While not all household conditions are perfect, be aware of the six enemies of food storage and do your best to mitigate their effect on your precious food supply. This means you should avoid storing food in garages that are 90 degrees in summer and 30 degrees in winter. I am repeating what I said before but it is important: empty your cupboards and closets of excess stuff and stow these items in the basement, attic, or garage. This will make room for you to store your food inside your main living area where the ambient room temperature is stable.
These glow sticks were terrific! Individually wrapped (means longer shelf-life), sturdy (none of ours were prematurely activated, which has happened with other glow sticks), gave good light. We purchased for use as interior emergency lighting in case Hurricane Irma hit us (she did) and we lost power (we did). There's no danger of fire and one glow stick in the hallway in front of the bathroom made the kids much happier. The white and yellow and green could be used for reading, or for calculating Yatzee score sheets. The red lights were not as bright as the others, but that's not always a bad thing.
Without water, you won’t survive for long. If the circumstances are perfect, meaning the weather is temperate, and you aren’t active, your timeline for survival without water is likely only as much as a week. But more likely, it is three days maximum. And in no way should one expect a significant catastrophe to leave you behind in a perfect scenario.
I just wanted to comment about an important thing that people need to remember (mistakes happen more often during stressful times): some of the advice given here have to be done AFTER the blast and the aftershock, not BEFORE them. You have to use the few minutes you have to get all the gear you can muster in such a short delay and run to the shelter you want to hide in.
After 9/11, my dad filled a duffel bag with some energy bars, a couple gallons of water, some penicillin, and a map. Amid scaremongering headlines about imminent anthrax and “dirty bomb” attacks in the city, he wanted to have some supplies on hand in case we needed to get out of Brooklyn fast. Were he to assemble such a bag today, he’d likely stumble on a number of companies promising a more wholesale brand of disaster preparedness: a box full of shelf-stable freeze-dried meals, to be revived from their dessicated state with the addition of boiled water.
