Biological aging is driven by the interaction between accumulated cellular damage and the decline of homeostatic resilience mechanisms, rather than chronological time alone.
Focus on maintaining healthspan by understanding that aging is not just a clock ticking but a biological process influenced by damage and repair. While no specific protocol is given, the implication is that interventions targeting the hallmarks of aging (like inflammation, mitochondrial function, or senescence) may slow biological aging.
GoodSupportsHIGH confidence
We postulate that the interaction between damage and repair could explain why some individuals are aging 'faster' and studying them jointly may point to the mechanisms of accelerated aging.
Why this rating
High-quality review of multiple human observational studies and animal models, though direct causal interventions in humans are limited.
