I agree, Willy, these falls can be really bad. We hired an off-duty firefighter to clean our chimney one time about 20 years ago (he had a part-time business as a chimney sweep). The family room where the chimney is is just one story, but with a steeply pitched roof. He got up there and was doing fine until we were looking out the window and saw him come down, feet first. He was in bad shape, so we called 911. The FD medics ragged him unmercifully while they packaged him and took him off (not a good show, in my opinion). Turns out he had broken his right hip, and was off the job for more than six months. Hope this guy fared better.
