What does it mean when you say, "I'm not getting any younger?"

If we are not getting younger, should we not be getting wiser with all the experience we garner on a daily basis? And if so, why is it then that most of us, still do not gain the wisdom to cherish what truly matters?

The world revolves, we have to work to eat and feed and clothe and house our family, yes.

Should we not do the same for our hearts and souls?
