Where:

• Age — Current age in years
• Sex — Biological sex (male/female)
• BMI — Body Mass Index (kg/m²)
• Smoking — Tobacco use status (yes/no)
• Country — Country of residence

Explanation: The model incorporates statistical data from population studies to estimate average life expectancy based on these key factors that significantly influence mortality rates.

3. Importance of Life Expectancy Estimation

Details: Understanding life expectancy helps with retirement planning, health decisions, and lifestyle changes. It provides insight into how various factors impact longevity.

4. Using the Calculator
