No idea.

Pretty sure it is actually just the longest international border in the world. I guess Chile and Argentina might be close, maybe Russia and somewhere, but USA Canada I reckon is the longest.

Agree - have previously fixed a wooden bed frame to drywall using 4 such anchors with no problems. Not as daft as it sounds - it was probably only supporting 20% of the bed and the weight on it, so unlikely to reach 100kg even with 2 people in/on the bed!

I teach at a secondary school in the UK, in a classroom with no external windows (but with air quality monitors). After 1 hour of 30 teenagers the co2 will be at around 2000-2500ppm which I can confirm is stuffy. Highest I’ve seen is in the next door classroom which made it up to 3800ppm back in the summer.

It really does make you (and the kids) feel really dopey, so not exactly ideal.

Not sure if you mean per year but mortgages are generally going to be over much longer time periods. A couple who I know are looking to buy somewhere new and are looking at getting £400k mortgage or thereabouts. With rates as they are now, and over 25 years, they’ll end up paying back £900k!

Not sure this comment deserves downvoting. As a teacher (UK) I get 13 weeks off a year, which is pretty much all time off (no expectation to prep/mark). Private sector friends tend to get around 4-5 weeks max. Similarly, the pension is far better than private sector pensions.

Whilst I might be able to change career for more money, I’m not sure it would be a net benefit, even for 50% more.

That said, the “work time” as a teacher is fairly full on, at around 55-60 hours a week for me, so that’s some form of trade-off. You do have to like doing it!
