DIY home surgeons will be excited to know epinephrine can actually be used with lidocaine (a numbing agent) to restrict blood vessels for faster wound repair. (Note: Cracked in no way condones performing self-surgery.) When sanitization resources become limited, the speed with which a wound can heal will have a drastic impact on survival rates. The longer a wound stays open and bloody, the more likely you are to get infections. Infections have historically been some of the most deadly and difficult-to-treat medical conditions, and even today they are not always easily survivable.
A supply of nonperishable food and water are a core necessity for every survival kit. Amazon.com offers several varieties of survival kits with emergency food for different situations. For the boat, car, or RV, high caloric density food bars are a compact and affordable way to stay safe. You’ll also find dehydrated meals in large quantities prepackaged compact bins for convenient storage. Waterproof survival kits are perfect for the basement, and contain up to three months of food for four adults.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
