I think that fast strides are the most powerful training stimulus for runners. For a glimpse at the physiology, I want to talk about my all-time favorite study. If we were playing FMK, I’d F this study, M this study, and K any study that is not this study....

Today was my hardest workout before the Javelina 100—an uphill treadmill supercompensation session accumulating 60 minutes of intervals at 10% grade, starting at threshold and ending harder. I think uphill treadmill threshold sessions can be magical for some athletes. Threshold work is classically defined as LT2 or easier, around what you could sustain for 1 hour. In practice, that feels relatively relaxed at first, and it only starts to get harder after you accumulate a substantial amount of volume. The rationale of threshold work is that it improves lactate shuttling, helping mitochondria be more efficient at processing and transporting lactate, preventing fatigue cascades even at harder efforts on other days (or at easier efforts in marathons or ultras). In other words, it’s primarily an aerobic stress. Faster is not better. The real-world obstacles with threshold work are twofold. First, for most of us, it’s pretty slow when done right, or way too hard when done wrong. A study on the training of elite athletes found that long intervals had the lowest correlation with long-term growth, and this conundrum is probably why—athletes do their long intervals too hard, breaking themselves down without the mechanical or aerobic stimulus to justify it. Second, outdoor threshold work can be an injury risk. If I tried this workout outdoors, it would wreck my calves and high hamstrings for days. The uphill treadmill can help athletes get around these hurdles. It’s slower by design, putting the emphasis squarely on the aerobic system. That helps athletes develop a much more precise understanding of threshold. But perhaps most significantly, the uphill treadmill reduces impact forces immensely. When I finish one of these—even a supercompensation session—I feel fine the next day, allowing me to absorb way more work (and more specific work to my goals). Particularly with age, I find that running training is about managing the efforts that are high impact to be limited and focused. While most of the uphill treadmill work I do is very controlled, it’s also ok to occasionally dig deeper. Today was about supercompensation. It’s not called The Pain Cave for nothing 🔥

Normalise RDL as a main movement. The Romanian Deadlift (RDL) or Heavy Barbell Hip Hinge is a powerhouse exercise that has gained a lot of popularity among strength and conditioning coaches, powerlifters, and bodybuilders alike. This movement is often called an “athlete maker" in my mind due to its ability to build strength, muscle mass, and athleticism in both men and women. One of the primary reasons why the RDL is so effective for athletes is because it is triphasic, for the uninitiated meaning it involves three distinct phases of muscle action: eccentric, isometric, and concentric. During the eccentric phase, the lifter is lowering the weight, which creates tension and stress on the muscles, leading to greater muscle damage and adaptation. The isometric phase occurs when the lifter pauses at the bottom of the lift, holding the weight in a static position, which increases the time under tension and helps to build strength and stability. Finally, during the concentric phase, the lifter raises the weight, activating the muscles in a way that promotes greater hypertrophy. Compared to a traditional deadlift off the floor, the RDL places a greater emphasis on the posterior chain, specifically the proximal hamstring, glutes, and erector spinae muscles. The lift also engages the distal hamstring muscles in a nearly fully extended position, promoting greater muscle activation and strengthening. The RDL is an excellent way to develop strength and hypertrophy in these muscle groups, leading to improved overall athletic performance, including greater power, speed, and explosiveness. Given the numerous benefits of the RDL, it should be a main movement in any training program that aims to improve strength, muscle mass, and overall athletic performance. Incorporating heavy barbell hip hinge movements, such as the RDL, into your training regimen can help to promote better posture, improved mobility, and greater overall strength and athleticism. So, whether you are a powerlifter, bodybuilder, or athlete, consider adding the RDL to your training program to take your strength and athleticism to the next level.

So, my opinion on what the Antarctic (Antarctica) Anomaly is that it's a type of frequency technology. It must be way more powerful than HAARP, as many have claimed it to be, because we would see these anomalies at other HAARP sites, and we don't, not like this. With that said, and I'm very much trying to avoid letting what I want it to be not play a part here, I think it is a technology that is being used either off the coast of Antarctica itself or Bouvet Island. A third possibility is an area just to the northwest of the island that looks odd. It's possible it is a sonar scan from a ship, but why in that remote location? It looks like an antenna set up or rows of something that is out of place. I also believe that the weather events and fires that have taken place in Africa could possibly have been because of this. Each time we saw the anomaly, it was followed by a destructive weather event in Africa. A weird connection to that is we have been told and warned of a very busy 2024 Atlantic hurricane season. This is in part because of the above-average Atlantic ocean temperatures, which is the fuel to Hurricanes. With all this info, it's possible to see how the Anomaly could be a frequency tech that can manipulate or create weather, And or WARM up the Ocean temps to purposely enhance the Hurricane season and Storm growth. Keep in mind that many of our hurricanes and many of the biggest hurricanes have come from the west coast of Africa and form over the Cape Verde islands before heading towards the Caribbean and the United States. This is all of course speculation, and I'm learning many new things every day, so this idea may morph over time as we learn more. In the end, it is very hard to ignore all these findings. #antarctica #anonaly #AntarcticaAnomaly #BouvetIsland

In a new study from MIT and the University of Queensland, 272 international experts were asked to judge the biggest risks from AI between now and 2030. They concluded that 18 of the 24 risks they looked at each carry at least a 1 in 10 chance of a catastrophic outcome, which they defined as something that kills more than a million people or wipes out more than 100 billion dollars. The risks they worried about most were not science fiction robots. They were AI being used to build weapons, launch large scale cyberattacks, and concentrate power and money in very few hands. None of this is a prediction that it will happen. It is a measure of how seriously the field's own experts take the danger. And the numbers are not small.

PHOTON COUNTING CT AND A NEW CONCEPT OF NORMAL CORONARY ARTERIES For more than 2 decades we have been performing Cardiac CT with constant improvements in all parameters (spatial, temporal and contrast resolution). The improvements were progressive in certain fields and steep in other (e.g.: the introduction of Dual Source CT that completely changed the range of temporal resolution achievable basically overnight and still is the most important source of flexibility in Cardiac CT scanning after almost 20 years). Spatial resolution instead was improved in a slow and progressive way until the test EID CT generations that achieved a spatial resolution of 250 microns. This allowed us to assess a coronary artery tree and define it as normal when no apprentice changes were visibile up to that value. But we know that the normal thickness of coronary artery walls is quite below that threshold. It is more in the range of 80-200 microns. Therefore, the very early changes in coronary artery wall thickness could not be picked up by EID CT technology. With the introduction of PCCT we can constantly achieve 100 microns spatial resolution which means that we work extol in range in which coronary artery disease starts. It also means that we don't see any thickening of the the coronary artery walls we have a much higher specificity and reliability. This concept is a transformative one because it allows us to shift earlier and earlier the beginning of atherosclerosis in our patients and think even more precisely in terms of cardiovascular prevention and monitoring. Movie: example of normal coronary artery tree with PCCT. A new era is coming into practice and it is the age of Photon Counting CT which pushes this boundaries further away. PCCT is a NEW Imaging Modality. PCCT is changing the game, the field, the language, the priorities and in the end it will change the entire infrastructure of diagnostic medicine. PS: note that PCCT images have to be reduced in resolution when uploaded in social media. #CardiacImaging #MedicalInnovation #StentAssessment #Radiology #PCCT #photoncounting #QuantumHD #CT #computedtomography #yesCCT #coronaryarterydisease #ischemia #naeotomalpha #Peak #Pro #Prime #speed #cardiac #highresolution #siemenshealthinners #CardiacCT #PhotonCountingCT #MedicalImaging #HeartHealth #CardiovascularInnovation #Radiology #AIInMedicine

🚨BREAKING: THE COUP IS OVER | WAGNER’S RETREATING This official statement from Prigozhin, the head of the Wagner group and the leader of this coup, says it all. I don't think anyone expected this: "They were going to dismantle PMC Wagner. We came out on 23 June to the March of Justice. In a day, we walked to nearly 200km away from Moscow. In this time, we did not spill a single drop of blood of our fighters. Now, the moment has come when blood may spill. That’s why, understanding the responsibility for spilling Russian blood on one of the sides, we are turning back our convoys and going back to field camps according to the plan." The President of Belarus, Lukashenko, has been in talks with Prigozhin all day and has taken credit for the peace agreement. Prigozhin accepted the terms of Lukashenko’s agreement and agreed to halt the movement of his forces and return back to his bases. The agreement also guarantees security for fighters of PMC Wagner. It seems that the attempted coup has come to an end, and Prigozhin, along with his men, will return to their bases. Reports of Wagner forces not only leaving Moscow Oblas, but also leaving Rostov. Russian media reports that criminal cases have already been dropped from Yevgeny Prigozhin and that Prigozhin and his forces will receive FULL IMMUNITY Restrictions on the movement of vehicles have been lifted from the Voronezh region which saw clashes earlier during the coup. MY THOUGHTS: - I did not expect this would end peacefully with a deal as it seemed both sides seemed at the point of no return - I have no idea how Prigozhin and Putin can both operate in Russia with what just transpired, and I also have no idea what will happen with the war in Ukraine but I wouldn’t be surprised if we see a space deal reached. - Today was another example of citizen journalism replacing mainstream media with UNBIASED and UNCENSORED live breaking news. - I am fried, been awake for more than 30 hours, initially doing a space with former Pakistani Prime Minister Imran Khan before shifting to the Coup space which is at 21 hours and counting. Time for me to finally sleep!

Today, at Redeemer’s University Redeemer's University, Ede, Osun State, I was glad to commission the new Institute of Genomics and Global Health, marking a significant evolution from ACEGID’s @acegid status as a center of excellence. This moment is not only a proud achievement for all those involved, but it also stands as a powerful symbol of what African scientific leadership can achieve on the global stage. Under the visionary leadership of Prof Christian Happi Christian T. Happi, the team at ACEGID has made extraordinary strides in genomic research, particularly in addressing some of the most pressing infectious disease challenges of our time. The inauguration of the Institute reminds us that the work being done by the ACEGID team is a global public good, benefiting not only Nigeria and Africa but also contributing to global health security. The partnerships fostered between institutions and scientists from the Global North and South are a testament to our shared commitment to protecting and advancing human health. This collaboration has demonstrated what is possible when we work together to confront challenges that affect us all. Under the visionary leadership of President Bola Ahmed Tinubu, Bola Ahmed Tinubu health security remains a central pillar of our broader strategy to transform Nigeria’s health system, unlock the value chain, and improve population health outcomes. This is why supporting cutting-edge scientific research, like the work at this Institute, is essential. We need to create a health system environment with strong public health capabilities to withstand the potential and evolving threats posed by infectious diseases and the ongoing impacts of climate change. The pace at which new health threats are emerging is accelerating, and with it, the need for robust scientific responses. The innovations in genomics we are witnessing at ACEGID provide a glimmer of hope, offering us the tools we need to be better prepared for what may come. The Federal Government of Nigeria Government of Nigeria is fully committed to supporting these efforts, knowing that science must lead the way in securing a healthier future for all.

Madain Saleh, also known as Al-Hijr, is a pre-Islamic archaeological site located in the northwest of Saudi Arabia. It is one of the most important archaeological sites in the Middle East and was designated as a UNESCO World Heritage site in 2008. Madain Saleh is a place of great historical and cultural significance, and it is a must-visit destination for anyone interested in the history and culture of the Arabian Peninsula. Madain Saleh was the second city of the Nabataean kingdom, which was established in 2nd Century BC. The Nabataeans were an Arab tribe who were known for their expertise in carving tombs and buildings out of rock. They were also skilled in agriculture, trade, and commerce. The Nabataean kingdom was centered in Petra, which is located in modern-day Jordan. Madain Saleh served as a strategic outpost for Nabataeans, and it was an important stop on the trade routes that connected the Arabian Peninsula with the Mediterranean world. Archaeological site of Madain Saleh covers an area of 13 square kilometers. It is located in a remote desert region, and it is surrounded by rocky mountains and valleys. The site contains around 130 tombs, which were carved out of the sandstone cliffs. The tombs are adorned with intricate carvings and inscriptions, which provide insights into the culture and religion of the Nabataeans. The most famous tomb at Madain Saleh is the Qasr Al-Farid, which means "the lonely castle." This tomb is located on a hilltop and is surrounded by a large courtyard. It is the largest tomb at the site, and it is considered to be one of the finest examples of Nabataean architecture. The tomb was never completed, and it is believed that it was abandoned after the death of the Nabataean king who commissioned it. Another important tomb at Madain Saleh is the Tomb of Lihyan son of Kuza. This tomb is located in the southern part of the site and is carved into a rock cliff. It features a large entrance hall, a central chamber, and a series of smaller rooms. The tomb is decorated with intricate carvings and inscriptions, which provide insights into the religious beliefs of Nabataeans. Madain Saleh is not just a site of tombs; it also contains a number of other important structures. These include the Al-Khuraymat and Al-Sabika temples, which were used for religious ceremonies and rituals. The site also contains a number of houses, wells, and cisterns, which provide insights into the daily lives of the Nabataeans. Madain Saleh was abandoned in the 3rd Century AD, after decline of the Nabataean kingdom. The site was rediscovered in the 19th Century by the Swiss traveler Johann Ludwig Burckhardt. Since then, it has been studied by archaeologists from all over the world. The site is now managed by the Saudi Commission for Tourism and National Heritage, which has carried out extensive restoration and preservation work. Madain Saleh is not just a site of historical and cultural significance; it is also a place of great natural beauty. The site is surrounded by rugged mountains and valleys, and it is home to a diverse range of flora and fauna. Visitors to the site can enjoy hiking and camping, as well as exploring the ancient ruins. Madain Saleh is a site of great historical and cultural significance, and it is a must-visit destination for anyone interested in the history and culture of the Arabian Peninsula. Ancient ruins at Madain Saleh provide a glimpse into the engineering and architectural skills of the Nabataeans, as well as their religious beliefs and cultural practices. However, as the site becomes an increasingly popular tourist destination, there are concerns about its preservation and the impact of tourism on the local environment. It is important that the Saudi government and local communities work together to ensure that the site is protected and that tourism is managed in a sustainable way. 🎥© Paris Verra #archaeohistories

The site is surrounded by rugged mountains and valleys, and it is home to a diverse range of flora and fauna. Visitors to the site can enjoy hiking and camping, as well as exploring the ancient ruins. Madain Saleh is a site of great historical and cultural significance, and it is a must-visit destination for anyone interested in the history and culture of the Arabian Peninsula. Ancient ruins at Madain Saleh provide a glimpse into the engineering and architectural skills of the Nabataeans, as well as their religious beliefs and cultural practices. However, as the site becomes an increasingly popular tourist destination, there are concerns about its preservation and the impact of tourism on the local environment. It is important that the Saudi government and local communities work together to ensure that the site is protected and that tourism is managed in a sustainable way. 🎥© Paris Verra #archaeohistories

Brainrotting teens watching short form memes so much to the point that parts of the fragments of other memes become even more short form and get colluded in other memes to the point that it really doesnt make sense. However. Brain loves pattern recognition of these patterns and nonsensical randomly shown fragments of memes, because it is not long form reward, nor short form reward — but instantaneous; it is the only form of pleasure it can feel So brain tries to look for these patterns unconsciously, it sees patterns and similar resemblance in random things and adds a symbolical emotional labeling of truth to it. So everything becomes a piece of information and data. It gets stored in their subconscious brain and fires up everytime there is a resemblance. Extremely dangerous if weaponised but no one sees the patterns yet. However because of these pattern behaviours teens are split into two categories, the brainrots which God knows how it will end with them — consumers and slaves that later on might have no free will and be driven by pure chemical instinct. And those who see for truth in patterns. The latter is able to overcome modern day censoring and freedom of speech mechanisms, and possibly overcome the evil trying to control the world with pure silliness and having fun. (67 is part of a random pattern that someone said during a match score, and it became viral, nothing more but a collective participation to which youth finds identity by being and acting in it; “performing”) Its beauty lies not in the act but in those individuals that look beyond the chemical instincts of the lower mind. Example of the video below. It shows many fragmental elements of history, symbolism, that is collaged into art. Which by being seen individually or collectively it shows the expression on how man uses its own soul for these kind of co-creations he choses to participate in creation. Symbolism that can leave a person ask for its meaning and search for it, only by questioning himself not by a direct answer (short or long form). Of course which extreme beauty there is also extreme ugliness which are out there which I wont show here Lets see how it really turns out to be honest, West has no protection toward the subjective, the feminine, the subconscious. To which the inner sins of man try to exploit.

OK, I have a definitive word on the CJ Abrams play from today's Pittsburgh Pirates at Washington Nationals game after talking with Elias Sports Bureau on this. This play will stay as a sacrifice fly. The originial ruling of NOT a sacrifice fly was for the exact same reason that I thought, which is that the infielder is not running into the outfield, which is year's past would have been correct As it was explained to me, in past years, an infielder had to be running almost in a straight line towards the outfield wall to be considered "running in the outfield". Here, since he is running, and he ends up further away from home (157 feet) than when he started (145 feet), this is going to count as a sacrifice fly. That definition is changing, in part from this play to help bring greater consistency, and to take some of the guesswork out of it (the argument that he is running into the outfield as opposed to more parallel). Now, folks all the time ask "why doesn't MLB publish the OS Manual" and I always say because it is a living document that can have the wording change, and the wording for this play will be modified to something like "more towards the outfield wall than towards home plate" to eliminate any confusion. The big key to this play is that he was running on a full sprint. Also, and this is helpful for me, but for all fly ball outs that score a run, Elias Saba reviews to ensure consistency. So, yes, it's a sacrifice fly, and now that I have that info from Elias themselves, that sort of settles this one. Sounds like the guidelines for this definition will be changing, either this season, or certainly for next season.

I’m excited to announce my new role as Growth Lead at Plume! 🐦‍🔥 6 months ago, I had my first call with Chris Yin and surprisingly, he changed my mind. I was skeptical of a web3-native project trying to bridge the traditional world into ours. His thesis of a permissionless blockchain environment was antithesis to what I believed in at the time. After about 45 minutes of deep discussion, I could finally see it. I dropped all of my other RWA investment prospects and pointed myself towards Plume. From there, things got quiet for a while. Myself and the 280 partners debated the RWA sector as a whole and quietly observed Plume’s progress on the sidelines. Fast forward a few months and I had finally realized a thesis of my own; In crypto, you’ll generally find two key types of participants: speculators and yield chasers. Speculators lower their risk threshold in search of the next 100x, closely following trends and trying to capture opportunities early. It is a game that requires forward-thinking, intuition, and a lot of luck. These people range in financial status, with some looking to make their first bucket of gold, with the others trying to hit another big win and buy their second lambo. Yield chasers are a different breed of folks. They may not want to ape their entire portfolio into memes, rather they enjoy the attractive returns that DeFi offers that they generally wouldn’t be able to find in the traditional world. These folks generally aren’t looking for lambo, but believe that they will still be living well without the stress of going to zero. But as we see every cycle, Bitcoin crashes, DeFi collapses, and another round of fuzzy-haired fellas find their way over to the Metropolitan Detention Centre. Crypto dies, retail gets burned, the regulators swoop in and start raising hell, and the cycle repeats. Why does it have to be this way? Of course market cycles are natural and perhaps healthy, but why the catastrophe at the end each time? There must be a better way. And then it hit me. RWAfi is and always was the answer. The road at the end of all roads. It’s a nice road, paved with the blood, sweat, and tears of those truly trying to connect the entire world to our industry. Whether you made a major bag and want to move into wealth preservation or lost it all and no longer want to live the life of a degenerate gambler and are comfortable with a more stable approach to wealth building, eventually, everyone ends up chasing juicy yields. And we all know that there is only one sector of our industry that can consistently deliver attractive yields through bull and bear. There is only one sector that can support all the TVL that is currently sitting in vaults that are unable to sustain the yields they promised. The nature of the vertical makes it constantly aware of regulatory considerations. RWAfi is a sleeping giant, and not only will it unlock a $400T market, it will also catalyze an incredible amount of growth resembling tens of trillion in newly created value and opportunity. We are so early. That, paired with the incredible team Teddy @shukyeerwa Ivy Kang and the other 40 cracked believers that are pushing beyond their limits is the reason I bet on Plume. We have everything it takes to make it 🤝 I have to give a special shout out to J for how supportive he has been with this move. 280 Capital is married to Plume now and I’m sure we will be collaborating on a lot moving forward. Another shoutout to one of the great minds of this industry JacobK whose conviction in Plume really pushed me to purse this role🙏🏾 Vibes are all-time high with this team, and bring a fresh combination of competence, experience, and true belief in the platform that we are building. Mark my words, Plume will unify the RWAfi sector and pave the way as one of the giants of this industry. Let’s fucking do this. 🐦‍🔥 Goons in complete control.

Contact in the desert was the biggest ever this year and so was the sky watch. We witnessed dozens of orbs. With 5 minutes left before the hotel turned the lights on, I told more than a 1000k people present why pointing my laser in a certain direction that the phenomenon may give us a grand Finale and it may be an orb with wings. Within seconds a glowing orb with wings appeared and flew past the crowd. No it’s not a bird if you If you want to learn something about the phenomenon and 20 years of research with scientists and not speculation , join us on one of our adventures you will never be the same. We have this on several cameras from full spectrum to cell phones to Two types of night vision. Also scientists from NASA and Lockheed the NSA and The CIA were standing next to me during the filming of this orb and has witnessed this many times.

Slow Progress is the New Reality of Modern Wars There are many people commenting on Russian difficulties and coming up with numerous reasons for their alleged collapse. I absolutely do not see any collapse; on the contrary, Russia has already normalized a state of war in Ukraine, which boosts its economic and industrial growth. The difficulties faced by Russia today are the same as at the beginning of the war, with soldiers having to spend up to half of their initial salaries on their own equipment, delays in pensions, and a series of other problems that are mirrored on the Ukrainian side, even with all the support from allies. The war today is much less lethal than it was months ago, and both Russian and Ukrainian losses have significantly decreased during this phase. Lethality has fallen, but Russian advances persist. And why are they slow? Is it a Ukrainian tactic? No. They are slow because they are accompanied by the deployment of communication infrastructure like signal repeaters for drones, the advancement of artillery guided by drones, maneuvers using FAB and more recently ODAB bombs against Ukrainian drone operators' facilities, infiltration by reconnaissance teams, saboteurs, and a series of protocols they have developed. That conventional war with rapid advances no longer exists, and in the context of a battlefield dominated by drones, it is unlikely to return. Modern wars will have slow progress, as seen in the attacks and counter-attacks of the Russians and Ukrainians in this war. Contemporary military forces are still unable to see this new reality of war. When analyzing the Russian advance, it's important to consider that all these maneuvers take days to unfold, but the point is that the Russians have already adapted to this pace, not bothered whether a particular advance will take 3 weeks or 3 months. They advance continuously following tactical protocols with little threat from Ukrainian forces, which, without new equipment, have had their defensive tactics remain almost unchanged over the past two years, relying mainly on drones and making it easier for Russian studies of countermeasures. And what can Ukraine do in this situation? I see few options, but one would be to delay the Russian advance with a good number of missiles, though personally, I find it unlikely that they will reach Ukrainian hands. It wouldn't have the power to change the balance of the war, but it would guarantee more time, which is important because the battlefield is dynamic, and the implementation of new tactics based on innovative weapons can change everything overnight. A war that seems almost lost today could take a different turn in weeks. Time is crucial for Ukraine, which has fronts only about 130 km from cities like Zaporizhia and Dnipro.

The fascinating concept of Non-Newtonian fluids, which transition from a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.

People say running is bad and that it makes you look old and wastes away your muscle People are dumb That only happens if you run for to long at to high of a heart rate If you run at 130-140 beats per minute with a smile on your face it’s actually some of the best therapy there is If you are running and you can’t smile and it looks like you are in agony and can’t hold a pleasant conversation you are doing it wrong and that’s what will cause you to look old and frail This is called “the sweet spot” folks and it can be used for way more than just running
