PositiveThe Los Angeles Review of BooksWhile an impressive display of erudition, Natural Causes brings something far rarer to the discussion of aging in print: a sense of humor. Ehrenreich is a very funny companion on the aging \'journey,\' especially when sharing her own experiences and conflicts ... Her personal story also helps ground some of the sharpest critiques, such as the profit motive in medicine driving treatments that may actually harm more than help ... This light touch is not uniform throughout, and some of the book’s arguments are weakened by what feels like gratuitous snark, a knowing tone gone snooty that can distance the reader, cropping up in parts not leavened by her own experience. Still, even with these intrusions, and despite her own stated intention to offer no guidance, Natural Causes provides insight and solace.
