I dunno, I think it's pretty trivial to back into life expectancy and genetic risk factors from publicly available ancestry information combined with death certificates. We have ~200 years of pretty good records here in the US and many more if you go into Europe's records. From that data you can get a really good idea of longevity for a given person.

Ancestry.com even has a public tool for doing this at a high level: https://www.ancestry.com/name-origin?surname=trujillo

Seems the cats been out of the bag for a long time.

Maybe you shouldn't throw around 'dumb' quite so liberally.
