There’s an old story about Yuri Gagarin, the first man in space. The story goes that when he was up there, alone in orbit, looking at the earth, completely alone, he began to hear this ticking noise coming from somewhere. The noise continued for minutes, and then hours. He frantically searched through the whole cockpit, tearing panels out of walls, but he couldn't find it. There’s nothing he could do. So he decided, after it all, that the only way he would be able to make it out alive was to fall in love with the sound.
