Maybe it's like flying. I never flew before - or something like that, but I know, somehow I know it, I feel it. There's no other sensation to compare with it. It's like flying... I don't have knowledge on air resistance, I don't have the slightest ideia of what would happen in my stomach in a freefall, but I'm pretty sure that what I'm feeling is something like that. It must be. It has to be. It is. I'm flying.
