Writings


  1. 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
