Oh man, YouTube is such a godsend when it comes to learning so many things but it also promotes terrible behavior for those looking to monetize information that would be better served up as plain text. Anything physical, such as learning an exercise or doing a car repair falls into the former category. On the other hand, there is a lot of very good talking head content that could be served up as plain text. Instead it’s gated in the form of video purely for YouTube monetization. I would gladly pay money for quality transcripts if that was an option.

A lot of the useful "how-to" content on youtube is created by people wanting to make a buck from creating the videos.

The first 10% is knowing what is dangerous enough that you need to look up how to do is safely first. I've worked on high voltage electronics - I'm still here because I knew to figure out safety first.

Same with gas (not petrol), it's the one thing in my house I absolutely would not under any circumstances touch.

Electricity I understand and how to work safely with it, water is the same (and the outcome isn't likely to kill you) but gas, gas will blow out the walls.

It's remarkable how safe we made it actually when you think about it but all of those lessons where often learnt in blood and strife.

Gas is crazy. The only time I needed to have gas pipes rerouted, it needed a change before the meter and the shut-off valve. So the gas company guys started the work ... by cutting a live gas pipe, intentionally lighting the leaking gas on fire, and welding a connection while the not-yet-welded hole was acting as a small flamethrower. Apparently that's considered safe to do with low-pressure small diameter pipes, but it seemed absolutely, totally insane.

burning gas never builds up to explosive concentrations, so it is what they do. I've heard other stories. A friend of mine cut a gas main digging, and when he called emergency they told him he should have lit a match instantly, it is too late now just evacuate the neighborhood. (the gas company was mad until he pointed out the gas main markings a safe distance away from where he was digging)

Nah you look for the youtube video after you've fucked it up.

Honestly though YouTube and the patient people who set out to show you how to do something is great (particulary the creators), it is an amazing resource for that.

Parent knows that

That's why it takes 110% of the time.
