Sometimes it is hard to be certain
What is real and what is not
I have been looking for certainty
But nothing is certain
In the limbic system
Deep within the temporal lobes
There are two small almond sized groups called the amygdala
In the amygdala there are certainties of a sort
The amygdala is the heart
Of our instinct
Instinct that develops and sharpens through experience
It's in the amygdala
That when we call it
We instantly decide
Whether to run away
Or to stay and fight
And in that decision there is no doubt
Instinct is primitive
Instinct is certain
To my Instinct I believe
I'm somewhere in London I think
I'm somewhere in London I think
I'm somewhere in London I think
I'm somewhere in London I think
