A dose-response survival advantage was found for book reading by tertile, after adjusting for relevant covariates including age, sex, race, education, comorbidities, self-rated health, wealth, marital status, and depression.
Book readers live an average of two years longer
Book reading contributed to a survival advantage that was significantly greater than that observed for reading newspapers or magazines. Compared to non-book readers, book readers had a 23-month survival advantage at the point of 80% survival in the unadjusted model. A survival advantage persisted after adjustment for all covariates, indicating book readers experienced a 20% reduction in risk of mortality over the 12 years of follow up compared to non-book readers. Cognition mediated the book reading-survival advantage (p = 0.04). These findings suggest that the benefits of reading books include a longer life in which to read them.
Not quite this saying about 1000 lives but maybe 1.03 lives
