Peakspan measures each function against its own peak, not one whole-person peak
This Perspective defines Peakspan as the age interval during which a person maintains at least 90% of peak functional performance in a specified physiological or cognitive domain. The definition is system-specific: a person can remain near peak in one function while having moved below the threshold in another.
Research basis
Perspective and multi-system synthesis. Published research across cognitive and physiological domains.
What it supports
Domain-specific functional peaks and asynchronous trajectories across the working life.
Boundary
The paper introduces a definition and synthesizes existing literature. It does not validate the 90% threshold as clinically or occupationally meaningful, establish a universal Peakspan instrument, or demonstrate that maintaining a measured function improves productivity or leadership performance.

The lead author is affiliated with Insilico Medicine, a commercial AI drug-discovery and aging-research company.
Any age intervals reproduced from the Perspective must be labeled as the authors’ secondary synthesis and checked against the cited primary studies. The audit’s allegation of a Peakspan-named commercial venture was not substantiated and must not be repeated.
