Starts from country/sex baseline life expectancy then adjusts for smoking, exercise, diet, BMI from height/weight, and alcohol. Not a medical prediction.
Quick answer: Life Expectancy Calculator
Country/sex baseline LE adjusted by smoking, exercise, diet, BMI, and alcohol heuristic deltas.
Example: Quitting smoking might add multiple expected years in the model versus continuing smoker path.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Outputs are statistical fictions for education; individual genetics and accidents dominate variance.
