Semi-automatic pistols. Typically capable of firing somewhere around 6-17 rounds from a removable magazine; reloading is very fast, provided that you carry another magazine with you. Their user interface is relatively complex, and some knowledge is needed to deal with potential misfires, jams, or to avoid negligent discharges - although the probability of any such issues is generally very low. (It's wise to avoid discount ammo and magazines.)

The stories of alcoholic beverages historically being safer to drink than unfermented ones are apocryphal at best; however, as any 17th-century sailor would tell you, the addition of some spirits to potable water that's been sitting around for too long will make it much more palatable. Liquor distillation was originally invented in part for medical purposes, and alcohol can be used as a solvent to dissolve medicinal herbs -- and also to knock out patients during good old-fashioned fallout-shelter surgery. High-proof alcohol can be used as an antiseptic, and it does a great job of cleaning wounds and preventing infection.
The FDA is making significant changes to nutritional label laws that are rolling out over 2017 to 2018. Because some manufacturers have changed early and others haven’t, in some cases we couldn’t be as apples-to-apples in our data analysis as we’d like, particularly around vitamins and minerals. So we did some backdoor math by judging the amount of fruits and vegetables in each meal.

There's 1 small thing and 1 large thing that, for me, saved it from being a 1 star. First the small thing, the mention of herbs and spices - I think this may be an item that many people forget about, but can make a poor situation go from "surviving" to "doing good". Secondly, the section on entertainment and education - I think this is an oft-overlooked aspect that will actually be very important, and again will affect whether one just survives or thrives.
