Life expectancy numbers are easy to fudge. Everything depends on what you include and which deaths you exclude. It bothers me that we claim longer average life than in the the past but we leave out the deaths at early ages that seriously lower our current average life spans. We have an awful lot of people who die the day they are born and they are not included in the calculation. Include babies who die the same day they leave the womb and the numbers will not look so hot for modern Americans.
