"The average person uses 101.5 gallons of water per day"
Replace "person" with "Westerner".
I wonder how many fewer gallons of water a person would use per day if they themselves had to lift from a well and carry home all the water they wanted to use (1 gallon = 3.79kg water). This is how superior ancient life was. I am not against labour-saving automation of water delivery in theory so long as it does not lead to more water used, but if in practice it leads to people using more water than they actually need to, it becomes decadence.
