Answer: A river.
A river has a MOUTH (where it meets the sea). A BED (the bottom). A HEAD (the source). And it RUNS constantly — but it never walks.
Every clue uses a word with a double meaning: one human, one geographical. Your brain had to switch from “body parts” to “landscape features” — and that mental gear-shift is what makes this riddle beautiful.
If you got this one, your brain thinks in metaphors. That’s a rare and valuable skill.
