I grew up during the Cold War, my daf was in the AF and they were told to have 3 months of food on hand. I laugh now because the 8 of us coldn’t have lived 3 weeks on what we had and it seemed like a lot.
OTOH, my MIL had home canned goods from years back and could have lasted for months.
Not counting the catz (they get fussy about being included on the protein list), I'm good for months and months. I've been living that way for a long time, and spent a year and a half after the market crash of 2008 mainly living on stored and foraged and grown food. Squirrel population took a big hit in 2009 around here. ;)
