"decelerates aging clock" implies slowing down processes of decreasing health, not just living longer in a frail state at the end. In particular if you click the link, the first thing it says is: • Metformin prevents brain atrophy, elevating cognitive function in aged male primates • Metformin slows the pace of aging across diverse male primate tissues • Metformin counterparts neuronal aging, delivering geroprotection via Nrf2 in male primates It doesn't even say you'd live longer. If I could get something that doesn't extend my life at all, just keeps my brain fresher into my old age, I would jump on that as well.
