    Aside from extremely strong priors about life extension effects (typically much smaller) and the ⁠low quality of animal research, some of the specific problems with the original result included:

    • contradictory median/lifespan figures

    • duplicate image

    • small sample

    • doses of C60 small enough that the direct antioxidant activity can’t be responsible

    • bizarre intervention, whose justifying cites were not published when experiment started

    • the C60 was administered for brief period (‘imagine taking a supplement only during your 40s and doubling your lifespan’)

    • the massive life extension observed in the olive-oil-only rats—not doubling, but still implausible
