Single use IDs are less anon than making an encrypted note that only Bob can read and posting it right beside your public notes. This way Bob can hide in the annonimity set of all your followers.

Single use IDs are trivially discoverable by relay admins by looking at note retrieval queries. Only Alice and Bob will ever access a single use ID. That's an annonimity set of 2.

As soon as you feel a sore throat or a cold you can do any number of these:

Eat a raw onion 🌰

Stop drinking water, it allows the bacteria to spread more easily. Instead drink orange juice 🍊 because of its acidity. The longer your throat is coated in the acid juice the better. So sip it slowly throughout the day. Another option is squeezed lemon 🍋 with water. But don't use sugar, don't make lemonade.

Get as much sun ☀️ as you can. Vitamin D is geat.

Drink vitamin C.

Look at your tongue in the mirror. Is it white? Brush that stuff off while you're brushing your teeth.

Try very hard not to cough. Coughing makes the situation worse by irritating your throat. Focus on holding your breath when you get the feeling of coughing. Ignore the sensation of clearing your throat.

Now the contradiction to the one above. Cough! Hard! But into the sink with your mouth open, tongue out, neck tilted up and your torso bent over forwards. Create a straight passageway from your lungs to your throat to the sink. Cough hard but only if phglem is coming out. Don't do it when your throat is dry. When phlegm is yellow it's still infested. When it's white you've beaten the cold and you can stop coughing into the sink.

When you have a runny nose don't snort. Doing that transfers a runny nose into a throat infection.

Don't blow your nose into tissue paper if you have another option. Tissue paper irritates your nose. A better option is blowing your nose into the sink.

All infected fluids should come outwards. Don't swallow them. Blow your nose in public as much as you have to. Spit the stuff out if you have to.

Sweet. Didn't know about this one.

That's on my bull run bingo card
