Bryan Johnson was recently diagnosed with autoimmune gastritis, an incurable disease. He claims he will attempt to develop a cure.

This resolves to yes if all of the following are true:

• Johnson claims to have been cured by a specific therapy or set of therapies

• Johnson is the first person known to have been cured of AIG by that therapy or therapies

• Someone else (not affiliated with Johnson) is also cured by the same therapy or therapies, as confirmed by a reliable source such as a scientific journal or hospital

  • If the therapy is personalized (e.g. tailored to the patient's genome), then a someone else being cured by a personalized therapy developed by the same approach counts

• Update 2026-07-07 (PST) (AI summary of creator comment): Regarding the "someone else is also cured" criterion:

  • The other person must be actually cured (not just improved/reduced symptoms)

  • The other person should be not affiliated with Johnson

  • A reputable source must confirm their cure

For Johnson himself, the creator will give him the benefit of the doubt on his own cure claim, given he funds his own doctors.
