A researcher discusses a September 2023 paper arguing that existing biological-age tests fail to distinguish sick from healthy people. Linear regression models used in current clocks don't have real clinical value, and measuring biological noise offers a better approach to assessing how fast you're actually aging.
So when was this discovered as a way of measuring aging, this biological noise? It was published on 2023 in September. And that was when we literally published that paper on the front cover of aging, saying that everyone else is not doing the right job because we basically failed test every single paper. And after that paper, there's another paper that we published on geoscience saying that this model, the linear regression model, which is we are referring to as a clock model, they cannot differentiate people who is having disease versus healthy. This is a very important point. If your biological age cannot tell you if you're sick or not sick, then what is the point of testing it?
