The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

you can get tests now there are plenty of companies now that are selling these things where you can go buy your epigenetic blood test mostly this has been done in blood cells that's one limitation to think about is almost all of the literature in humans is developed on epigenetic clocks from blood and it's it's still i think a little bit of a question you know what if even if this is reflecting biological age it's the biological age of your blood which may or may not reflect the biological age of your entire body

and it's also an interesting time because we're starting to see commercialization of these you know so-called aging clocks that are being sold to the general public um and again you know I think you can have a debate about what the evidence is that these things are actually measuring biological aging are they doing it accurately
