Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
Published first in 1841 in Essays and then in the 1847 revised edition of Essays, "Self-Reliance" took shape over a long period of time. Throughout his life, Emerson kept detailed journals of his thoughts and actions, and he returned to them as a source for many of his essays. Such is the case with "Self-Reliance," which includes materials from journal entries dating as far back as 1832. In addition to his journals, Emerson drew on various lectures he delivered between 1836 and 1839.
Preparedness refers to a very concrete research-based set of actions that are taken as precautionary measures in the face of potential disasters. These actions can include both physical preparations (such as emergency supplies depots, adapting buildings to survive earthquakes and so on) and trainings for emergency action. Preparedness is an important quality in achieving goals and in avoiding and mitigating negative outcomes. There are different types of preparedness, such as public health preparedness and local emergency preparedness or snow preparedness (i.e.: Snow Preparedness Teams - SPT), but probably the most developed type is "Disaster Preparedness", defined by the UN as involving "forecasting and taking precautionary measures prior to an imminent threat when advance warnings are possible".[1] This includes not only natural disasters, but all kinds of severe damage caused in a relatively short period, including warfare. Preparedness is a major phase of emergency management, and is particularly valued in areas of competition such as sport and military science.
