My home does not have the US style light switches, they are UK style. On/Off labels printed on them would not make sense, since the living room, and basement, have switches on each end that control the same set of lights. The on/off position becomes reversed when you switch those from the other side, as described in the video.
We've added smart lights to the living room and outside. We can dim the lights (or change their colors) via smart app. Or, the lights can be controlled via voice, through the Amazon Echo. "Alexa, turn living room lights off."
US table lamps do have switches on the lamp rather than the cord. However, I heard that
@baimun uses, "Clap on. Clapp off, The Clapper."
Even though the US toilets only have 1 handle, the guts of the toilet can be made to operate like a UK toilet, quick flush for #1, flush hold for #2. When I was in Italy, public toilets were squatty-potties, which work even better than US toilets for getting those bowels moving along.
Not everyone in the US has central heating with forced air. Older apartments still have radiators.
When, I attended college at NAU, Flagstaff, Arizona, our rental house had a gas heater in the middle of the living room, no forced air. The house was old. I suspect when it was built that it only had a wood burning stove. During winter, we would crank that gas heater up super hot in the living room, yet the bedrooms were still cold. There was no air conditioning.
Our current home was built in 2001 by an independent builder. Forced air, central heat. Two gas fireplaces. No air conditioning. Two ceiling fans. We went without air conditioning for years, until my wife got pregnant. "We need air conditioning!"~wife. Yes, dear.
We have front loading washing machines as an option here in the US. IIRC front-loaders use less water. The nice thing about a top loader is that you can add clothes, even after they fill with water. However, top loading machines can get off balance during the spin cycle. Then, you have to open them up, move the clothes around, and continue the cycle. If I'm not there, my top loader fills with water, then agitates, to try to rebalance the load of laundry, then goes back into spin cycle, wasting a lot of extra water.
Air Fryers are all the rage in the US. Have those become popular in the UK?
