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.
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 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?
It seems very weird to me that borax is so widely used in contact with humans in a variety of settings like ocular care and anti foot odor, because I use it as a flux in silversmithing and there are warning labels everywhere about the flux that it's reprotoxic, carcinogenic and mutagenic. Anyone knows why is that? Are my labels overcautious?
> Traditionally borax was used as a flux for brazing, but there are now many different fluxes available, often using active chemicals such as fluorides[9] as well as wetting agents. Many of these chemicals are toxic and due care should be taken during their use.
From the toxicity section (https://en.wikipedia.org/wiki/Borax#Toxicity) it seems like the concern is most about ingesting borax in large quantities or breathing in the dust. And also being cautious on potential health affects:
Since people are already exposed to boric acid naturally through their diets and water, Health Canada advised that exposure from other sources should be reduced as much as possible, especially for children and pregnant women. The concern is not with any one product, but rather multiple exposures from a variety of sources.
"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.
Clicking on this headline I knew for sure that the person was a woman, even if I knew nothing of the case. At some point we can't hide behind correlation is not causation anymore.
"Clicking on this headline I knew for sure that the person was a woman"
And this proves what exactly? Putting aside that you didn't "know" anything, all it shows is that you made a correct guess. On what basis? Well, probably because the media have been yammering on about gender bias for years. So you're confusing your own prior bias with reality. Congrats. You've discovered confirmation bias.
I can't find a pair of jeans with decent pockets yet. I resorted to buy hiking pants as they do have large enough pockets, but it's a bit sad to be wearing the same form everyday.
If you use regular soap on your face it's because the soap water has a high pH whereas your skin has a slightly acidic pH of around 5.5. So the soap disrupts the acidic barrier of your skin which prompts the skin to produce more sebum (acidic) to restore said barrier. [this is a simplification]
This happens on all your skin but it's more egregious on the face because the skin is more delicate there.
Are there any negative implications of using baking soda in you arm pits instead of a deodorant? I think it has exactly same effect pH wise as you have described about soap. It seems to be quite effective and more natural way of neutralising under pits odor than regular deodorants though and I haven't personally noticed any side effects.
