Longevity
Aging biology and the science of healthy lifespan.
Overview
Longevity science studies why we age and what extends healthspan — the years lived in good function — rather than merely lifespan. It integrates the evidence across every other body system.
Why it matters
Most of what reliably extends healthy life is unglamorous and well-proven: exercise, not smoking, metabolic and cardiovascular health, sleep, and social connection — while many marketed 'anti-aging' interventions are unproven.

Frequently asked questions
What's the most proven longevity intervention?
Physical fitness. Cardiorespiratory fitness and strength are among the strongest modifiable predictors of living longer and better.
Do anti-aging supplements work?
Most lack strong human outcome evidence. BioSignal rates them on the same honest scale as everything else — many are experimental or unproven.
