💡 Real-Life Example
Let’s say you’re a 45-year-old female living in Japan. You maintain a healthy lifestyle and have a family history of long life.
- Base life expectancy: 75
- Gender (female): +5
- Country (Japan): +4
- Lifestyle (excellent): +5
- Family History: +3
Final estimate: 75 + 5 + 4 + 5 + 3 = 92 years
