Frequently Asked Questions (FAQ)

How accurate are life expectancy calculators?

Our calculator provides estimates based on statistical models from population studies and actuarial data. While individual results may vary, the projections are directionally accurate for identifying risk factors and improvement opportunities. No calculator can predict exact lifespan due to unforeseen events.

What factors most impact longevity?

Key longevity factors include: genetics (20-30%), smoking status, body weight, physical activity, blood pressure, cholesterol levels, diet quality, alcohol consumption, and chronic disease management. Our calculator weights these factors appropriately.

Can I improve my life expectancy estimate?

Absolutely. Research shows that adopting healthy behaviors even later in life can add significant years. Regular exercise, maintaining healthy weight, not smoking, managing stress, and preventive healthcare can potentially add 5-10 quality years to your lifespan.

What's the difference between lifespan and healthspan?

Lifespan refers to total years lived, while healthspan refers to years lived in good health, free from serious disease or disability. Our calculator helps optimize both through targeted recommendations for healthy aging.
