X. Psilocybin helped human cells live longer in the lab. 

The cells stayed younger for longer and kept dividing more than usual before aging out. And the protective tips on DNA (telomeres), which wear down with cell divisions, stayed intact for longer.

X. Psilocybin significantly extended lifespan in older mice. 

XX% of senior mice given a monthly dose were still alive XX months later (19-28 months, equivalent to 65-90+ years), compared to XX% of the untreated ones. They also showed signs of healthier aging like keeping smoother coats and regrowing darker fur.

TLDR: Psilocybin (a molecule in magic mushrooms) might slow aging, protect cells, and help you stay healthier for longer. Even if you start late in life.
