The term “senior moment” typically refers to an age-related lapse in memory, logical thinking, or sense of orientation. But appearing at a loss is merely a common trick to conceal actions that are part of a highly coordinated effort. Driven by deep-seated memories and using long-term spatial planning, the elderly have been conspiring to realize a surprising plan. Volume 29 uncovers this historical phase, as a “Senior Moment” of elderly triumph. The issue presents “the plan,” identifies the “locations,” “members,” and “assets,” and uncovers strategies involved in urbanism for aging populations. With Leon Krier, Michael Graves, Yoko Ono, Paola Antonelli, Aubrey the Grey, Lebbeus Woods, and more.
