Based on the "field notes" she keeps in her journal, Memory's Last Breath is Saunders' astonishing window into a life distorted by dementia. She writes about shopping trips cut short by unintentional shoplifting, car journeys derailed when she loses her bearings, and the embarrassment of forgetting what she has just said to a room of colleagues. Coping with the complications of losing short-term memory, Saunders nonetheless embarks on a personal investigation of the brain and its mysteries, examining science and literature, and immersing herself in vivid memories of her childhood in South Africa.
