Frequently Asked Questions

How accurate is this calculator?

This calculator is for entertainment only. Actual life expectancy depends on genetics, healthcare access, environmental factors, and countless other variables that no simple formula can capture.

Where do the adjustment values come from?

The adjustments are rough approximations based on published epidemiological research on lifestyle factors and mortality. They represent averages and may not apply to individuals.

Why is smoking such a large factor?

Smoking is consistently shown to reduce life expectancy by about 10 years on average. It's one of the most significant modifiable risk factors for premature death.

Can I really add years by exercising?

Regular physical activity is associated with longer life expectancy in many studies. The effect varies, but active people tend to live 2-5 years longer than sedentary individuals.
