A company is conducting a survey on people's leisure time and hobbies.

A blind man is asked if he has any hobbies.

"Sure do", he replies, "skydiving".

"Excuse me sir", ask the pollster, "but with your handicap, could you please explain just how you manage to skydive"?

"No problem, I just stand in the doorway with my hand on the ripcord and the jumpmaster pushes me out".

"But how to you know when the ground is approaching?

"Well", the blind man replies, "I have an overly developed sense of smell. At about 300 feet above ground, I can smell the grass and the trees and I know the ground is coming up".

"But how do you know when you're about to strike the ground so you can bend your knees and be ready to roll"?

"Oh that's easy", he replies", just before I reach that point the dog's leash goes slack"!
