Elixir Of Life

Frank Zappa once described it as "Food"
The Oromo people (an ethnic group found in Ethiopia, northern Kenya) would customarily plant a coffee tree on the graves of powerful sorcerers. They believed that the first coffee bush sprang up from the tears that the god of heaven shed over the corpse of a dead sorcerer.
And, Johann Sebastian Bach was inspired to pen the Coffee Cantata, about dependence on the beverage.

I know that I certainly couldn't live without it.

So, sit back with a cup of the blackstuff, relax and sooth your cares away with another's song of Woe and Coffee
