Who can volunteer for themselves
Movement 4 · The Flesh — September 2026
I The Perth calculation
In June 1984 Barry Marshall drank a broth containing a billion bacteria to prove that ulcers were infectious. Three days later he was vomiting. On the tenth day an endoscopy showed the gastritis. He cured himself with antibiotics and in 2005 he shared the Nobel [with Robin Warren].
The part that almost never gets told is the part that matters here: Marshall knew the rescue treatment, he had it in the cupboard [a metre from the bench] and he could give it to himself.
The self-experiment was reasonable because the damage was reversible in his own hand.
II Reversibility, which is the only variable
| Intervention | Can it be undone? | Who can stop it |
|---|---|---|
| Treatable infection | yes, with an antibiotic | the subject himself |
| Short-lived drug | yes, by waiting | the doctor |
| Cell therapy | partly | the clinical team |
| Somatic edit | no | nobody |
| Germline edit | no, and it is inherited | nobody, ever |
Each row down moves the decision further from the body that bears it. In the last one, the subject taking the risk has not been born. That is not a nuance. It is a different thing.
“A researcher's courage is only courage while the damage is his own and can be undone.”
III What replaced the glass
The legitimate way to go faster is no longer to drink anything. It is to cut administrative time without cutting oversight: adaptive protocols, platforms shared across several trials, and committees working alongside the design [not at the end of it].
The baby treated in 2025 with an edit designed for his mutation worked that way — six months from diagnosis to dose — and not through anybody's heroism.
IV How to read a consent form [safe]
- Time yourself. Fourteen pages take about twenty minutes and almost nobody spends them.
- Find what happens to leftover samples and whether there is compensation.
- Find who pays if something goes wrong, and for how long.
- Find the follow-up plan: how many years and who funds it.
- Ask which part of what you are signing is irreversible. That is the only sentence you really have to understand.
V Risks
Demanding absolute reversibility would freeze half of medicine. A prosthesis cannot be undone either and nobody argues about it. The useful criterion is not to ban the irreversible; it is to separate clearly what can be stopped from what cannot, and to ask for oversight proportional to that difference.
The opposite risk has already been seen. Where regulation is weak, clinics appear selling the irreversible as if it were cosmetic; they charge up front. That exists already. It has brochures.
VI Coda
Marshall could volunteer for himself because the antidote was a metre away.
Almost none of the therapies we are discussing now have an antidote; which is why honest acceleration in this branch runs through committees and not through anybody's stomach.
