The brain is a valuable resource,
It's a powerful tool at its optimum.
Imagine it is similar in performance
to a car engine.
you give it a tweak
if there is a systems failure,
the mechanic can repair, adjust,
and bypass damaged areas;
so too with the brain.
It may never return to full capacity,
It may need constant refuelling, and spare parts galore.
And after all, on the outside the bodywork is undamaged.
There is nothing to stop it reaching its full potential
The mechanic can achieve this with a car,
But he's not yet met the brain........
