It is worth noting that many personal finance experts advise against hand-picking your investments. Instead, they advocate a process known as "indexing": buying into an investment vehicle comprising hundreds of stocks, structured to represent the stock market as a whole. The proponents of indexing have a point: most people who try to pick individual winners in the stock market usually fare no better than an index fund. But in the context of prepping, I think this is advice is flawed. To remain calm in tumultuous times, it is important to maintain a firm grasp of the merits of your investments. One can convincingly reason about the financial condition, the valuation, or the long-term prospects of a paper mill; the same can't be said of an S&P 500 index fund - which, among other things, contains the shares of about a hundred global financial conglomerates.
Of course, marketable hobbies aside, some of the more determined preppers pursue interests such as martial arts, pro marksmanship, bushcraft, paramilitary combat tactics, and other extreme survival strategies. Such talents can be quite useful in a couple of plausible if unlikely scenarios - but their major disadvantage is that during a simple economic downturn, they won't put bread on the table or pay your bills. It's not unwise to give them some consideration, but be sure to balance it with more pragmatic skills.
With the rules internalized, you are extremely unlikely to cause unintentional harm. Keep practicing at least twice a month until you get good, and then go to the range at least several times a year. Try to use practice ammo with lead-free primers and clean bullets (e.g., RUAG Copper Matrix, Magtech Clean Range, Winchester Super Clean, Federal Ballisticlean, Remington Disintegrator, Federal American Eagle TMJ, Federal Power-Shok Copper) and avoid tracking lead residues from indoor ranges back home - especially if you have small kids. Always wear hearing and eye protection, too.
This may sound like a good argument for putting all your money into freeze-dried meals, medicine, shovels, and other survival supplies. But of course, that decision would become a huge liability should the apocalypse not come, or simply not come soon enough: you probably can't pay a roofer or a dentist with a pallet loaded with ammo, cigarettes, and canned ham.
When I am going through a grocery store gathering survival food, I get some strange looks from people close enough to hear me muttering under my breath as I discount items. Phrases like “not enough calories”, “needs more fat”, not enough carbs”, and the like roll off my tongue frequently. The truth of the matter is that what we consider to be a healthy diet in normal times is probably inadequate in a high stress, very active, crisis situation. There is a reason we like carbs, and fats, and sugars, and that reason is our body needs these things. The human palate developed in times when being physically active and dealing with life threatening events was the norm, and when a steady supply of food was not a guarantee. Hence the urge to get all we can when we can, which leads to rampant obesity in modern sedentary times but is adaptive to survival in harder times.
Civilians such as forestry workers, surveyors, or bush pilots, who work in remote locations or in regions with extreme climate conditions may also be equipped with survival kits. Disaster supplies are also kept on hand by those who live in areas prone to earthquakes or other natural disasters. For the average citizen to practice disaster preparedness, some towns will have survival stores to keep survival supplies in stock.
