Common preparations include the creation of a clandestine or defensible retreat, haven, or bug out location (BOL) in addition to the stockpiling of non-perishable food, water, water-purification equipment, clothing, seed, firewood, defensive or hunting weapons, ammunition, agricultural equipment, and medical supplies. Some survivalists do not make such extensive preparations, and simply incorporate a "Be Prepared" outlook into their everyday life.
During the Cold War, Armageddon became a matter for government policymakers. The Federal Civil Defense Administration, created by Harry Truman, issued crisp instructions for surviving a nuclear strike, including “Jump in any handy ditch or gutter” and “Never lose your head.” In 1958, Dwight Eisenhower broke ground on Project Greek Island, a secret shelter, in the mountains of West Virginia, large enough for every member of Congress. Hidden beneath the Greenbrier Resort, in White Sulphur Springs, for more than thirty years, it maintained separate chambers-in-waiting for the House and the Senate. (Congress now plans to shelter at undisclosed locations.) There was also a secret plan to whisk away the Gettysburg Address, from the Library of Congress, and the Declaration of Independence, from the National Archives.
It turns out that when you're down to your last moldy hunk of bread and giardia-laced mud puddle, letting it all melt away in a cloud of smoke for a few precious moments can mean the difference between giving up and giving the rat (eating) race another go. If history has anything to say, it's more common than you think for people to happily give up MREs and gunlord harems in return for hastening their ends with carcinogens wrapped up in tidy paper packages. In traumatic situations like war, cancer sticks are often valued more highly than food. Even in the current (more or less) pre-apocalyptic global economy, cigarettes are one of the stable forms of currency.
Your run-of-the-mill shoe stank might not pose much of a survival threat, but trench foot certainly will; baking soda is great at absorbing the moisture that might otherwise literally cause your feet to rot off your legs. As for the health of your teeth -- it will be pretty hard to get through your day's rations of homemade jerky and hardtack without some high-quality chompers. And you certainly don't want to rely on that pesky fluoride that will "kill your brain over time" (um, what?).
