Scientists generally agree that biological age, distinct from chronological age, is a measurable reality that can predict disease risk. Tests like GrimAge and iAge, which analyze DNA methylation and chronic inflammation respectively, have shown correlations with cognitive decline and heart disease vulnerability.
