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.

Humans by Era Average Lifespan at Birth
(years) Comment
Upper Paleolithic 33 At age 15: 39 (to age 54)
Neolithic 20
Bronze Age and Iron Age 35+
Classical Greece 28
Classical Rome 28
Pre-Columbian North America 25-30
Medieval Islamic Caliphate 35+
Medieval Britain 30
Early Modern Britain 40+
Early 20th Century 30-45
Current world average 67.2 2010 est |
I think milk or nutrition aside
most of these average life expectancies would be many years higher if they had the improvement most of the current world enjoys with newborn survival rates.
