I immediately wonder how this affected the EOL conditions of those mice.

Article states they had fewer biomarkers of aging, and showed less age-associated obesity, fraility, and metabolic decline. So their "youth" period extended longer.

Actually the point of healthspan vs lifespan is made in the introduction -- it was a justification for using mice for this study, which have clear health phenotypes that are analogous to humans.

I'm basically skeptical of any longevity study in mice or yeast or C. Elegans because I think humans already have superior longevity factors over other animals because of our culture: we can live 3x reproductive age and still contribute to the survival of our descendants and our tribe.

Metabolic adaptations that prolong the life of mice might be just bringing them closer to where we are as opposed to something that would work for us.

They outlived their retirement savings and had to re-enter the workforce. It's just a rat race, isn't it.

Not to mention the radical cost of living adjustment, renting some hole in the wall just to squeak by.
