Not Trading

What's with wrinkled and saggy skin?  When did the firm stuff decide to simply abandon ship (or body in this case)?  What about receding hairlines and expanding waistlines?  Who said they could march to and fro without our permission?  And when did it become not okay to age gracefully rather than striving for perpetual youth?  I must confess, I'd take my 21-year-old body back but hooked up to my current and much wiser brain.  No amount of youth serum would entice me to give back what I have learned, the people I have loved, the places I've seen and the God I've come to know.
