It's a video of a steeplejack from the U.K. named Fred Dibnah. He was an amazing character. After watching that video check out the one that shows how he erects the scaffolding to dismantle the chimney.
Fred used the term "No Fear" several times in this old video from decades gone by, which I find ironic. He was the epitome of someone with big brass ones. Being quite a philosopher, in other videos he talks about the causes of some of the problems in society today, and how he thought they could be solved.
