Sub-zero degree sleeping bag in the trunk of my car, plus a jug of water and some MRE-type food packs with water-activated food warmers. I grew up in a very rural area and got stuck on the side of the road in a blizzard for too long; I came out ok but it was terrifying. Now I live in a densely populated area that doesn't get blizzards but I still prep.

I used to let my toilet paper run nearly down to zero before I bought another pack. The pandemic lockdown months changed that. I used paper towels and liberated a couple rolls from work back in the day. Now I keep more on hand before triggering next buy. Never again.

I'm a good example of "we prep for our fears". I also do backcountry backpacking and everyone in that hobby does to some degree. I go out with a nurse sometimes and her first aid kit is nearly three pounds while mine is a couple bandaids and rubbing alcohol swaps.
