Well, that isn't inherently obvious, it only applies if your current
day personality is constantly being formed by reference to past
memories, rather than the memories making an impact when they happen,
and perhaps as they are processed in sleep, but having no long term
effect beyond this impact on the structure of the centers of reasoning
as they are processed.
