"You know your tailbone? It used to be a tail. That pink part in the corner of your eye? Your third eyelid. The appendix used to help us digest tough foods. Now it does nothing. The story of our evolution is the story of what we leave behind, what we’ve discarded. Our bodies only hang on to the things we absolutely need. The things we no longer have use for, we give up, we let go.
Why does it feel so good to get rid of things? To unload? To let go? Maybe because when we see how little we need to survive, it makes us realize how powerful we actually are. To strip down to what we really need. To hang on to only what we can’t do without. Not just to survive but to thrive."
— Meredith Grey (Season10, Ep.15-Throwing It All Away)
