The importance of sanitation, hygiene, and some minimal first aid capabilities are easy to overlook when prepping, so I suggest this as a sticky
topic. It's so easy to take for granted given our current state of luxury, and it is luxury compared to many other places in the world.
For example, how do you sanitize dishes without dish soap and hot water when you don't have the soap and you need all the water you have for
drinking? You can scour them with sand or something else gritty, wipe that off, and then let them sit exposed to direct sunlight for at least 3 hours
-- the sunlight will do a pretty good job of sanitizing.
Now remember, the saying is bullets, beans, *and bandaids*.Topical antibacterials are plentiful and not outrageously expensive right now. Finger
splints, slings, wraps, hell even "butterfly sutures"/stitches substitutes are OTC, and you can buy fish antibiotics OTC, and cheaply, these are
usable by humans -- shelf lives vary, and not because of improper storage but because of chemical "degredation", I have to find out more from my
wife about this.
Peroxide, isopropyl alcohol, etc. are plentiful and cheap *right now*. Tooth brushes, tooth paste, "Plackers" dental floss (cheap), Listerine (dual
purpose as the "unflavored" kind is also antiseptic. You get used to the taste, I've used it all my life, yes even as a kid. I sneak attack the
wife after using it, giving her a faceful of Listerine breath. Good times) -- who wants painful dental problems that can be avoided with preventive
care? Diahrrea can kill you - get Immodium or some other anti-diahrreal now. There are homeopathic alternatives, but having pills on hand that will do
the job is much easier.
Just one other rather unrelated tip: to supplement or even provide dietary calcium, you can store plain old Tums-type antacids, I think one or two of
those chewables provides around 70% of what you need per day.
Hopefully this wasn't an example of tl;dr
