Firstly, I would think they did NOT live to age 91 or even close.
I can't explain what you are referring to; I'm not an anthropologist, however, my daughter and her husband were anthropology /education majors in college......I'll check with them when I see them.
Here is what I just found.......for now:
Various ages of life expectancy throughout the times..........see below...
The median life expectancy has been estimated at ~35 years of age. This is about the life expectancy of the African Bushmen (Sans) of today. Due to their active lifestyle they suffered far more injuries that today's humans & wound infections would have killed many of them. Early mortality rates are also high among hunter gatherers as any genetic disease like diabetes was untreatable & fatal.
We don't know that there isn't a causal relationship between the gradually lengthening human lifespans since the dawn of agriculture and a grains-based diet, but we do know that all but tropical humans were forced to eat a high fat & high meat diet during winter months.
The Sans have had limited contact with the outside World & until very recently they lived as humans had in paleolithic times.
