I understand. I should have been less specific. My curiosity is less about the eyeballs themselves and more about the entire apparatus of visual perception,
There is a study just released on why we dream, their hypothesis and conclusion is that because sight is the only sense that is not active when we sleep, dreaming prevents other areas of the brain from encroaching into the area reserved for sight etc.
Although dreaming must make use of the same sight receptors in the brain as when we are awake, I have some theories of my own as to the reason for dreams.

Now, that 'Times' have changed, it's OK to talk about herd immunity in the population.
https://www.nytimes.com/2021/01/27/...ronavirus-cases-testing-variants-vaccine.html
I mean, it’s not an artifact of testing for holiday travel and then a lag. There really are fewer cases each day in the United States. And we see that state to state to state. Literally every state except Rhode Island is seeing a decline in cases. So this looks like we really are seeing a turning point in the trajectory of the virus, that the number of cases has gone up to a peak and look like it’s coming down. We’ve reached the point now where about a third of the country has been infected. If you look at the total number of cases — 25 million cases. Basically, most epidemiological models now multiply that by about four to get the number of real infections we have in the country. So roughly we’re between 100 million cases and 110 million cases of actual infections, including the asymptomatic ones, which means that about a third of the country has been infected.
And when you reach the point in any herd, in any population where about a third of it is infected, the virus doesn’t stop, but the virus begins to slow down. Because in any herd, whether it’s a bunch of horses in a corral or it’s a bunch of people at a bar, about a third of them are immune to the virus. So the virus can’t just ricochet through that crowd as fast as it did months ago when everybody was susceptible to it.

So behind this good news decline in the pandemic is the kind of awful reality that the coronavirus has run wild through the United States and infected a third of our population and rendered a third of our population essentially immune.

That was an interesting study and does make sense given how quickly our brain can rewire.

There was another very interesting study about brain adaption where people wore glasses to mess up with visual perception of right and left. It was amazing how quickly participants adapted. It is called prism adaptation.

Lol, I wonder what other topics can now be discussed openly.

The following seems to suggest Sweden is at about 40%. At what point does an infectious agent disappear entirely?

Here's a graph they don't want you to see - Sebastian Rushworth M.D.

The problem may be summarised as follows: One (or more) infected person is introduced into a community of individuals, more or less susceptible to the disease in question. The disease spreads from the affected to the unaffected by contact infection. Each infected person runs through the course of his sickness, and finally is removed from the number of those who are sick, by recovery or by death. The chances of recovery or death vary from day to day during the course of his illness. The chances that the affected may convey infection to the unaffected are likewise dependent upon the stage of the sickness. As the epidemic spreads, the number of unaffected members of the community becomes reduced. Since the course of an epidemic is short compared with the life of an individual, the population may be considered as remaining constant, except in as far as it is modified by deaths due to the epidemic disease itself. In the course of time the epidemic may come to an end.

At what point will people start to notice that hospitilization numbers are not increasing?
We see it.

Things are reopening here again with ridiculous restrictions. The person(s) that limited capacity to a X value of 6 per venue instead of a low percentage capacity must be smoking something. With the case numbers falling so quickly compliance to such ridiculous restrictions will be low.

Governor Brown's new guidance says these businesses in extreme risk counties with over 500 square feet can operate with a maximum capacity of six people, not including staff. Leigh said financially, these restrictions don't make reopening worth it, but they're going to push through anyway.

"A six-person limit is very small. We seat 225, so six out of the space, it's not enough to make money, it's not enough money to get by on," Leigh said. "What's really important is to just keep connecting with my community."

"In the course of time the epidemic may come to an end."

Does this guy win the Captain Obvious award for this? Reminds me of the Great and Powerful Fauci, who doesn't come out and recommend vitamin D, but rather "I don't mind recommending." Perhaps all the shutdowns, and restrictions, mask mandates, and even vaccines are nothing more than CYA for the idiots in charge.

The guy said that in 1927, a different era obviously. :rolleyes: They created most of the modern mathematical theories of epidemics. How well they work in actual pandemics is up in the air.

My last vitamin D number dropped from 40 to 32ng/ml and I'm not happy about that!

Two years ago in Dec-2018 I started at 20 ng/ml and, because that's the bottom of the recommended range, started taking supplemental D3 (plus K2). By April-2020 I had my number up to 40. That's still lower than I would like, maybe 60ng/ml, and so I upped my dose. Now it's dropped to 32. That may be partly seasonal but I'm upping it big time to 25,000 IU per day for the next week and then half that ongoing afterwards.

I think seeing all three of the big metrics declining will be the turning point in peoples minds. First cases drop, then hospitalizations, and finally deaths. I think we are two weeks from the deaths declining significantly

I've never tested my blood levels, but take a 5000 IU D3 in a small gel cap. The only other ingredients are coconut oil and gelatin. I've read you need to wait something like 3 months before testing after a dosage change.

https://wset.com/news/coronavirus/fears-persist-even-as-cdc-shows-schools-can-be-reopened-safely
WASHINGTON (Sinclair Broadcast Group) — The parents, teachers and advocates eager to bring children back into the classroom got a powerful defense this week, with several studies showing how schools can reopen safely with mitigation measures in place.
...
While cases of COVID-19 have been reported in schools, the CDC concluded, "there has been little evidence that schools have contributed meaningfully to increased community transmission."

The CDC researchers found lower infection rates in schools than in the broader community and that children and their families were at greater risk of getting sick from attending social gatherings or having visitors in their home than in-person school attendance.
https://jamanetwork.com/journals/jama/fullarticle/2775875
However, the preponderance of available evidence from the fall school semester has been reassuring insofar as the type of rapid spread that was frequently observed in congregate living facilities or high-density worksites has not been reported in education settings in schools. Preventing transmission in school settings will require addressing and reducing levels of transmission in the surrounding communities through policies to interrupt transmission (eg, restrictions on indoor dining at restaurants). In addition, all recommended mitigation measures in schools must continue: requiring universal face mask use, increasing physical distance by dedensifying classrooms and common areas, using hybrid attendance models when needed to limit the total number of contacts and prevent crowding, increasing room air ventilation, and expanding screening testing to rapidly identify and isolate asymptomatic infected individuals. Staff and students should continue to have options for online education, particularly those at increased risk of severe illness or death if infected with SARS-CoV-2.

Morning news is that here in Ohio they have nowhere near (about 33%) of the vaccine they need for the round including school teachers, administrators and maintenance people. Like anything run by Federal or State Government it has become a cluster, well you get it. No surprises. I no longer bother with the news other than weather and lately they are not getting that right. :) Some are milking this for all it is worth.
