The list author says: "Lots of other people make these lists to prepare for collapse of civilization, zombie plague or other post-apocalyptic scenario. This one is just some stuff that I have for the everyday (and not-so-everyday) problems that might crop up. It all fits somewhere out of the way in my backpack that I take to work/the gym/the playground/carry my laptop in/etc. I spend most of my day at the office, my kids' soccer practices, or running errands. But I live in Colorado, so I usually have to drive through some backwoods areas too. This stuff all comes on handy at some point, and lots of it is dual-use (at minimum) just in case the unthinkable should happen."
"I've made my own to keep in my pack, but this one's small and seems. Just the esentials: band-aids, antibacterial wipes, tylenol/ibuprofen, etc. This is great for all of the everyday ouwies that my kids (and I) seem to get."
"Iphone, Droid, Blackberry, whatever. Besides a billion apps, mp3s, podcasts, e-books, videos, internet, etc these things have GPS and a map function. Which means I can store maps of where I'm going, or download them as long as I have service. You can even get a compass on there. Because I tend to get lost a lot."
