Higher Predicted Age by a Metabolomic Aging Clock Correlates with Dementia Risk (opens in new tab)

Given access to a large body of biological data from people of various ages, creating an aging clock from that data is fairly straightforward and costs relatively little in time and funding. Thus clocks are proliferating, a new one published by an academic research group every few months. Most will vanish into obscurity. The problem is not the lack of a perfect clock for any given situation, but the lack of understanding as to how any given clock will react to a novel potential approach to sl...
