You just reminded me of the famous photograph of a man sitting very high up on the structural steelwork of the Twin Towers eating his sandwiches. He certainly didn't look as if he was bothered by heights.

The only time I was ever nervous of a height was on top of a building with a reinforced glass roof, so that you were looking down through the glass roof to several stories below. I didn't much like that. It felt very unnatural to me - as if I was going to fall straight through the glass.
