Longevity Can Save America

65+ = 18% of population, 36% of healthcare spend.
- Social Security designed for 60-year lifespan; people now live 20 years longer.
One year of lifespan gain ≈ 4–5% of annual GDP.
- Slowing aging by 10 years = $367T in U.S. economic value.
Peak-earning 50–65 cohort staying healthy = massive wealth accumulation.
- Fewer dependency years → reduced deficit pressure.
U.S. fertility hit historic low in 2024; longevity tech can fix the timing mismatch.
- Stem cell-derived eggs, extended ovarian function under development.
Longevity frames aging as a solvable engineering problem, not fate.
- Target: healthy lifespan to 160 years.
Required: NIH/FDA/ARPA-H investment, private capital, regulatory adaptation.
