One fine Tuesday every human being on earth develops the ability to fly. No wings. No machines. Just up, up and away.
I suspect that only someone who is afraid of heights wouldn't want the ability to fly. And that person, after they actually flew once, might start to get over that fear.
I'd certainly love to fly. I'd love to rise up with the birds and look out at a larger view of the world.
And what would happen to the world if suddenly borders meant nothing? If the starving could fly to where there was food? If the cold and sick could fly to where there was warmth and comfort? If the oppressed and the imprisoned could simply leave? What would we do with that kind of freedom?
