Margin of Death is a cautionary note on death being a slim margin away in the activities we engage in. The book presents safety and life-preservation tips to avoid, minimize, or mitigate accidental disasters that could rob people of their precious lives. Although the topic is serious and unnerving, this book is written in a humorous tone, perhaps to put readers at ease. Life is always at risk from a variety of sources, ranging from accidental, negligent, and deliberate acts. While natural age-driven death is accepted, we should minimize exposure to other non-scheduled, life-robbing incidents, a majority of which are manmade. A near miss is the one we know about, but the narrow margins are the ones we never know.
