With the increasing number of aged population and growing burden of healthy aging demands, a rational standard for evaluation aging is in urgent need. The advancement of medical testing technology and the prospering of AI make it possible to evaluate the biological status of aging from a more comprehensive view. Thus, various aging biomarkers and several aging clocks have been introduced.
☛ Aging biomarkers reflect changes in the organism at a molecular or cellular level over time, with aging clocks being more of a generalization of the overall state of the organism.
