It's sneaking up on me pretty fast...

I've been very busy this week getting ready for a party I'm having this Saturday.  I'm calling it my 12-13-14 party because I like the sequential numbers in the date. It also, coincidentally, happens to be my 70th birthday which a friend kindly reminded of in a text today.  That's the part that's sneaking up on me.  How can I be 70?  It sounds so old.  I can't think where all those years have gone.  I guess I've been too busy living to notice that I'm getting older, except of course when I happen to glance in a mirror.  Now that is a dirty trick of nature.
