Ratan Tata Death: Common Age-Related Health Issues And How To Address Them

Ratan Tata

Industrialist, philanthropist and national icon <span>Ratan Tata</span> passed away late on Wednesday at Mumbai's Breach Candy Hospital. He was 86 years old and struggling with several age-related health issues including low blood pressure. While the Chairman Emeritus of Tata Group, just two days ago, issued a statement saying that he was in "good spirit," he was hospitalized for a condition called orthostatic hypotension (OH) wherein blood pressure suddenly drops. He was also suffering from other old-age health complications. 

<h2>How Common Is Sudden Drop In Blood Pressure? </h2>

A sudden drop in blood pressure—known as orthostatic hypotension (OH) or postural hypotension—is common condition in elderly people. A person suffering from this sees a sudden drop in their blood pressure when sitting and standing or lying down. As a result, they feel dizzy or even faint. A study published in the <em>Journal of Family Medicine and Primary Care</em> found that more than 10 per cent of the elderly population aged 65 and older suffer from this condition.

<strong>What are the symptoms of OH? </strong>

Most common symptoms of orthostatic hypotension are dizziness or lightheadedness. However, a person could also experience the following: 

<ul><li>Nausea</li><li>Headache</li><li>Weakness</li><li>Blurred vision</li><li>Confusion</li></ul><h2>What Are Other Age-Related Health Issues? </h2>According to the World Health Organization (WHO), common conditions faced by older people include hearing loss, cataracts and refractive errors, back and neck pain and osteoarthritis, chronic obstructive pulmonary disease, diabetes, depression and dementia. 

<strong>Hearing loss</strong> can manifest through symptoms such as difficulty understanding speech, especially in noisy environments, frequent requests for repetition, and a general muffling of sounds. Individuals may also withdraw from conversations. Preventive measures include protecting the ears from loud noises with earplugs or earmuffs, avoiding prolonged exposure to loud environments, and getting regular hearing check-ups, particularly as one ages. Cataracts typically present with blurry or cloudy vision, increased difficulty seeing at night, sensitivity to light, and faded colors. To prevent cataracts, it is advisable to wear sunglasses that block UV rays, maintain a diet rich in antioxidants, avoid smoking and excessive alcohol, and manage chronic conditions like diabetes.

<strong>Refractive errors</strong>, which cause blurred vision at various distances, eye strain, and headaches, can often be managed with regular eye exams to ensure updated prescriptions. Practicing the 20-20-20 rule—looking at something 20 feet away for 20 seconds every 20 minutes—can help reduce eye strain, as can wearing protective eyewear when necessary. Back and neck pain can manifest as a dull ache, sharp pain radiating to the limbs, stiffness, or muscle spasms. To prevent these issues, maintaining good posture, engaging in physical activity, using ergonomic furniture, and practicing stress-reduction techniques like yoga can be beneficial.

<strong>Osteoarthritis</strong> symptoms include joint pain and stiffness, especially after activity or periods of rest, swelling around joints, and decreased flexibility. Preventive measures involve maintaining a healthy weight to lessen joint stress, participating in low-impact exercises, incorporating strength training, and using proper lifting techniques. Chronic obstructive pulmonary disease (COPD) presents with shortness of breath, a chronic cough with mucus, wheezing, and fatigue. Preventive actions include avoiding smoking, staying active, getting vaccinated against respiratory infections, and effectively managing chronic conditions.

<strong>Diabetes </strong>symptoms often include increased thirst, frequent urination, extreme fatigue, blurred vision, and slow-healing sores. Prevention focuses on maintaining a healthy diet low in refined sugars and high in fiber, engaging in regular physical activity, and monitoring blood sugar levels. Depression can manifest as persistent sadness, loss of interest in once-enjoyed activities, changes in appetite or sleep, and difficulty concentrating. Preventive strategies involve fostering strong social connections, engaging in physical activity, practising mindfulness, and seeking professional help when needed.

<strong>Dementia</strong> symptoms can include memory loss, confusion with time or place, and changes in mood or personality. To help prevent dementia, staying mentally and socially active, maintaining a healthy diet—especially the Mediterranean diet—managing cardiovascular health, and avoiding smoking and excessive alcohol consumption are recommended.

A fading sense of smell may do more than hint at aging—it could be one of the earliest warning signs of Alzheimer’s disease. New research from DZNE and Ludwig-Maximilians-Universität München reveals that immune cells in the brain mistakenly target and destroy nerve fibers critical for odor perception, offering fresh clues into how the disease begins and how it might be diagnosed sooner.

Patients and families may notice that scents seem muted or distorted, sometimes years before other symptoms. Until now, the exact cause behind this early warning sign remained elusive.

A new study led by researchers at the German Center for Neurodegenerative Diseases (DZNE) and Ludwig-Maximilians-Universität München (LMU) sheds fresh light on the mystery. The findings, published in Nature Communications, suggest that the brain’s own immune system mistakenly destroys nerve fibers vital for processing odors. This breakthrough could open the door to earlier diagnosis—and possibly earlier treatment—of Alzheimer’s.

Smell perception begins in the olfactory bulb, a small but complex structure in the forebrain that receives input from sensory receptors in the nose. But the olfactory bulb doesn’t work alone. It relies on nerve fibers extending from the locus coeruleus, a brainstem region that helps regulate attention, blood flow, and sensory processing.

The new study shows that in early Alzheimer’s disease, this communication line is disrupted. Microglia—immune cells that normally act as the brain’s cleanup crew—start dismantling the nerve fibers linking the locus coeruleus and olfactory bulb. This immune-driven attack deprives the brain of crucial odor-processing pathways, leading to smell loss.

“Our study suggests that in early Alzheimer’s disease, changes occur in the nerve fibers linking the locus coeruleus to the olfactory bulb. These alterations signal to the microglia that affected fibers are defective or superfluous. Consequently, the microglia break them down,” explained Dr. Lars Paeger of DZNE and LMU.

<h2>What Is The “Eat-Me” Signal That Triggers Alzheimer’s?</h2>

At the heart of this immune misfire lies an unusual molecular change. Researchers observed that phosphatidylserine, a fatty acid normally tucked inside the protective membrane of neurons, shifts to the cell’s outer surface in affected nerve fibers.

When this happens, microglia interpret it as an “eat-me” signal. Under normal conditions, this signal supports a healthy process called synaptic pruning, where unnecessary or damaged connections are cleared away. But in Alzheimer’s, this mechanism seems to go awry.

Paeger explained that hyperactive neurons—cells firing abnormally due to early disease changes—appear to trigger this membrane shift. Once flagged as dysfunctional, these otherwise critical smell-related fibers are targeted and destroyed.

PET imaging scans in living patients, which confirmed damage to smell-related nerve circuits in people with Alzheimer’s or mild cognitive impairment.

“Smell issues in Alzheimer’s disease and damage to the associated nerves have been discussed for some time. However, the causes were unclear until now. Our findings point to an immunological mechanism as cause for such dysfunctions – and, in particular, that such events already arise in the early stages of Alzheimer’s disease,” said Prof. Joachim Herms, senior researcher on the study.

<h2>Why Smell Loss Is Important in Diagnosis of Alzheimer’s?</h2>

More than 6 million Americans currently live with Alzheimer’s disease, a number projected to rise sharply as populations age. Yet diagnosis often comes late, when memory loss and cognitive decline are already advanced.

Smell loss offers an earlier red flag. If the biological mechanisms behind it can be mapped and measured, doctors could potentially screen for Alzheimer’s years before symptoms interfere with daily life. This could be especially critical as new treatments, such as amyloid-beta antibodies, are designed to work best in the earliest phases of disease progression.

“Our findings could pave the way for the early identification of patients at risk of developing Alzheimer’s, enabling them to undergo comprehensive testing to confirm the diagnosis before cognitive problems arise,” Herms noted. “This would allow earlier intervention with amyloid-beta antibodies, increasing the probability of a positive response.”

The study also highlights the often-overlooked locus coeruleus, a small cluster of neurons deep in the brainstem. Beyond smell, this structure regulates blood flow, sleep-wake cycles, and stress responses through widespread connections.

Damage to the locus coeruleus is one of the earliest detectable signs of Alzheimer’s, even before amyloid plaques and tau tangles spread widely. The new findings underscore that its breakdown may not only affect memory and attention but also disrupt sensory pathways, making smell loss one of the first noticeable symptoms.

<h2>Can Sense of Smell Be Preserved?</h2>

While the research answers critical questions, it also raises new ones. If immune cells misidentify smell-related fibers as expendable, can this process be slowed or stopped? Could therapies aimed at stabilizing neuron membranes prevent the fatal “eat-me” signal from being displayed in the first place?

Future studies will likely explore whether drugs that regulate microglial activity—or protect the integrity of phosphatidylserine positioning—could preserve nerve connections in early Alzheimer’s.

Meanwhile, incorporating smell testing into routine checkups for older adults may become a more practical step. Inexpensive scratch-and-sniff exams already exist and could serve as a noninvasive screening tool to identify people who may need further evaluation.

For families watching loved ones struggle with subtle changes—whether misplaced keys, unusual forgetfulness, or an inability to smell morning coffee—the findings offer clarity. Smell loss is not just an odd, isolated symptom but a biological signal that Alzheimer’s is affecting the brain long before dementia sets in.

Recognizing this signal early could give patients and clinicians a window of opportunity: time to prepare, time to plan, and perhaps in the future, time to intervene with treatments that slow or alter the course of disease.

Alzheimer’s remains one of the greatest public health challenges of our time. While there is still no cure, understanding its earliest signals brings us closer to meaningful change. By uncovering how immune cells mistakenly dismantle smell pathways, this study not only solves a long-standing puzzle but also lays the foundation for earlier, more effective care strategies.

The sense of smell may be more than just a window to the world—it may be a window into the earliest changes of Alzheimer’s disease.

Spinal cord injuries have long posed one of the most stubborn challenges in medicine. Affecting more than 300,000 people in the United States alone, these injuries often lead to permanent <span>paralysis</span> because damaged nerve fibers fail to regenerate across the site of trauma. Traditional therapies focus largely on rehabilitation and symptom management rather than reversing the underlying injury. Now, a groundbreaking study from the University of Minnesota Twin Cities suggests that a combination of 3D printing, stem cells, and lab-grown tissues could change that narrative. Researchers have engineered tiny scaffolds that guide stem cells to form nerve fibers capable of bridging severed spinal cords. In rat models, this approach restored nerve connections and movement—offering a tantalizing glimpse into the future of <span>paralysis treatment</span>.

At the heart of this innovation are organoid scaffolds—microscopic 3D-printed structures designed to direct stem cell growth. These scaffolds contain a network of tiny channels that can be seeded with spinal neural progenitor cells (sNPCs). Originating from human adult stem cells, sNPCs have the potential to differentiate into the various types of neurons needed for spinal cord repair. The scaffold essentially provides a framework for these cells, ensuring they grow along the correct pathways to reconnect disrupted nerve circuits.

Guebum Han, a former postdoctoral researcher in mechanical engineering at the University of Minnesota and the study’s first author, explains, “We use the 3D printed channels of the scaffold to direct the growth of the stem cells, which ensures the new nerve fibers grow in the desired way. This method creates a relay system that, when placed in the spinal cord, bypasses the damaged area.”

To test their approach, the researchers transplanted the scaffolds into rats with completely severed spinal cords. Over time, the stem cells differentiated into mature neurons and extended their nerve fibers in both directions—toward the head (rostral) and toward the tail (caudal)—forming new connections with the host’s existing spinal circuitry.

The results were remarkable. Rats that received the organoid scaffolds showed significant functional recovery compared to controls, regaining movements that were previously impossible. The new neurons integrated seamlessly into the host tissue, demonstrating that lab-grown spinal tissue could not only survive transplantation but also restore communication across previously severed areas.

<h2>Can Lab-Grown Organs Help Patients?</h2>

While the research is still in its early stages, the potential implications for human medicine are profound. Spinal cord injuries have been notoriously resistant to treatment because adult nerve cells rarely regrow once damaged. This study provides proof-of-concept that targeted, scaffold-guided stem cell growth can rebuild the neural network necessary for motor function.

Ann Parr, professor of neurosurgery at the University of Minnesota, emphasizes the significance: “Regenerative medicine has brought about a new era in <span>spinal cord injury</span> research. Our laboratory is excited to explore the future potential of our ‘mini spinal cords’ for clinical translation.” The team hopes to refine the technique, scale up scaffold production, and move toward clinical trials that could one day benefit people living with paralysis.

Despite the promising results, several hurdles remain before this technology can be applied to humans. Scaling the tiny lab-grown spinal cords to the size necessary for human injuries will require sophisticated bioengineering solutions. Immune rejection and integration into a complex, pre-existing nervous system present additional challenges. Moreover, safety and efficacy will need to be rigorously tested in larger animal models before human trials can proceed.

The ethical considerations of stem cell use and genetic manipulation also require careful navigation. While adult stem cells used in this study bypass some of the ethical debates associated with embryonic stem cells, clinical applications must still adhere to stringent regulatory standards.

The merging of 3D printing, stem cell science, and lab-grown tissue engineering represents a paradigm shift in <span>regenerative medicine</span>. The concept of “mini spinal cords” could open the door to therapies not only for spinal cord injuries but potentially for other neurodegenerative diseases that involve nerve degeneration, such as amyotrophic lateral sclerosis (ALS) or multiple sclerosis.

Moreover, these technologies exemplify the broader trend of personalized medicine. By tailoring organoid scaffolds to individual patients, it may become possible to repair nervous system injuries with unprecedented precision. This could drastically improve outcomes, reduce rehabilitation times, and enhance quality of life for patients who currently have few options.

The University of Minnesota study is an early but significant step toward reversing paralysis. By combining 3D-printed scaffolds, stem cell biology, and lab-grown spinal tissue, researchers have demonstrated that damaged neural pathways can be rebuilt and functional recovery is achievable—at least in animal models.

While human applications are still a way off, the research provides a blueprint for the future of spinal cord repair and regenerative neuroscience. For the millions affected by spinal cord injuries, these tiny lab-grown spinal cords could one day offer more than hope—they could offer a pathway to regained movement and independence.

Psychologist Says You Don't Need To Talk About Your Feeling In Conflicts: Here's What Emotionally Intelligent People Do

psychologist says you don't need to talk about your feeling in conflicts: here's what emotionally intelligent people do

what is the difference between life expectancy and healthy life expectancy?

At a military parade in Beijing, an open-mic moment between Chinese President Xi Jinping and Russian President Vladimir Putin revealed an unusual exchange. The leaders were overheard discussing organ transplants and the possibility of dramatically extending human life. Putin even raised the prospect of “eternal life” through biotechnology, according to translated remarks aired on Chinese state TV. The conversation, captured as Xi, Putin, and North Korean leader Kim Jong Un walked through Tiananmen Square, has fueled fresh debate on the limits of science and longevity. Both Xi and Putin, in power for 13 and 25 years respectively, have shown no signs of stepping down.

The pageantry was meant to project strength, but a stray hot mic gave the world something unexpected: an intimate glimpse into how two of the most powerful men on Earth think about the human lifespan.

Putin’s interpreter was caught saying, “Biotechnology is continuously developing. Human organs can be continuously transplanted. The longer you live, the younger you become, and even achieve immortality.” Xi responded, almost casually: “Some predict that in this century humans may live to 150 years old.”

The microphones were quickly faded out, and the livestream camera cut away. But the brief exchange rippled far beyond the parade. Could 150 really be the ceiling for human life—or even a realistic milestone?

Both Xi and Putin later confirmed the conversation, with Putin remarking to Russian media that new medical advances, including organ replacement, could extend “active life” significantly. For leaders who have each been in power for more than a decade—and show no signs of stepping aside—the notion of extending life carries not just personal but political undertones.

This wasn’t idle speculation in a vacuum. Russia, China, and the United States are all investing heavily in biotechnology, regenerative medicine, and artificial intelligence as tools not only of economic growth but also of national prestige. Against that backdrop, Xi’s mention of 150 years sounded less like science fiction and more like a pointed acknowledgment of what researchers are seriously debating.

At present, global life expectancy hovers around 73 years, with wealthier countries averaging in the low 80s. The record for the oldest documented human belongs to Jeanne Calment, a Frenchwoman who lived to 122 before passing in 1997.

But it’s important to separate two concepts: average life expectancy (how long most people live, heavily influenced by disease, healthcare access, and environment) and maximum lifespan (the theoretical upper limit of human survival under ideal conditions). Average life expectancy has steadily climbed over the past century thanks to vaccines, antibiotics, improved sanitation, and better maternal care. Maximum lifespan, by contrast, has barely budged.

That’s why Xi’s remark matters. He wasn’t talking about incremental gains—he was floating the possibility of breaking through a biological barrier.

<h2>Can Humans Live As Long As 150 Years?</h2>

A team of scientists from Singapore, Russia, and the United States recently modeled human resilience using blood samples from more than 70,000 people aged up to 85. They tracked fluctuations in white and red blood cells to create a measure called the Dynamic Organism State Indicator (Dosi), which captures the body’s ability to recover from stress and illness.

Their conclusion was striking: resilience collapses completely around age 150, setting an upper bound for human lifespan. This wasn’t a forecast of what people will achieve anytime soon—it was a theoretical ceiling based on current biology.

Put simply, the study suggests that even if you dodge heart disease, cancer, infections, and accidents, your body will eventually lose its ability to recover. That’s the point at which life becomes unsustainable.

<h2>Is Living Till 150 Years Plausible Or Out of Reach?</h2>

From a biological standpoint, the 150-year limit makes sense. Organs age, stem cells lose regenerative capacity, and the body accumulates damage at the cellular level. At present, most human organs seem capable of functioning for 110 to 120 years under ideal conditions. Beyond that, decline accelerates.

Yet science is moving fast. Regenerative medicine, organ transplantation, and lab-grown tissues could shift the baseline. Already, researchers have extended the lives of worms tenfold and mice by 30–40%. Humans, with more complex biology, are harder to push, but the trajectory suggests improvement is possible.

Still, adding 25–30 years of healthy life is far more realistic in the near future than reaching 150. As one researcher quipped, “We might not see immortality, but 110 could become the new 90.”

Evidence from real-world populations supports the idea that genetics and lifestyle can push lifespans well beyond the norm. The “Blue Zones”—regions like Okinawa in Japan and Sardinia in Italy—produce unusually high numbers of centenarians. Their secrets aren’t futuristic: plant-heavy diets, daily movement, strong community ties, and low chronic stress.

Even so, these populations rarely see people surpassing 110. Jeanne Calment remains an outlier, not a model. Which raises the question: are biology and environment already giving us the maximum return, or is medicine the only path to break through?

<h2>What Role Does Biotechnology Play?</h2>

This is where Putin’s remark about organ transplants comes in. Medicine has already normalized replacing failing hearts, kidneys, and joints. Stem cell therapies are being tested to repair damaged tissues. Artificial intelligence is accelerating drug discovery. CRISPR and gene editing open the possibility of correcting mutations that drive aging and disease.

Theoretically, if each organ could be replaced or rejuvenated before it fails, the body could remain younger for longer. The challenge is that aging is systemic. Replacing a heart doesn’t stop immune decline, nor does repairing a kidney fix memory loss. The body doesn’t age in silos; it ages all at once.

<h2>How Can Political Leaders Shape The Theory of Longevity?</h2>

It’s no accident that authoritarian leaders are voicing interest in radical life extension. Both Xi and Putin oversee nations that pour resources into biotechnologies, often with fewer ethical guardrails than in the West. Extending human lifespan is not just a health goal—it’s a geopolitical lever, a way to showcase scientific dominance.

At the same time, public health experts caution against letting these conversations distract from pressing needs. In countries where average life expectancy still lags below 70, access to vaccines, clean water, and chronic disease care would do far more for human survival than speculative anti-aging research.

For now, the 150-year limit is a provocative talking point, not a practical horizon. But Xi and Putin’s hot mic exchange underscores something deeper: longevity science has moved from the fringes to the geopolitical stage.

If history is any guide, the biggest gains won’t come from science fiction-style immortality but from steady, incremental progress—cutting smoking rates, controlling hypertension, managing diabetes, and ensuring equitable access to healthcare. These measures, not transplants or futuristic drugs, are what extend average life expectancy year after year.

The mic may have been unguarded, but the conversation it captured was anything but trivial. Leaders of two nuclear powers spoke openly about the possibility of living indefinitely. While the science points to 150 years as a theoretical ceiling, the more pressing challenge for humanity is not how long we can live, but how well.

As researchers continue probing the biology of aging, the lesson from Blue Zones and centenarians alike still rings true, a balanced diet, physical activity, meaningful social ties, and preventive healthcare remain the closest things we have to longevity secrets. The road to 150 may or may not be real, but the path to 100—healthy, independent, and vibrant—is already within reach.

At a military parade in Beijing, an open-mic moment between Chinese President Xi Jinping and Russian President Vladimir Putin revealed an unusual exchange. The leaders were overheard discussing organ transplants and the possibility of dramatically extending human life. Putin even raised the prospect of “eternal life” through biotechnology, according to translated remarks aired on Chinese state TV. The conversation, captured as Xi, Putin, and North Korean leader Kim Jong Un walked through Tiananmen Square, has fueled fresh debate on the limits of science and longevity. Both Xi and Putin, in power for 13 and 25 years respectively, have shown no signs of stepping down.The pageantry was meant to project strength, but a stray hot mic gave the world something unexpected: an intimate glimpse into how two of the most powerful men on Earth think about the human lifespan.Putin’s interpreter was caught saying, “Biotechnology is continuously developing. Human organs can be continuously transplanted. The longer you live, the younger you become, and even achieve immortality.” Xi responded, almost casually: “Some predict that in this century humans may live to 150 years old.”The microphones were quickly faded out, and the livestream camera cut away. But the brief exchange rippled far beyond the parade. Could 150 really be the ceiling for human life—or even a realistic milestone?What is The Hot Mic Moment?Both Xi and Putin later confirmed the conversation, with Putin remarking to Russian media that new medical advances, including organ replacement, could extend “active life” significantly. For leaders who have each been in power for more than a decade—and show no signs of stepping aside—the notion of extending life carries not just personal but political undertones.This wasn’t idle speculation in a vacuum. Russia, China, and the United States are all investing heavily in biotechnology, regenerative medicine, and artificial intelligence as tools not only of economic growth but also of national prestige.
