A long sleeve 50 UPF surfing shirt. I did get it 5 or 6 years ago, so it’s done it’s time. I took it to Greece recently, got burnt, looked online and saw that they don’t last forever. Putting 2 + 2 together I think that the sun marks on my shoulders have probably been caused by the last few times I’ve been in full blown tropical sun erroneously thinking I was protected.

The Stone Age persisted for roughly 3.4 million years, but it took barely a couple of thousand years to 'find' Iron.
Good point, but as a counterpoint: metallurgy ‘developed’ on seemingly isolated parts of the globe (at around the same time). It’s an entirely plausible coincidence, but a hefty one, that Native American tribes created the first copper tools ever at around the same time that Middle Eastern tribes did, and no one had ever done something similar before.

Agreed, but our understanding of the chronology of human achievement is limited by what has survived through the ages. Prehistoric does not mean rudimentary: Göbelki Tepi predates Stonehenge by 5000 years. More time passed between the time that site was active and flourishing and the construction of Stonehenge than between Stonehenge and now, and we have no idea who built (the much more complex) gobelki tepi or how or why.

The most logical explanation
Thing is, we know next to nothing about the people who built it, let alone their technology. Modern views are that they were primitive and only had the most basic creations we can imagine, the likes of which weren’t even invented by our species but by a preceding ape (homo habilis made tools 2 million years ago, neanderthalis made elaborate clothing and jewellery to decorate their dead in complex funeral rites tens if not hundreds of thousands of years ago).
We believe homo sapiens sapiens has been physiologically pretty much the same for a couple hundred thousand years now. Was it really only a few thousand years ago that humans got creative and industrious enough to create wooden machines to lift things?
Not directed at you personally, but modern archeological convention strikes me as having a Victorian attitude to science, equating a (perceived) lack of cultural sophistication with an actual lack of cultural sophistication.

built by people thousands of years ago using nothing but their ingenuity and their own strength?
They nearly certainly used large tools, and probably beasts of burden (or slaves). If they were clever enough to figure out astronomical alignments, they definitely would have been able to fashion scaffolding and levers.

Today’s rant featured his fear about the possible change of government and how their stupid Goal Zero policies are going to wreak havoc on the price of fuel because they won’t continue increasing oil extraction in the country. That segued into how human overpopulation is the problem, ‘humans are a pest on the planet’, and 2 billion are enough people and the rest ‘should be culled’. He’s at least self-aware enough to realise that ‘some people may call (him) a fascist’.
All quotes verbatim.

New job, new boss. Seemed alright during interviews. In today’s 5 hours of work he’s already complained about his council and his taxes not doing anything for him, about his fear of “Muslims” harassing his wife, about “soft liberal types”, about the Labour Party (in the 90s), and about govt transparency somehow being a bad thing.
I don’t think we’ll work together for very long.

Good time to invest in bike helmet companies. His helmet was trashed, and he tore through the jersey so he has a bad scrape somewhere as well as the bruise.
Speculation as to cause?

Is the threaded part metallic, composite or carbon? Using an alloy insert wouldn’t be difficult, so it’s an odd choice to use threaded tow-based discontinuous composite (aka ‘forged’ carbon fibre) for a threaded safety critical part, but it can be made quite strong. 🤷♂️
Quite a few calipers operate(d) on a similar principle, with duly mashed cables as a result. Not an elegant solution, at least.
