Common Questions About Health Span
What's the difference between health span and lifespan?
Lifespan is total years alive. Health span is years lived in good health — free from chronic disease, disability, and cognitive decline. The average American lives to 77 but spends the last 10-15 years in poor health. The goal of longevity science is compressing that gap — staying healthy longer, not just living longer.
What interventions actually extend health span?
The evidence supports: maintaining BMI under 30 (GLP-1 medications produce 15-22% weight loss), preserving growth hormone levels (Sermorelin stimulates natural GH production), supporting NAD+ levels (declines ~50% by age 50), regular exercise, sleep optimization, and stress management. This calculator estimates your gap and recommends which interventions match your profile.
Can I really add healthy years to my life?
Research shows lifestyle and targeted interventions can add 7-14 healthy years. The Harvard Adult Development Study found that physical health at 50 was a stronger predictor of health span than genetics. The interventions recommended by this calculator target the specific markers showing decline in your profile.
