Prepping?

As I am reading lots of blogs for the blogathon, I am wondering what prepping is. I wonder what the difference is between preparing for disaster and preparing for the end of the world as we know it. You need the same skills for both, as both are disasters of some sort. The disaster usually has an end and the end of society will not. Stock piling food and learning skills like canning, sewing, gardening, first aid, and bartering will get you through a disaster like a flood, fire, or tornado. Learning how society works will serve you better in the event a societal disaster strikes, it is important to know how people work together to serve a common goal.
