For those of you who have an iPhone, a handy feature that helps with phone lighting at night is "Reduce White Point" in accessibility features. It is different than night mode and reducing luminosity to the minimim and I find it's a nice addition. You can put it in the control center for fast enable/disable should you need it. I have trouble sleeping and I found this helped, albeit marginally.

They know it affects the immune system.
They expect repeated exposures to mean the west is weakened with lots of people unable to participate in the economy, while their population won't have that issue.
It seems unlikely that "weakening the west with lots of people unable to participate in the economy" is the goal here, since the zero-covid policy also does exactly that, both short term and long term by weakening the economy and mental health of residents.

I heard this talk at Microsoft about outlier success, and while somewhat of a throwaway comment, the speaker mentioned that the vast majority of the low American standing in those international math score comparison is due to motivation. Summarized, he said when taking the PISA math exam used to benchmark countries on their academic rankings, we always hear how the US is nearly last among developed countries, but if you compare how far different county’s students get on the 120 question end-of-assessment question (with nothing to do with math), THAT ranking almost perfectly lined up with the math assessment ranking.
Overall, if true, the weak showing of the US seems to be in large part a matter of motivation and persistence than what we’d traditionally call math ability (so maybe we need to change our thinking to include grit to stick it out as part of the math curriculum).

Well ability and motivation can also have a causation relation in both ways...

I think you misunderstand, it's where the attack comes from, not goes to. Unless Australia goes to war with Antarctica, every possible attack on Australia would be sailing approximately south towards it from a more northerly position. If you want to stop Chinese ships from sailing into Sydney, you must engage them north of Sydney, ideally a lot further north.
Interestingly, China has been developping bases in Antarctica recently.
Citation needed; I know research into psychedelics is difficult due to restrictions, but anecdotal evidence is not enough to start recommending it without listing the necessary caveats.
I mean "Ivermectin has been shown to significantly help with Covid" has the same weight to it, and I'd never recommend anyone take horse dewormer. Maybe if they had worms and it was the only thing available.
Lion's Mane mushrooms are not psychedelics though

So much security that not sense.
I attend college football games. Everyone goes through security. Outside security we pack up in masses of humanity outside the gates waiting to get through the inevitably slow security.
It would be far more effective to do something at the gates dude to the density of humanity there where there is no security ... than in the stadium where people are actually more spread out.
If someone did want to do something at such a sporting event, nothing is stopping them from doing it at the gates where there is a reliable and unsecured mass of humanity, and I don't think anyone is bothering with that ...
I used to wheel my grandfather into games on a wheelchair... they didn't check anything, just waved you through. A wheel chair sized bomb would be easy to bring in, but you don't even have to bring it in.
We have secure ID schemes that I believe most if not all of the 9/11 attackers would have qualified to get ...
In the US we don't have mass terrorist events that any of this would prevent.
Why do we keep subjecting non-terrorists to these systems?
What are we doing this for?
> What are we doing this for?
I think we are doing these mostly useless things in order to signal that as a society we're somewhat careful in order to reassure people. I feel our best security defense is that most people are not terrorists?
The more likely effect seems to be the result (again, as boric acid) on fertility.
https://en.m.wikipedia.org/wiki/Boric_acid#Toxicology
"Although it does not appear to be carcinogenic, studies in dogs have reported testicular atrophy after exposure to 32 mg/kg bw/day for 90 days. This level is far lower than the LD50."
The base toxic dosage (on the order of multiple grams per kilogram bodyweight) is the reason it's typically labeled as very safe.
The labels and general knowledge passed from trainer to trainee insist on the reprotoxicity of the flux, which as you point appears to be at exposure levels far below toxic levels. I wonder if the safe label of boric acid for feet is made looking only at the general toxicity of the product, leaving aside potential reproductive issues that might arise with repeated use of small quantities?
Borax flux is a mixture of boric acid and ammonium chloride and then you are dumping it into molten metal where it likely combines with metals and gives off gases.
Kind of different than just boric acid itself?
At least in silversmithing I don't recall flux to contain any ammonium chloride it seems to be a solution of borax alone.
Or is it just goods, and in that case why focus on goods?
