Listen, Lala, I've flown hundreds of times, and I am always afraid. There's something in my brain that doesn't think a big metal object should be able to float on invisible air. The rumblings, bumpings and strainings are unsettling, to say the least. Even when I got older and learned something about aerodynamics, I still couldn't shake my little doubts. But I don't let that stop me. I still fly. Maybe that's all that matters--even when we're afraid, we plunge ahead. There's no other way to live, and fear gives way to joy
