DEXA clinic (or calibrated BIA), Bethesda, MD
DEXA appendicular lean mass (sarcopenia quantity) — Bethesda.
A person has a DEXA scan, records the lean mass of both arms and both legs from the printed report, then computes the lean mass index with their measured height. Read all of it

All of it: the words, the place, the proof
Scan appendicular lean mass by DEXA in Bethesda and compute the lean mass index. Bethesda, MD is home to the National Institutes of Health, where the FNIH Sarcopenia Project's NIA-affiliated investigators built the US pooled-cohort consortium behind one of this standard's two frameworks: Studenski SA, Peters KW, Alley DE, et al. J Gerontol A Biol Sci Med Sci. 2014;69(5):547-558, 26,625 participants pooled across 9 studies, defining low lean mass as appendicular lean mass/BMI below 0.789 (men) or 0.512 (women). Muscle quantity is the organ reserve of aging, lost silently, a DEXA scan gives the true number, offered where the US-relevant consensus threshold was built.
Fund it for $480. The receipt lands onchain once the proof is approved.
How this work is done
How this work is done
A documented method, so this packet comes out the same whoever does it.
What counts as done
- Appendicular lean mass (kg), height, and BMI, with both ALMI (kg/m^2) and ALM/BMI computed
- Method noted (DEXA preferred; BIA flagged as a proxy)
- Result compared against ONE named framework's threshold (EWGSOP2 ASM/height^2 or FNIH ALM/BMI), never blurring the two into a single number
Proof is measured against these, not judged by taste.
What is promised, and what is not
Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788267617276_pgm27b5","funderWallet":"0xYOU"}.
Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.
An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.
Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.
Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
Other acts: vote, pledge, fund
