Magnetic pole drift has been observed for a while. The statistics are very broad, but it's not outside the realm of possibility that the N and S magnetic poles swap soon. It's also possible it's thousands of years away, still. It's still unknown if the flips occur really quickly and stabilize, or if it's an extended process with a few years of an unstable field, with many "poles" spread out and constantly moving while it's transitioning.

The Japanese were aware of the link between earthquakes and tsunamis when the last Cascadia event occurred. There are records of a tsunami in Japan without a recorded quake. It's believed this may have been Cascadia (early 1700's I think?). Indigenous people told the first European explorers about quakes, which probably had occurred not long before the explorers reached the PNW coast.

Australian shepherds are extremely intelligent. And you have to keep their brains occupied and challenged. Or they will use that brainpower to disrupt your life as much as possible.

After I was married, my wife and I wanted a low maintenance dog, so we got a Brussels Griffon. That dog could stare at a blank wall for three hours and be entertained. He was not bright. Took us forever to house train him but he didn't really enjoy playing like other dogs. He wanted to be petted. He'd bark when someone was at the door. That was the extent of his life. He snored like an idling chainsaw, though.

The US electrical is kind of weird. We have GFCI that breaks the circuit if electricity on one leg is different than electricity on the other leg (meaning current is leaking somewhere). This GFCI can be on a circuit breaker, on the receptacle itself, or on the plug of the device.

AFCIs are new and required in bedroom circuits. The early breakers would trip with certain arcing loads, like vacuum cleaners. They were annoying enough that an electrician I know said that almost all home owners would get the AFCIs installed, pass the electrical inspection, then replace the AFCIs with traditional circuit breakers. I think the AFCI technology is better today though.

Technology connections has a great video on this. It explores why light switches are "clicky". To spoil the answer, good light switches have mechanisms that fling the electrical contacts open and closed as fast as possible, to keep the electrical arc as short as possible.
