One of the core arguments in this debate is that, regardless of increasing life expectancy rates, humans have an upper limit. This is probably best categorized as the Hayflick limit argument . That there is a maximum number of years that a human can live and if nothing gets to you before reaching that threshhold, when you do, that’s it – it’s over. That limit is about 120 years of age, with the oldest documented lifespan being the 122 attained by Jean Calumet

He cites the vast reduction in the infant mortality rate as being of particular note. But that is more reflective of initial gains and merely part of a larger trend at work. (cont.)
