Three and Counting - How long have we got?

I'm listening to 'A History of the Infinite' by Adrian Moore. Moore begins the with a rendition of Janacek's opera The Makropulos Affair.  Makropulos has the alexia of life, but finds too much 'living' becomes tedious, and eventually chooses to die.  Do we wish to live forever?  What hell!

Moore quotes Epicurus who say "death cannot touch us because while we exist death is not present, and when death is present we no longer exist."  Since death cannot touch us it cannot be bad.  

So much of human fear boils down to a fear of dying.  As Woody Allen put it, "I'm not afraid of death, I just don't what to there when it happens."  

For many there is an assumption that just as my experience of before I was alive feels 'mild', and uneventful, so I expect my life in the 'after life' to be the same.  There is nothing to fear.  I will be the 'great and eternal sleep'.

Here is an ancient belief, as old as religion.  To be, or not to be?

But what of eternity?  We don't know what existents beyond the constraints of 'time'.  We can only attempt to understand time in our world.  Perhaps other worlds have a different form of time?  We only know in our heart that we have been told to hope for better (even better).
