haha that reminds me of a story; The rigging shop was forever disposing of steel cable (wire rope) when it is out of date. When I was an apprentice, my work-buddy was getting into off-roading and needed some tow cable. A little dumpster diving turned up over 100' of 3/8" wire rope. Before leaving work that day, he got a couple of us to wrap the cable around his mid-section, over which he wore his winter parka, so he could smuggle it out the gate. My buddy was a pretty big guy and a smoker, and lived within walking distance of work, at the top of a pretty steep hill. I walked home with him to give him a hand, and it's a good thing I did. Half way up the hill he started breathing heavy, and soon started to struggle. The wraps of cable were constricting his chest, and the rhythm of breathing was causing a ratcheting action of the cable whereby he could exhale but not inhale. By the time he realised he was in trouble, he couldn't speak. I saw his struggle, but didn't understand at first. He was trying to flail off his parka in an absolute panic, now unable to breath. Suddenly I realised what was happening, pulled off his coat and started frantically unwrapping the cable from his chest before he passed out. Poor bugger nearly died right there on the street.
