Why You Should Put YOUR MASK On First (My Brain Without Oxygen) - Smarter Every Day 157

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] [VIDEO]

To take this tangent even further afield... Here's an actual real life demonstration of why you should put your oxygen mask on first: [VIDEO]

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') [VIDEO]

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: [VIDEO]

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: [VIDEO]

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] [VIDEO] Edit: Typo

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 mask[1], 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] [VIDEO]

Destin at Smarter Every Day shows you the effects of hypoxia and why you should put your mask on first before helping a child or other passenger. [VIDEO]
