42; 60; first time

what difference does age make?  If you were married 20 years ago and are still together or not?  or have never been married?  or never will be?  Does something happening make it the 'right thing' just by virtue of doing so?  Why are our lives so much alike yet so much different?  Why do some people seem to just stumble onto blessings?  Why is that me?  or is it more prescripted?  Does every decision we make affect the world at large as much as it seems sometimes (think: Butterfly Effect)?  Is it the large amounts of sugar that I've had this morning that's caused me to question so much?
