"When adults say, 'Teenagers think they are invincible' with that sly, stupid smile on their faces, they don't know how right they are. We need never to be hopeless, because we can never irreparably broken. We think that we are invincible because we are. We cannot be born, and we cannot die. Like all energy, we can only change shapes and sizes and manifestations. They forget that when they get old."

~John Green (Book: Looking for Alaska)
