Bryan Johnson, the longevity-focused tech investor, disclosed an incurable autoimmune gastritis that attacks the stomach lining, diagnosed after a long run of biomarker monitoring. He says he will press on with his intensive biohacking and health regimen to influence the outcome, even as experts warn the prognosis is bleak and no medical cure is currently available beyond management.
Bryan Johnson, the 48-year-old tech entrepreneur known for extreme health experiments, revealed he has autoimmune gastritis, an incurable autoimmune disease that attacks his stomach lining. He says the condition likely stems from years of fast food and sugary drinks before his biohacking regimen and plans to keep monitoring ferritin and iron levels, undergo repeated biopsies, and pursue new treatments with AI and biotech as part of his “don’t die” quest to extend healthspan.
A Vox-tied look at longevity highlights a potential dementia-reducing link from the shingles vaccine, but the practical core emphasizes four actions: stay socially connected to cut isolation-related risk, follow a Mediterranean-style diet for cancer/heart/cognitive benefits, engage in regular strength training to preserve muscle, and prioritize sleep—especially deep sleep—with a consistent schedule. The goal is to maximize healthy years (healthspan) rather than chasing an arbitrary longevity number, and it’s never too late to start.
A recent review tests the ‘selection shadow’ idea—that natural selection weakens after reproduction, allowing late-life mutations to accumulate and drive aging. By analyzing large human genetic datasets and cross-species aging data, the researchers find evidence for weaker late-life selection and identify conserved aging pathways, suggesting that interventions targeting upstream aging processes could compress morbidity and improve healthspan, not just extend lifespan.
Daily movement is the top longevity habit: you don’t need long workouts—brief bursts (even 2 minutes of vigorous activity) and NEAT practices like stairs, parking farther, or quick 5–10 minute sessions can raise your heart rate and extend healthspan, offering a low-risk, sustainable way to combat sedentary living.
In a 32-week, randomized trial of 108 adults with HIV-associated lipohypertrophy, weekly semaglutide reduced biological age by about 3.1 years on multiple epigenetic clocks and up to 5 years on the most sensitive ones, with DunedinPACE slowing by ~9%. The biomarker shifts correlated with reductions in inflammation and visceral fat, suggesting aging slows via metabolic effects rather than a direct anti-aging action. Limitations include population specificity and reliance on epigenetic biomarkers; broader trials are needed to determine applicability to the general population and real-world health outcomes.
Experts say six simple daily habits—consistent sleep, regular daily movement (NEAT), habit-stacked nutrition changes, a sense of purpose, strong social connections, and stress management—can extend healthy years and reduce disease risk, emphasizing that lifestyle choices matter more than pricey trends when it comes to aging well.
Kara Swisher's CNN series argues that extending healthy years matters more than lifespan, highlighting habits that boost healthspan—learning new, friction-filled activities, social interaction, and science-backed practices like fermentation—so people can thrive rather than just survive.
Americans want longer, healthier lives, but the US lags in healthspan due to lifestyle gaps; the piece argues for a deeper integration of social sciences—emotional motivation, relationships, and intrinsic goals—into medical practice and policy to spur lasting healthy behaviors, rather than relying on tech or drugs alone, drawing on long-running studies like Harvard to support this approach.
GLP-1 drugs, originally prescribed for type 2 diabetes and obesity, are being explored by healthy individuals in the hope of extending healthspan and possibly lifespan. The evidence is tantalising but not conclusive, and these therapies are far from a proven longevity panacea given uncertainties about long-term effects, risks, and costs.
Americans crave longer, healthier lives, but the real path is daily lifestyle choices—eating well, regular exercise, not smoking, moderate alcohol, enough sleep, hydration and social connections—rather than relying on medical advances or tech alone. The U.S. shows a widening gap between lifespan and healthspan, with genetics about 25% and lifestyle about 75% of longevity; despite optimism for future tech, chronic diseases and aging-related conditions persist due to inactivity, poor diet, isolation, and a treatment-focused system. A Medtronic/Morning Consult poll found 66% would trade longer life for a shorter, healthier one, while 84% still rate wellness as a top priority. The takeaway: small increases in activity, preventive care, and a positive mindset can add healthy years, proving that longer life should come with better health through sustained daily habits.
This Nature Aging review examines how different dietary restriction (DR) strategies—caloric, protein, fasting, and time-restricted regimens—affect aging and disease across mammals, highlighting common longevity pathways (autophagy, NAD+, AMPK, mTOR) and potential DR mimetics (FGF21, sirtuins, GLP-1). DR can improve healthspan and delay cancer, cardiovascular disease, and neurodegeneration in preclinical models, but effects vary by genotype, sex, species, and age at initiation, and DR may impair immune function and wound healing. The article discusses physiological adaptations (hunger, body temperature, fat loss) and translational challenges to humans, emphasizing the need for personalized approaches and cautious development of DR mimetics.
Longevity fitness shifts the narrative from chasing beach-ready bodies to maximizing healthspan by prioritizing muscle and aerobic fitness that support independence in older age; while the science supports these goals, the piece warns that much of the longevity hype rebrands existing products, cautions against over-tracking and inequality, and advocates a balanced approach: regular exercise, adequate sleep, solid nutrition, and stress management rather than pricey fads or quick fixes.
Emerging data suggest that a course of the shingles vaccine may slow ageing, reducing age-related health decline by about 20% across multiple countries and potentially lowering dementia risk.
A longevity-focused piece argues there’s no single secret to a longer life, but healthspan can be expanded by avoiding five common habits: sitting for long periods, regularly eating ultraprocessed foods (especially processed meats), isolating oneself, ignoring sleep problems, and skipping routine doctor visits. To counter these, experts recommend integrating movement (about 150 minutes of moderate activity weekly plus 2–3 strength sessions and 5–10 minutes of daily stretching), prioritizing social connections, addressing sleep disorders with medical care, and staying current with preventive care to catch issues early.
