Chronological Time and Viability Time: Aging as Nonlinear Dynamics of Viability Architecture

Abstract

This article proposes investigating aging as nonlinear dynamics of system viability architecture relative to chronological time. The approach builds upon established research on the hallmarks of aging, biological age, Pace of Aging, frailty, comparative longevity, and negligible senescence without seeking to replace these concepts. The starting proposition is that duration of existence and degree of viability change are not equivalent quantities. The article distinguishes Chronological Aging from the working concept of Viability Aging, defined as accumulated change in viability architecture expressed through critical functions, recovery capacity, dynamics of future viability boundaries, resource transformation, and disturbance history. Comparative evidence from exceptionally long-lived organisms demonstrates that rates of age-related change differ substantially among biological architectures. The Greenland shark exhibits a lifespan of several centuries; the ocean quahog exceeds 500 years; and the naked mole-rat demonstrates an unusually weak age-related increase in mortality risk within the observed range [5–8]. These cases are not treated as evidence for Vitology, but as empirical grounds for testing the proposition that chronological time alone is insufficient to explain the rate of aging. The hypothesis of viability-architecture aging is formulated, together with conditions for its falsification.
