Longevity and Cognitive Performance for Adults 40+ | Timeless Wisdom
Evidence-first · For adults 40+
Longevity, rated by the strength of its evidence.

Three guides that cover most of what matters
Best Evidence-Backed Longevity Interventions After 40
The current decision map for what deserves priority — what moves mortality, what moves healthspan, what only moves markers.
VO2max for Adults 40+: Protocols, Zones, and Progression
Why aerobic capacity predicts lifespan better than most risk factors, and the training hub to raise it.
Supplements for Longevity and Cognition: Ranked by Evidence
What belongs in, near, or outside a rational stack — the short list that survives scrutiny.
Editorial promise
Every claim carries its grade. Every grade carries its sources.
Core articles prioritize systematic reviews, meta-analyses, randomized trials and primary human evidence. Mechanistic or animal data are labeled as lower-certainty support. Whenever Pascal Marie shares what he does personally, it is labeled as self-experimentation and kept distinct from clinical evidence.
- StrongMultiple RCTs or large cohorts, consistent direction, plausible mechanism.
- ModerateGood trials with limits: small samples, short duration, surrogate endpoints.
- EmergingMechanistic or animal data, early human signals. Interesting, not yet actionable.
- SpeculativeUpside case only. The evidence ceiling is stated before the promise.
- Experimentn = 1. Personal protocols, logged and labelled so they never pass for evidence.

Longevity, genetics & uncertainty
MTHFR / COMT, rs4680, rapamycin, copper GHK — where the upside case must stay separate from the evidence ceiling.

About Timeless Wisdom
An evidence-first publication, not a hype feed.
It exists to help adults 40+ understand what the literature supports, what remains uncertain, and what tradeoffs matter before trying a protocol. Core articles carry a visible evidence rating, surface the main risk and contraindications near the top, and show review dates so readers know when a page was last checked.
