Class Reunion

My waistline's changed an awful lot,
   but my hairline's stayed the same.
My sex drive's lost a bit of pop,
   but my wife's not yet complained.

My eyesight's now a spectacle,
   and my crown shows off some silver.
My income's still respectable
   (but it ain't enough to kill fer).

My joints aren't jumping anymore, 
   and I'll sit on the pot and grimace,
strain in pain and groan and roar,
   but likely wind up witless.

But I will face my classmates
   over cocktails and hors d'oeuvres,
and pray that it's the last date
   that this event occurs!
