Life long fear of heights.
Tried to over come it in my early twenties by learning to rappel and top rope climbing. Worked for a utility contractor at the time and went through lineman training class as well.
Was able to climb with some confidence but never able to over come the fear that made me prone to panic if something went wrong.
Panic while climbing will get you killed.
Mis-step and 18' fall ended all efforts.
