That’s the main wondering when it comes to the subject of aging :
What am I gonna lose,
What first ?
I don’t wanna lose this,
Whether it’s hair, vision, hearing, all sort of natural abilities,
Whether it’s beauty, grace, silhouette, muscles, good shape.
And in the meantime, while you’re so busy measuring your physical loss,
What you’re losing is soul, spirit, basic human qualities,
Your morals and values, your critical mind,
Your wits and humour, your gifts and guidance…

That is the most common trap in our focus on aging,
Hence how the process runs actually :
When you’re all about the flesh, all about the senses,
There is so much more missing that you don’t even realize is gone.
Then you lose your self and personality,
As the body fades inescapably.
