Not much at this point. Since I am a doctor, I need a little more support for dental emergencies in the field when no dentist is available. I also built an EMP proof older pickup truck in case “bug out” or hauling supplies becomes necessary. Also, I became a licensed ham radio operator (general class) to be able to communicate when they flip the switch on cell phones and the internet. Ham is a great new experience and very empowering. All you need is off grid power, a radio, a wire antenna, and the ionosphere. They can’t shut that off, and I can talk from here to Shanghai and listen too.
