This document discusses how ageing and design can contradict each other but that with persistence and adapting to user needs over many years, useful products for an ageing population can be successful. It provides examples of both successful long-lasting products like Good Night Lamp that address family connection needs over a decade as well as design fiction projects that failed to be implemented. The author advocates for continuous user research and seeing design as an ongoing sales process to meet changing user needs rather than a one-off problem solving exercise.
