Before you even think about self-medicating or treating wounds, you should get a reasonably systematic understanding of emergency medicine. I recommend getting "Wilderness Medicine: Beyond First Aid" ($10): it is accessible, focuses on situations where diagnostic and treatment facilities are limited, and goes well beyond the basics. Just as importantly, it avoids weird spiritual, homeopathic, or naturopathic claims that often creep up in prepper books.
I would add just a few things though, if you use creamer in your coffee add a few bottles of the powdered version, some dried fruits or a couple large bags of trail mix, pie fillings in a few fruit varieties (awesome in oats!), crackers are great for kids who won’t eat a tuna, spam or other canned meat sandwich but they may be willing to eat “lunchables” DIY of course!, and other all in one items like spaghetti O’s, canned stew, canned ravioli, and ramen. It may not be the healthiest solutions but if you need these items you will be exceptionally grateful you have them!
In fact, the influx had begun well before Trump’s victory. In the first ten months of 2016, foreigners bought nearly fourteen hundred square miles of land in New Zealand, more than quadruple what they bought in the same period the previous year, according to the government. American buyers were second only to Australians. The U.S. government does not keep a tally of Americans who own second or third homes overseas. Much as Switzerland once drew Americans with the promise of secrecy, and Uruguay tempted them with private banks, New Zealand offers security and distance. In the past six years, nearly a thousand foreigners have acquired residency there under programs that mandate certain types of investment of at least a million dollars.
In most jurisdictions, to draft a will, you don't need a lawyer; the only skill that comes handy is the ability to express yourself clearly and unambiguously. There are countless state- and country-specific templates available online; in many cases, to carry legal weight, the will just needs to be co-signed by disinterested parties acting as witnesses - or cheaply notarized.
