I noticed in the letter that there was nothing against holding the boasting sessions in the first place, and that field circus is business as usual with the precautions against unnecessary physical contact. How do they know that householders won't cough in their faces, either inadvertently or on purpose? Or they won't be in contact with high concentrations of viruses on surfaces in houses of studies? (Or spread viruses, even before symptoms show up, to healthy people in field circus?)
I would advise that they cancel these boasting sessions altogether, and suspend field circus. It simply is not worth catching or spreading this, or any regular flu, by going door to door with a message that is simply to help joke-hova to enslave the whole planet. Go online and do independent research on the whole religion--or, if you must, find digital streams of these boasting sessions. Last I knew, it is not possible to upload coronavirus via the Internet.
And, while you are at it, stock up on food and household supplies while you still can. Not a peep was mentioned in that letter, or in the translation, about that. Get those cleaning supplies, toiletries, and food now. Rice and legumes make sense to stock up on. Also, canned foods (normally I do not advise that because of the preservatives and MSG added, but this is not normal and fresh produce will not be available in a lockdown or supply cutoff). Canned meat and vegetables are available, and better than nothing. Also, you can get boxed potatoes and spices (whatever spices you like on them), powdered milk, quinoa and farro, iodized (but not fluoridated) salt, and other basic staples. Don't forget fun items--no need to make this an austerity exercise. Nothing wrong with crackers, cookies, candy, and the like at a time like this. Peanut butter is also good to have--and those burrito wraps are good for bread.
And supplements. If they are available where you live, I advise everyone to take them. Vitamin C (at least 500 mg per day; 1,000 is better), zinc (50 mg per day is advised), and herbs that help the immune system are a good idea. Echinacia, astragalus, oregano oil, and elderberry extract are good ideas, and there are probably others. Get at least 500 mg of magnesium and 6 mg of boron per day to help prevent whatever monosodium glutamate you get from ruining your brain--they prevent this from drawing too much calcium into neurons. Of note: In many parts of the world, you cannot get these vitamins and minerals at all, or they come in extremely tiny doses and are exorbitantly expensive.
Where is that information in the letter? I would advise stopping all boasting session attendance and field circus, putting the time and money you otherwise would have wasted therein into stocking up on basic groceries, and donate nothing to the Filthful and Disgraceful Slavebugger. For the time being, I even advise putting food and supplies ahead of buying silver or gold. Silver and gold make sense for a simple economic crisis, but will do nothing against a supply chain disruption where you can't get things at all.
