There is still no global consensus on when natural aging ends and disease begins. If I feel 60 but my biomarkers say I am 40, am I sick or just an outlier? Why hasn’t 2026 science fixed the classification of aging as a disease yet?
There’s no global consensus because aging is universal, gradual, and deeply variable — unlike traditional diseases, which are defined as abnormal deviations from the norm. Modern science clearly shows that aging is driven by measurable biological processes (like cellular senescence and epigenetic changes), but since everyone experiences them to some degree, regulators struggle to label it a “disease.” If you feel 60 but your biomarkers read 40, you’re not sick — you’re simply biologically younger than average. The challenge in 2026 isn’t lack of science; it’s that medicine, policy, and philosophy haven’t agreed on when natural variation crosses into pathology.
