^Time is Irrelevant? Read on: Here is the world's smallest
   living clock. We have a version of it in the middle of our
   brains.

   We are tied to this planet. Our bodies and our nervous systems,
   including our brains - are entirely linked to it. So much so
   that we come with built-in roughly 24 hours clocks that are a
   little out of sync with the days of today.

   It is made up of only 3 proteins, called KaiA, KaiB and KaiC.
   Kai is the Japanese word for Rotation along with other words
   like Ocean and Recovery.

   It resists temperature differences and a version of it exists in
   ALL Life.

   It's from bacteria. And we've been able to get it working - in a
   Test Tube.

   Is Time Irrelevant? We may choose to believe so but if it wasn't
   for the ticking of a Master Clock in our brains, we wouldn't be
   here to deny its importance.^
