I hope thats a pack and not a dog yer holding...

It used to give me the willies to get near an edge, even for the first three years of technical climbing I couldn't look down, so I looked out, and on rappel I looked straight ahead, once I walked right of an overhang that I didn't see coming. Rapping off overhangs is an art. You go horizontal and even lower then simply hop off, swing under and your head should clear.

Now I can stand on a 1 inch ledge 500' up and look straight down and feel nothing. My body has learned to trust my head.
