Our time is managed; it is not our own. Psychologists Ryan, Hatfield, and Hofstetter (2002) report that while 75% of adults over the age of 65 consider themselves morning people, only 10% of those under age 65 feel that they can be categorized in this way. These subjective ratings for peak productivity times also correspond with data from objective measures of cognitive functions, including analytical thought and judgment, memory, and the ability to suppress irrelevant information (e.g., wandering thoughts) (68).
