Reminds me of Shadow Divers. IIRC they were instrumental in coming up with a breathing mix to counteract these effects

I suppose that's why 1 part of rum got mixed with 4 parts water and some limes.
The lime got added to prevent scurvy, which was a major problem prior to it's addition
Even with its addition as they didn't use fresh lime (some even boiled it) for many years. People got both lime and scurvy.
Scurvy: The Disease of Discovery by J. Lamb is actually quite interesting.

#143Is this why breathing pure O2 makes my head feel clearer?
Re: The anesthetic effect of air at atmospheric pressure
#144Just completed my deep (40m/120ft) diver certification. A significant amount of the course was focused on nitrogen narcosis, and how to handle/detect it. Apparently, some divers will start feeling the narcotic effect between 20-30m. Beyond 30m, a significant amount of divers can feel the effects. Beyond 40m is the realm of tech diving, with trimix (helium/nitrogen/oxygen) or even heliox (helium/oxygen). I know nothin…
>Except for helium, no other gas exists which does not have some form narcotic effect at higher pressures.
According to something mentioned in passing in a Scott Manley (amateur space youtuber) video about deep-sea diving: at high enough pressures you'll get similar effects from helium. It's thought that you can avoid this by subbing out the helium for hydrogen, but nobody so far has been insane enough to try.
I assume liquid breading is much easier at that point.
>The interesting thing about this research is that it sort of makes sense, and yet is very surprising. We’re basically continuously narked, we’re just so used to it we don’t even know.
I'd be interested in knowing how people are mentally when they're in spacewalk/Mir conditions. (1/3rd atmosphere, pure oxygen.)

In my high school days, we used it for Jell-O shots and drunk watermelons. Probably should have used vodka but ever clear was more bang/buck. I remember taking a shot of it once as a group “dare” type situation. It was as awful as you would guess
I've never drunk it. I don't like high proof alcohol. Once I worked in a very informal lab and we were always looking for alternatives to buying industrial chemicals. I was working with optics, and Everclear came up as a good alternative to denatured alcohol or isopropyl alcohol. My friend who ran a microscope lab said it was pure enough to clean optics... however, since it was illegal to buy in California, we had a…
Why would everclear be better than denaturated alcohol? Usually (I live in Europe btw) denaturated alcol is cheaper and has same proof of drinkable liquids.

are you using "nark" correctly? I've always thought that meant annoyed.
I am, however you’re not wrong. The main use of the word is either regarding annoyance, but can also mean snitching.
“Narked” in the scuba community 100% refers to nitrogen narcosis. See the company called “Narked at 90”.
Re: The anesthetic effect of air at atmospheric pressure
#147[1975]. Funny concluding paragraph: "Both theories of anesthetic action and the evidence cited in this report suggest that the nitrogen concentration in atmospheric air causes a measurable performance decrement in man, that the "nitrogen blanket" effect suggested by Miles[10] is a real phenomenon, and that human history has proceeded under partial narcosis. Perhaps this explains the current state of world affairs"
I hope this does not catch on. I worry about body hackers trying to live in a hermetically sealed homes with oxygen-noble-gas atmospheres.

"We’re basically continuously narked, we’re just so used to it we don’t even know." Just because one direction on the gradient means that we respond in a way that looks like a narcotic does not mean that the other direction will respond in the opposite manner. I'm sure the nootropics folks would have discovered being super not high by now if it were as easy as breathing a mixture that doesn't have nitrogen in it.
You'd hope mind-hackers would've explored & confirmed/refuted/quantified the effect, but stuff like this often lies underexplored for decades, despite hints like this 1975 study – which actually shows the 'gradient' of clearer thinking continues in the other direction, no hand-wavy extrapolation required. It's what they found! In 1975! How long did it take for society to fully recognize, & remediate, the effects of e…
CO2 is a weird one. The science is pretty clear the trend exists and it’s even built into the building codes for HVAC. But some how that information never gets connected to the people that would actually be interested in maximizing cognitive ability.
Re: The anesthetic effect of air at atmospheric pressure
#149Highly surprising mammals didn't adapt to this,
aren't nitrogen levels the same for 100m years?
Being 10% slower is actually a huge handicap,
and seems to be something fishy with the idea we
live permanently under influence without evolving
something like biological counters.
A rabbit that is 10% slower will face a huge
evolutionary handicap.

"Except for helium, no other gas exists which does not have some form narcotic effect at higher pressures." I assume the narcotic effect of fluorine, chlorine and bromine are basically unstudied...
You may have confused narcotic with necrotic.
I could hear the dice rolling in my head
