Years ago a guy fell from a mile up. He landed in the backyard while a family was having a barbecue. He bounced twice, got up, and staggered away while the family stared on in shock. He got off with only a concussion.
He said that after he figured out that neither of his chutes were going to work that he closed his eyes and kept repeating the phrase "I am a limp noodle" over and over, completely relaxed, until he hit the ground.
I read this in a magazine, but I can't remember which one (it was at least 7 years ago).
