Unfortunately not the Angelina Jolie type.
It’s one of the oldest commodities known to civilization and for good reason. It makes bland food taste better, and better food taste awesome! Your body also needs it to retain water, which despite the first world problem of water weight, is actually pretty damn helpful. Oh, and it’s used in food preservation.. just in case you run out of mac and cheese during the apocalypse or whatever.
Salt is so awesome, I’m not even going to bother to go through all the things its good for. There are a few reasons it’s at the top of my Bare Necessities list, and they’re not all related to how you can die without salt (but maybe you want to look at what’s out there on Wikipedia or something). Before I get into it, not all table salt has iodine, which can keep you from getting a thyroid problem (you don’t want that) and most would agree iodine is required for animal life to exist.
Aside from the biology of it all, when life really starts to suck, nothing can make a person start to feel human again like a decent meal and a hot shower. Get where I’m going with this? That’s right, win friends, make for easier diplomacy with hostiles, and maybe get some choice gear all because you have salt. It’s a lot lighter than gold, it’s easy to authenticate, and it’s easy enough to make (boil sea water) that people probably won’t get killed over it,. Also, really what are you going to do with gold? You may, however, be asked to cook.
And what better way to survive a harrowing situation than by making yourself a valued, skilled, human being? You know how to procure food from the woods? How to make salt? I know it sounds crazy, but really who thinks about salt these days?
If a person had enough cooking skill, they probably wouldn’t even need a weapon so long as they cooked for others. So to provide a bit of counter-point to my last entry.. if the crap hits the fan – don’t bug out, do grab the spice rack.
P.S. For those of you who are interested in salts, take a peek at Jar Of Salt, some great stuff over there!
