The most important fact justifying aging/longevity drug discovery is that *lifespan-extending drugs exist.* Lots of them. If you screen 1280 well-known drugs and natural products on nematode worms, 5% of them significantly extend lifespan. https://onlinelibrary.wiley.com/doi/pdf/10.1111/acel.12163 …

Worms are very different from people, of course. But 7% of the drugs in the DrugAge database that were reported to extend life in worms were also tested in mice and found to extend life in mice.

Didn’t the “fasting mice live longer” thing get debunked? I am much more wary of mice results now Incidentally I’d be interested in reading a blog post breaking down what median longevity increases historically can be attributed to

https://onlinelibrary.wiley.com/doi/full/10.1111/j.1474-9726.2006.00236.x … It doesn’t work in wild mice, or in thermoneutrally housed mice. For lab mice in standard conditions, dietary restriction does extend life.

Plus, not all things that extend life in mice are pure DR mimetics; we know rapamycin isn’t, for instance, and I suspect some of the other big-effect-size stuff isn’t either. (Spermidine, NAC, selegiline, all very different proposed mechanisms.)

You’re going way over my head now so I’ll take your word for it
