Gettin' OldOne worth keeping
“Too old to cut the mustard.”
Past the age of keeping up.
In the same vein
All Gettin' Old →Been here since before the ground was.
His young and tender days are well behind him.
Outlived the oldest man in the Bible's own livestock.
Ancient, and showing it.
Gray-haired, sure, but far from done.
Admittin' the energy of youth has long since left town.
