The linked article is intentionally misleading by omission because they left out "in mice" in the university driven article and they certainly know the relevance and consequences of leaving it out.
Multi vitamin use has been studied A LOT with respect to all cause mortality, where it consistently has no statistical effect (or a slightly negative effect). So, to me, "biological aging" seems a way to hack for effects to advertise. Does the average consumer understand that reduced "biological aging" does NOT mean you will live longer? Because if it did, they would be saying THAT. Centrum (study sponsor) is already creating advertising based on this study.
Partially funded by entity related to manufacturer of daily multivitamins. Study was in people over 60 average age 70 if I recall. I didn't care enough to look, but the question I'd ask is how were the people who died during the study accounted for in the "biological aging testing?"
I have a colleague that recently self-published a book. I can easily tell which parts were LLM driven and which parts represent his own voice. Just like you can tell who's in the next stall in the bathroom at work after hearing just a grunt and a fart. And THAT is a sentence an LLM would not write.
That book used artwork valuation as a performance measure and analyzed it over top artist's lifetimes finding two patterns. The "Young Genius" where an artist has a vision and realizes some innovation and their most valuable works center around that with value tapering off over their life. Picasso. (Who had two peaks but still fit the pattern.) Contrast to the "Old Master." This is someone who keeps refining their craft and their most valuable works and innovations are their late life works. Cézanne.
