// The Science

Biological Age ≠ Chronological Age

Depending on lifestyle, your cells can be 10–20 years older or younger than your passport age — and this is measurable

25–30%

Genetics

Share of longevity variation explained by genetics. Less than most people assume.

10+ yrs

Smoking impact

Estimated reduction in lifespan from chronic smoking

40–50%

Mortality reduction

Risk reduction from moving 'low' to 'above average' cardiorespiratory fitness

8–12 yrs

Morbidity gap

Average years of poor health at end of life in Western countries

Measurable Impact

Genetics Is Only 25-30%

Genetics account for approximately 25-30% of longevity variation according to twin studies — less than most people assume. Lifestyle factors dominate, especially when maintained across decades. What gets measured, gets managed. Our tools help you track the 70% that's within your control.

// Why it matters

Why Longevity Calculators?

Modern longevity science has advanced beyond simple lifespan estimates. Biological age — how old your cells actually are — can differ from your chronological age by 10–20 years depending on your habits. What gets measured, gets managed.

Our tools are based on peer-reviewed research from Bryan Johnson's Blueprint protocol, the Hallmarks of Aging framework, and validated biomarker studies including the GrimAge and DunedinPACE epigenetic clocks.

// What the tools offer

Evidence-Based & Privacy-First

Based on validated longevity science

Inputs and weights are derived from published studies on VO₂ max, epigenetic clocks, sleep research, and dietary biomarker data.

No data stored — runs in your browser

All calculations happen client-side. Nothing is transmitted or stored. Your health data stays private.

Actionable, personalised recommendations

Results include specific, ranked recommendations based on your inputs — not generic advice.

Frequently Asked Questions

Not smoking (adds 10+ years), regular physical activity (strength training + Zone 2 cardio), sleep quality (7–9 hours), plant-rich diet, social connection, managing metabolic health (blood glucose, insulin sensitivity), and regular preventive screening.

Lifespan is total years lived. Healthspan is years lived in good health — free from chronic disease, cognitive decline, and disability. The goal of longevity medicine is compressing morbidity: living healthily as long as possible and minimising the period of decline at the end.

This is actively debated. The oldest verified human was Jeanne Calment (122 in 1997). Some researchers believe 115–120 is approximately the natural maximum; others argue biomedical advances — senolytics, epigenetic reprogramming, and AI drug discovery — could push this substantially further within decades.

Genetics account for approximately 25–30% of longevity variation according to twin studies — less than most people assume. Having long-lived grandparents is a positive signal but not determinative. Lifestyle factors dominate, especially when maintained across decades.

Animal studies consistently show caloric restriction (CR) and intermittent fasting extend lifespan — in mice by 30–40%. Human evidence is less clear but shows metabolic improvements. Time-restricted eating (16:8) shows promising benefits for insulin sensitivity and inflammation markers.

Zone 2 is low-intensity sustained aerobic exercise (talking but slightly breathless, 60–70% max heart rate). It maximises mitochondrial function and VO₂ max improvements. Research consistently shows VO₂ max is the strongest predictor of all-cause mortality — stronger than any other lifestyle biomarker.

Indirect measures accessible at home: VO₂ max estimate (from fitness trackers), grip strength (dynamometer), resting heart rate, and HRV. For clinical-grade biological age, epigenetic clock tests (TruAge, SirenDx) require a blood or saliva sample but give the most validated estimate at ~$200–400.

Strongest evidence: Vitamin D (if deficient), Omega-3 fatty acids (EPA/DHA), Magnesium. Promising but less proven: NMN/NR (NAD+ precursors), Berberine (metabolic health), Rapamycin (longevity in animals; human trials ongoing). The evidence base varies enormously — lifestyle changes outperform all supplements.
