ELI5: Why are water fountains designed so we have to bend down to drink when we drink upright?
gpt
You see, humans come in various heights. Some can be 7 feet tall. Others can finish growing in the 4 foot range. Some humans are even said to come in child, ~~midget~~ little person, and baby forms. Still other humans require "wheeled-chairs" in order to be mobile, and are unable to stand. By placing fountains of drinking water at lower heights a greater number of humans are able to drink from them.
