The 7 Longevity Non-Negotiables
Why this guide exists — and how to use it
How long you live is only partly determined by genetics. How many of those years you spend in full physical and mental function — the distinction covered in Section 1 — is far more modifiable, and the tools that move it most reliably are, disappointingly for anyone hoping for a shortcut, mostly the unglamorous fundamentals covered elsewhere in this Archive. This guide covers the biology of aging itself, and applies the same scrutiny to emerging, exotic interventions as it does to everything else in this Archive.
This guide synthesises the peer-reviewed geroscience literature into one complete, readable document — drawing on the consensus hallmarks-of-aging framework from Carlos López-Otín and colleagues, the caloric restriction trial data from the CALERIE study, and the Interventions Testing Program's rigorous animal-longevity screening. It deliberately cross-references rather than re-derives the exercise, cardiovascular, and sleep fundamentals already covered in depth elsewhere in this Archive. Read it once end-to-end, then return to sections as reference.
The 7 Non-Negotiables
| # | Non-Negotiable | Why it matters |
|---|---|---|
| 1 | VO2 max is the strongest single objective predictor available | Moving from the lowest fitness category to just above it is associated with a roughly 45% reduction in all-cause mortality in large clinical cohorts. |
| 2 | Never stop resistance training | Muscle mass is one of the strongest independent predictors of healthy aging, and resistance training is the primary lever that slows its age-related decline. |
| 3 | Get the cardiovascular and metabolic fundamentals right | Blood pressure control is as impactful as any pharmacological longevity intervention currently being tested — see the Heart & Metabolic Health guide. |
| 4 | No exotic intervention outperforms not smoking | It remains the single most impactful action available to a smoker, with risk reduction beginning the day cessation starts. |
| 5 | Sleep consistently | Chronic poor sleep is among the strongest predictors of early death and disease in the epidemiological literature — see the Sleep guide. |
| 6 | Treat emerging interventions with genuine scientific humility | NAD+ precursors, rapamycin, metformin, and peptides all have real but incomplete evidence — none is a substitute for the fundamentals. |
| 7 | Measure before you intervene | Regular self-measurement — tracking real biomarkers over time — is the useful principle behind even the most expensive longevity protocols, and it's available to anyone. |
