Nothing

Did you know that --

• Led Zeppelin is the only band in the world to have had all of their albums (each one) reach the top of the billboards?

• Rice is a fruit?

• Dragonflies mate while flying? I've actually seen this.

• though the course may change sometimes, rivers always reach the sea? (Led Zeppelin - Ten Years Gone)

We never know all that we think we know about the world. There is always something new to find out.

Oh, and take a look. An omniscient God.
