What is a Technology Fast?

Normally a Fast is an absence of all food, sometimes even drink for religious or medical purposes. But what is a Technology Fast? Now this is an entirely different question altogether. This is an absence of all, if not most of the benefits of modern living for the duration of a 24 hour period. The goal is not just to allow one to appreciate their surroundings more, but it is to obtain a better understanding of oneself and their state of existence.
