I wasn't saying it couldn't attenuate faster; I was just saying it clearly attenuates. I think that clearly one could conceive of a hunter gatherer existence where the grandparents do provide help to grandchildren - I have vague recollection of something about a modern indigenous society where grandparents watch grandchildren while parents hunt and gather, but it's sufficiently vague that I'm not confident in asserting anything about its reliability beyond mention. Again, though, when discussing evolution we're talking about human-design-space, not specifics about individual human cultures.

Yes, in principle, and that is definitely a good point. But with hindsight we can observe that the part of the "design space" that includes 90 year olds was never before explored, and hence evolution tells us nothing about whether or not hunter-gatherer diets are good for longevity.
