The Gompertz Law: Why Mortality Risk Doubles Every 8 Years
Ever wonder why health seems to drop off a cliff later in life? It's not just your imagination—it's math. In longevity science, we follow the Gompertz-Makeham Law of Mortality. This principle shows that after age 30, your risk of death doubles roughly every 8 to 9 years.
How the Curve Works
The chart on our homepage isn't just a random line. It represents your Hazard Function—the annual probability of mortality.
- Baseline: We set your starting risk (Alpha) using 2026 data from Statistics Canada and the UN.
- The Slope: The 'Rate of Aging' (Beta) determines how fast that risk accelerates.
- The Shift: When you improve your VO2 Max or sleep quality, you aren't just 'adding years'—you are actually lowering your hazard ratio and flattening that exponential curve.
Why This Calculator Is Different
Most tools use outdated point systems. The Longevity Engine uses a professional Proportional Hazards Model.
- No Email Walls: Your data stays in your browser.
- Compound Math: We multiply risks (like smoking + stress) rather than just adding them, which is how human biology actually works.
- 2026 Data: Grounded in the most recent actuarial tables available.
