Bryan Johnson

Entrepreneur & Biohacker

Bryan Johnson **revolutionizes human optimization** by treating his body as a startup ripe for disruption, pouring $2 million annually into the **Blueprint protocol**—a data-driven algorithm that slashes his biological aging to just 277 days per year.[1][3][5] From the ashes of chronic depression, nightly overeating, and entrepreneurial burnout after selling Braintree (and Venmo) to PayPal for $800 million, Johnson pivots boldly.[1][2][3] He emerges as the **most measured human in history**, tracking every biomarker across 70+ organs with MRI scans, blood tests, and brain interfaces from his company Kernel.[3][4][6] His **breakthrough insight**: Trust algorithms over intuition. Blueprint synthesizes thousands of scientific studies into precise protocols—vegan fueling with three meals ending at 11 a.m., 100+ supplements, shockwave therapy, stem cell injections, and plasma exchanges—that deliver jaw-dropping results: a heart functioning like a 37-year-old's (at age 45+), inflammation 66% below a 10-year-old's, 80% less gray hair, perfect liver fat, and 18-year-old fitness levels.[1][5][6] Johnson **democratizes longevity**, sharing every recipe, workout, and dataset for free online, inspiring biohackers worldwide to reverse epigenetic age by 5.1 years without his budget.[3][5] He funds family experiments, like multi-generational plasma swaps that shaved 25 years off his father's biological clock using his "super blood."[5] Through Blueprint's $60 million raise from Silicon Valley elites, he scales **practical tools**—olive oils, supplements, fasting windows (10-16 hours)—that anyone applies for sharper cognition, faster recovery, and peak physicality.[3][5][7] In Johnson's world, death becomes optional. He **rewrites life's OS**, proving quantified self-tracking and protocol optimization unlock god-like performance, fueling consciousness expansion and radical life extension for all.[2][3][5]

David Sinclair

PhD, Professor of Genetics

# David Sinclair: The Scientist Proving Aging Is Reversible David Sinclair doesn't just study aging—he's dismantling the assumption that it's inevitable. As a tenured Professor of Genetics at Harvard Medical School and co-director of the Paul F. Glenn Center for Biology of Aging Research, Sinclair has spent over two decades uncovering the biological mechanisms that make us old, and more importantly, how to reverse them[1][3]. His revolutionary insight reshapes everything we thought we knew about human potential: **aging isn't written in stone—it's written in our epigenetics, and that code can be rewritten**[4]. This isn't theoretical. In 2020, Sinclair's lab made headlines by using epigenetic reprogramming to reverse vision loss in aged mice with glaucoma, demonstrating that tissue regeneration and functional restoration are possible in living organisms[4]. By 2023, his team published landmark research in *Cell* proving that loss of epigenetic information causes aging and that these changes are reversible[4]. The practical foundation of Sinclair's work centers on **NAD+ metabolism and sirtuins**—protein-modifying enzymes that act as cellular guardians responding to caloric restriction and metabolic stress[1][2]. His lab was the first to identify NAD+ biosynthesis as a regulator of lifespan and to show that sirtuins activate in response to caloric restriction in mammals[2]. He's identified molecules like resveratrol that activate SIRT1, opening doors to interventions that improve metabolic function without requiring extreme lifestyle changes[2]. For biohackers and health optimizers, Sinclair's work translates into actionable strategies. He personally practices intermittent fasting (16-18 hours between meals), prioritizes polyphenol-rich foods, and has eliminated dairy and alcohol—changes that he reports have dramatically improved his blood biomarkers and epigenetic age within months[8]. His research validates that what you do in your twenties matters; the epigenetic clock starts ticking from birth[8]. Beyond the lab, Sinclair has co-founded eight biotechnology companies and serves as co-founder and co-chief editor of the journal *Aging*, shaping how longevity science reaches the world[2]. Named one of TIME's 100 Most Influential People, his work has fueled a multi-billion-dollar industry focused on treating age-related diseases and extending healthy human lifespan[5]. Sinclair's core message is radical in its optimism: **aging is not destiny—it's a disease we can treat**[1]. For anyone serious about optimizing their health, cognition, and longevity, his research provides both the scientific foundation and the practical roadmap.

Peter Attia

MD, Longevity Expert

Dr. Peter Attia revolutionizes longevity medicine by championing **Medicine 3.0**, a proactive framework that shifts focus from treating diseases to preventing them, compressing morbidity into the shortest possible window so you thrive robustly into your final decade.[2][3][5] As founder of Early Medical, he applies cutting-edge science to elite patients, blending nutritional ketosis, intermittent fasting, and hyper-optimized exercise to supercharge metabolic health and cellular repair.[1][2] Attia pioneers the insight that aging isn't inevitable decline—it's a metabolic war won through his **Five Pillars of Longevity**: exercise, sleep, nutrition, emotional health, and targeted pharmaceuticals or supplements.[2][7] He logs 10 hours weekly of cardio, VO2 max intervals, and strength training himself, proving exercise trumps any pill for preserving muscle, torching fat, and safeguarding cognition.[3] His breakthrough? Recognizing mitochondria's starring role in aging; by fueling them with ketosis and fasting, you unlock energy reserves that fend off cancer, diabetes, and neurodegeneration.[1][2] Through his blockbuster book *Outlive*—selling nearly 3 million copies—and *The Drive* podcast, downloaded over 100 million times, Attia demystifies science for biohackers worldwide.[3][6] He co-founded NuSI to dismantle obesity myths, advancing nutrition research that empowers personalized protocols.[2][6] Dropping residency for McKinsey honed his systems-thinking; NIH research on immunotherapy extended cancer survival, fueling his quest for 1.5-2 extra healthy decades.[2][4] For biohackers, Attia delivers actionable gold: time-restricted eating stabilizes insulin, rucking builds zone 2 endurance for peak performance, and emotional work—honed through his own therapy—sharpens consciousness amid stress.[1][3] He equips you to outpace aging, turning longevity into a high-performance edge that billionaires and everyday optimizers chase. Dive into his world; your vital decade awaits.[3][5]
