Age

Age is a term with multiple meanings such as 1) the time (duration, era) of something, e.g. space age. 2) duration phases such as maturing, declining, growing. "‘Age’ has in an older type the meaning of lifespan and maturity, the addition of feebleness or senility comes 2 centuries later.""In 2015, advances in DL and aging biomarker development began to converge. AI researchers at Insilico Medicine recognized that DL requires very large datasets, and that the most ubiquitous feature among varied and incompatible biological datasets is age. Age is a universal feature of every living organism and object on the planet. It is also the most biologically relevant feature because it is most strongly correlated with mortality, a broad range of diseases, and remaining quality-adjusted life years (QALYs). Although it can be difficult to correlate any individual feature with age, the combination of many features can be very predictive. A human can guess with reasonable accuracy the age of another human using low- and high-resolution imaging data, movement patterns, or even scent and touch." [Alex Zhavoronkov, Polina Mamoshina.
