No, no, no, no. I chickened out of a gorge jump in South Africa and just watched my DH and two others do it. Heard the longest OMG ever as one was jumping.
Right with most of you and have always been extremely uncomfortable with heights. Most of my 40+ year career has had me required to work underground. I've worked in holes 50 and 60 FT deep. I've been as deep as 300 FT below the surface. Have never had any issues with claustrophobia or any fear working underground. Can't get me on much more than a 10 FT ladder!! Lots more people killed in trench and tunneling cave-ins than from falling off a ladder. Convince my brain of that!!!! :>)
