I wish EVERYBODY knew this simple fact. I have often debated with people about various issues, when they bring up the "average life expectancy was 40"(or some other low number). I've had this happen here on FreeRepublic even.
A properly functioning human body is probably good for 80-90 years. Take away infant mortality, and the median life expectancy has probably not changed all that much.
We DO have better medicines and what not, but then again, our lifestyles as of late are making us die even sooner than we should, if we didn't have such poor lifestyle habits.
Maximum likely quantity has not changed, but quality certainly has. From hip replacements to painkillers to arthritis drugs, most elderly today are far more comfortable (and that's not even including air conditioning) than their elderly ancestors.
