The way I understand it, the average life expectancy today is around 75 or so. But as I've read a variety of history books and articles, many of the older authors, founding fathers, et al have passed on when they were well into their 70's, 80's, or older. If we were able to kick out of the statistic all those that died under the age of say, 10 years old, between the years of 1700 to present, we the average life expectancy be any different than it is today? We have made great strides in infant death and mortality, as it wasn't at all unusual for kids under the age of 5 to die from a wide range of maladies way back in the day. But do we really live that much longer today than we did way back when?
