Well a healthy heart is a good basis for 'longevity'. "Wild", not-primarily/fulltime-agricultural and
fully nourished tribes are also throughout the ages known to have never encountered diabetes alzheimers dementia bone-issues tooth-decay gout etc. How the heck do you account for the relative/potential/likely lack of vaccines/antibiotics/ambulances however? For at least a half million years, the life-span of
any human individual that survived birth and somehow avoided/survived all the sorts of infections (that
we are not
inherently immune to either, absent pharma)
and accidents and strife inherent in their lifestyles long enough was entirely within range with what modern homo sapiens can hope for,
with medicines/ambulances/care-homes etc. It's just that on the whole, many-probably-most didn't make it that far to begin with. Those who managed to, were of course treasured respected and prompted for their 'wisdom' =)
A large part of "the strides medical progress has achieved" in terms of longevity is entirely about dealing with "the diseases of civilization" that we invented in the first place (out of necessity and lacking better info) with a chronic highish intake non-stone-age food-stuffs, cities, heavy industries etc.
