Cabin fever? What cabin fever? I actually work at a supermarket, and I see firsthand what goes on therein. I have to work nights, when the place is closed, stocking the shelves. (That is, if anything comes in to stock the shelves with--often little to nothing comes in in key sections, and it sells out in 15 minutes.) (I also see how little they actually sanitize--they do a lousy job cleaning the floors, store shelves are as filthy dirty as always, and the shopping cart handles never get touched except the cart(s) I use for damaged or misplaced items.)
In addition, I usually shop at a different supermarket. There, they have hand sanitizer for people to use, and they expect people to use it before entering the store. (I doubt it will stop coronavirus, but if I avoid catching the flu beforehand, I have a better chance with just the coronavirus and of having a wimpy case instead of a whopper.) I get to see firsthand the product shortages and limits. Where I work, "Limit 4" means total in that category. Where I shop, it may be "Limit 1 of each item per visit".
Besides that, I have the Internet (at least for now--they could take it away from us at any time). For now, I can view (and download--they don't like it, but the way YouTube keeps locking my computer with their rubbish cookies and then hounding me to use their malware browser, that is what they deserve) videos on countries that are too expensive to visit. I get to see Italy without paying the plane fare (and cancer scanners) to get there. I can see different countries through the world--the good (New Zealand, Germany, Italy, Britain, Paris--even though they are ruined now, I can see how they were before 2015), and the ugly (Nigeria, Israel, and the third world countries).
Cabin fever sets in for real when only Walmart is open, the whole Internet gets taken away, and Noahide Laws come in. I do not like the garbage Walmart sells or pushes, and I am expecting an easier time with coronavirus itself (and even with the panic and shortages that ensue) than with Noahide Law.
