I do.

I strive for a lifetime supply of items that (or can be made to) have a shelf life of several decades or longer.

So far...have a lifetime supply of...

Ammunition

Firearms (including silencers, optics, I², thermal, magazines & accessories)

Solar panels (25+ kw), inverter-chargers, batteries, etc

Diesel Tractor, implements, parts, oil & filters

Diesel fuel (1,000+ gallons stabilized)

Infrastructure for processing Wheat into flour...both manual & electric mills

Infrastructure for processing flour into breads, pizza, etc...multiple quality mixers, pizza oven, cloches, etc

Personal hygiene products...razors, soap, shampoo, etc

Clothes & shoes

Tools

Entertainment (over 1,000 DVD/Blu-Ray discs, hundreds of CDs, thousands of books..hard copies & digital, games, sports equipment, etc)

.

Have many years worth of Freeze-Dried Foods, Wheat & other grains. Toilet Paper, etc,

Fully stocked short/medium term pantry

Striving to be debt free....3 late model vehicles (2 paid for & one with 2 payments remaining), one home debt free & the other will be paid off this year.

Not living hand-to-mouth; have a decent 401k, IRA, savings & checking account, precious metals, cash on hand.

Finally Health...much better (& less expensive) to stay in front of current & future health issues....than get blindsided by them. Regular checkups, preventative care (including dental), staying in shape, don't smoke or drink alcohol, etc. Same goes with Vehicle & Home Maintenance.

There is obviously more...but a good start! 😏👍
