So your're not terribly detail oriented. You are not rich nor do you own a car. You live in an Apt. Bldg. You are reasonably fit and have the proper mind-set to prepare. Is there a KISS method for preps? I offer these suggestions for a cheap, bare essentials 30 day prep per person. FOOD Store 30 cans of beef stew, 30 cans of mixed veggies, and 30 gal. of water . Do not store any food that requires water to prepare. LIGHT 1 hurricane lamp and 2 gal lamp oil. The oil burns 1/2 oz per hour. Batteries don't last long enough. Use a flashlight only when you have to search outside. HEAT The lamp puts a surprising amount of heat...especially in a small room. Otherwise, have a lot of warm clothing and wool blankets. No fires...too dangerous. Remember ventilation. SANITATION 5 gal toilet bucket and a box of garbage bags. Toilet paper based on your usage. Bottle of waterless soap. The stuff mechanics use will do. HEALTH Alcohol, pain killers, and bandages(dish towels, pillow cases ,or sheets can be used) to stop any bleeding. Anything more serious will require improvisation. SECURITY Throw some 2x4's under the bed. Use them to nail across the door and windows. In a pinch, you can use closet or bathroom doors for the same thing. Also have a hammer, nails, and screw driver on hand. I'm assuming your building will have fire escapes or firestairs for emergency egress. If possible where you live, have a shotgun for apt. defense, and a concealable high-cap pistol to carry if you have to go outside. You can assemble this stuff fairly quickly and easily. The food can be rotated into your daily food consumption when you need to replenish. Any SHTF that exceeds your supply will have become TEOTWAWKI. In that case, your are going to have suck it up and start getting out and finding what you need. Just remember to keep a low profile and try to stay out of sight as much as possible.
