Always Wondered - Why Do We Sleep?

In this episode, why do we sleep?  Is it really necessary... or are humans just the world's least efficient appliances?  We have the details.  Also - hear the unusual story of the Oreo.  It’s the sandwich cookie we know and love.    But surprisingly, it wasn’t the first!  We’ll follow the trail of crumbs to bring you the tale.  Plus - learn the origin of the phrase:  Saved by the Bell.  Who was the original “saver” and “savee?”  Join host Rick Peterson as he answers more of the questions you’ve Always Wondered about.
