Legionella won’t make you sick if you drink it, only if you breathe it in. It exists in clean drinkable water all over the world. It’s capable of hibernation and able to survive without nutrients for long periods. So it’s at least a potential risk any time you breathe aerosolized particles from water that is not hot enough to kill it. Any type of water heater that heats to 60 degrees Celsius will kill it.

This is a great idea if you are the only one using your shower. If you have 4 family members, each of whom likes a different shower temperature, it is less ideal. I think controls that allow separate on/off and hot/cold dimensions are best for most scenarios.

American customary units and imperial units both come from English units, so the US used various inconsistent English and other units in its early days. But the US never used “Imperial” units, which were not codified and put into effect in the British Empire until almost 50 years after the US had gained independence.

Not in classical Sanskrit. Vedic Sanskrit had pitch accent, which had been lost by the classical Sanskrit era. English has stress accent. But many languages do not have stress accent, and either have pitch accent or syllables are not accented at all.

This answer is spot on. I know this varies by state but in my state every intersection is legally a crosswalk, regardless of markings, and drivers are required to stop at them and yield right of way to pedestrians. This applies whether the pedestrians are in the crosswalk or appear to be attempting to enter the crosswalk. The area legally designated as crosswalk is the space between the stop sign and the road, and in the vast majority of cases in suburban areas is unmarked. There is no way in most of these that a driver will be able to see pedestrians or cyclists coming, especially from the right, unless they stop at that stop sign. The correct procedure is to stop at the sign, determine that the pedestrian way is clear, and then pull forward to the road. There’s almost 1 pedestrian death an hour in the US and most of these deaths are avoidable from the driver’s point of view just by following this and other legally mandated procedures.
