Deep DiveStrength as a measurable variable: assessing and building capacity that lastsHow to read the cheap measurements that track independence, grip, gait speed, the five-times sit-to-stand and the short physical performance battery: how each is taken, why the published cut-points disagree, why power fails before strength, what genuinely governs adaptation at any age, and where protein and supplements honestly stand.Deep DiveBuilding a panel worth repeating: markers, intervals, and reading a trajectoryHow a small longevity panel is actually built: what each marker adds that the others do not, what stays off it and why, how the interval for each is set, what makes two years' values comparable, and how to tell a real trajectory from one unusual day.
