Some day I will learn.  I go on vacation every year to the same place.  My parents have a little house on a lake in Michigan.  It is a great place.  I have a blast there skiing, swimming, fishing, jet skiing, etc.  It is always so much fun.  There is always one problem though.  I come back from vacation more tired than when I left.  Do not get me wrong.  I am refreshed.  I did get away and I was sure not look at email and so on.  But at the end of it all, I am just physically spent.  Some day I will learn how to manage myself so this is not the case.  Every year I get back and say why do I do that?
