First off start building yourself a “Shit has hit the fan and I need to get out of dodge.” kit to keep in your car/close to your door so you can grab and run if it gets REAL bad.
Keep it stocked and up to date (certain first aid items are only sterile for a year. Antiseptic Creams like Savlon go VERY bad when they degrade)

Additional components; heavy duty needles and some aramid or Dyneema thread (brand name of the high density polyethylene rope that’s strong as Fkk) for repairing things that need structure.
Also get yourself on an emergency first aid course, one that covers serious injuries and stopping bleeding is more than worth any price you pay for the lessons.
Learning practical skills like simple electronic repairs (I’m not talking about house electronics, that’s how you meet god in one of the most painful ways possible), how to diagnose car issues how to effectively tie knots in rope, and a few sewing stitches to repair clothes.











One of the main reasons why I love watching people like Primitive Technology on the 'toob.
Chap goes through the process of building shelter from nothing but the shorts keeping you decent, and access to a bit of yard with a creek that has some good clay and sometimes grows iron eating bacteria.
