Remember when I was doing the Tall Ships Race. Had to climb the mast to fix the rigging in the middle of a muther of a storm. The guy who was guiding my safety rope told me to watch out for ‘disco leg’ after 30ft. Gave him a funny look, but sure enough, after the first set of seperators my knees were shaking so much, I looked like an acomplished elvis impersonator. Heights are scary.
