This market will resolve to the first year when the average-looking 40-60 year old person can use technology (medical, cosmetic, etc.) to look (almost) indistinguishable from an attractive 20-year-old person.

The technology does not have to be affordable, it only has to exist. If, for example, Bryan Johnson successfully uses his millions to look very young (when judged by a neutral observer, and in person), and documents it thoroughly, this market will most likely resolve YES.

The market will NOT resolve based on digital alterations, temporary cosmetic effects, or single anecdotal cases without verification.

• Update 2025-05-11 (PST) (AI summary of creator comment): The creator has clarified how a single well-documented case will be evaluated for market resolution:

  • A single such case serves as proof of concept.

  • For resolution, the case requires:

  • Expert verification.

  • Clear evidence that the results are not anomalous.

  • If significant doubt remains about a single case (even if verified and non-anomalous), resolution will await additional verified cases.
