Lots of interesting tidbits of information in the book from the author and people that wrote to her newsletter. Not all information will apply to everyone and some is outdated but there is enough basic info that I found useful to at least try the suggestions. Also some recipes for various things. Since the book is over 900 pages, not available in all libraries, and takes a long time to get through I wanted my own copy to use as a reference . I had read the book before - borrowed from the library - but found it on Amazon at a good price for me.
