What Your Handshake Reveals About Healthspan

Grip strength keeps showing up next to mortality and cardiovascular outcomes in large observational datasets — associated with, not destiny. In this episode we unpack what a handshake-sized measurement is actually proxying (muscle function, neuromuscular reserve, frailty clusters), how to stack evidence without mixing shelves (PURE / meta-analyses / EWGSOP2 clinic screens / animal data), and why optimizing a dynamometer score in isolation is not a licensed longevity lever. Soft claims only. No training prescriptions. No “train the hand to buy years.” Chapters (approx): 0:00 Cold open — the meter 1:30 What grip proxies 3:30 Evidence layers A–D 6:30 The predictor≠lever trap 8:30 Careful takeaways + CTA Sources discussed: PURE (Lancet 2015), Wu et al.
