The top is dead skin that always gets replaced
So nothing is exactly the same from day to day
And underneath that is the living blood and cells
But you can’t see them unless you cut yourself
Then there are the muscles if you go down deep
There you got control unless you’re crazy or asleep
Then you got your bones. They complete the list
And you’re gonna need them in case you want to make a fist
Down to the molecules where much more is revealed
Then your atoms, then you’re in the sub-atomic field
Where there is no certainty just laws of probability
Then there is the biggest part that nobody can see
Next time it happens I know you’ll understand
When somebody tells you, “I know that
Like the back of my hand
