Even if she lived to 150, a skeptic would just say it's a fluke and we have to wait 110 years for a large cohort double blind placebo controlled multi-center study of 40 year olds to finish at $800,000 a procedure before we can say that the intervention worked. It wouldn't get past the IRB either.

Longevity science, even if it works, will be impossible to prove to skeptics for purely practical reasons.
