Well cannot comment on the picture, but many people won't for example cross on the road over that French tidal power station thingy, mainly due to the height. From my point of view, I'm a bit the opposite these days. It seems now I cannot see, heights bother me less.
The only snag of corse is that as we all know, its not the falling which is the issue, its the sudden stop at the bottom. Many of us are a lot more brittle than when we were younger so it does pay to be careful.
Also memory can be far more faulty as one ages, so the fact that you actually removed that nice place to place ones foot while movingfrom shed to garrage roof might not be obvious until its far too late.
