This poem is just another reminder of the inevitable. There comes a moment when a person starts thinking about it and then he never stops: the idea keeps turning and turning in his mind. It is as if we are being prepared for what will come sooner or later because "Life and Age is a process due" as you rightfully put it. I remember once writing a poem (it fits here so let me cite it):

And all the things just keep on their course,
And every thing returns to where it belonged
After fulfilling purpose of its life and worth,
Cause meaning of creation is to live and go.
Our destination is to keep alive, endure the same,
Meet our final stage and thus fulfill the end,
And leave a trace for generations still to come,
Who’ll feed on legacy of ancestors that passed,
And find their sustenance in it and thus survive.
And like a day that comes and night that follows in its wake
This unabated drive for life will never change,
For thing that matters, being essence of our life
Is waiting in the line for our turn to come
To bring fresh blood to earth and then to die
Without complaint, but thanking for our time.
One generation passes thus and then another comes,
But earth abides forever, Ecclesiastes writes.

Many thanks for sharing this poem!
