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.
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.
A man vows, and yet will not east away the means of breaking his vow. Is it that he distinctly means to break it? Not at all; but the desires which tend to break it are at work in him dimly, and make their way into his imagination, and relax his muscles in the very moments when he is telling himself over again the reasons for his vow.
