A blind skydiver was being interviewed about his hobby and asked how this was accomplished.
He explained that many things were all done for him. “Others make sure that the parachute is properly harnessed, and I am placed in the door and told when to jump. Even my hand is placed on the release ring for me”
“But how do you know when you are going to land?” asked the interviewer
“I have a very keen sense of smell,” explained the skydiver. “I can smell the trees and grass when I am 300 feet from the ground”
“But how do you know when to lift your legs for the final arrival on the ground?” pressed the interviewer
“Oh, that’s easy,” grinned the man. “The dog’s leash goes slack.”
