A new way to measure time

When I was in school, before the days of political correctness, we learned about B.C. and A.D.  These are measurements used to label time.  The correct meanings of these abbreviations are Before Christ and Anno Domini.  The more appropriate used labels nowadays are actually B.C.E and C.E. which stand for Before the Common Era and Common Era.  Back to my point, before learning the real labels, I had somewhere along the line been informed that B.C. was Before Christ and A.D. was After Death and both referred to Christ's life.  Of course, this is wrong and ridiculous.  If that were the case, Christ wouldn't have lived...which he did.  It is still worth mentioning because of its importance to grieving.  The term "after death" is something that I have become familiar with and realize will be a common theme in my life before now.  My life from this point forward will forever be divided into two stages...before death and after death.  Everything will be defined by whether she was with us, or not with us.  Even just two short months later, I've realized that this is the case.  I can't get it out of my head that this is a line in the sand.  Everything is either from before or after that time.
