Comparing aging biomarkers across different longevity studies

This article talks about a big comparison of 51 different studies to see which aging biomarkers actually respond reliably. It looks at things like epigenetic clocks to figure out what we should really be tracking.
Not gonna lie, I find this kind of meta-analysis very useful. There is so much noise in this space right now. People post about their biological age every single day, but it feels like everyone is using different metrics. Some people swear by Horvath clocks, while others focus on different blood markers. It is hard to know what is actually a real signal and what is just random variation.
I think we need more of this clarity before we go overboard with expensive testing. If we cannot agree on which markers are the most stable, we are basically just guessing with our protocols. It makes me wonder if we are over-relying on epigenetic data too early. Do you guys think these clocks are actually useful for tracking small changes, or are they too blunt for daily monitoring? ⚡
