We all know we are supposed to have a disaster kit with 3 gallons of water per person, extra prescription drugs, a jar of peanut butter and whatnot. I admit, I have never really done that. I figure I can drink the water in the toilet tank if I am desperate, followed by the water in the toilet bowl, and then I don’t really have a good plan after that. This Wired article says there is not a whole lot of science or evidence behind the government recommendations.

Recommendations for what’s supposed to go in these kits vary, but basically it’s a gallon of water per person per day and food, too, plus medicines, blankets and sleeping bags, maybe a tent, extra eyeglasses, lots of batteries, something to make light with, something to make fire with, maybe a hand-cranked radio…

Here’s the worst part: Nobody knows if disaster preparedness kits actually help. They might! You should still have a kit, if you can do it…

Is there stuff you should probably definitely have access to in your home? Sure. Copies of personal identification documents. Prescription medications. A good whistle. Lightsticks. Water purification tech. A crowbar. (The time you need a crowbar is the time you really, really need a crowbar.)
