[ QUOTE ]
also remember that a human life span was prob around 30 years before modern medicine. im pretty sure i wouldn't have time to be depressed if i had to grow up, have kids and take care of them until adulthood in a truncated timeline. we are "wired" to be dead before this becomes an issue. [/ QUOTE ] That is not the case. The increase in life expectancy is primarily due to reduction in infant and child mortality, not expanding the life span of adults. A 15-year old in the Upper Paleolithic Era is estimated to have had a life expectancy of 54. http://en.wikipedia.org/wiki/Average_life_span |
