Riddles about Time

I'm going to be including riddles here in this "crazy wisdom" project because riddles are a great example of foolish wisdom, a skewed way of looking at the world which gives us new insights: the harder the riddle, the better the insights.

In this post, I'll be collecting riddles about time.

This thing all things devours:

Birds beasts trees flowers;

Gnaws iron, bites steel;

Grinds hard stones to meal;

Slays king, ruins town,

And beats high mountain down.

Time.

What goes up but doesn't come down?

Your age.

What four days of the week start with T?

Tuesday, Thursday, today, tomorrow.
