We all carry survival kits whether we realize it or not. The contents of a man’s pockets or those of a woman’s purse are nothing more than survival kits for a populated technological society. You have all the things you’ll likely need to fill your needs throughout your day. Keys, cash, identification, credit cards, membership cards and other items all serve to fill your needs as they arise. Luckily for us, most of our human needs are filled by technology and the remainder can be filled as you go with cash or credit.
