Tribal nomads of 100000 did not live to their 60’s.
AFAIK they rarely lived beyond 30.

Other research reveals that the lifespan of Homo sapiens may have changed from the Middle Paleolithic to the later Upper Paleolithic, since the ratio of older to younger remains increases. The same research shows that starting about 30,000 years ago at the beginning of the Upper Paleolithic, the average lifespan began to push past 30 years.

Note that Lifespan is not the same as life expectancy:

Lifespan is the maximum length of time that a person can live

So 30000 years ago 30 years was pretty much the maximum age a person could achieve.
