Why, for starters, would one want information on medical emergencies, plumbing mishaps, and auto malfunctions in one book? And what kind of an emergency is tree-pruning--or dental plaque? Most of this information belongs in a specialized manual--one set up, moreover, for quick consultation in an actual emergency, not designed (as this one is) for prior study. Moreover, much that is preventative--especially in the medical area--seems to have been assembled to present readers with a complete medical guide, not an emergency handbook at all. If one wishes, one can read--on large pages containing three columns of close-set, smallish type--all of the established risk factors in the development of atherosclerosis, for instance. Or, in the same format, learn about every form of door-frame, lock, and hinge. But, given the range of choice available, who would need to or want to?
