input with options: Title: Staggering neurobiographical study Review: Engrossing, moving, well-documented, supplemented with enlightening footnotes. Sacks documents an almost-forgotten plague and its few pitiful survivors. He explores a theme that he has returned to in subsequent books (especially in his latest, "An Anthropologist on Mars"), humanity preserved in the face of dehumanizing disease. It also presents humans helping humans live in the here and now, not just preparing for the Hereafter that may or may not await. Is this product review negative?
output: No
