Key Longevity Factors
Our algorithm uses 12 validated predictors from studies like Framingham, UK Biobank, and Blue Zones:
- Genetics: 20–30% of lifespan (parental age at death)
- Lifestyle: 70–80% modifiable (diet, exercise, smoking)
- Socioeconomic: Education ↑ 7 years, income ↑ 5 years
- Biometrics: BMI 22–25 optimal, BP <120/80
Blue Zones Secrets
People in Okinawa, Sardinia, and Loma Linda live to 100+:
- Plant-based diet (95% calories)
- Natural movement (gardening, walking)
- Purpose in life ("ikigai")
- Strong social ties
- Moderate alcohol (wine with meals)
Impact of Habits
- Smoking: -10 to 15 years
- Obesity (BMI>30): -8 to 10 years
- Exercise (150 min/week): +3 to 7 years
- 7–8 hrs sleep: +5 years vs <6 hrs
- Mediterranean diet: +8 to 10 years
- Chronic stress: -2 to 5 years
Healthspan vs Lifespan
Lifespan = total years. Healthspan = years in good health.
Goal: Extend healthspan to match lifespan. Our tool predicts both.
Genetic vs Lifestyle
Even with "bad" genes, lifestyle can add 14 years (NEJM 2023 study).
How to Add Years
- Quit smoking: +10 years if before 40
- Exercise 30 min/day: +3.4 years
- Healthy BMI: +4 years
- Social connections: +50% lower mortality
- Learn continuously: +2.5 years per education level
Emerging Longevity Science
- Senescent cell clearance: +20% in mice
- NAD+ boosters (NMN): Human trials 2025
- Epigenetic clocks: Measure biological age
- AI predicts death within 5 years (90% accuracy)
Regional Disparities
US: 20-year gap between richest and poorest counties.
Education: College grads live 7 years longer than high school dropouts.
Science Facts
- Telomere length: +1 year per 1000 base pairs
- VO2 max: Top 25% live 5 years longer
