Learn to spot what a longevity headline leaves out.

Start with an orientation to the field, then move through shared language, safety questions, evidence, trials, and biomarkers. Each guide preserves what is unknown instead of compressing it into a score.

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.

New research-literacy explainer

Put a relative percentage back on an absolute scale

Absolute risk shows what relative risk leaves out uses SPRINT and ASPREE to show how baseline risk, denominator, follow-up and uncertainty change a trial headline’s meaning.

Eleven practical starting points

What are you trying to figure out?

Begin with Evidence at a glance when you want to compare outcomes across released stories. Use Longevity 101, the glossary, and the safety framework for orientation.

Guide 11 · Search

Where have we covered that word or outcome?

Search all 66 released stories by ordinary words and governed evidence labels, with relevance kept separate from evidence strength or recommendation.

Guide 01 · Orientation

What is longevity research?

Map aging biology, interventions, evidence, and decisions before translating a result into meaning.

Start with Longevity 101
Guide 02 · Vocabulary

What does that term mean?

Use stable plain-language definitions and keep biomarkers, endpoints, healthspan, and lifespan distinct.

Open the glossary
Guide 03 · Safety

What deserves a closer look?

Check claims, evidence, identity, and pressure independently without turning warning signs into an automatic verdict.

Use the safety framework
Guide 04 · Evidence

How strong is the evidence?

Move from cells and mechanisms through animal, observational, randomized, and replicated human evidence without treating the ladder as a score.

Read the evidence ladder
Guide 06 · Biomarkers

What does the measurement mean?

Separate repeatable measurement from association, validation, surrogate status, function, healthspan, and lifespan.

Read the biomarkers guide
Guide 07 · Methods

How was the question tested?

Separate design, execution, analysis, reporting, replication, and practical relevance before judging a result.

Read the research-methods guide
Guide 08 · Translation

Will a result transfer to people?

Compare model fit, exposure, outcome, duration, population, and safety without turning similarity into proof.

Read the translation guide

A useful reading habit

Four tests every longevity claim should pass.

Evidence maturity

How close is the evidence to the outcome readers care about?

A mechanism, a human association, and a replicated clinical outcome answer different questions.

Study quality

Was the question tested in a way that limits bias?

Design, execution, missing data, reporting choices, and independent replication all matter.

Practical meaning

Is the measured change meaningful for people?

A detectable signal is not automatically a change in function, healthspan, or lifespan.

Personal relevance

Does the evidence apply to this population and decision?

Population, setting, duration, tradeoffs, and clinical context cannot be inferred from a headline.
