Quote by Andrew Tobias
Man's natural life span, 75 to 90 years or so, has not increased. It is the number of us who manage to attain it that has increased.
Summary
This quote suggests that the average length of human life has remained relatively unchanged, typically ranging from 75 to 90 years. However, what has changed is the increasing number of individuals who are able to reach this natural life span. In other words, advancements in healthcare, technology, and overall living conditions have enabled more people to live to old age, leading to an increase in the proportion of individuals who reach the typical life span rather than a lengthening of the life span itself.
