My edition of this book is somewhat dated, but the information within it is truly informative. Some of the information hasn't changed much if at all since this edition was written (copyright is 1989, which perhaps shows how slowly medical progress is made). Many of the concerns addressed are still current concerns, and many of the things touched upon are unchanged since this edition was written.
I wonder if a new edition is out? If so, it might be interesting to see just how much has changed in terms of topics covered and advice given.
