRPSA (Lizard and Spock are gestures that are not allowed), there are a number of elements that we must take into account. The first thing is that players must show their gesture at the same time. The hands should be hidden until the gesture is launched, they should look into each other, the best of three, five or seven rounds is played, there is a variant by teams and referees that are responsible for not cheating. Strategies. This game seems pure random and, obviously, there is a very, very important factor of randomness, but there are also some strategies that can be used to increase the possibilities of victory. Some are logical, such as not always using the same pattern, since it is something that can be used against you. Others have more psychology behind. For example, the research They suggest that winners tend to repeat their movements, while losers change to another gesture. Therefore, if you win, you are more likely to repeat the gesture and, if you lose, you can take advantage of the fact that the repetition trend exists in the winning case and trying to anticipate. For example, if they beat you with stone, the opponent may once again use stone, so you would get the victory. The best play to win? May your tactic be randomly. A Chinese mathematician named Zhijian Wang discovered that the most precise way to win is by choosing a random strategy. Also discovered That the most common pattern among the losing players of his study was precisely the stone, paper and scissors, in loop. Damage. As a notion in case you want to become a professional, it is not bad, but … Do you earn money? Depends. In the annual edition of the World Rock Paper Scissors Championships of Toronto, a main prize of up to 10,000 dollars is offered. The Rock Paper Scissors League From the United States, which organized events throughout the territory, distributed prizes of between $ 1,000 and $ 5,000. Other minor tournaments offer food checks, gift cards or film tickets for a year, but when a large sponsor gets into the equation, the monetary amount triggers. It was the case of the 2005 “championship” starring the Bud Light brewing brand, which during the Super Bowl of that year gave a prize of one million dollars. In 2006 and 2008 He sponsored The American League with a prize of 50,000 dollars to the champion and a pass for the international championship held in China. Jump to Europe. Some of these championships have been broadcast on television and, apart from the commented, some minor tournaments have been held that have cash awards, but above all they are a drinking food party with a good atmosphere. And in Europe we have not been left out of this peculiar sport. Perhaps, the most famous league on the continent is organized by Wacky Nation in the United Kingdom, giving prizes of up to 20,000 pounds in the 2019 edition. In Spain, the awards have been somewhat more modest, something curious if we take into account that culturally it is a game that is frequently used to decide something in a simple, fast and fair way. In 2023, the Polytechnic University of Valencia celebrated The first stone, paper and scissors tournament, a closed competition to its students, with 128 registered and with an award that consisted of a paratrooper experience for two people. Last year, the Caja Rural de Navarra and the General Commission of the University Tent They celebrated A tournament with 64 participants and 500 euros of the winner, 200 euros for the second and 50 for the third. Asia to your roll. But if we were talking about the finals of a World Cup in China before, it is because in Asia, as usually happens, they are at another speed in this type of issues. It makes a lot of sense, in reality, since in China it is where, during the Han dynasty (206 AC to 220 AD) there was a game called Shǒushìlìng It is the predecessor of the current game. China arrived in Japan in the seventeenth century, where it adapted and consolidated with the gestures and rules we use today. After the 2008 Olympic Games, the Championship of the International Stone Federation, Paper and Scissors with … Read more

Among those debates there is one that never seems to disappear because both sides have it as clear. We refer to toilet paper and correct way to hang it. If we take decades to achieve a significant advance of the roll, it makes sense that the controversy has endured. The funny thing is that the answer was from the beginning. A “war” of the century and a half. Eternal dispute over How to hang up The toilet paper (with the “above” or “below” sheet) has generated opinions found, family debates and even discussions lit. Those who prefer the “OVER” method (above) Feel practical and hygienic reasons: it is easier to locate the end of the paper, reduce the risk of wall contact (and therefore with germs) and is visually more orderly. However, on the other sidewalk, the supporters of the “under” (below) appeal to a more discreet appearance and the fact that, for example, it makes it difficult for pets or children at home unwind the whole paper. An enlightened invention. However, all this controversy seems to have found an official response in an unexpected place: a document more than 130 years ago. In 2015, writer Owen Williams He rescued an image historical of Google Patents Archives which showed the patent recorded in 1891 by Seth Wheeler, nothing more and nothing less than the inventor of the perforated toilet paper. In it, it is clearly enlightened how the paper should be hung: above the roll (image below). The patent, registered by Albany Perforated Wraping Paper Company, includes unequivocal diagrams in which the paper unwinds from the front. The Wheeler patent Wheeler’s reasons. The inventor not only patented the concept of perforated paper in 1871, but, two decades later, perfected the roll design, with the intention of minimizing waste and facilitating its use without the need for complicated portarrolls. Your goal It was efficiencydo not feed endless debates: “My improved roll can be used in simpler supports,” wrote in the text of the patent. In its original conception, the paper had to fall forward to facilitate the individual tear of the perforated leaves, thus avoiding accidental unwinders or an unnecessary waste. Yes, Nokia played toilet paper before mobile Rescue science. There are more data that corroborate that the “pro-insane” are right. Science also supports this orientation for purely health reasons. According to Dr. Christian Moro explainedProfessor of Health Sciences at the Bond University, hanging the paper with the blade above reduces the risk that users touch the rear wall of the support when looking for the end of the roll, which can minimize that propagation of bacteria. Moro remembered that among the potential infection agents which can be found in the bathrooms are streptococcus, staphylococcus, E. coli and common cold viruses, all capable of transmitting through contact with contaminated surfaces. Preventing the hands from entering unnecessary contact with the wall or roll support is, therefore, a simple but effective measure to reduce the risk of infection in shared spaces. An invention … to review? Beyond the debate on how it should be placed, in recent years others have appeared around the invention. Explained the New York Times In a column that although its invention represented at the time a technical improvement with respect to previous methods (which included, attention, leaves, marine shells, sticks with sponges or even reusable ceramics), the persistence of its use reveals less a functional efficacy than a cultural resistance to abandoning the family. Here appears the Covid-19 Pandemia, at which time the toilet paper acquired An unusual prominence: Not because of its medical utility, but as a symbol of control against chaos. The Collective hysteria He led to empty shelves, ignoring that neither the supply was threatened nor the role was the most hygienic solution. And despite this, experts agree that it is far from being the cleanest or healthier option. The evidence. The Times explained That researchers in infectious diseases and colorectal health agree that the exclusive use of paper does not guarantee adequate cleaning and can, in fact, cause irritations and favor disease transmission. Among the pathogenic agents that can survive in poorly eliminated fecal remains are those germs and bacteria that we comment before and that are the cause of urinary infections. Even traces of the same were detected Coronavirus at the time in human feces. According to Dr. H. Randolph Bailey, colorectal surgeon in Houston, many anal ailments that he observes in consultation come from Excessive cleaning or with inappropriate products, such as wet wipes with irritating perfumes and chemicals. Water as a solution. Here a parallel debate opens, surely more bitter. The reason? The most hygienic method, according to many specialists, is the rinse with water, either by drums or similar. In Japan, for example, smart toilets with jets of warm water They are the normwhile in the West adoption remains marginal. The reasons are not technical or economic (today there are compact and accessible solutions), but rather cultural. Bidé rejection has been historically associated with prejudices of modest During World War IIwhen American soldiers met the bida in French brotheses, which made them “suspect” objects. The anecdote of an American tourist who confused it with a bathtub For babies illustrates to what extent the discomfort in the face of the unknown has stopped its adoption, even in France, where it was originally common. O Tallitas. In recent times a “plan C” has emerged in front of the fundamentalists of roll or water: wet wipes. The problem is that it has been accompanied by Environmental consequences. Its accumulation in sewerage networks, combined with fat and waste, has given rise to huge obstructions (known in the world Anglo as “Fatbergs“) capable of collapsing urban sanitation systems. Under that prism, instead of improving the panorama, the wipes have added a new problem to another already existing one, fed by an industry that promotes … Read more
