Anyone can start here · Clinic/community centre with calibrated dynamometer, São Paulo, BR

Handgrip dynamometry + percentile — São Paulo (international tile).

Fund it for $180. Proof lands onchain when it's done.

$180 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

What the work involves

Grip strength predicts mortality across diverse populations (PURE/Leong spanned low-, middle-, and high-income countries). A calibrated dynamometer plus the right normative table makes the strongest cheap strength proxy work in any place-type.

Three efforts per hand in the standardized posture + best value per hand (kg) + age/sex percentile (population-appropriate table) + dynamometer readout photo

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

  • calibrated hand dynamometer (Jamar or equivalent)
  • standard chair
  • recording sheet

Steps

  1. 1. Seat the person, shoulder adducted, elbow flexed 90 degrees, forearm and wrist neutral (Southampton posture).
  2. 2. Set the dynamometer grip to the person's hand size; demonstrate a maximal squeeze.
  3. 3. Record 3 maximal efforts per hand, alternating hands, with ~15 s rest between efforts.
  4. 4. Take the highest of the three per hand (kg).
  5. 5. Compare the best value to the age/sex percentile table; record percentile.
  6. 6. Photograph the dynamometer readout; log both hands, best values, percentile, and posture confirmation; sign it.

What counts as done

  • Three maximal efforts per hand in the Southampton seated posture
  • Best value per hand in kg with the age/sex percentile (population-appropriate norms)
  • Photo of the calibrated dynamometer readout

Proof is measured against these, not judged by taste.

The money and the proof

What is promised, and what is not.

Funding this work is a purchase or a vote, same act: you either want this done here, or you want the world to contain it. A vote is free and signed; funding starts at one cent and anything beyond the wage is recorded as a premium for the worker. Either way the money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788107282059_89ef43f","funderWallet":"0xYOU"}.

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.
