You are one cell in a warm sea. Eat, and you grow. Grow, and your body answers what
you have been doing — a hunter grows a mouth, a grazer grows cilia, something that keeps getting
bitten grows armour. Nothing here is chosen from a menu. You become what you did.

Things bigger than you will hunt you. Things smaller than you
are food. Which of those you are is the whole game.
