Interpreting Your Results
Understanding the Numbers
- Biological age: Your body's functional age
- Age difference: How much older/younger than your calendar age
- Category scores: Areas needing improvement
- Recommendations: Specific actions to take
What the Results Mean
Biological Age < Chronological Age:
- Your body is aging slower than expected
- Maintain your healthy habits
- Consider additional optimizations
Biological Age = Chronological Age:
- Your body is aging at the expected rate
- Room for improvement in some areas
- Focus on specific recommendations
Biological Age > Chronological Age:
- Your body is aging faster than expected
- Prioritize lifestyle changes
- Consider professional health guidance
Category Analysis
Each category provides insights into specific health areas:
- High scores: Areas needing attention
- Low scores: Strengths to maintain
- Average scores: Room for improvement
