Sorry about the vagueness of the question, but I have several issues here.
As a person with acrophobia knows, there are varying degrees of fear of heights. Mine kicks in at about 30 feet or so. Some things I’ve noticed that strike me odd are the following:
Why am I not afraid of being in an airplane?
Why is it that I can stand on top of the Empire State Building, which has a fence around it, and feel no fear, but could never comfortably stand on the edge of a two story building with no fence/wall?
Why can I easily walk along a trail with a drop-off to one side that has an incline sloping away from me, but even the thought of getting near a sheer drop petrifies me? In fact, I can’t even go out on an overlook platform with rails/walls, if I can’t see the slope underneath, and forget ANY situation where there may be an undercut bank lurking under there.
What is it about bridges? I can drive across a bridge with guard rails, but will not even attempt one that doesn’t (we have several of these in Alaska).
Why is it that walking across a bridge, even with rails, can make me break out in a sweat? Particularly if it is over water. And forget those godawful bridges where you can see down through them to the water. NO friggin’ way am I setting foot on THAT!
Why is it that merely watching someone approach a sheer drop makes my stomach do flips, when I couldn’t possibly be in danger? My children can relate this problem eloquently, as in (name of child), GET AWAY FROM THE EDGE OF THAT (river, bridge, cliff, etc.)!!!
There are probably other situations, but I curious as to the mental process that says "This one is okay, Chefguy, but don’t you dare go out on that one.
