I've been watching TV and i've seen this commercial about 100 times in the last week..

At a height of 1,500 feet above the Little Colorado River Gorge, Nik Wallenda will walk on a wire that is just 2 inches thick. While traversing the 1,400-foot-wide gap between the cliffs, Nik will have to adjust to sudden wind gusts of over 20 mph with no safety tether attaching him to his line.
Why...?
