That as people age, accumulate more and more private experiences, their sense of history tightens, narrows, becomes more personal? So that to the extent that they remember events of social importance, they remember only for example 'where they were' when such-and-such occurred. Et cetera et cetera. Objective events and data become naturally more and more subjectively colored.
