Question 1

How is my life expectancy calculated?

Accepted Answer

Our model combines data from WHO life tables, the Framingham Heart Study, and leading longevity research. We analyze 5 health dimensions — Cardio & Fitness, Metabolic Health, Sleep & Recovery, Cognitive & Emotional, and Genetics & History — to estimate your biological age and life expectancy.

Question 2

Is the life expectancy test really free?

Accepted Answer

Yes, completely free. No credit card, no hidden fees. You can take the questionnaire, see your full longevity score, biological age, and personalized recommendations without paying anything.

Question 3

What is biological age and how is it different from my real age?

Accepted Answer

Your biological age reflects how old your body actually is based on your lifestyle and health factors, while your chronological age is simply how many years you've been alive. Someone who exercises regularly, sleeps well, and eats healthy may have a biological age years younger than their real age.

Question 4

How long does the questionnaire take?

Accepted Answer

About 7 minutes. The questionnaire covers your demographics, lifestyle habits, health history, and optionally your biomarkers. You can skip any section and come back to edit your answers later.

Question 5

Is my health data private and secure?

Accepted Answer

Absolutely. Your data is encrypted and stored securely. We never share or sell your personal health information. You can take the test without even creating an account — your results stay on your device until you choose to save them.

Question 6

Can I really add years to my life?

Accepted Answer

Research shows that up to 80% of lifespan is determined by lifestyle, not genetics. Studies published in Circulation (2018) found that adopting five healthy habits could add up to 14 years of life expectancy. Our tool shows you exactly which changes would have the biggest impact for your specific profile.

Question 7

What are the 5 health dimensions you analyze?

Accepted Answer

We evaluate 5 core dimensions, each scored from 0 to 10: Cardiovascular (30%), Metabolic (25%), Sleep (20%), Cognitive (15%), and Genetics (10%). Under the hood, these are broken into 14 subcategories for precision — Exercise, Functional Fitness, Nutrition, Body Composition, Biomarkers, Sleep Quality, Stress Management, Social Bonds, Cognitive Health, Substance Use (smoking & alcohol), Mental Health, Family Genetics, and Chronic Disease History. Together they form your overall longevity score.

Question 8

How accurate is my longevity score and biological age?

Accepted Answer

We use peer-reviewed risk equations and actuarial data calibrated to your age, sex and country. While no tool can predict exactly how long you'll live, accuracy improves when you connect health-record data and complete the full questionnaire. The real value is in identifying which factors you can improve.

Question 9

Is Longevity Path a medical service?

Accepted Answer

No. We provide an evidence-based estimate of biological age and lifestyle factors. We are not a substitute for medical advice from a qualified clinician.

Question 10

Do I need a subscription?

Accepted Answer

The core questionnaire and your scores are free. Personalised improvement plans, document analysis and ongoing tracking are part of Longevity Path Pro.

Question 11

How is this different from a DNA test?

Accepted Answer

Genetics explain about 20% of lifespan. We focus on the 80% you can change — daily habits, biomarkers and clinical history — which DNA tests do not measure.
