Human Cog

The human cog,
the corroding link,
in the massed machine,
slowly turning on and on,
unrelenting in its task,
until its time to replace an old part,
re shaped re forged,
there is always a new system,
a new part of the endless machine,
to pull along in another endless task,
till one day we fall from our place,
left where we fell,
no longer needed or wanted,
just another broken part,
in the machine of life
