This Smarter Every Day video demonstrates how dumb you can get under (less mild) hypoxia (and why it's important to take care of your own oxygen mask before others') link to this video

On “Why is cognitive function impaired at high altitude?”
Destin from the 'Smarter Every day' YouTube channel did something similar (in a PSA-sort of style), and it's partly funny, partly scary to watch: link to this video

On “The strangely successful history of people mailing themselves in boxes (2015)”
30-40k ft is absolutely a problem. Even if you remain conscious, you're completely unable to think coherently and generally have no idea what you're doing. Stay there long enough and you will unquestionably suffer brain damage and probably death as well. SmarterEveryDay did a good video about hypoxia training that demonstrates the very rapid onset and severe effects of hypoxia at cruising altitudes: link to this video

On “Decreased CO2 during breathwork: emergence of altered states of consciousness”
Destin from Smarter Every Day (YouTube) has a wonderful video demonstrating this effect 0. I’d recommend watching the whole thing, but you can see how much of an effect it has starting around the 6:00 mark. 0 link to this video

On “What I Learned from Executing Two Men”
Does anybody have an opinion why not to use low pressure as a method killing 0? All the failed executions by electrical chairs and administered chemicals makes me think about a safer and more human method. Just theoretical question, not advocating for anything. 0 link to this video Edit: Typo

On “Woman Partially Sucked Out of Jet When Window Breaks”
And we should all remember to keep our seat belts on. And also seriously you should put your mask on first quickly before helping others. Your ancestors didn't experience a lack of oxygen without excess CO2 so you'll only experience the later as feeling that you're running out of breath. Without oxygen you can become too stupid to put on your air mask1, then black out and die without noticing something is wrong. And if you're working in a lab with a cryogenic liquid that spills don't try to be a hero, just get you and your lab-mates out of there. 1 link to this video

On “A man who ran out of air at the bottom of the ocean”
…w would you correct for that? Can you correct for hypoxia for me?" Destin just sits looking confused "Alright sir if you don't get on oxygen, you're going to die. Go to your regulator, get all three switches on your regulator..." Destin looking even more confused: "I don't want to die" >> they get him back on O2, fixing everything in seconds link to this video…

On “Wim Hof’s teachings about breath work and the health benefits of cold plunges”
…easily be deadly. - Doing the same without hyperventilation is much safer. The difference lies in the fact that our ability to sense our limits are almost entirely due to CO2 buildup. We actually almost can't tell when we run out of oxygen, it's why pilots are fine one second and pass out the next when they don't notice that the oxygen runs out ( link to this video ). Hyperventilating reduces your CO2 but leaves oxygen saturation almost unaffected, which for an unexperienced person is equivalent to doing a blind walk next to a cliff, and removing the barrier.…

On “Covid-19: politicisation, “corruption,” and suppression of science”
Oh, so it is in fact just geoblocked? That's annoying. It's still down for me (and my EU VPN). Does the site list deaths by date of report, or date of death? Hopefully the later, so we can just check back in a few weeks. Anyway, in general this "dying breath" stuff doesn't really tell anyone anything useful. For starters, how much faith do you really want to put in what people say when they're so sick they're about to die? Hypoxia significantly affects mental capacities: link to this video For all you know, these people don't actually realize that they're sick at all.

On “I Bought a CO2 Monitor, and It Broke Me”
There was a video I watched years ago where someone was on an airplane and basically tested how they'd react with a lack of oxygen. It was pretty crazy. He knew he needed oxygen, but didn't feel like he needed to do anything about it. I think it was this one: link to this video

Time of useful consciousness would be another interesting number to add. Here's a table of average times published by the FAA for a gradual ascent: - 18,000 ft; 5,500 m: 20-30 min - 22,000 ft; 6,700 m: 10 min - 25,000 ft; 7,600 m: 3-5 min - 28,000 ft; 8,550 m: 2.5-3 min - 30,000 ft; 9,150 m: 1-2 min - 35,000 ft; 10,650 m: 30-60 sec - 40,000 ft; 12,200 m: 15-20 sec - 43,000 ft; 13,100 m: 9-12 sec - 50,000 ft; 15,250 m: 8-10 sec Here's a demonstration of the effects of hypoxia and time of useful consciousness done in a hyperbaric chamber by SmarterEveryDay: link to this video 1: link
