In 2019 we discovered fungi that metabolize gold. There are already those who want to turn them into the key to space mining

by

The story started more than five years ago in Boddington, south of the Australian city of Perth. Over there, among killer animals and gold mines, a team of researchers from the Australian CSIRO discovered something really strange: that certain strains of the fungus Fusarium oxysporum Not only could they extract gold from their surroundings and integrate it into their structure, but by doing so they managed to spread faster than the rest. It seemed like a curiosity, but in recent years the situation has begun to change. But wait, why is this something so “weird”? Good question. After all, we know for a fact that fungi “play an essential role in the degradation and recycling of all types of organic material (like leaves or bark), but also in the cycle of certain metals such as aluminum, iron, manganese and calcium.” Why would it be different with gold? Because, as Tsing Bohu, researcher in charge of the project, explained, “gold is so inactive (chemically speaking) that these types of interactions are unusual and surprising, I had to see it to believe it.” And he saw it. In fact, it published in Nature Communications. It was the first solid evidence that fungi could play a relevant role in the gold cycle in the Earth’s crust. The “mushroom” of the golden eggs. The mining industry quickly turned its attention to the investigation. Especially right there in Australia. The island continent is the world’s third largest gold producer, but the consensus among analysts was that without new deposits production was going to fall (a lot) in a short time. The direct consequence is that this has made marginal deposits profitable. Initially, the industry thought that the CSIRO investigation could be used to locate these new deposits. As we explained years agoIn Australia it is relatively common to prospect in forests of the aucalyptus family or near termite areas because they have a close relationship with the precious metal. Why not test the soil for those strains of Fusarium oxysporum? But there is one more possibility. As Eduardo Bazo explained to Eugenio Fernández in a very interesting interviewin recent years companies have appeared that work in what we could call “metabolic mining“That is, using organisms to extract gold. “And why do they want that?”, you might ask. “Isn’t it easier to identify where the gold is and extract it with industrial methods?” Yes, here on Earth, yes. But these companies have their sights set a little further: on space mining. For years we have talked about the existence of huge mineral deposits in the Solar System and, during almost the same period, we have fantasized about being able to exploit them. The problem is that, beyond current technological limitationss, to the danger of normal mining, is added the fact that we are talking about processing metal in space. But what if we use ‘metabolic mining’? The idea of ​​sending modified strains of these fungi (or other types of microorganisms) that They will process the mineral for useverything would become simpler. I don’t know if it’s more viable, but it is simpler. It is much less rare than it seems (we use this type of approach to countless products we use regularly), however taking it to the world of mining seems a little more complex for pure efficiency. However, that is ‘now’. Because there are already experiments in this sense generating platinum in microgravity conditions and ‘metabolic’ copper is moving a lot of money. What’s more, while I write (and while the era of cheap materials is over) several research groups They are growing all kinds of microorganisms with the idea of ​​being able to grow gold sooner rather than later. They are getting it. Image | Dominic Vanyi | Jaap Straydo In Xataka | The next richest person in the world will come from space: the future millionaire of space mining

If you are looking where to see the astronomical phenomenon of the yearin Xataka have the definitive solar eclipse map. In it, you can check the percentage of the Sun that will be hidden by the Moon in your city, but also thoroughly analyze the strip of totality. Are you looking for a mountain place with skies free of light pollution? Do you prefer a small charming town? Do you want to know the exact time at which the solar eclipse will take place at your viewing location? You have everything just a click away. How does the solar eclipse map work? At first glance, our solar eclipse map is similar to most maps of this style that have been published lately. The emphasis is on marking the strip of totality, since inside it are all the locations where the total solar eclipse can be seen. However, in the legend we can mark specific details that may be of interest when observing this type of astronomical phenomena. For example, it is not the same to see the eclipse in a big city as in a small townof even less than 1,000 inhabitants. There are those who prefer the first and those who opt for the second. On the other hand, for this type of activities the ideal is to be located in points with clean skies, as free as possible from light pollution. This is accredited by the starlight certificationsince it is only granted to protected natural spaces committed to the preservation of the night sky and access to starlight. Therefore, on the map we can also see all the points with said certification. On the other hand, it should be noted that the stripe of totality is represented with a purple whose intensity increases directly proportional to the duration of said totality. This eclipse will have its maximum totality in Iceland, where it will slightly exceed 2 minutes. In Spain, however, the longest totality will be 1 minute and 50 secondsin a very small area of ​​Asturias. Other information On the solar eclipse map you can also see the time at which the eclipse will begin and end in each area. In addition, the time at which the Sun will set is included. It is important, because in many cases it will do so while still eclipsed. It is one of the facts that makes this eclipse so special. When it occurs near sunset, the Sun will already be very low and close to the horizon. The lower you go, the clearer the west should be of mountains and buildings. Therefore, the height at which the Sun will be at the peak of the eclipse is also included. This will allow us to better organize our possible observation places. It is always good to think about several options, in case an unexpected cloud ruins the first one for us. In any case, this is still an interactive map, so it is best that you be the one to tinker with all its options. Surely, if you have decided to get on the bandwagon of this eclipse, you will find it very useful.

Brussels is already preparing an emergency team

by

A decision made thousands of kilometers away could end up affecting a European factory that needs chips, magnets or processed materials to maintain its production. That is the fragility that Brussels is trying to reduce as a particularly sensitive date approaches in its trade relationship with China. For years, Europe has built industrial chains that are highly exposed to certain suppliers. Now, when geopolitical tensions interfere with supply, the European Commission is trying to prevent the next crisis from encountering it again by reacting when the problem is already on the table. China concentrates supply: The figures help to understand the dimension of the problem. China represents 66% of all rare earths extracted in the world, but its weight increases to 88% when we talk about refined supply, according to the Financial Times. This second proportion is the most revealing, because having the mineral is not enough if there is a lack of industrial capacity to process it and leave it ready for use. For Europe, dependence does not end at the mine: it continues in the plants that convert these raw materials into products that can be used by their manufacturers. October, the date that worries Brussels: China lifted a one-year ban on some exports of magnets and rare earth raw materials, but that commitment expires in October. European officials remain hopeful that Beijing will extend the truce, although they cannot rule out restrictions returning when the deadline expires. The relief also did not eliminate all controls, because China maintained a licensing system which requires European buyers to submit applications and provide information about their production processes and customers. This uncertainty explains why Brussels prepares responses before learning of the Chinese decision. A team to anticipate the crisis: According to three officials cited by the Financial Times, the Commission is preparing an emergency force whose first meeting is scheduled for September. Brussels wants to bring together those responsible for industry, commerce, financial services, economy and development aid in the same group, together with the central unit under the direct control of Ursula von der Leyen. Your goal will be to identify problems early and coordinate a common response. China will be one of its focuses, but not the only one, since the initiative also aims to respond to other economic and industrial threats. Find suppliers and mobilize European money: The strategy combines two moves. On the one hand, identify alternative suppliers and consider the use of EU funds to help maintain supply if an interruption occurs. On the other hand, change the rules with which the most exposed companies operate through a future diversification law, which would force them to reduce their dependence on a single source for certain key inputs. The Commission does not intend to replace Chinese supply overnight, but rather to better spread a risk that today is excessively concentrated. Nexperia already showed the risk: The closest precedent is not in rare earths, but in semiconductors. Last October, a dispute between the Dutch government and Nexperia’s Chinese owner caused chip supply tensions, to the point that the automobile industry warned of possible shortages. Faced with this pressure, the EU chose to temporarily relax the sanctions applied to another Chinese supplier. The episode showed how high dependency can quickly reduce Brussels’ room for action when the industry begins to run out of alternatives. Brussels is preparing for the worst scenario: The Commission is also working on measures to make better use of the resources available within Europe. The proposal planned for September would include a tax on the export of aluminum scrap, designed to keep more material in the block and encourage its transformation into new metal, according to sources cited by the Financial Times. Actions are also being studied to increase the recycling of rare earth magnets. The logic is simple: importing from more places helps, but recovering more materials within the EU also reduces foreign exposure.

Carnival’s next megacruise will be huge. Your biggest change will be in how the sea will look

by

A mega cruise can offer so many attractions that at times it’s easy to forget you’re sailing. Carnival aims to respond to this contradiction with the Carnival Destinya ship of enormous dimensions whose proposal will not be based solely on volume, capacity or the number of spaces on board. The shipping company wants its distinctive feature to be its relationship with the outside world. To achieve this, it has proposed an open architecture, with more glass surfaces, wide perspectives and areas designed to keep the ocean within the field of vision. Carnival Destiny will be the first member of the new Ace class, a family of three ships with deliveries scheduled for 2029, 2031 and 2033. Its construction formally began with the steel cutting ceremony at the Fincantieri shipyard in Monfalcone, Italy, where a 3D hologram was also shown with the first preview of its design. Delivery is scheduled for summer 2029, after which she will sail to destinations in the Caribbean, Bahamas and Mexico. By size, the Destiny will enter directly into the highest category on the market. Its approximately 230,000 GT of gross tonnage and its capacity to around 8,000 passengers They will place it close to the largest cruise ships built, although it will not lead the classification by volume. Royal Caribbean’s Icon class ships, such as the Icon of the Seas and the most recent Legend of the Seasare around 250,800 GT and can accommodate around 7,600 passengers at full capacity. The new Carnival ship will therefore compete in that same league, but with a different proposal. A giant who does not want to hide the ocean Once its scale is located, the difference that the company wants to highlight appears in the design. Carnival has not yet presented a main attraction or a large thematic space that defines the ship, but rather a different way of organizing it around its relationship with the outside. The company describes it as the most outward-oriented megacruise ship on the market, a promotional claim it will yet have to prove. The intention, in any case, is clear: that the ocean functions as a constant reference and not as a secondary element. To materialize this idea, the project will use more than 18,200 m² of glass surfaces. Among the elements already announced there will be multi-story glass wallsmore open lines of sight and a greater presence of spaces facing the outside. It is not just about adding windows, but rather organizing part of the architecture to reduce visual obstacles and extend views across the ship. Carnival has not yet shown the complete design, so the real scope of that transformation remains to be known. This image shows Royal Caribbean’s Legend of the Seas, not the future Carnival Destiny. Delivered in June 2026 as the third ship of the Icon class, it represents the current reference against which Carnival will place its new giant Another of the pillars will be in the cabins and on the outer decks. The company maintains that the Destiny will have an unprecedented number of accommodations with balconies and sea views, but has not published a figure to verify the scope of that claim. It will also redesign the Lanaian exterior cover designed to create a more continuous connection with the ocean. With this, the shipping company intends that this relationship does not depend solely on the large panoramic spaces. The changes will not end in the architecture, although the rest of the new features are still difficult to measure. According to Carnival, more than 70% of the spaces and attractions will respond to concepts that the brand has not used beforewith proposals planned for restaurants, bars, lounges, entertainment and outdoor areas. The figure is striking, but it is not yet accompanied by names, plans or detailed descriptions. Until these announcements arrive, it can only be stated that it is preparing a broad renewal of its offer, not that each proposal will be unprecedented in the sector. The Destiny proposal is based on a contradiction: the more cruise ships grow and the more activities they concentrate, the easier it is for the sea to be relegated to the background. Carnival will try to correct this with balconies, exterior routes, large glass surfaces and a layout designed to expand the views. The idea has already been defined, but it still remains to be seen how it will work on a ship prepared for around 8,000 passengers. Until 2029 we will not know if this architecture will really change the experience or if its greatest effect will remain in the promotional field.

China has just gathered 100,000 national accelerators into a supercluster. The challenge now is for them to work together efficiently.

by

China has launched in Zhengzhou the Dawning 8000, an artificial intelligence supercluster that, according to Sugon, can integrate 100,000 calculation cards developed in the country. The company presents it as the first Chinese system of this size built around a national infrastructure, from chips and network to storage and cooling. Sugon assures that the project is already connected to the national supercomputing network, although it has not yet published its complete technical specifications. The scale is not enough. The size of the installation does not in itself imply an equivalent leap in computing capacity. In loads that intend to take advantage of thousands of processors, the work must be dividedsynchronize and recompose without communication between nodes ending up consuming a disproportionate part of the time. As the stack grows, so do the points of failure, software complexity, and demands on network and storage. The real challenge begins when those cards have to behave as a single machine. The pending jump. Sugon maintains that the central node has already been optimized for more than 300 applications in about twenty fields, including large models, robotics, automotive, pharmaceutical industry and weather forecasting. The company adds that more than 70 applications have completed deployments at scale of 10,000 cards. These are relevant data to evaluate the maturity of the platform, although the information released does not detail a public load executed with the 100,000 units simultaneously. Autonomy under pressure. Zhengzhou’s bet cannot be separated from the pressure facing the Chinese technology industry. The United States included Sugon in its Entity List in 2019 and has since expanded restrictions on advanced semiconductors and equipment related to high-performance computing. In this scenario, building an infrastructure based on national technology has a value that goes beyond the power achieved. The project fits into China’s effort to expand its own capacity and reduce supply chain dependencies. The figure is not enough. One hundred thousand Chinese accelerators do not automatically equal one hundred thousand comparable Nvidia GPUs. The deployment also does not allow us to affirm that China has left behind its dependence on Western hardware to sustain its artificial intelligence infrastructure. It does demonstrate, according to Sugon, that the country can now build its own systems on an increasingly larger scale. It is not complete autonomy, but it is another step on the path to depending less on foreign suppliers.

What science says about the “trick” of two crossed fans to cool the house: it works, but with limits

by

With heat waves hitting the thermometers, the desperation to cool the house without increasing the electricity bill leads us to look for any shortcut. And although the new air conditioners have shown that they have a low daily costthe reality is that many people prefer to opt for the classic fan and there are ways to optimize its operation. An idea. Something that has become popular in recent days is the possibility of using two fanshaving each in opposite windows. Under this premise, the idea is that one of them brings in air from the street and the other manages to get it out to ensure that the house in the end is as cold as possible within their possibilities. It has support. What is proposed here is to take to the extreme a concept that has been used for a long time in the architectural world to ensure that homes, passively, can acclimatize. And, according to the design standards and manuals of entities such as the IDAE, uwell-designed cross ventilation can reduce the interior temperature by up to 5°C. The two-fan technique falls into the category of hybrid or assisted ventilation. As detailed by platforms specialized in architecture such as ArchDaily or the technical area of ​​Tinsa, it is not enough to open windows at random. For there to be flow, a pressure difference must exist. The idea. By placing one fan pointing inward on the coldest façade, which is normally the north one or the one facing a shady patio, and another pointing outward on the opposite façade, we are mechanically forcing that pressure differential. The goal here is for the cool air to push the stagnant hot air mass out the opposite window. Although yes, for this flow to accelerate and be more efficient, the opening through which the air leaves should be more open than the one through which it enters. It’s proven. A thesis from the Piloto University of Colombia wanted analyze the effectiveness of this ventilation methodand it was seen that this system showed a significant reduction in thermal load in a hot-humid climate. Although here it is important to highlight that the thermal insulation of the home or building is very important, logically, to maintain an adequate temperature. It has small print. Logically, these two fans cannot work miracles, and if the outside temperature exceeds 30 degrees and especially if the relative humidity is high, cross ventilation loses all its effectiveness. Far from cooling, here there would be thermal energy in the home and forcing the entry of air at 35 °C with a fan is the equivalent of turning on a giant hair dryer. The best hour. Here the official recommendations point out that cross, forced or natural ventilation is a strategy that should be left for the first thing in the morning or at night. when the temperature is considerably lower. For the “two fans trick” to work and achieve that promised 5°C drop in the structure of the house, you must apply it only when the outside temperature drops below the inside temperature. This is called “selective ventilation” since during those hours, the mechanical technique of the two fans will sweep away the heat accumulated on the walls and ceilings during the day.

a study shows why it is a trap

by

A common scene in any summer is seeing how people arrive at the beach, stick their umbrella in the sand, spread their towel or put their chair under the shade and breathe a sigh of relief because they think that this way they won’t get burned. The problem comes when you get home and, after taking a shower, you can clearly see how your skin is burned. The culprit. This situation, which is more common than we think, is not the fault of the material the umbrella is made of or even the protection factor assigned to these products, but rather the problem is in the sand itself and the rebound effect that the Sun’s rays have. The experiment. To understand what is happening here, we have to go to a great study published in 2017where researchers took 81 participants with sun-sensitive skin to a sunny Texas beach. They were left in this environment for 3 and a half hours at midday, but with the difference that one group of them only used a standard beach umbrella as protection and another group only used sunscreen with an SPF 100 factor without seeking shade. The results were devastating, since 78% of the participants who were under the umbrella developed sunburn, compared to 25% in the group that used the cream. Although if we look at the total number of injuries, the difference is even more overwhelming, as 142 incidences of sunburn were recorded under the umbrella, compared to only 17 in the sunscreen group. How is it possible? For many people, it makes no sense to burn their skin if they are constantly in the shade, but the answer to this lies in albedo, which is a metric that defines the percentage of radiation that is reflected by a specific surface. And ultraviolet light not only ‘falls’ from the sky in a straight line hitting us, but it also bounces off the ground and impacts from any direction. For example, we know that beach sand reflects between 15% and 20% of the UV radiation it receives, a figure that is much higher than that reflected by asphalt, which is around 2%. Although all of these remain ‘nothing’ if we compare it with snow, which is undoubtedly almost like a mirror, since it reflects a spectacular 85% of ultraviolet rays. You have to combine it. With all this data we should not fall into the thought that the umbrella is completely useless, but we should be aware of the importance of using sunscreen as soon as we leave home to prevent this radiation from affecting our skin. And logically, also combine it with the umbrella on the beach to achieve these two protection systems. It’s not just the beach. It is increasingly common to see people on the street who are walking with their umbrellabut here you are not exempt from suffering some burns because, as we have seen, even asphalt can reflect ultraviolet radiation. That is why sunscreen is not only an item that should be used when we go to the beach or pool, but in any situation where the UV index is high.

Anya Taylor-Joy is a lucky con artist in one of this week’s most intriguing premieres, now streaming

by

Apple TV+ premieres today the first two episodes of ‘Lucky‘, a series with a few stars in the cast and that is based on a formula that the platform already knows well: turning a best-selling novel into a streaming success. In this case, it adapts the book of the same name by Marissa Stapley, published in 2021 and which went viral a few months later, when it was chosen as a recommendation for Reese Witherspoon’s reading club. From there, the book topped the sales charts for months. The plot, however, partially moves away from the original starting point. In the novel, Lucky Armstrong is a con artist who wins the lottery with a ticket purchased at random and cannot collect it without giving herself away. The series changes the mechanism: a million-dollar heist goes wrong, causes her husband to disappear and she finds herself pursued by both the FBI and a mafia boss. However, the result wants to preserve the spirit of the original character. Leading the cast, Anya Taylor-Joy returns to television for the first time since Netflix’s memorable ‘The Queen’s Gambit’. She’s joined by Annette Bening as her mother-in-law and crime boss, and the always-worthy Timothy Olyphant. The aforementioned Reese Witherspoon, after discovering the novel, continues to be linked to the story by producing it (this is not the first time she has done so, her hits were ‘Gone Girl’ and ‘Big Little Lies’), and TTaylor-Joy also serves as executive producer through her own company.Ladykiller. On this occasion, ‘Lucky’ seems to follow in the footsteps of ‘Presumed Innocent’, which was based on a best-seller by Scott Turow and also had a cast of bells headed by Jake Gyllenhaal. Here again we find great actors, a taste for intense thrillers (here seasoned with explosive action sequences) and a visual finish, as always in Apple TV+, which puts the platform several steps ahead of its competitors. Not much will be said about ‘Lucky’, but it will undoubtedly become one of the proposals to follow this summer.

My phone is almost five years old and the battery maintains its useful life at 85%. This is how I got it

by

My smartphone, a iPhone 13 Pro Maxis almost five years old and its battery retains 85% of its original capacity. It is not coincidence or good luck. It is the result of understanding what happens to a battery of lithium ions every time we charge it and consciously apply a handful of habits that slow down its degradation. Most users assume that a mobile phone’s battery is condemned to degrade without remedy in two or three years. And to a certain extent it is true: every lithium-ion battery loses capacity over time. But the speed at which it does so depends largely on how we treat hernot just its internal chemistry. In this context, we are interested in understanding two specific physical phenomena, voltage stress and thermal degradation, because they are the ones that wear out battery cells the most. And we also need to know the guidelines I have followed for almost five years to minimize them. They are not magic tricks. They are direct consequences of the electrochemistry that occurs inside the battery. What happens to a battery every time we charge it A lithium-ion battery works by moving ions between the cathode and anode through an electrolyte. When we charge the phone up to 100% we force the cathode to reach its maximum voltage potential. This high voltage state oxidizes the electrolyte in contact with the cathode and favors the dissolution of transition metals from its crystalline structure. This phenomenon is known as voltage stress, and it is cumulative: the longer the battery spends in that state of maximum voltage, the faster it degrades. An increase of 10 degrees Celsius doubles the speed of certain degradation reactions in the electrolyte A quick note before moving forward: that layer that forms on the cathode is called CEI (cathode solid electrolyte interface or cathode electrolyte interphase), and is the first cousin of the SEI (solid electrolyte interface or solid electrolyte interface) that grows on the graphite anode. At sustained high voltages, the IEC thickens uncontrollably, irreversibly consumes active lithium and reduces the usable capacity of the cell with each cycle. For this reason, it is worth using the 80% loading automation offered by both iOS and Android. In fact, I don’t charge my phone at 100% unless I know I’m going to need full battery life that day. Keeping the battery in an intermediate voltage range (between 20% and 80%) dramatically reduces the time the cells spend at the extremes of voltage where molecular wear is most aggressive. The second big enemy is heat, and this is where thermal degradation comes into play. Parasitic chemical reactions do not depend on voltage alone; They also accelerate with temperature, and do so in a non-linear manner. As a guideline, an increase of about 10 degrees Celsius can reach double the speed of certain degradation reactions in the electrolyte, a behavior consistent with the Arrhenius equation that governs the kinetics of any chemical reaction. This is why I avoid ultra-fast chargers in summer, especially if my phone is exposed to the sun or inside a thick case. Charging at 45, 65 or more watts generates considerable internal heat, and if that heat is not dissipated well (and in environments at 35 or 40 degrees Celsius it is not dissipated well), the cell temperature can approach 40-45 degrees Celsius, a range beyond which electrolyte degradation and cathode dissolution accelerate noticeably. I definitely prefer slower charges at 15 or 20 watts, even if they take longer: the battery appreciates it in the long run.

“Neither swimming nor walking, from the age of 50 it is absolutely necessary to do bodybuilding”

by

For decades, the medical and popular advice par excellence for people crossing the fifty-year-old barrier has been that they should walk every day, taking a walk or even sign up for swimming for being a really complete exercise. But we now know that they are completely insufficient if we want to achieve a good quality of life as the years continue to add up. The experts. The new tests that we have on the table make it clear that strength is essential, and the Spanish coach Álvaro Puche, a graduate in Physical Activity and Sports Sciences, point that “neither swim nor walk. From the age of 50 it is absolutely necessary to do bodybuilding.” A priori, this may sound radical to those who associate weights only with bodybuilding, but if we look at the current scientific evidence, Puche is not only right, but his warnings are fundamental for our longevity. The real enemy. The main argument for changing the pool for dumbbells has a clinical name, what is “sarcopenia“, which is nothing more than the loss of muscle mass with all the consequences that it has. Starting in our third decade of life, this process of muscle loss starts and steps on the accelerator once we cross 50 years of age. Walking or swimming at moderate intensity are excellent exercises for cardiovascular health, but they do not provide the stimulus necessary to stop muscle loss. Strength training, on the other hand, is the best clinically documented strategy for slowing and even reversing sarcopenia. And the sooner you start putting the brakes on, the better. The data. Science overwhelmingly supports the need to lift weight in adulthood, and we are not talking about isolated data, since a great meta-analysis showed that dedicating the minimum possible time to strength training reduces overall mortality by between 15% and 21%. Specifically, the risk of cardiovascular death drops by 19%. But you don’t have to live in the gym to do this, since science indicates that the benefit curve is “U” shaped. This means that the maximum benefit from exercise is achieved with just 60 minutes of strength exercise per week. Doing much more does not provide extra advantages, so the figure we have to achieve is not a great sacrifice nor a great expenditure of time. in women It is even more important if possible, since when menopause is reached, the loss of the ‘protective’ function of estrogen causes bone density to decrease, to the point that it can end up causing osteoporosis. This is why strength exercise becomes a great way to significantly increase bone density, especially with exercises focused on the hip. Lack of adhesion. Although in medical consultations it is increasingly common to ‘prescribe’ strength exercises, it is still a pending task for many. The problem may be the perception of older people, thinking that gyms or weight training are only for young people and that older people should only be left with the morning walk. A mistake that is blundering. On the other hand, there may be a lack of greater awareness on the part of health professionals when it comes to recommending this type of exercise, since clearly explaining the benefits of developing strength can be a good incentive for everyone to decide to start this exercise.
