New evergreen guide

Start with the foundations before the hacks

10 things you can do for a longer, healthier life separates clinical outcomes, function and risk-factor evidence from claims about slower aging or added lifespan.

Learn the map

From first principles to real interventions

Begin with the field, an everyday category, drugs and supplements, or experimental translation.

Path 01

New to longevity science

Learn the map, then practice separating evidence maturity from a headline.

  1. Start

    What is longevity research?

    Start with the vocabulary and the layers that connect a result to a reader-facing claim.

    Orientation guide · Field map and core distinctions
  2. Next

    How strong is the evidence?

    Next, see why a mechanism, biomarker, association and clinical outcome answer different questions.

    Evidence guide · Cells, animals, human studies and outcomes
  3. Then

    Exercise and healthy aging

    Apply those distinctions to a mature human evidence base without turning broad benefit into a lifespan guarantee.

    Evidence explainer · Human function, disease risk and mortality
  4. Compare

    Partial reprogramming reaches a human safety trial

    Finish by contrasting that mature evidence with a genuinely experimental program.

Path 02

Everyday life

Move from a broad category to studies of exercise, mobility and eating patterns.

  1. Start

    Everyday foundations

    Start with the complete category so a single study does not stand in for the whole evidence base.

    Topic hub · Exercise, sleep and eating patterns
  2. Next

    Exercise and healthy aging

    See the broad human evidence and the boundary between healthier aging and proven lifespan extension.

    Evidence explainer · Human function, disease risk and mortality
  3. Then

    Physical activity and late-life mobility

    Narrow the question to one randomized program and one concrete functional outcome.

    Research analysis · Mobility disability in at-risk older adults
  4. Compare

    The randomized MIND diet trial

    Compare a different everyday intervention where the active control changed what the result means.

Path 03

Drugs & supplements

Compare null, mixed and early signals without treating category membership as endorsement.

  1. Start

    Drugs & supplements

    Start with the category boundaries, safety notes and complete released coverage.

    Topic hub · Seventeen published evidence reviews
  2. Next

    Omega-3 cardiovascular evidence

    See why results from unlike formulations and populations should not be collapsed into one verdict.

    Evidence explainer · Different formulations and cardiovascular outcomes
  3. Then

    Vitamin D and the VITAL trial

    Separate an essential nutrient and deficiency care from a broad prevention claim.

    Claim check · Primary prevention in generally healthy adults
  4. Compare

    Rapamycin and the PEARL trial

    Finish with an intervention whose human longevity evidence remains early and limited.

Path 04

Experimental science & aging measurements

Follow the translation chain from models and measurements to bounded human claims.

  1. Start

    From models to people

    Start with the questions that determine whether a model result can transfer to people.

    Translation guide · Cells, organisms, exposure, outcomes and safety
  2. Next

    How to read an aging biomarker

    Then separate a measurable change from a validated health outcome.

    Measurement guide · Validity, surrogacy, function and lifespan
  3. Then

    Partial reprogramming reaches a human safety trial

    Apply the translation questions to an experimental biotechnology entering human study.

    Research analysis · Early human safety testing and animal evidence
  4. Compare

    What epigenetic clocks can—and cannot—measure

    Finish with a measurement story where prediction and proven intervention benefit remain distinct.

Start with an outcome

Start with the outcome you care about

These sequences keep unlike outcomes and study designs separate. Position shows reading order only.

Path 05

Heart and circulation

Compare cardiovascular events, mortality and prevention settings without turning one result into a universal recommendation.

  1. Start

    SPRINT reduced cardiovascular events—not aging itself

    Start with a trial that measured cardiovascular events and mortality in a defined high-risk population while also recording treatment harms.

    Research Analysis · Human clinical outcomes · large randomized trial
  2. Next

    ASPREE did not lower cardiovascular events—and increased major bleeding

    Compare a different primary-prevention population where the cardiovascular result was null and major bleeding increased.

    Evidence Explainer · Human cardiovascular and safety outcomes · large randomized trial
  3. Then

    Statin evidence changes with age, risk and prevention setting

    Then see why primary versus secondary prevention, age and baseline risk change what the evidence can support.

    Evidence Explainer · Human clinical outcomes · trials and pooled evidence
  4. Compare

    Menopausal hormone therapy treats symptoms. WHI did not show a longevity benefit

    Finish with a long mortality follow-up that keeps symptom treatment, disease outcomes and general longevity prevention separate.

Path 06

Brain and cognition

Keep cognitive tests, dementia outcomes and subgroup findings in their proper lanes.

  1. Start

    FINGER slightly improved cognitive-test scores. It did not prove dementia prevention

    Start with a randomized cognitive-test result and the boundary between a measured score and dementia prevention.

    Research Analysis · Human cognitive tests · randomized multidomain trial
  2. Next

    Cognitive training improved practiced skills—not survival or proven dementia prevention

    Compare practiced abilities with disputed secondary dementia findings and a separate null mortality result.

    Evidence Explainer · Human trained abilities and long-term outcomes · randomized trial plus disputed secondary analysis
  3. Then

    Shingles vaccines prevent shingles. Dementia evidence remains non-randomized

    Next, separate randomized evidence for shingles prevention from non-randomized evidence about dementia outcomes.

    Research Analysis · Human disease outcomes · randomized and non-randomized evidence
  4. Compare

    Hearing intervention did not slow cognitive decline across the full ACHIEVE trial

    Finish with a null overall cognitive result whose higher-risk subgroup signal requires confirmation.

Strength, bones and independence

Separate bone density, fractures, mobility disability and physical-function tests.

  1. Start

    Testosterone did not prevent fractures in TRAVERSE

    Start by seeing why a bone-density change cannot substitute for the clinical fracture outcome.

    Zoledronic acid reduced fractures in osteoporosis—not aging itself

    Compare an osteoporosis trial that measured vertebral and hip fractures directly while retaining population and safety limits.
