The race between medicine and the clock
The trace is one number over time: years of healthy life returned per year of research. Below 1.0, the clock still wins; the day it crosses 1.0, life expectancy rises faster than time passes — longevity escape velocity. Solid = measured / reported, dashed = speculative. Click any wave to open it.
The same waves, read as a relay
Each advance handed the next a new capability — and exposed the next limit. Read top-to-bottom, the field is a baton pass from measuring aging, to slowing it, to reversing it.
What we actually know, by confidence
The field mixes hard results, reasonable inference, and venture-funded hope. Each claim gets a verdict, a confidence bar, and the one-line reason — and the honest counterargument.
Not one prediction — a fan of outcomes
Whether the curve crosses 1.0 in a decade, never, or only for some, depends on assumptions no one can yet pin down. Four ways the next thirty years could run.
How every cause of death defeats itself
Aging research runs the same loop on each failure mode — and the loop never ends, because removing one cause of death simply promotes the next. This is the engine, and the catch, beneath the whole field.
