The cardiac cycle occurs once every second so, like our own lives, we won't be able to remember every memory or every heartbeat.  Just the loud loud ones.  Just the calming ones.  The stories within the story should be considered as phases or snapshots caught in time whose series, when connected on paper, can serve as the parts to a larger story.
