Do you suspect a higher percentage of those of the Tsimane who died young would have developed dementia after 65 (which seems to be the cutoff they're using)? That would be an interesting result, but unless there's some reason to think it, it's just one of many potential hypotheses.
- tptacek 3y agoI don't know! I think the subtext of the article is that the Tsimané have, ceteris paribus, a lower incidence of dementia --- that if you could keep the lifestyle and environment constant and raise the at-birth life expectance of these people to modern standards, they'd still have low rates of dementia. I'm wondering if that's true, and how you'd go about investigating that.
