Across the arc of a human life, few habits prove as quietly powerful as the act of reading. Researchers at Cambridge have confirmed what many readers have long sensed: engaging with text for pleasure — in any form, at any age — measurably strengthens memory, deepens empathy, and supports mental health. The finding is notable not only for its breadth but for its democratic implication: no special genre, no particular format, no expert guidance required. The book, in whatever shape it takes, may be among the most accessible instruments of human flourishing we have ever had.
