We’re all walking in a straight line

So we all finish up where we began

Secretly I believe my atoms are mine

Hang onto these bits of me as long as I can

Read a science book and now I’m aware

That each and every carbon bit

Is only me for a fraction of a hair

I’m jealous of my emancipated particles I admit

Because that’s less of me to drag along

New parts replace my old pieces

Guess I’ll keep walking my whole life long

Until my straight line race ceases
