Those who played in the street until nightfall gained a skill that we have lost today

In 1971, a pioneering study from the psychologist Roger Hart He asked dozens of children to draw a map of places where they could move alone. What he discovered It was surprising: Some traveled several kilometers without adult supervision and knew their neighborhood like the back of their hand. Decades later, Hart repeated the exercise and found that this “territory of freedom” had been drastically reduced, a trend that has since been observed in numerous countries. A value that many of us considered lost. For years, playing in the street until nightfall was remembered above all as an image loaded with nostalgia. However, a number growing research is coming to a conclusion much more interesting: that everyday freedom was also an unparalleled psychological training. Yes, resolving conflicts without adults, exploring the neighborhood, taking small risks or even inventing games on the fly thanks to “boredom” helped develop skills like autonomy, trust, emotional regulation and the ability to face uncertainty, skills that many experts today consider less and less frequent among the children. It’s not the parks, it’s the size of the world. Researchers use a very graphic concept to measure this transformation: the home rangethe territory that a child can walk without supervision. I remembered the Washington Post that just a few generations ago the baby could cover several kilometers. Today, in many cases, it barely reaches the door of the house. In fact, studies carried out in different countries show that less and less minors can go to school alone, cross a main street or visit a friend in the neighborhood without permission or constant supervision of an adult, a reduced independence that reflects the extent to which childhood has changed. Playing was not a waste of time. When a group of children were discussing the rules of a game, deciding who started, or finding a solution to recover a lost ball, they were doing much more than entertainment. The researchers they count that, without realizing it, negotiation, cooperation, creativity, frustration tolerance and decision making were practiced. Precisely for that reason, a study A recent study by Aarhus University concluded that children themselves consider it essential that the game belongs to them and not to adults, to the point that one of its authors summed up the idea with a phrase as provocative as it is revealing: “Sometimes an adult should shut up and go away.” Small risks also educate. Falling off a bicycle, climbing a tree or returning home with scraped knees are part of common memories for several generations. Nowadays, these episodes are usually interpreted as situations that should be avoided, but many psychologists hold that these controlled risks teach something difficult to acquire in any other way: evaluate dangers, overcome fear and verify that problems usually have a solution. In fact, various scientific works they point Even this gradual exposure to uncertainty can strengthen self-confidence and reduce the risk of anxiety in the long term. The data that proves it right. Nostalgia may idealize the past, but scientific evidence is beginning to support some of that perception. a study of the University of Exeter with more than 4,000 children concluded that those who played outdoors more frequently between the ages of two and four were more likely to maintain a good mental health profile up to eight years. Not only that. Other research with 2,500 minors found that outside play was associated with better social and emotional skills, reinforcing the idea that these benefits go far beyond physical exercise. It’s not the screens, but what they have replaced. In what they insist experts is that the decline in outdoor play cannot be explained by technology alone. Traffic, the disappearance of safe spaces, the reduction of recreation time, parental fear and a culture that tends to supervise any children’s activity also play a role. The result is a childhood much more organizedwith more guided activities and fewer opportunities to experiment, make mistakes and learn on your own. The great paradox. Of course, no researcher proposes returning to a time with fewer security measures or letting children do anything. The debate revolves around another question: strike a balance between protecting and allowing them to develop their own autonomy. After decades trying to eliminate any risk from childhood, psychology is beginning to remember an idea that many generations learned by playing in the street until nightfall: confidence does not usually appear when everything is under control, but when someone discovers that they are capable to get ahead on your own.

There is a way to preserve zucchini for weeks and months. And with a little skill and attention, it is within everyone’s reach.

There is a scene as universal in these months as that of the blade fan: something clicks and three bags of zucchini appear at the door, in the kitchen or already in the refrigerator. And right in front of them, there is always the same face of “and now what do I do with all this?” The answer is simple and, at the same time, really complex. First because, if we want to preserve it long enough to be able to use it, we have to differentiate between what lasts fresh and what lasts after being transformed. And second, because If we don’t do it well, that transformation we are turning that zucchini into a “poisoned gift.” And never better said. A zucchini is water with some form. To be exact, 94.8 out of every 100 grams of zucchini are water. This vegetable has only 17 kilocalories, extremely thin skin and, in short, no fat to protect it: it has a delicious design to eat, but terrible to preserve. In its optimal state it lasts a week in the refrigerator; two or three if we are willing to live with their ailments. And then? Where do the ‘months’ come from? As I hinted above, they come out of ‘processing’ it. You can reach months in a simple way: freezing them (after blanching for three minutes and an ice bath), dehydrating them either pickling them. That is, it can last up to ten months in good conditions if it is no longer fresh zucchini. Until a few years ago it was relatively common to put zucchini in a jar and cook them in a water bath until it reached a sufficient temperature to preserve it well. The problem is that zucchini is low in acidity, its pulp becomes soft and compact, and it transmits heat poorly. Come on, it becomes a fantastic remedy for botulism as long as we make the slightest mistake. Agencies strongly recommend against doing so. And how do we do it well? Let’s go in parts: Fresh and whole: directly to the refrigerator without washing. If they are dirty, it is better to clean them with kitchen paper or a dry cloth. If you have to give them a little water, dry them well. There is little else you can do: don’t crowd them, use special pads and avoid putting them next to climacteric fruits and vegetables (apples, avocados, mangoes or tomatoes). Cut: If we want to keep it already cut, we just have to keep in mind that the more processed it is, the less it will last. The ideal is to cut it, dry the vegetable well with kitchen paper and put it in an airtight container. It is not advisable to keep it like this for more than three or four days. Cooked: in this, the truth is, there is no big difference with the rest of the vegetables. A well-cooked zucchini dish can be stored without problems for about five days. The key is, of course, to refrigerate it as soon as possible, close it tightly and divide it into the smallest portions possible. It can also be frozen. What if we haven’t cooked it previously? What I explained above: freezing them, dehydrating them either pickling them. They are more complex preparations, but if we have many… it is the most recommended.

“It’s like acquiring a new skill”

A video from the Ukrainian unit Signum showed in 2022 one of the first successful attacks with improvised FPV drones against Russian positions, a scene that many analysts consider the starting point of the tactical revolution that today armies from half the world study. That started as a homemade solution of volunteers and hobbyists. Four years later, countries like Taiwan are teaching their citizens to fly them as part of their defense. The Ukrainian lesson. The war in Ukraine has changed many things, but one of the most profound has been the way in which the drone has stopped being an auxiliary tool and has become in a centerpiece of modern combat. Thousands of daily missions, cheap precision strikes and a constant ability to monitor, correct fire and wear down the enemy have transformed the logic from the battlefield. In Taiwan, this reality is observed carefully because the conclusion is evident: if Ukraine has managed to resist a superior power for years thanks, in part, to democratizing drone warfare, the island believes that must learn that lesson before it’s too late. Convert civilians into operators. That is why Taipei has launched its first civil drone piloting training program, an initiative promoted by Kuma Academy that seeks to teach ordinary citizens something that a few years ago seemed reserved for the military or advanced amateurs. The Guardian said that, in a small room full of cones, young people, retirees and workers practice basic flights, control maneuvers and visual navigation. The important thing is not only to learn to fly, but to assume that this knowledge can have real strategic value. One of the participants summarizes it with a phrase which encapsulates the entire philosophy of the program: “It’s like giving me a new skill, something I could use one day if I needed to.” The drone as a citizen weapon. That is the most profound change: in Taiwan the drone is beginning to be seen as a species civic weaponnot necessarily offensive, but useful to survive and contribute in a crisis. The idea is not to arm the population, but to move it from a passive defense (hide and wait) to an active defense based on observing, detecting and sharing information. on a stage Chinese invasionthese small devices could be used to monitor enemy movements, locate wounded, coordinate evacuations or maintain visual links in areas where traditional communications fail. The logic is simple: not everyone can hold a rifle, but almost anyone can. learn to fly a drone. Prepare for China. There is no doubt, the backdrop is the increasing pressure from China on the island. Taiwan lives under constant threat of a possible Chinese military operation and more and more citizens seem to assume that individual preparation is part of national defense. The expansion of civil defense groupsfirst aid courses and now drone literacy They are part of that social transformation. From that perspective, preparation is no longer just a matter of the army, each citizen becomes a possible piece within a broader resistance network. Learn to fly without automation. The technical detail of these courses says a lot about how Taiwan understands future warfare: the drones are small, light, domestically manufactured and without GPS or autopilot. The reason is crystal clear. In a modern conflict, electronic warfare can disable automatic systems in seconds, so the pilot must learn to control the machine by pure sight and reflections. It is modeled on what happens in Ukraine, where the electromagnetic combat It forces you to constantly improvise and adapt. Taiwan does not want to train users of convenient technology, it wants to train operators capable of continuing to function when technology fails. Strategic autonomy. This effort also fits with another objective: reducing the technological dependence from China and build its own supply chain for drones. Taiwan manufactures part of their weaponsbut it still depends arms sales of the United States for its heavier systems. Furthermore, political uncertainty in Washington and the ups and downs in the relationship with Beijing reinforce the feeling of vulnerability. For all these reasons, for many Taiwanese, learning to fly a drone is no longer a hobby or a technical curiosity. It is more of a tangible form to prepare for an uncertain future, with the conviction that, if the worst scenario comes, every skill acquired today can make a difference in the future.

College students are rapidly losing a critical skill: reading.

My students can’t read. It is the title of the opinion column in which Tyler Jagtuniversity literature professor, narrates the situation currently found in his classrooms. Many students are not able to read or maintain the plot of a 20-page text. He believes that AI and mobile phones are to blame. 20 pages is too much. This teacher says that he has been assigning the same task to his rhetoric and writing students for five years: reading a 20-page article. However, this year none of his students finished the work and they were not repeaters, but rather university students who had passed the entrance exams. One of them was honest and admitted that the text was too long and “constantly missed the point of the article.” Jagt acknowledges that the complaint that students do not know how to read is common among teachers, but according to him this time things are serious and there is data that corroborates it. The tests. According to the results of the 2024 National Assessment of Educational Progress (NAEP), students in grade 12 (equivalent to a 2nd year of Baccalaureate in Spain) obtained the lowest score on the reading test since the assessment began in 1992. A third of the participants reached the basic level, which means that they are likely not able to “draw general conclusions based on concepts explicitly presented in a text.” Younger students are even worse off. According to a study by the Annie E. Casey Foundation70% of fourth grade students (like fourth grade) are not able to read fluently. That is in the United States, but in Spain the situation is not ideal either. According to the OECDat least a third of the Spanish population has level 1 reading comprehension, which means that “they can only understand very short texts with a minimum of distracting information.” A report from the BBVA Foundation and the Valencian Institute of Economic Research (Ivie)Spaniards between 25 and 34 years old, who have studied more than their parents, advance much more slowly in basic skills. It’s technology’s fault. Or at least that is what the author maintains, specifically the emergence of smartphones and, more recently, AI. The idea that technology makes us stupid has been accompanying us for decades and with the emergence of AI, technological panic has intensified. That students are using AI to do their jobs is something we already knew. What is still not clear is what consequences it can have on a cognitive level. There is no evidence that technology produces cognitive damage (yes changes), but it is also true that until now we have not had a technology capable of doing everything that AI does. Debt and cognitive surrender. They are two concepts that emerged from recent studies. The first, cognitive debtcomes from a MIT research titled “Your brain on ChatGPT”. Participants who used ChatGPT had the worst brain performance when completing a task that involved writing essays. The researchers conclude that using AI as a complete substitute for mental effort can weaken our neural connections. The idea of cognitive surrender is mentioned in a recent study from the University of Pennsylvania. According to researchers, cognitive surrender arises when we delegate our thinking to AI and accept its answers too confidently. Another study from the University of Oxford saw how If we use AI and then it is taken away from us, our performance worsens. not so fast. There is an important nuance and that is that the concept of “using AI” is very varied. We can use it without checking the answers and accepting everything it tells us or we can use it as a tool in our creative process. In fact, in several of these studies, participants who used AI as support obtained scores very similar to those of the group that did not use AI. Therefore it is not whether we use it or not, it is how we use it. However, the arguments in favor of using AI in educational environments are becoming fewer and fewer. There was a study that said using chatbots like ChatGPT had a positive impact on learning, but was recently withdrawn due to “concerns regarding discrepancies”. Come on, the biggest argument of the defenders of educational AI went down the drain. The other culprit. As we said, this professor also points to smartphones as responsible for this situation. Appointment a 2017 study in which they verified how the simple presence of the mobile phone reduced the “available cognitive capacity”. He also cites another 2022 study in which they saw that reading on a smartphone was associated with prefrontal overload and decreased concentration. Tiktokize the school. The problem is not cell phones, but social networks and doomscrolling that hijacks our attention. We have become accustomed to consuming pills of information in the form of tweets, posts, reels and tiktoks. In this context, a 20-page text is much, much. Tyler Jagt is adapting to this reality by dividing work into two, so they have to read less, and assigning specific tasks so they don’t lose track as much.
