Schwarzenegger continues training every day at 78 years old and the fascinating thing is that he is right

by

At 78 years old, the seven-time Mr. Olympia and the most famous cyborg in the history of cinema continues to faithfully attend his appointment at the gym, as Schwarzenegger acknowledges in an entry on his personal blogwhere he explains that even on days when he has less energy he goes to exercise, something that sums up pretty well with the phrase: “No matter the pain, no matter the weight, every day I achieve a victory.” It’s a reality. His mentality, forged in the golden age of bodybuilding, might seem like the eccentricity of a Hollywood star who refuses to age. However, behind Schwarzenegger’s weights and pulley machines lies one of the most robust physiological truths of modern medicine: strength training starting at age 70 and 80 is not an aesthetic whim, It is a medical necessity. Falling into the stereotype that sport is for young people who want to show off having a good body on the beach is real nonsense, because playing sport literally becomes the next prescription for all the benefits it entails. And logically being more or less old here does not at all condition entry to a gym, as science recognizes us. Inactivity weighs more. To reach old age in better health, you don’t have to invest a lot of money in super expensive supplements or creams to keep your skin firm. And there is a widespread belief that the loss of functional capacity and weakness are inevitable consequences of getting older, but here the National Institute on Aging from the United States is blunt about it: in the vast majority of cases, physical inactivity weighs much more than biological age itself in this deterioration. One of the great silent enemies of middle age is sarcopenia, which is the gradual loss of muscle mass and strength, and which literally correlates with both quality and life expectancy. And to correct it, the only treatment we have at hand is to do strength training adapted to each person profile, directly improving our ability to perform such everyday tasks as getting up from a chair, walking to the supermarket or carrying shopping bags. It’s never too late. Another of the great myths that we also have on the table is that you are too old to start exercising, but here the scientific literature reminds us that it is false, since starting late is still (very much) worth it. Here, a study that grouped 121 randomized trials with 6,700 participants showed that progressive strength training improves muscle strength and functional capacity in older people. This resulted in an improvement in autonomy by significantly improving their walking speed and their ability to climb stairs autonomously. Besides this, a recent systematic review of the Polytechnic University of Madrid on training in older people reported that traditional strength training can achieve improvements in knee extension strength of up to 46%. That percentage, in clinical practice, is the difference between needing a walker or walking on your own. Beyond the muscle. Strength work is also important for bone formation and combating osteoporosis by reducing several cardiometabolic risk factors. Besides, the Heart Foundation points out that strength work, added to balance and mobility training, is vital to protect against falls. It is not something minor, since in people over 70 years of age a fall is not an accident, but rather it is one of the most serious clinical problems that can drastically reduce life expectancy. Added to all this is that exercise has been shown to help regulate sleep, improve mood (reducing stress and anxiety) and even protect cognitive function. Adapted. There is no need to try to emulate Schwarzenegger’s youth records to obtain these benefits, but current medical guidelines agree on a minimum effective dose that is very affordable for almost everyone. In this case, for a person over 70 years old, a reasonable guideline supported by evidence is to train strength at least 2 days per week. But here you should always adapt the exercise to each person and start with a gentle exercise and gradually increase it. Although you don’t just have to be with the dumbbell in your hand, it should be combined with balance routines, joint mobility and some aerobic work.

start sleeping 8 hours every day

by

Almost all of us know that sleeping poorly takes its toll on us the next day, where thinking becomes a task that it’s not easy at allin addition to having fewer reflexes or simply being much more tired. However, what happens inside the body when we alter our hours of sleep goes far beyond simple fatigue and contributes (a lot) to our aging. This is what a monumental study has pointed out, putting figures on this phenomenon. The essay. A recent investigation published in the prestigious magazine Nature has analyzed approximately 500,000 adults to find out how sleep duration affects our “biological age.” And the verdict, after measuring the state of almost all our systems, draws a very clear U-shaped curve: the sweet spot is between 6 and 8 hours a day. The biological clock. What makes this study a milestone is not only its gigantic sample size, which gives it enviable statistical power, but its approach. And normally aging studies are based on very general blood markers, but now science has opted to cross-reference data from genomics, proteomics, metabolomics and medical images. With all this information, what they have done is nothing more than create 23 different “aging clocks” that represent the state of 17 organs of the human body. This has allowed them to map in a coordinated way the relationship between the brain, which is affected by this lack of sleep, and the rest of the body. A curve. The main finding of this article focuses on the fact that the relationship between sleep and the level of aging does not follow a straight line, but rather has a ‘U’ shape. This means that people who systematically sleep between 6 and 8 hours have a lower “biological age” compared to their chronological age, in addition to having better general health. But at the extremes, both sleeping less than six hours and sleeping more than eight hours are associated with accelerated aging in most of the organs that have been analyzed. Because? There are reasons for both excess sleep and not enough sleep that justify this accelerated aging. If we focus on people who sleep little, we must take into account that during sleep the brain expands its channels to “clean” the accumulated metabolic waste, which interrupting it can cause accelerated brain aging. But in addition, lack of sleep increases the levels of pro-inflammatory molecules and we already know that inflammation sustained over time can cause irreversible damage to organs. Also in excess. We may think that sleeping a lot is the best thing there is, but the reality is quite different, as this study points out. The reasons for this are that spending 10 hours in bed does not mean sleeping well for 10 hours, since people who sleep ‘a lot’ tend to have fragmented, superficial sleep with micro-awakenings. This means that they spend more time in light phases and less in the restorative sleep that we value so much. But we must also keep in mind that sleeping for a long time can be a symptom of an underlying disease such as depressionsleep apnea or chronic inflammation that is not the cause of aging as such, but does cause great damage to the body. There are nuances. Although the data on the table are quite robust, the study itself points out a crucial limitation that is often the Achilles heel of epidemiology: the association does not prove chance. This means that we don’t know if we age faster because we sleep too little or if we sleep too little because our body is aging due to an underlying disease. As epidemiologists who have reviewed this type of literature point out, forcing a person to sleep 7 hours does not guarantee that their biological clock will suddenly turn back. Furthermore, the researchers themselves clarify that the interval of 6 to 8 hours is a population association. That is, it is what works on average for the human species, but it does not imply that this range is the strict and optimal dogma for the biological needs of each individual.

The day Spain wanted to be Spielberg doing science fiction. It was such nonsense that Tarantino ended up claiming the film

by

In 1982, during the filming of Fitzcarraldo In the Amazon jungle, Werner Herzog heard a completely real proposal from several local indigenous people: they offered to kill Klaus Kinski to put an end to the problems he was causing on set. The German director rejected the idea, but years later he would admit that for a few seconds he seriously considered accepting the offer. The impossible movie. In the mid-80s, Spanish cinema was still very far from Hollywood. Science fiction blockbusters seemed to be the exclusive territory of Spielberg, George Lucas or Ridley Scott, while comedies and much more modest films in terms of media predominated here. Then the director Fernando Colomo appeared and decided do exactly the opposite of what seemed sensible: raising a medieval science fiction epic with aliens, castles, special effects, international stars and the largest budget in the history of Spanish cinema up to that point. The result was so enormous, chaotic and Martian that it ended up becoming a symbol first of absolute failure…and decades later in a cult film claimed even by Quentin Tarantino himself. movie poster Spain in Hollywood style. The dragon knight was born as a completely improbable idea: mixing the myth of Sant Jordi with Encounters in the third phasemedieval fantasy, absurd humor and romantic science fiction. The story began with a spaceship mistaken for a dragon in the middle of medieval Europe and a silent alien (played by Miguel Bosé) falling in love with a princess after accidentally kidnapping her. Colomo came from triumph with the comedies of the Madrid Movida, but decided to launch into a gigantic project by Spanish standards. The budget is over exceeding 300 million of pesetas, a crazy figure for the time. Huge sets were built, models and storyboards that were unusual in Spain were designed, and some of them were experimented with. the first digital effects of national cinema. The problem is that Spanish cinema in 1985 simply did not yet have the necessary industrial infrastructure to build something like that without everything exploding into the air. Martian Bosé, Keitel sunk and Kinski unleashed. The casting seemed like an international frenzy. Harvey Keitel accepted the project at one of the lowest moments of his career after working with Scorsese. Miguel Bosé finished turned into an alien because Imanol Arias “did not have the face of an alien,” according to Colomo himself. And then there was Klaus Kinski. The German actor arrived at the filming as a ticking bomb human. He constantly insulted the team, shouted “What a shitty movie!” During the days, he demanded more money, disappeared when he wanted and turned any technical delay into an attack of fury. Apparently, he only respected Miguel Bosé (and for being Picasso’s godson) and the gypsy animal caretakers on the set. To give us an idea, Keitel even offered to pay out of pocket to settle one of Kinski’s contractual tantrums. The atmosphere was so unbearable that Colomo tried to film all the German scenes before meals so I can have a quiet lunch without him. History left the moment when Kinski finally finished his sequences and left the shoot, when the team celebrated his departure. opening bottles of champagne All wrong. The film was shot amidst constant rain, delays, cost overruns and situations almost surreal. An extra was about to drown during a sequence on a lake because the armor was too heavy and he couldn’t stay afloat. An electrician managed to rescue him at the last moment and then used that anecdote for years to demand work in new Colomo films. Not only that. The castle where they were filming was so poorly located that the crew had to upload loading material on exhausting days every morning. Miguel Bose I could barely breathe inside his spacesuit and diving suit it continually fogged up. Meanwhile, money was disappearing at breakneck speed. What had started as an ambitious fantasy ended up becoming something of a kind. suicide expedition where every day seemed to bring a new logistical disaster. The final failure. When The dragon knight It hit theaters in 1985, the reaction was brutal. Part of the criticism destroyed her describing it as a botched, absurd and inoperative fantasy. Although the film was relatively seen and became the seventh highest-grossing Spanish production of the year, that it wasn’t enough to recover such a crazy budget. To make matters worse, the American distributor broke agreements due to delays in the delivery of the material and Colomo lost a trial in Hollywood that left him without international rights. The director finished in debt with 50 million of the old pesetas and, according to would count Years later, he only kept “a Renault 5.” The experience was so traumatic that he thought he was going to have a heart attack. In fact, to survive financially he wrote almost as an emergency The joyful lifewhose subsequent success allowed him to pay off the debts accumulated by that medieval space madness. From disaster to cult movie. For decades, The Dragon Knight was remembered as one of the big hits of Spanish cinema. But over time something began to happen that has been repeated in many other celluloid productions: many people began to see it with fascination. Its impossible mix of genres, its naive tone, its disproportionate ambitions and the chaos that each scene gives off transformed it into a unique rarity. Festivals like CutreCon They claimed it as a cult work and the film ended being restored in 4K forty years after its premiere. The definitive turn came when Colomo remembered a conversation in Sitges with Quentin Tarantino. The American director, always obsessed with strange and failed films, immediately recognized Star Knight (his international title) even before Colomo himself remembered what it was called in English. It turned out that that martian medieval that almost ruined half the world ended up surviving in the most improbable way: converted into a delirious relic of a moment in which Spanish cinema believed, … Read more

the day Naples rejected a Boeing 787 with 200 people on board because it would not enter the airport

by

It hasn’t been long since dawn and the passengers are stretching one day in June 2025 thousands of meters above sea level. They left Philadelphia last night and are about to land in Naples. They are about to discover that, whether they slept better or worse, they are going to have a bad awakening. And when they approach eight hours into the trip and already see the Italian coast on the screens in their seats, a voice informs them that they will not land in Naples. There is not much to fear, everything is in order. All. Except for a small bureaucratic error that is currently diverting them to Rome. They will probably find out about that later. All they know is that their flight from Philadelphia to Naples has had to be diverted. And this time it was not due to a breakdown, a storm or a health emergency. The reason is simple: the plane is too big to land in Naples. Two meters, specifically. Two meters that no one noticed The Philadelphia-Naples route operated by American Airlines is a very good option if you want to travel from the United States to Italy and do not have the need to go through the large airports of New York or Rome. It also has the advantage that it flies at night, which makes it easier to deal with jet lag. Encouragement that, surely, was appreciated by the 231 passengers who had to travel on a Boeing 787-8, according to C.B.S.. However, that day, the airline could have put someone else on board. And, for operational reasons, American Airlines used a Boeing 787-9 On that trip June 3, 2025, a plane slightly larger and with greater capacity than usual on a route that It has been operating since 2024. The aircraft are almost carbon copies. Of course, a Boeing 787-8 measures 57 meters long but the 787-9 already extends to 63 meters long. A difference that has implications beyond the number of passengers. And, according to air safety regulations, a Boeing 787-8 can land in RFFS Category 8 airports (Rescue and Fire Fighting Services) or higher. But a Boeing 787-9 does not have it so easy, it needs to do it at airports in Category 9 RFFS. The difference is small but it is substantial. A Category 8 RFFS airport can accommodate aircraft up to 61 meters long. Yes, two meters shorter than the Boeing 787-9. And you can imagine what category Naples airport has. Indeed, about 70 miles awaythe American Airlines flight asks for a runway in Naples but from the control tower someone realizes the problem: the aircraft is not the same as always. For logistical reasons, the airline was using this second, larger version of the Boeing 787 and therefore exceeded the maximum permitted limit of 61 meters. No one in the company updated the documentation or notified of the change. Technically the problem is not in the size of the trackthe problem is in the security measures. And Naples is not prepared to deal with a possible incident involving a plane of this size. Airport categories are not only classified based on the size of the runway, but also take into account their ability to accommodate emergency and firefighting services. From the control tower they see it clearly, there is no choice but to warn the pilots: they must land in Roma Fuimicino. The capital’s airport is the closest airfield where flights the size of a Boeing 787-9 can land and is therefore where the passengers were ultimately taken. From there, they were finally transferred by bus to Naples, a trip that takes between two and three hours. A lesser evil for a problem that would have been much more serious if the aircraft had had a problem when landing.

His parents built the Chinese economic miracle by working 12 hours a day. Their children have decided not to work almost at all

by

Working twelve hours a day, six days a week, was common in Chinese companies, especially in the technology sector. It is what is known as day 996 and fortunately, the government banned it in 2021. They did not expect that that same year a new concept called Tang Ping and it means just the opposite: doing the minimum to survive. Lay down on the couch. Its literal translation is ‘lie flat’, but we like the creative translation better. Tang Ping It is a social phenomenon that arises as a rejection of the culture of overwork and endless days that barely leave time to sleep. A person who follows a lifestyle Tang Ping He works the minimum necessary to survive and does not have great ambitions; He doesn’t want to buy a car or a house, he spends little on food and he doesn’t want to get married or have children. The latter has not been any fun in Beijing. National security concern. We have talked about the birth rate crisis that China is going through and how the government is doing literally everything for get young people married and have children, so this movement goes against everything they are promoting. The government’s discourse on this trend has taken on a more severe tone. Last April, They published an official warning in which they stated that it is an “ideological infiltration” financed by “hostile anti-China forces” with the aim of “eroding the minds of Chinese youth.” They have turned a lifestyle into a political act that must be repressed. The safety net. They count in Baiguan News that, to understand the rise of this trend, two social mechanisms must be understood. The first is that the parents of these young people were born in the 60s and 70s, so their professional career grew along with the economic development of the country and they are currently the richest demographic group in the country. This means that if their children have financial problems, they can provide support. The second factor is deflation, which is making everything cheaper. In China it is possible to eat for just 1 or 2 dollars in exchange, which makes it viable to live while spending very little money. If we add that youth unemployment is at 16.9% and job opportunities are shrinking, it is the perfect breeding ground for lying down. The generational contrast. The parents of these young people grew up in poverty and, if they worked 72 hours a week, it was not out of pleasure, but out of pure necessity and fear of continuing to be poor. That fear was the engine of Chinese economic growth and allowed the next generation to grow in the abundance that their parents built. The difference is that these young people do not feel that raising the country depends on them, nor do they feel the fear that drove their parents, and many have decided to put their well-being before their professional career.

wants to eliminate the limit of eight-hour days a day

by

The working day in much of Europe has been established for more than a century with a maximum limit of eight hours a day. This limit represents the maximum number of hours an employee can work per day. However, Germany is about to change that scale to make it more flexible and eliminate the daily work day as a metric in the work organization to establish the weekly schedule. As and as I advanced the german newspaper Weltthe bill will reach the Bundestag in June 2026. The idea is not that the Germans work more hours in total, but rather making the working day more flexible so that those hours can be distributed differently throughout the week. Count hours by weeks, not days. What the government proposes is seemingly simple: that the legal reference ceases to be the eight hours a day and becomes the 48 hours per week established by its legislation. With this change, it would no longer matter how many hours are worked each day, but rather that the total number of hours worked throughout the week does not exceed the legal maximum allowed. In this way, an employee could work more hours one day in exchange for working less on another, or concentrate all the load on the first days of the week and spare the rest. The government presents it as a measure to make the working day more flexible and facilitate family conciliation, especially for employees with children. Furthermore, this change would give carte blanche to companies to reinforce the hours on those days with more demand, and reduce (or close) their activity when the workload decreases. What German law says about it. In its article 3, the Arbeitszeitgesetz (Working Day Law) establishes that no employee can work more than eight hours a day as a general rule, with an exception of up to ten hours on specific days, as long as the average of the last six months does not exceed eight hours a day. The maximum limit for the weekly working day, including overtime, is 48 hours. However, the law also sets other limits that indirectly condition the daily work day. For example, you establish that between two work days, there must be at least 11 hours of rest and, if more than nine hours are worked in a row, the worker has the right to an additional minimum break of 45 minutes. These rules are not negotiable by collective agreement and apply without exception to all sectors. They are, precisely, the ones that the government wants to touch with the reform. why now. The definitive impetus for this reform came with the sentence of the Court of Justice of the EU of 2019 and is supported by the European Working Time Directive (2003/88/EC) imposed by the EU, which imposes the maximum weekly limit at 48 hours, and obliges all European employers to record the daily working hours of their employees. Germany, which until now did not require such registration in general, has to adapt to this obligation. The Minister of Labor, Bärbel Bas (SPD), has included electronic time registration in your project precisely as a safeguard. Without this control, Bas warns, flexibility can become a mechanism of exploitation in sectors with little union representation, such as last-mile delivery and parcel delivery. It is an implicit recognition that the standard, on its own, is not enough to protect those who work in more vulnerable environments. What unions and experts say. According what was published by the German media Handelsblatt, The German Trade Union Confederation (DGB) has been the first union platform to oppose the reform. Its president, Yasmin Fahimi, declared that “We are seeing attempts to question the eight-hour work day or to undermine social security systems. Don’t touch the eight-hour work day.” The unions assure that, without a daily limit, workers without a strong collective agreement are exposed to increasingly longer hours without any legal barrier to prevent it. For unions, real protection is not in the weekly total but in control of what happens each day. That is where the limitation of eight hours a day had its strength. The labor law experts of the Hans Böckler Foundation have calculated how much could be worked in the most extreme scenario allowed by European regulations: 73.5 hours per week. A theoretical figure, but possible if there is no daily limit to stop it. Several studies on occupational health document that long hours sustained over time are associated with a greater risk of errors, accumulated fatigue and decreased productivity, effects that the reform does not contemplate.

How much coffee can you drink a day? Science has a very clear limit to avoid its harmful effects

by

For many of us, the starter motor in the morning It has a dark color and a roasted aroma that characterize coffee so much. A drink that is one of the most consumed in the world, but with a popularity that has been accompanied by alarmist headlines about how bad it is to ingest it and the effects it can have directly on the organs. But the truth is that there are lights and shadows. There is good news. For those who love coffee, it will undoubtedly be a relief to know that the literature indicates that consumption is not as catastrophic as they want to sell. But, as in everything, excesses of something can always lead to problems, even if it may seem like something super healthy, such as water. And coffee, obviously, is not exempt. The limit. When it comes to establishing a red line for safe consumption, the clinical reference is not in the WHO, but in the FDA and the EFSAwhich are the food safety regulatory agencies in the United States and Europe, respectively. Here both point to the same figure in coffee consumption: 400 milligrams of caffeine per day. A very relevant figure, since for the vast majority of healthy adults, consuming up to 400 mg daily is not associated with harmful health effectshighlighting that this amount can be part of a perfectly healthy diet and lifestyle. How many coffees is this equivalent to? This is where things get complicated since talking about “cups” is an analytical error, because not all coffees are the same. That is why for the FDA a 355 ml cup, which is a standard size, can contain between 113 and 247 mg of caffeine. But all this depends on the type of preparation, the extraction time or the coffee used, because Robusta coffee has more caffeine than Arabica, for example. But generally speaking, that 400 mg is equivalent to about 3 or 4 cups of standard filter coffee per day. Organic damage. It is easy to see different alarming messages warning that coffee can damage our entire interior if a specific dose is exceeded. But the reality is that the WHO does not send this message to society, since it is too alarming and does not correspond at all to reality. What is true is that excessive daily coffee consumption has important effects on our body, but it will not ‘rot’ our internal organs. Among these stand out insomnia, nervousness, irritability, palpitations, muscle tremors, intestinal irritation, headache… This means that, although we talk about coffee not being contradictory for the population, logically, if there is an underlying problem, it may be better not to drink it, and even less so if it is taken in great excess throughout the day. It has benefits. On other occasions we have talked about coffee and its benefits, because it has more than just keeping us awake in the morning. Here different studies have already pointed out to us the cardiovascular benefits it can have or even improves sports performance. But the metabolism of each person is quite involved here, since there is no single metabolism. In this case, there are people who process caffeine very quickly and its effect disappears quickly, but there are other cases where they metabolize it slowly, so its effects remain in the body and they may, for example, have more problems with insomnia, nervousness or palpitations because they are more “sensitive” to caffeine. This is the explanation, for example, that a person can boast of having a coffee at night and being able to sleep perfectly. There are exceptions. Although we talk about a limit of 400 mg of caffeine, there are people who logically cannot reach this limit, such as pregnant women, where a maximum of 200 mg per day is recommended, since excess caffeine can cross the placenta and affect fetal development. But it also influences, for example, the cholesterol level, since here the Mayo Clinic points out that the consumption of unfiltered coffee, such as Turkish coffee, can raise cholesterol levels due to compounds such as cafestol.

The day a small dispute over the Tab key ended up revealing the big difference between IBM and Microsoft

by

There are companies that have lived so long that their story is no longer told only through big launches, acquisitions or business battles. It is also told in small details, in those seemingly minor scenes that, seen over time, end up explaining an era better than many official statements. Microsoft and IBM belong to that category. Their paths crossed when the personal computer It was still defining many of its rules, and some of those discussions, even the most minute ones, revealed something deeper than a technical difference. The scene has been recovered Raymond Chena veteran Microsoft engineer who has been linked to the evolution of Windows for more than three decades and who for years has gathered in The Old New Thing some of the most curious stories of the Windows and Microsoft ecosystem. Chen does not present the episode as his own experience, but as the memory of a colleague who was assigned to the IBM offices in Boca Raton, Florida, during the collaboration between both companies in OS/2. OS/2 was much more than just another name lost in software history. IBM and Microsoft presented it in 1987 as an operating system designed for the IBM PS/2 line and intended to take the PC beyond the limitations of DOS, with a more modern base and ambitions typical of computing that was beginning to look further afield. The collaboration came from a joint development agreement signed in 1985when the project was not yet called OS/2. In that context, any interface decision could have more weight than it seems today, because many conventions of the modern PC were still being established. Two very similar and also very different companies The problem is that that collaboration brought together two companies at very different times in their lives. Microsoft was still a young company, very attached to software and a more direct way of working, while IBM arrived with decades of history, a huge structure and the weight of a much more established corporate culture. Chen sums it up like a clash of perceptions: from Microsoft, IBM was seen as trapped in a meaningless bureaucracy, and from IBM, Microsoft was seen as undisciplined hackers. Its own nuance is important: there was probably something right in both readings. The specific anecdote begins in Boca Raton, where a colleague of Chen’s worked assigned to the IBM offices. At some point a discussion arose about which key should be used to move from one field to another within the dialog boxes. The Microsoft engineer made a decision that is almost invisible to us today because of how assumed it is: use Tab for that function. IBM was not convinced by the choice and asked that the matter will be escalated to the person responsible from that engineer in Redmond, a reaction that already hinted at the extent to which the discrepancy went beyond the key itself. In Redmond, the petition was not understood as an issue that deserved to be raised much higher. The engineer’s manager responded with a very clear idea: if Microsoft had sent someone to Boca Raton, it was so that they could resolve decisions like that there. Translated into a more institutional tone, the message that came back to IBM was that Microsoft supported the choice of the Tab key. IBM’s reaction was just the opposite. Instead of shutting down the discussion, the company elevated her up its own chain of command to a vice president, several levels above those who were programming. IBM had not only elevated the discussion, it also wanted a response to the same hierarchical height. If its vice president was against using Tab, Microsoft had to find someone equivalent to argue the opposite. Chen’s colleague then responded with a wonderful phrase, translated here into Spanish: “Bill Gates’ mother is not interested in the Tab key“It was a pretty nice way of saying that it wasn’t worth going up the corporate elevator anymore. It wasn’t necessary to go to the heights of Microsoft to decide how to move from one field to another in a dialog box. The phrase worked, at least according to Chen’s account: apparently, after that response, the discussion ended and Tab remained the key chosen to advance between fields. The detail is funny because today almost no one stops to think about it: we simply press Tab and wait for the cursor to jump to the next available space. But there was a time when that convention was not so closed. And what we see in this story is just that: a small interface decision turned into a clash between custom, hierarchy and technical criteria. The exact date, however, does not appear in Chen’s account. We know that the episode belongs to the years of collaboration between Microsoft and IBM around OS/2, whose joint development agreement dates back to 1985 and whose Public arrival occurred in 1987. This allows us to limit the context, but not to set the day or year of the discussion by Tab. There are many decisions behind the products and services we use every day. Some are huge and visible, but others fly under the radar: a key, a gesture, an interface convention that we learn once and repeat for years without wondering where it came from. Surely many have a story behind them, although most never transcend and others would not be particularly interesting. From time to time, however, an anecdote like this appears and allows us to peek into something we almost never see: how things are handled within the companies that build the technology we use.

How Much Protein You Really Need per Day and What Science Says About Supplements to Reach Your Goals

by

In the sports world there is a great debate about how much protein should be consumed daily in order to have a good result in the gym and for the muscles to grow. But the truth is that sometimes the figures you hear about the doses you need to take are very high, and that is why it is best to go to the official source where they tell us the most appropriate doses for each person. We are not all the same. The biggest mistake when talking about protein is thinking that there is a universal figure, since recommendations vary drastically depending on whether you spend the day sitting in front of the computer or if you strength train four days a week. This is why authorities have historically established a minimum protein intake to avoid health problems, and not to optimize performance or body composition. The general population. Here the WHO it’s pretty clear pointing out that the minimum protein that should be taken is 0.75-0.8 grams per kilo of weight per day. But we talk about “minimum” and that means that it is not necessarily optimal, and that is why other guides raise this range to 0.8-1 grams per kilo of weight, emphasizing the need to include a source of protein in each meal. In athletes. Things change in this context, since the International Society of Sports Nutrition point Because, if you exercise, you should take between 1.4 and 2 grams of protein per kilo of weight per day, reaching peaks of 2.5 grams in very intense training phases. The supplementation. Achieving 2 grams of protein per kilo of weight can be a real logistical (and digestive) challenge based on chicken breast, eggs and legumes. But this is where the famous protein supplementation comes in, which should not be used as a magic remedy, but as a practical, safe and highly bioavailable tool for healthy people who They need extra protein. It is investigated. Here studies highlight that proteins derived from milk are the ones that offer the best results, although vegetable options such as those derived from soy are not far behind. The undisputed queen is wheywhose main advantage is its rapid absorption and high bioavailability, something that has been seen in clinical trials where greater development of strength and lean mass after exercise was evident. Another of the great supplements is casein, which is the slow-digesting protein, with an “anti-catabolic” effect that prevents prolonged muscle breakdown. In this way, experts point out that it is ideal to take it before sleeping to ensure a constant drip of amino acids during the night, which are nothing more than the bricks that will form the muscles.
