Lifestyle Factors

High Impact

Critical Longevity Factors

Research shows lifestyle habits can influence up to 80% of your biological aging process. These factors have the strongest impact on your longevity and healthspan.

Your Results

The Longevity Calculator blends data from major epidemiological studies with the latest aging research to estimate your potential lifespan and biological age.

How This Tool Works: We combine well-studied risk and protective factors—such as BMI, smoking, exercise, sleep, and biomarkers like CRP—in a scoring system derived from population-level research (e.g., WHO, CDC, Nurses' Health Study, various longevity cohorts). Each factor can shift your projected lifespan up or down.

Why You Can Trust It: The algorithms here are built from large epidemiological data sets and evidence-based "Hallmarks of Aging" science. We reference: Celis-Morales (grip strength), Li T (sedentary risk), Ridker (CRP/inflammatory markers), plus data from the CDC, WHO, and the Nurses' Health Study. While no calculator can be perfect, ours is transparent, continuously reviewed, and updated as new research emerges.

What the Results Mean: You'll see an estimated lifespan range (capped at 110 in this model) and a computed "Biological Age" that may differ from your real age. Lower biological age indicates a lifestyle & health profile typical of younger individuals; higher suggests room for improvement in certain areas.

This estimate is calculated using your biological markers, lifestyle factors, and statistical models from longevity research. It represents a potential outcome based on current factors, not a prediction.

Modifiable

Your estimated lifespan can change based on lifestyle improvements and health interventions.

Key factors

Diet quality, exercise frequency, sleep, stress management, and medical care all influence this number.

Precision

The estimate has a ±5 year margin based on the completeness of your data.

Scientific basis

Based on epidemiological studies, biological aging markers, and statistical modeling of health outcomes.

Looking good: Your estimate is within average range. Small improvements in your lifestyle could still add several healthy years.

What is Biological Age?

Biological age measures how well your body functions relative to your actual age. It's calculated from biomarkers like inflammation, metabolism, and cellular health.

Why It Matters

Your biological age is a stronger predictor of longevity and disease risk than your chronological age. Lifestyle changes can help reduce your biological age over time.

About Confidence & Accuracy

Biological age calculations include a natural uncertainty range (±3 years). Complete data in all fields improves accuracy. Critical markers for precision include: exercise levels, sleep quality, inflammatory markers (CRP), and metabolic health indicators.

Hallmarks of Aging

Based on the "Hallmarks of Aging" framework from longevity science, here's how your profile affects key aging mechanisms:

Areas to Improve:

Not enough fasting or cardio intensity to boost autophagy.

Suggestion:

Try intermittent fasting (>12 hrs) or high-intensity cardio to support autophagy.

Potential Gains

Here are a few tweaks you could make to potentially raise your lifespan or reduce your Bio Age even further:

Optimize Sleep Duration

+1 years

Increasing sleep from your current hours to 7-8 hours can potentially add ~1 year to your lifespan.

Vitamin D Supplementation

+0.5 years

Regular vitamin D supplementation supports immune function and may reduce all-cause mortality.

Gut Microbiome Support

+0.5-1 years

Adding 1 daily serving of fermented foods can improve gut health and reduce inflammation.

Increase Exercise Frequency

+1-3 years

Aim for at least 3-4 days of exercise per week to reduce mortality risk by ~20-30%.
