Threat plan.
Ask yourself the following:
What do you have that you want to protect?
Can be a person, place, thing, animal, mineral or vegetable.
A hierarchy of importance is good to develop.
Is your wife more important than your cat?
Is your fireproof safe full of legal documents more important than your computer?
Who do you want to protect it from?
Threats
Consider:
Actions taken by humans
Acts of nature (acts of your god?)
The passage of time
How likely is it that you will need to protect it?
Remember:
Privacy is important
Everything breaks down eventually, both man and machine, society and civilization
Will a hurricane demolish your mountaintop resort?
Will a landslide destroy your yatch?
Will looters ransack your home during an insurrection?
Historical weather and earthquake data is useful to know
How bad are the consequences if you fail?
What do you have to lose beyond possessions and people?
Reputation, freedoms, integrity, etc.
How much trouble am you willing to go through to prevent these consequences?
Will you go through worse if you don't prepare?
Will you have the courage to act when the time comes?
How many security cameras are needed to track a single cat? What about a married cat?
After you feel you have answered these sufficiently, you can begin to prepare to protect yourself!
In 1900 on March 14th the Gold Standard Act was ratified in America, forcing the dollar to be redeemable by the Treasury on demand for a fixed value in gold. It was abondoned in 1933 during the Great Depression (which really was not all that great from what I’ve read).
In 1943 Kraków Ghetto ceased to have prisoners. Less great than that depression.
1964 Jack Ruby was convicted of assassinating JFK.
1879 Einstein’s birthday.
1883 Karl Marx’s death.
