...it's just that I've decided that a nearly foolproof way to avoid plummeting to a horrible screaming death is to avoid them where possible.
For example, you could not march me to where this hiker is standing at gunpoint. You might get me to inch out there on my tummy, eyes scrunched shut and limbs a-quiver if I really really believed you might shoot me otherwise, but to stand out there? Hellz no. You could fall off! I'd rather take my chances making a play for your gun.
My palms get sweaty just looking at that picture.
Oddly, heights don't bother me much in an airplane. Maybe it's that lack of any continuous visual connection between my point-of-view and the ground that robs it of its sense of perspective.
