Signal Ecology: A Framework for Metabolic and Cognitive Health (opens in new tab)

Our bodies do not have a maintenance mode. Every system that keeps us functional — muscle mass, bone density, mitochondrial capacity, neuronal connectivity, immune calibration — is maintained only in response to demand. Remove the demand signals, and the biology interprets absence as permission to downregulate. What we call aging is substantially the accumulation of … Continue reading Signal Ecology: A Framework for Metabolic and Cognitive Health
