On our previous group page (Meetup), there was a discussion of how and why you might create a "Threat Matrix".
In simple terms, a Threat Matrix is a set of documents which collect and analyze all of the elements of threat about which you are worried.
This will vary, depending on the person who creates it...
This article goes into some detail of SOME (not all, IMO) threats which might enter into your fears and "prepper" awareness.
http://www.thesurvivalistblog.net/how-to-start-prepping-for-non-preppers/If you understand the process, you can extend the analysis to any element which is of concern. If you're paranoid (not necessarily a bad thing), your list can be large...
Since we each have a slightly different opinion on which "threats" are more likely than others, your Matrix can be structured with the most likely first and less likely farther down the list.
NOTE that sorting threats by what you believe is likely might push some of your "preps" to the point of never being done. This is dangerous.
Look for common preparations which can apply to many or all of the threats and work on them first. As you find time and money, address the rest of the items of preparation.
DO NOTE that at the end of the article there are several links to LDS (Mormon) documents which I find to be useful to just about anyone with a "prepper" mindset.
Just to get you started, my personal threat matrix, based on the "Rule of Threes", STARTS with:
Air Supply Failure (Three minutes without oxygen)
Shelter Failure (Three hours without shelter)
Water Supply Failure (Three days without water)
Food Supply Failure (Three weeks without food)
In My Opinion, these four "threats" are both most likely and most important for survival.
You can add any number of possible threats, any combination of which might cause one of the first
three four. So be prepared for the "big four" and you have some assurance that other, less likely, threats are covered (not totally, but you won't be left to die of asphyxiation, exposure, dehydration, starvation).
SO, read the article and add you comments to the thread.
