When the record changed
- Earliest reviewable baselineU.S. National Institute on Aging anchors the first layer used on this page.

- SALGIL editorial reviewOriginal, interpretation and outcome are retained as separate records.
06 · EDITION AND WITNESS COMPARISON
How the evidence for Longevity and the Biology of Aging changes
The date of a document and the date of an interpretation are recorded separately.| Witness or edition | Date | Editorial status | Why it matters |
|---|---|---|---|
| U.S. National Institute on Aging | 21st century | Baseline source | Animal results, biomarkers, clinical outcomes and commercial longevity claims must be separated. |
| Scholarly or institutional interpretation | Later review | Context layer | Explains language, history and uncertainty without becoming the original text. |
| Viral quotation or modern event match | Recent circulation | Derivative layer | Most vulnerable to translation drift, omitted failures and hindsight; compare with U.S. National Institute on Aging. |
07 · MAJOR CLAIMS
Representative claims and their limits
Central claim
Targeting aging biology may delay multiple age-related diseases.
Original-first test
The claim is checked against U.S. National Institute on Aging, not against a later summary.
Outcome test
No intervention has established extreme human lifespan extension; healthspan evidence remains intervention-specific.
08 · WHAT ACTUALLY HAPPENED
Comparison with events
No intervention has established extreme human lifespan extension; healthspan evidence remains intervention-specific.09 · DISPUTES AND COUNTERARGUMENTS
Where interpretation changes
The main dispute concerns the distance between 21st century and Basic mechanism · clinical trial · commercial extrapolation. Translation, selective quotation, changed definitions and hindsight can make a broad record appear more exact than it was. Competing readings are therefore preserved rather than silently merged.10 · EVIDENCE SCORE & PROVISIONAL CONCLUSION
Research active · claims uncertain
Geroscience studies mechanisms of aging and interventions that may extend healthy life. SALGIL's provisional score reflects source traceability and testability, not religious worth or cultural importance.11 · SOURCES AND REVIEW
