Rhinos are endowed with lots and lots of Marbles. This is a good thing, because We lose our Marbles all the time. Luckily, We get lots of spares as replacement parts.
We do wonder where our lost Marbles get off to. There are so many of them, and so many Rhinos have lost them, there should be a Marble coating on the planet of considerable depth. Why aren’t We wading through them on a daily basis?
Maybe they evaporate?
