Ring of Fire

"When life forces us to do something impossible an explosion happens inside the body. A rush of hormones blasts through us, making us stronger, making us faster. Biology overrides fear and that makes the impossible possible. Nobody wakes up thinking: "My world will explode today. My world will change." Nobody thinks that. But, sometimes, it happens. Sometimes, we wake up, we face our fears. We take them by the hand. And we stand there waiting, hoping, ready for anything."

- Meredith Grey
