FERMI AGE THEORY1

When we are born,
we know not where,
or when we will die.
How we will wander around,
while we are slowing down
in a finite medium!

Our scattering seems isotopic;
and our average lethargy,
independent of energy.
Valid is the Diffusion Theory.
In every collision, we gain
exactly an average lethargy.

As we grow older,
we have traveled more-
the slowing down is zero at a void;
and, continuous at an interface.
