I’ll take a person with common sense over one who has a lot of survival knowledge and skills. There is too much emphasis out there on wilderness survival. That will be a rarely needed skill set. More common will be urban survival, and suburban survival. Age and physical condition will have more to do with being able to survive a long-term disaster. As a senior I have difficulty convincing myself and my peers that hard core survival skills will be possible or necessary. We can only prepare for those things we feel we have any chance to survive anyway.

If you’re ordeal is an extended one you can lash the Ultimate Pro Knife to a small branch to create a spear for catching fish or small mammals. The pommel at the butt end can be used to hammer tent stakes and that little thing hanging from the lanyard cord is a powerful emergency whistle that can take over emergency signaling duties from the tactical flashlight or your long range walkie talkies when the sun comes up. A top-notch knife like this is essential survival gear.
Untold numbers of people wind up suffering frostbite, shock or hypothermia every year because they didn’t have adequate survival gear when the weather on their wilderness adventure took a rapid turn for the worse. But it doesn’t have to be that way. The Titan 2-sided Mylar Survival Blanket is light as a feather and yet capable of retaining up to 90% of your body heat.
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!
