The experiencing self lives in the moment; it is the one that answers the question, 'Does it hurt?' or 'What were you thinking about just now?' The remembering self is the one that answers questions about the overall evaluation of episodes or periods of one's life, such as a stay in the hospital or the years since one left college.

But people are mildly pleased most of the time, they're mildly tired a lot of the time, and they wish they were somewhere else a substantial part of the time - but mostly they're mildly pleased.
