Years ago I read a comment here sharing how they'd taken to wearing amber glasses when walking at night, so they could be protected against the excessively-blue LED streetlights in their neighborhood. I bought amber safety glasses. They magically took the shock out of the bad headlights, but I also noticed that I wasn't seeing pedestrians until it was too late.
My local sunglass shop had some yellow fit-over safety glasses. I found they cut out enough of the blue from the bad headlights to take the shock out of the experience of driving at night. https://cocoons.com/shop/safety/lightguard-medium-fitovers-l...
The activists at /r/fuckyourheadlights figured out that the weaponized headlights put a little dim spot at the center of their headlight beams, exactly where the regulators measure the light intensity.
I used to wear these amber glasses for my motorcycle rides back when I was still riding. They not only did a great job of improving my visibility (be it subjective or not), but they also seemed to reduce overall fatigue for me. I should pick up another pair for regular driving though, thanks for the reminder.
Halogen bulbs do dim out as they age. The most common problem with modern headlights is the plastic covers get oxidized (cloudy) due to sun exposure. The cloudyness blocks some of the light from the bulbs, and scatters the rest.
The other problem is that some bulbs are just not very good - the filaments aren't properly positioned, or they don't have a good spectral output.
3M has a kit for polishing the haze off headlights with a drill, and for restoring the UV protection layer [0]. Dan Stern [1] told me it's really better to just get a new OEM headlight.
Human eyes are hypersensitive to blue-white light, but the old lighting science found that orange-yellow light is best for humans in a low-light environment.
I saw a car with terrible headlights, so I started a recording to see if there was flicker (which sometimes indicates that they're aftermarket). The light turned green, the car pulled forward & leveled out, and the headlights became less blinding. It was just a regular Hyundai SUV:
My theory is the manufacturers' marketing departments went to the engineers and said "we can't sell cars with safe headlights anymore, please make the next model's headlights seem brighter than they actually are."
Blue-white headlights are actually much less functional for human vision than yellow/amber headlights, so the engineers had to use the regulatory loophole to exponentially increase the output of their marketing-imposed blue-white lights.
“There are other rosins made from paper mills, where they grind pulp and extract
it with sulphuric acid. That rosin, you don’t want to use for potatoes,”
explains Baker [...]
That is interesting and confirms my suspicions that there is rosin and there is unsafe rosin.
While I think New Zealand made rosin would come from pine wood not pulp, no commercial producer is going to tell me if the product uses any toxic chemicals if they get the slightest hint I plan on cooking with it.
There is no row over Tylenol: there are comments on HN going back for at least 13 years how this drug would probably not be approved if an application was submitted today.
I've joked that if you're an old person trapped in a nursing home, one strategy to get yourself out of there is by cheeking a bunch of tylenol until you have enough, then taking them all at once. 4000mg/day starts to damage the liver. 10,000 mg can lead to liver failure. A pharmacist told me that Tylenol-induced liver failure is not a very pleasant way to die.
This thread was started by someone who commented on how Eric Engstrom (the co-creator of DirectX) accidentally euthanized himself with Tylenol: https://news.ycombinator.com/item?id=25424258
"[...] we can get away with things that we wouldn't be able to get away with nowadays. There's a lot of stuff that's like this; for instance, paracetamol/Tylenol would probably not be approved if it was introduced now because it's really easy to accidentally overdose on."

If the suggestion is that it should be outlawed, there's no reason to punish the vastly outnumbering population who can follow directions and take it safely. You can also accidentally kill yourself in a car every time you get into one if you're not careful. Many actually do.
A pregnant woman who ignores symptoms during pregnancy is putting the fetus at greater risk than one who follows her doctor's suggested treatment, which may include acetaminophen.

If you take two pills of extra strength Tylenol (2x500mg) every six hours as directed by the instructions, you’ve reached the threshold for liver injury.
Around 50,000 people a year (U.S.) visit the ER for having poisoned themselves with acetaminophen. A lot of people harm themselves without realizing it. I warned a friend about her Tylenol habit, which helped her connect “dizziness” to the Tylenol she’d just taken.
When I was helping my dad with various windows 10 problems, he was constantly touching the screen in exasperation. These touches only created more problems.
I deactivated his touchscreen. He’s never complained about his screen not responding like it used to.
I still see him touching the screens, but it doesn’t respond anymore.
Soy becomes edible when it's fermented into soysauce. Soybeans that aren't fermented are potent sources of phytoestrogens, which are plant chemicals that cause our tissues to swell sort of like estrogen.
Birds are better able to consume soy because they have faster metabolisms than humans. Pigs that are bred for food are able to consume soy because pig farmers don't care about the long-term health of their animals.
Most of the soybeans grown in the US are roundup-ready, so they're contaminated with glyphosate.

Harbor Freight's $2 yellow safety glasses are almost as good. I intend to stock up the next time I notice they're on sale for $1: https://www.harborfreight.com/yellow-lens-safety-glasses-668...
