How Stanford's longevity researcher reversed his biological age by 10 years
Longevity researcher Dr David Furman didn't just study ageing—he lived it in reverse.
Ten years ago, life in a bustling California city had taken its toll. 'My life was pretty stressful,' Dr Furman admitted in an interview with Business Insider recently. Headaches were routine. Ibuprofen was a crutch. He suspected his fast-paced, urban lifestyle was doing more than just giving him migraines—it was speeding up his biological ageing.
To test this, the head of Stanford's 1000 Immunomes Project for the last 13 years ran a series of blood tests on himself. What he discovered shocked him. Though his biological age was 39, the inflammation in his body told a different story: he had the inflammatory profile of a 42-year-old man.
Faced with this sobering reality, he packed up his life and moved into the woods.
In 2016, Dr Furman, his wife, and their two children relocated to a modest two-bedroom cabin tucked away in the San Gregorio forest of Northern California, just half an hour from Stanford. This was no glamping getaway. Their home had no plastic furniture, industrial cleaners, or WiFi. Chairs were absent. Even bright overhead lights were switched off by 7:30 p.m., replaced with the soft glow of candlelight.
What began as an experiment turned into a transformative way of living. Over three years, his lifestyle began to reverse the toll that stress had taken on his body. Remarkably, he was able to de-age his biology by 10 years.
Does science back this approach? According to Dr Manisha Arora, Director of Internal Medicine at CK Birla Hospital in Delhi, there is certainly a rationale behind his results.
'Dr David Furman's story is certainly fascinating. The idea that he could 'de-age' himself simply by moving to a more serene environment and making lifestyle changes is inspiring. However, it's important to view this as anecdotal evidence rather than a universally applicable solution,' says Dr Arora.
The link between chronic stress and accelerated aging is well-documented. Stress increases cortisol levels, which over time damages cells, impairs immunity, and speeds up inflammation—all hallmarks of aging. Dr Arora explains:
'Living in a peaceful, natural setting can indeed lower cortisol levels, which has been linked to slower biological aging.'
Furthermore, the professor's lifestyle overhaul wasn't limited to meditation and fresh air. The Furman family cut out processed food, ate clean, home-cooked meals, and embraced movement naturally through hiking and outdoor activity.
'Good sleep, a balanced diet, regular physical activity, and stress management are the four pillars of healthy aging,' Dr Arora continues. 'Adopting habits supporting these areas can reduce biological age markers like inflammation, insulin resistance, and hormonal imbalances.'
Even the couple's practice of switching to candlelight in the evenings had physiological benefits. Reducing exposure to artificial light helps regulate circadian rhythms—important for deep, restorative sleep, another key to longevity.
Dr Arora quickly acknowledges that not everyone can escape to the forest.
'While these practices are beneficial, implementing such a drastic lifestyle change may not be feasible for everyone. Completely avoiding electronics, plastics, or modern conveniences may not be practical or sustainable in today's fast-paced world.'
But the bigger message from Dr. Furman's journey is this: environment matters. Even small, consistent shifts—like switching off screens earlier, eating fewer processed foods, or walking daily in green spaces—can help our bodies age better.
'The key takeaway,' Dr Arora says, 'is that making small, consistent lifestyle changes in the areas of stress, diet, sleep, and exercise can still have a meaningful impact on one's biological age and overall health.'

How rankings lead to the rise of academic commodification
Academic brilliance was once defined by the depth of scholarship, rigorous institutional processes, and a culture of inquiry nurtured by universities. Today, the focus has shifted to metrics, badges, and rankings. Institutions showcase it, scholars highlight it, and stakeholders treat it as a seal of quality. Yet, as with all that glitters, one must ask: what lies beneath? Today, Stanford is gaining recognition, alongside THE and QS rankings, despite the inherent flaws in all three. The Stanford ranking, for instance, seeks to identify the top 2% scientists in various disciplines based on a composite indicator. This includes bibliometric indicators such as total citations, h-index, co-authorship-adjusted metrics, and citations to papers in different authorship positions. While it appears scientific and data-driven, the exercise is not without flaws. For one, it depends entirely on Scopus data, a commercial database that does not cover all disciplines equally. Humanities and some Social Sciences are grossly underrepresented, leaving a large swath of global academia invisible in the analysis. Moreover, the focus on citation-based metrics incentivises quantity over quality. A well-written, widely-cited review paper can push a researcher up the ranks, while a game-changing monograph in philosophy may not even register. What makes it even more problematic is the blind application of these rankings by institutions. Without context, nuance, or disciplinary sensitivity, they are turned into marketing tools. It is less about a commitment to excellence and more about optics and prestige. The ranking becomes currency; a transactional marker to attract funding, students, and media attention. Indian context In India, the situation is more troubling. The National Assessment and Accreditation Council (NAAC) has come under intense scrutiny after the recent revelation of a university in Andhra Pradesh allegedly paying crores to secure an A++ grade. Shockingly, nearly 20% of NAAC assessors were later removed due to various irregularities. The demand for a comprehensive probe into the assessments conducted by these discredited evaluators is reasonable and urgent. In recent years, many institutions have managed to secure top grades, which many argue is inconsistent with the ground reality of poor infrastructure, faculty shortages, and abysmal student outcomes. This raises a troubling question: Have we reduced institutional quality to a game of strategic networking, financial leverage, and performative documentation? One cannot ignore the systemic pressures at play. The increasing corporatisation of academia has introduced market logic into the university system. As public funding shrinks, universities — especially private ones — are forced to rely on student fees and external rankings to remain afloat. This leads to a dangerous feedback loop. To attract students, institutions ease academic regulations, reduce penalties for indiscipline, and adopt student-centric policies that often border on appeasement. Faculty, burdened with teaching, administrative tasks, and publication requirements, face burnout. In such an environment, rankings become not just desirable but necessary. They are wielded as shields in an ever-intensifying battle for survival. Institutions chase Scopus-indexed journals to meet regulatory demands, not for the love of scholarship. Researchers pay exorbitant fees to get published and, when that fails, some resort to unethical practices, only for their papers to be retracted later. Flawed model In this matrix of manipulation, it is easy to blame the institutions. But the deeper malaise lies in the very education model we have embraced: one that equates visibility with value, metrics with meaning, and reputation with reality. Awards, too, have not been spared. Today, one can pay a tidy sum and receive an 'Excellence in Research' award in a foreign country with a sightseeing tour and conference pass thrown in. These packages are marketed as academic opportunities but are, in truth, commodified experiences engineered to inflate CVs. We must ask: did our finest institutions of yesteryear depend on such scaffolding? The situation may seem bleak, but not hopeless. To reverse the tide, we need to recalibrate our priorities. First, we must advocate for more context-sensitive and peer-reviewed models of assessment that go beyond metrics. Second, public funding for education must be restored and enhanced. The commodification of education is not an inevitable outcome; it is the result of deliberate policy choices. Third, academia must reclaim its soul. Universities are not businesses, and education is not a product. Rankings can be tools, but they must not become our tyrants. The rot will deepen until we resist the seduction of easy prestige and short-term gains. It's time to stop asking how to climb the ranks and start asking how to make learning meaningful again.

41-year-old doctor claims to be biologically 24, reveals the three ‘core' supplements behind his age reversal
Dr Mohammed Enayat, a 41-year-old primary care doctor based in London, claims that his biological age is just 24 — 17 years younger than his chronological age. The founder of the longevity-focused Hum2n clinic says he's been tracking his health for seven years using wearables, along with frequent blood, urine, and microbiome testing. 'While I believe these supplements have supported my biological age reversal, I credit them as one component in a much broader framework,' Dr Enayat told Business Insider, pointing to daily doses of 'core' supplements such as vitamin B complex with folate, magnesium, and omega-3 fatty acids as part of his routine. Dr Enayat said he takes vitamin B complex and folate due to a methylation gene defect that causes elevated homocysteine levels, which raises the risk of heart attack and stroke. 'Even without a methylation-related gene defect, I would still consider taking a methylated B complex, particularly during periods of high stress, poor sleep, or intensive training, as these increase the demand for B vitamins,' he added. On magnesium, he opts for bisglycinate due to better absorption, reporting reduced muscle aches and better sleep. For omega-3 fatty acids, he supplements due to low levels and notes their potential anti-ageing and anti-inflammatory effects. speaks to an expert to verify the efficacy. Dr Jagadish Hiremath, public health intellectual, says, 'Biological age tests such as GlycanAge and TruAge PACE can offer some insight into the impact of lifestyle, stress, and inflammation on the body's physiological state. These tests generally evaluate biomarkers correlating with cellular ageing or immune function, which differs from traditional diagnostics.' However, he adds that while the science behind these tools is evolving, they are not yet universally standardised across populations. Their interpretation requires nuance and should not be viewed as standalone indicators of health or risk. 'For the average person, these tests can serve as a supplementary checkpoint, but health decisions should still be grounded in regular clinical assessments and evidence-based screenings,' states Dr Hiremath. Methylated B vitamins are more bioavailable forms, Dr Hiremath informs, particularly helpful for individuals with genetic variations such as MTHFR polymorphisms. 'For those without such variants or a clinically diagnosed deficiency, taking a B complex occasionally during periods of high stress is unlikely to be harmful, but over-supplementation is unnecessary and may cause side effects in some cases, such as headaches or gastrointestinal upset,' he explains. The key is mindful dosing and timing. Vitamins should support a balanced diet, not replace it. If someone is considering supplements during stressful periods, a conversation with a healthcare provider can ensure the approach is both safe and targeted. Dr Hiremath says, 'Magnesium and omega-3 fatty acids are among the most researched and commonly used supplements with benefits ranging from cardiovascular health to sleep support. However, their necessity should ideally be determined by assessing dietary intake, lifestyle habits, and individual health needs.' Blood tests can identify deficiencies, but even in their absence, some individuals, such as those with sleep issues or limited fish intake, might benefit from short-term supplementation. The goal should always be to supplement if needed, not as a blanket solution for everyone. Finally, Dr Hiremath asserts, 'Supplements can play a supportive role, but they are just one piece of the puzzle. A complex interplay of factors, including genetics, nutrition, physical activity, sleep, stress management, and social connection influences longevity.'

6 worst habits that could be harming your looks: Harvard liver specialist urges to stop these lifestyle mistakes
Looking younger isn't just about skincare or genetics—it's also about the daily habits that shape your overall health. Dr. Saurabh Sethi, a liver specialist trained at Harvard and Stanford, recently shared science-backed advice on how certain lifestyle choices can speed up the aging process. From what you eat to how you manage stress, these factors can directly impact how old you look and feel, having broader implications for long-term health. In a YouTube video, Dr. Sethi outlined six habits that could be making you age faster—and what you can do to reverse the damage. Smoking: The Fast Track to Premature Aging According to Dr. Sethi, smoking tops the list as the most damaging habit when it comes to accelerating the aging process. It harms the skin's elasticity and reduces blood flow, leading to early wrinkles and a dull complexion. More importantly, it introduces harmful toxins that impact overall organ health, including that of the liver. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like If You Eat Ginger Everyday for 1 Month This is What Happens Tips and Tricks Undo Excessive Alcohol Consumption Drinking too much alcohol is another major factor that contributes to visible signs of aging. Alcohol dehydrates the skin, causes inflammation, and can damage liver function over time. While occasional consumption might not be harmful, consistent overindulgence can lead to long-term effects on both appearance and internal health. Poor Sun Protection While sunlight is essential for vitamin D synthesis and general well-being, Dr. Sethi emphasized that unprotected exposure during peak hours—especially from 10 a.m. to 4 p.m.—can speed up skin aging. Failing to use sunscreen or wear protective clothing like hats can result in sunspots, fine lines, and an overall older look. He advised mindful sun exposure and proper protection as crucial for maintaining youthful skin. Chronic Dehydration Maintaining proper hydration is especially important during warmer months, Dr. Sethi noted. Insufficient water intake leads to dry, sagging skin and an overall tired appearance. Staying hydrated supports skin elasticity and brightness, helping people look and feel younger. High Intake of Processed Foods and Sugar A diet filled with sugary and processed foods not only impacts metabolism but also contributes to skin problems and inflammation. Dr. Sethi pointed out that excess sugar can damage collagen, a protein responsible for skin firmness, which leads to premature aging signs like sagging and wrinkles. Unmanaged Stress Dr. Sethi also highlighted chronic stress as a silent contributor to aging. Long-term stress can disrupt hormonal balance, affect sleep, and leave visible marks on the face. He shared that he personally practices "Bhramari Pranayama"—a type of yogic breathing known as the humming bee breath—to manage stress and improve overall wellness. Such breathing techniques can help calm the mind and improve emotional well-being. Dr. Sethi's message is clear: Small but consistent lifestyle changes can go a long way in preserving both youthfulness and internal health. From quitting smoking to practicing stress-reducing techniques, these evidence-based suggestions aim to help people age gracefully—inside and out.
