What is longevity?
Longevity is lifespan, the years you get. Healthspan is the share of those years you spend in good health, and the two part company for most people somewhere in their sixties. Everything a longevity clinic does aims at that gap.

What United States asks about longevity
Longevity is lifespan, the years you get. Healthspan is the share of those years you spend in good health, and the two part company for most people somewhere in their sixties. Everything a longevity clinic does aims at that gap.
Biological age is an estimate of how worn your body is, built from measurements rather than your date of birth. Someone who is fifty on paper can test at forty or at sixty. The number matters because it moves, and because you can move it.
Clinical tests read DNA methylation from a blood or saliva sample and score it against population data. Consumer calculators use blood pressure, resting heart rate, waist measurement and habits instead, and they are rougher. Whichever you use, keep using the same one, because comparing across methods tells you nothing.
