Sorry, Sir, Knowing myself is not possible

There are too many components in me and way too many unknowns.  I am learning about all sorts of unanswered questions about what is in the air I breathe and what effects they have or don't have on me.  My wife tells me about things that happened on trips we took together that I don't remember.

You may remember that an early Greek philosopher said that a basic principle in life is "Know thyself".  I agree that knowing myself is a good goal and is something to work toward.  However, that goal is not actually achievable.  Being beyond me doesn't mean that I should not work toward self knowledge but it does mean I am not going to get there.
