No special knowledge or skill is required to use this up-to-date first aid guide, though one might wish for a less academic tone of voice. “Emergency” doesn’t just mean accident, either—there are instructions for treating acute illness and delivering a baby away from medical assistance. An anatomy lesson is included to help you understand what’s going on, and there is a good bit of emergency prevention advice. Everybody should have this sort of knowledge available, preferably in their head.
