As one gets older - I am now 67 - I suppose thoughts naturally turn to the end of life. It comes to us all, but we prefer not to think about it.
I honestly have no idea and the most likely is we'll not be aware, as we were before we were born, so it may not matter. MAN has a real problem with finality, and nearly every religion has talk of life after death. It bothers me that some are so certain about this. At the moment I have an open mind. Like so much in this universe, or even multiverses, we really have no idea.
