Two terms that are often confused are "teotwawki" and "shtf", but they have completely different meanings. When you are preparing for a shtf scenario, you are preparing for a short term event which will cause more inconveniences to your days than a life altering or society altering event. "Teotwawki" prepping is a completely different ballgame. Think about it...if "the end of the world as we know it" event were to occur, it could easily set civilization back at least 100 years.

You will do no one any good by doing this, experiment, just because any one person tells you that you cant do something a certain way, doesn't mean you cant customize it to reach your objective. Continue to inventory your supplies as well as your skills and continue to fill gaps in both.
