Haven’t dug into the data but from reading this article it seems like having untreated diseases/poor health in general increases the risk of dementia rather than these classes of drugs directly reduce risk.

I’d also suggest that being vaccinated and being prescribed these medications is correlated with being in regular contact with the healthcare system which may be the more relevant factor.

It made me laugh, it’s not silly per se but the idea that such an esteemed title as blue zone was earned through pension fraud is hilarious.

The more schadenfreude version is that the idea of these blue zones has been trotted out ad nauseum by longevity nuts for at least a decade and now they look like fools.
