i remember reading a really cool article years ago on a tribe of american indians, seems they were the only ones who could stand the heights on some of the buildings that where mega high. From what i recall they had a construction crew that was completely made up from this tribe and they some how genically proved they had no fear of hieghts. Anyhow some of the photos that acompanied it was just mental..... i would be wearing a parachute at all times, but these guys were onthe outside of a building just going about there business..
I couldnt do it, i have a fear of failing from something breaking off
What happens when they tower corrodes ? imagine if the bolts snapped off.............
