Nobody knows.  Also, "average" age isn't a very useful measure of
health, because it includes child mortality, accidental deaths, 
warfare, etc.

Much more useful is life expectancy at a given age.  Ideally we
would know the life expectance at age 0, 1, 10, 20, 30, 40, etc., 
for any given population.  In terms of health and quality of life
life expectancy at 50 is far more interesting than life expectancy
at age 0.

Unfortunately we don't even have that data for a lot of people
living today, certainly not contemporary hunter gatherer societies,
never mind paleolithic peoples.
