Basically, a medical guide to physiological changes in aging--where a health guide been more beneficial. Pizer (Coping with a Miscarriage, Guide to the New Medicine) Ires started out, aptly, by gathering together pieces on general life changes, coping with age and loss, protection against consumer frauds, and body maintenance (exercise and nutrition) which are made personal by incorporating individual experiences. This worthwhile introduction never goes far enough, however: nutrition and exercise advice is much too brief (little attention is paid, for instance, to the specific nutritional needs of older people), and scant consideration is given to continuing development and enrichment (the focus, indeed, often seems to be on loss and dwindling). The bulk of the book is then devoted to describing medical problems: first, how to deal with doctors and the health-care system (helpful, but again too general and too brief); next, what to expect system-by-system as the body ages. On first aid, there are useful pointers; on drugs and medication, the text erratically points out drug-drug interactions and ignores other problems special to the elderly (most prominently, over-medication). Nothing better is on hand at the moment--but this is far from complete as a source of information (and out-of-the-running as regards prevention and healthful living).
