I used to be scared of heights, not much use in my job, (painter+decorator). Soon got used to it, as long as i set the ladder im happy enough, still like someone holding it though. But my height worries pale into insignifigance to the work my dad used to do, building electricity pylons all over europe, no safety harnesses, (they held you back in his opinion), everything was free climbing with just your tools in a belt pouch, the highest tower he worked on was in germany, 700ft high, i have some old german newspaper articles with pics of him and his gang, pity i cant understand german though.
