: If caloric restriction in mamals works be changing cellular activity into a survive and protect mode, potentially increasing lifespans, why didn’t our prehistoric ancestors with low caloric budgets not live long?
In: Biology
They had other issues shortening their lifespans like disease and injury. If they didn’t die from something like that, they could actually live a lot longer than we think of when we think of stereotypical cavemen. But there were a lot more dangers and a lot fewer safety nets and cellular efficiency doesn’t help with those things
