Another sound, simple guide to better cardiovascular health--this time, from the host of the PBS-TV series ""Here's to Your Health."" Kaplan has done a nice job of rounding up the latest information on how smoking, hypertension, obesity, diabetes, physical activity, stress, alcohol, and sex relate to cardiovascular disease. For each, he presents the facts; sets out a plan for improvement (how to quit smoking, how to begin or upgrade an exorcise program, what to drink); and provides good, recent references to enable the reader to go further. In a larger frame of reference, he also notes that the individual can't do everything: ""A humane, sensible approach to the problem is for our institutions to provide the knowledge and direction for self-care, to remove as many harmful things in our environment as possible, and to support those services that only society, through our governments, can supply."" A well-organized, well-rounded alternative to some of the special-focus (exercise, diet, stress) approaches.
