The Neutralization Destiny Equation—Maintenance Boundaries of the Carbon-Based Power Grid and the Physical Foundation of Longevity

Why do all carbon-based multicellular organisms age irreversibly? This paper identifies a missing variable in aging research: the residual capacity of the repair system itself, E(t). The heart embodies E—a dissipation center so robust that cell division is physically blocked. The brain embodies M—low-resistance pathways maintained passively during sleep. From the monotonic decline of circulatory and neural function, this paper derives the Neutralization Destiny Equation, E(T) + M(T) = 1, proving the mathematical necessity of death. All twelve hallmarks of aging are uniformly explained as prioritized abandonment patterns under energy budget insufficiency. Six independent public-data analyses covering over 800,000 cases support the deductions. The heart guarantees the lower bound; the brain pioneers the upper bound. Longevity lies in not interfering with the automatic operation of these two systems.
