with a spanner in one hand and YouTube into the other
There are so many useful videos on this stuff, but unfortunately the majority of the population still seems reluctant to learn.
My son recently broke the string on the light cord in the bathroom. I opened it up in perhaps the naive expectation that someone would have designed that in such a way that the string can be reattached. Sadly it wasn't.
In fact when you open the interior plastic piece the whole thing springs apart and everything from the clicking mechanism to the electrical terminals explode in different directions.
Thankfully, someone had uploaded a video of a very similar switch and, after a few cross words (man I hate assembling mechanisms with springs), I had a new overhand knot in the string and all of the contacts, springs and terminals back in place.
I would, without doubt, drive down to a shop and buy a new one next time...
I think this kind of thing is much more commonplace than you think.
Never underestimate a young person and their phone. They not only use youtube or chatgpt to solve daily problems, but date, pay bills, and communicate with their friends using mostly videos/photos/emojis (and occasionally english).
Tangential, but made me think of this YouTube channel I like.
I have no plans to own a tractor but for some reason many others and I enjoy videos like this one:
I'm not sure the majority of the population will ever need, or even want, to learn to bleed fuel lines, so I wouldn't consider it reluctance. And I would wager that the majority of the (internet) population does engage in learning activities on the regular.
