Well, covid hasn't made much of a difference. For many years my wife has chuckled at my insistence on being prepared. At first mainly food items, but more recently first aid supplies etc.
When people were panicking and desperately trying to find basic beans, rice and toilet paper, suddenly I went from silly to genius in her eyes.
We live in an area that is due for a 9+ megathrust earthquake that will likely cut us of from the rest of the world for at least six months. I've also been aware of what an EMP disaster could do for over a decade.
Yeah, we have at least a years supply of dried goods, probably more if we're careful, but I think skills are more important than stuff. I was taught foraging skills since I was a toddler. This region has a huge supply of wild plants for food and medicine and most, don't know how or where to find them. In fact, on interpretive signs the native people are usually portrayed as well nourished (slightly plump) because of this.
Skills. Rocket stoves are amazing, you can build one that is super hot, efficient and produces little or no smoke with a small pile of bricks or a few cement blocks. Medical supplies. Can you give an injection or do a basic suture on wounds? Take wilderness first aid and buy battlefield first aid manuals. My Doctor is a super prepper and I get to pick her brain about where to get supplies and what I should have. She suggested using pigs feet to practice stitching wounds.
Tools. Hand drills, saws etc. Buckets of nails. I like Japanese pull saws.
Defenses... hmm thats private.
