An internet forum like Lemmy is not the best place for medical advice. Most diseases can vary significantly from person to person. Lupus comes in multiple forms. The musician Seal has a form of lupus, and he's 61. Autoimmune disorders are very complicated, because the immune system is very complicated.
Your doctor should be able to give you guidance and "what to expect" type information. If there is a patient portal or email you can use, be proactive and reach out to your doctor with your questions. If you're in the USA, patients very much have to actively navigate this stuff, and advocate for themselves. Your doctor might give you a pamphlet or booklet. Read it.
I've never put much stock in the "we are living in a simulation" but stories like this make me wonder if one of the sim developer's kids is in here doing stuff.
Too many variables. There's two types of test, antigen and PCR. The chemical reactions in both can be impacted by ambient temperature and humidity, light exposure, air pressure (altitude), air quality (contaminants) and so on. At-home testing is far from lab conditions. False positives and false negatives are possible. I wouldn't put any stock in the timing.
One of my friends wears a lightweight (mostly mesh) cargo vest thing that looks good on him. But he's one of those assholes who looks good in anything. I would look like a doofus wearing it. Anyway, it has multiple pockets on the front.
In an ideal situation you want both assets and income in your retirement. 401k is one type of asset. Pension is one type of income. It's certainly possible to plan for retirement with just assets or just income, but having both is better.
I'm guessing the content offering algorithms are looking at your IP, browser profile, etc. and throwing stuff at you that it assumes you and "people in your area" want to see. Even with brand new accounts, they always try to figure this stuff out. It often gets it wrong, but that never stops them from trying.
A skeptic will seek more information. A cynic will just shit on it first and maybe (probably not) ask questions later.
