If there is a major disaster, even if the blood bank gets destroyed, donating blood will help you. See in the disaster you could be injured. You could loose a lot of blood. If you regularly donate blood you will know how that loss of blood affects you. And I believe that your body will regenerate your lost blood faster if your body is regularly exposed to blood loss.
I'm not quite crazy enough to say that epinephrine will help you survive the inevitable zombie apocalypse (you can go here for that). I'm just suggesting in a roundabout way that if you happened to be in a situation where something was trying to eat you, the increased heart rate and blood flow to your muscles brought on by a well-timed dose might just save your life.
Remember when I wrote about wheat in Why You Should Store Wheat for Survival?  For heaven’s sake, do not purchase wheat if you do not know how to use it.  Of course, it would not hurt to learn about wheat.  Freshly ground, it makes a heavenly loaf of bread the only problem being that it is so good you may eat too much and gain 50 pounds which would be another problem entirely.
#4 Knowing the right time to G.O.D is an ongoing struggle for me. I know there is no pat answer to this one. Rather, it takes observation and that “sixth sense” or “gut feeling” we are all born with but don’t always rely on. In fact I’m infamous in my family for saying, “You’ve just got to trust me on this, I’ve got a gut feeling”. Have saved myself & family from a few unpleasant issues with my “gut feeling”. It’s that whole idea of not leaving too soon but yet not waiting too long either that I struggle with.
In the previous decade, preparedness consultant, survival bookseller, and California-based author Don Stephens popularized the term retreater to describe those in the movement, referring to preparations to leave cities for remote havens or survival retreats should society break down. In 1976, before moving to the Inland Northwest, he and his wife authored and published The Survivor's Primer & Up-dated Retreater's Bibliography.
Precious Metals – Investigate this for yourself, but I find the arguments and historical track records against fiat currency and the current rumblings of Government wanting to take care of your investments for you very compelling. Gold is easier to transport with the high cost to weight, but you might have problems cashing a gold coin for a tank of gas. Silver is where I have chosen to invest in precious metals.

I know that in my own case and also with the majority of the readers on Backdoor Survival, hunkering down and bugging in will always be preferred to taking off into the unknown with our stuff.  For many, the choice to bug in has to do with family, health concerns or financial considerations.  That, plus the availability of stored supplies makes bugging in – or staying at home – the choice when a disaster strikes.

A portable, 2.6 pound stove fueled by naturally occurring scraps sure would come in handy after society breaks down. Voila: the BioLite Camp Stove. Feed it biomass like twigs, pinecones, or wood pellets, and the resulting smokeless fire from this portable grill can get a pot of water boiling in under five minutes. It also generates enough electricity to charge a mobile phone or other gadgets with a USB port. Included is a USB-charged FlexLight, a light with bendable stem that can be positioned to illuminate the cook surface.

Despite being marketed as a game with no pre-determined goals, Minecraft does have a basic structure, that of a scavenger hunt. While striving to build and expand their shelter, players collect various items and resources to add to their capabilities, attacks, and defenses, with many items enabling access to others. Over time, the player will travel to other dimensions to attain their goals.
Pense tells me this sitting beside the fireplace that heats the furnace-less cabin, necessary in the damp 40-degree weather. He wears a Realtree camouflage jacket, circular wire-framed glasses, gray slacks and black leather shoes. A sign above the fireplace reads: “Invest in precious metals. Buy lead.” Carved in a split log on the mantel is, “A country boy can survive.” The guttered roof deposits 30,000 gallons of Ozarks rainwater into storage tanks outside each year. It’s a prepper’s paradise.
For those that prefer to stuff all of their survival gear in a bug out bag and leave home, it’s not what I have in mind by writing this. These items also don’t cover prepper foods, they are just 8 types of prepper gear that I have acquired and have found other preppers also use just as much as I do. That, and they cover those basic needs for when the modern world hits a speed bump.
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
