Query: Would have been a lot harder without this book

A year ago my father became gravely ill and I have been working all this time to get him back to independent living. It has been a struggle and believe me, without The Complete Eldercare Planner I'd have never made it. With all my research and knowledge about caregiving to date, I can't help but wonder what people do that aren't knowledgeable.
