"I bought these hand warmers for my winter emergency pack. I get stuck two or three times a year due to heavy snow. When it get's cold here, it gets incredibly cold. I've had to spend hours digging my car out. I put the HotHands in my gloves and also one in my shirt pocket. A couple of packs in the shirt under the jacket will help build up the heat and maintain it. What a lifesaver! I've used it only a couple of times and it works well each time."
Disclaimer: I haven’t tried this, I don’t think it’s a gimmick, but it’s something that’s on my wishlist to try regardless. Won’t charge much more than a phone, and probably not even that well, but if I have my emergency back up dumb phone on me plus this sucker, I can always call out for help so long as I’ve got the reception to. Even if I forgot to charge my emergency phone. Nice idea.
Mainstream economist and financial adviser Barton Biggs is a proponent of preparedness. In his 2008 book Wealth, War and Wisdom, Biggs has a gloomy outlook for the economic future, and suggests that investors take survivalist measures. In the book, Biggs recommends that his readers should "assume the possibility of a breakdown of the civilized infrastructure." He goes so far as to recommend setting up survival retreats: "Your safe haven must be self-sufficient and capable of growing some kind of food," Mr. Biggs writes. "It should be well-stocked with seed, fertilizer, canned food, medicine, clothes, etc. Think Swiss Family Robinson. Even in America and Europe, there could be moments of riot and rebellion when law and order temporarily completely breaks down."
Personal defense items – such as rifles and heavy firearms – are going to be increasinly hard to manage the farther you move from steady supplies. Ironically, it’s firearms that help acquire more food, provide personal protection, and deter others from attacking. In a SHTF scenario, heavy armament is only good within fortified areas. If you want to stay highly mobile, switch down to a .22LR polymer rifle such as the Savage survival rifle or similar. Lightweight, collapsible, and perfect for hunting game. Loaded with subsonic rounds, it can also be a lot more efficient than heading off a target with a loud 30-06.
