Except not quite, which is where the dark matter postulates come from. The Galaxies outer parts are spinning too fast and it would tear itself apart if you just modeled it after the solar system.

To me, deadly should mean "how many people did it kill in a given time period." Rabies kills basically everyone who gets it, but I would never call rabies more deadly than covid, because barely anyone ever gets rabies. Rabies just can't be very deadly because it can't infect many people, while covid is very deadly because it infects lots of people. If two diseases have the same infection fatality rate, but one is more infectious, it would be silly to say that it isn't more deadly.
Obviously, it's why we have specific definitions like case fatality rate and infection fatality rate.

Thanks for the explanation. Since you’re a virologist what steps should we take to prevent another coronavirus pandemic?

Autonomic dysfunction, metabolic dysfunction, all kinds of other terrible things. It's a great disabling event that people have collectively tried to ignore out of existence and it isn't working.
All cause excess mortality is way up too, which means covid is killing far more people after the acute phase of the illness, even when it was originally mild.

It's interesting and intuitive but relatively non-obvious. The galaxy operates with the same physics as the galaxy. Planets closer to the sun orbit faster than objects further out. So too are the objects near the center of the galaxy orbiting faster than those objects in the outskirts.
Edit for visibility: This is meant as a simple explanation and not a comprehensive one. There are far more details about the movement of things in the night sky than what I would expect anyone to know of or understand. Please take this for what it is - a very simple illustration - and not an absolute truth.

>killed most of the animals, which means there was very little sampling done
Is that a normal procedure? I would imagine that getting as much samples as possible would be a priority, especially since wuhan has a lot of research facilities.

But not in one direction, when looking at just the sun going in a “straight” line (its actually curbed since its orbiting but when looking at a small chunk it would look straight) then with the earth orbiting the sun while following this line earths actual path is that of a cork screw.

So even though the Earth and sun are going in the same direction, and are trevelling together, the earth gets more mileage than the sun.

I’ve heard about a lot of animals becoming covid reservoirs like minks but was referring to the reservoir or animal that it came from.

Reply to comment by Turtle2727 in In Parkinson disease, why doesn't the adrenal gland fill the dopamine deficiency? by Actual-Pumpkin1567
Well, it IS a problem if you have both conditions. The pheo, and the parkinson's, as the dopamine precursors can also cause the tumors to oversecrete their usual levels.
And also some wild mood swings. There are some pituitary paragranulumas that do some pretty evil things. Even if somehow modified, to be a dopamine pump, pheos/paras do not really have an advanced structure inside like and actual organ, and as such you would not be able to get reliable levels out of such a thing. Unless you somehow fused one with a computer/implant, and had the implant juice the thing as needed. An idea that's at least 30-40 years away.
Now, what is a pheo "tumor", about 1 in 12 at autopsy have some kind of nodule that might be called a tumor, non-cancerous, and usually not active. How many people with parkinson's are irritating this natural feature? The technology is kind of a pain here. With an advanced enough one you can sometimes, maybe, pick up the larger ones using the Philips Affinity, Epic, or similar class using a stander C5-1 and tweak the settings a bit. And much of what's picked up is just scar tissue, and random junk, as the living core is usually as translucent as the organs around it.
Other than this, you have to pickle someone with tracers, and the usual song and dance with various types of medical imaging. And it probably doesn't matter, as you still don't know it its just the adrenal cortex being hyperactive, or the poorly differentiated lump, your Pheo producing the excess catecholamines.
So, the neurologist will usually just tweak the mix of drugs, and hope for the best. Because bringing in yet another specialist to decide, even with all the lab tests, and imaging, that yes, that is a pheo.. Is going to be a 2-5 year ordeal, with the patient, insurance company, and everyone else involved getting more and more pissed off.
Because what is a patient with parkinson's going to do, while off meds, for months and months, while in the lead up the surgery, taking alpha and beta blockers, and hoping the surgeon doesn't have a "whoopsie". Only for the remaining adrenal gland to have the same problem 2 years down the road.
Now there is fairly good results with veterinary medicine for treating those in dogs. But for humans, its still a dice roll that the surgery will kill you from the process itself, or stabilization issues with the organ no longer there secreting. And the chemo only route is generally only attempted in proven cancerous tumors.

While true over longer periods of time, that first point is also a platitude that feels nice but is not necessarily true on a local scale. Delta was demonstrably more deadly than its predecessors. Also, while the disease is less "severe" in terms of killing people, it's still a nasty sickness that does very strange things to your body. A large proportion of people with long covid had a mild acute illness yet are still ending up with bizarre metabolic dysfunction or having their senses (smell, hearing, vestibular) damaged.
