Have a Fear of Heights?

[innerSpaceman]

I used to have a very debilitating fear of heights, but cured it (for the most part) by doing things like zip-lines and skydiving and standing on scary edges whilst reminding myself that I was no more likely to simply fall over (or have things somehow rise out of my pockets) when standing on solid ground adjacent to a sheer drop than I was when on solid ground in the midst of other solid ground.

That said, I don't like rollercoaster lifts that climb too high, and I'm more comforable on a mountain peak than a skyscraper cap.
