According to Douglas Adams, the secret of learning to fly is "to throw yourself at the ground and miss."
On some mystical level, this may be true, but it has never worked for me any of the times that I have tried it. Luckily I have only tried it in the figurative sense.
And then of course there is the symbolism that links flying to sexuality. If you believe what people say about themselves, many have experienced great success with methods of sexual exploration that resemble throwing themselves at the ground.
This is something I can't speak to from experience, because the risks seem too high. Guess I'd rather live with regret than end up as the kind of person who gets his fifteen minutes of fame on the Jerry Springer show, and is genuinely surprised to learn that he is being brought on stage to hear bad news.
