When talking about average life expectancy, I was including pre-agricultural
mankind when as many as 50% of children died in the first year of their
lives. An average takes in all of the children born and not just those who
made it past the first year of life.
I was just reading a book by Johnathan Spence in which the Emperor of China
laments the fact that "the emperor's own family line seems somehow marked
for doom; of the nine sons and four daughters born to him by various
consorts up to the end of 1728, all the girls and six of the boys have died
from illness." "He has been convinced for years that people want to kill
him, and he has ordered the killing of many in return, including three of
his own brothers."
And this was a family with access to the best doctors in the country at the
time. So even though many people lived into their fifties and sixties, the
normal rigors of life took a great many more from wars, disease, family
squables, accidents, etc.
I agree that copying the survivors was a valid and useful strategy in
centuries past. The rise of technology has made rapid changes in our lives
and longevity and a thousand years ago it was centuries and milliniums
between paradigm changing advances. I'm sure this has a great deal to do
with the staying power of religious memes. In fact, it has a great deal to
do with be conflict between cultures. Books about philosophy hark back at
least 2,500 years in both Europe/America and China/Korea/Japan. Even in
post-communist China Confucius is making a comeback after having been banned
during the Cultural Revolution.
