Being a prepper requires learning some of the old ways of doing things like building shelter, hunting, and making fire. But if you want to survive in an emergency situation, you've got to constantly update your supplies and skills. If you've been preparing a shelter or compound for years, you've got the drive. But have you kept up with new options for a safe and comfortable bugout? Go through your complete supply list once a year and replace or update everything you can with newer or better versions.
Whether you've got a one-week emergency supply of rations or have put away enough non-perishables to get by for months, your food supply won't last forever without spoiling. The average makeshift grocery supply will only last you a matter of months. If you're storing MREs, the commercial variety have an average shelf life of three years, while military grade is rated for a couple years more. Heat and cold will shorten the shelf life of all your foods, so trade them out and eat the older ones after renewing your storage supply.
When it's time to bug out, the odds are good your family will not all be together in one place. It's important for each of you to be able to communicate with each other, and independent technology is the key. In many emergency situations satellites will still be up and operational, so satellite phones will eventually be of use, even if the cell towers are jammed right away. If the electricity goes out you'll need to be able to charge your phone wirelessly, so keep a wireless charger or car charger on hand. Switch out your equipment for newer and tougher models as they become available, and invest in the new tough covers that render a phone waterproof and shock resistant.
Skills and Knowledge
You owe it to yourself to continue your education to improve your chances of survival once an emergency happens. As new and advanced methods for tasks arise, make it a point to learn these new ways of doing things. As you family grows and your environment changes, adjust your escape plan to account for new routes, roadblocks, or starting points. When new emergency tools are invented, buy them and practice using them until it becomes second nature.
With the worldwide bee shortage, you should learn about ways to pollinate future crops in your compound. If your family is growing, carpentry skills are valuable and easy to learn. Are there new types (or old) of weapons you can practice with? Is there a better type of vehicle to use on your land? Constantly look out for a better way to do things, from small entertainments to major life issues. You've only got one chance to get it right, so spending time now to improve could be the valuable way you ever spend your time.
