Verified step by step guidance

1. Understand the concept of life expectancy: Life expectancy refers to the average number of years a person is expected to live based on various factors such as genetics, lifestyle, and environmental influences.
2. Identify the factors that significantly influence life expectancy: These include genetics (inherited traits and predispositions to diseases), sex (biological differences between males and females), and economic status (access to healthcare, nutrition, and living conditions).
3. Analyze the role of hair color: Hair color is determined by genetics but does not directly impact health, disease risk, or environmental factors that influence life expectancy.
4. Compare hair color to the other factors: While genetics, sex, and economic status have measurable effects on life expectancy, hair color is not associated with any significant health outcomes or life expectancy determinants.
5. Conclude that hair color is not a significant factor in influencing life expectancy, as it does not affect the biological, social, or environmental aspects of health.
