1. What is Life Expectancy Estimation?

Life expectancy estimation provides a statistical prediction of how long a person is expected to live based on current age, health status, and lifestyle factors. This calculator uses a simplified model based on population statistics and health research.

2. How Does the Calculator Work?

The calculator uses a predictive model:

Where:

• \( B \) — Base life expectancy for current age
• \( A \) — Age adjustment factor
• \( H \) — Health score (1-10)
• \( L \) — Lifestyle score (1-10)
• \( S \) — Lifestyle multiplier
• \( R \) — Risk factors
• \( M \) — Risk multipliers

Explanation: The model accounts for current health status, lifestyle choices, and typical age-related decline patterns.

3. Factors Affecting Life Expectancy

Key Factors: Genetics (20-30%), lifestyle choices (50-60%), environment (10-20%), and healthcare access (10-20%).

4. Using the Calculator

Tips: Be honest about your lifestyle and health status. The calculator provides general estimates - individual results may vary.
