Vertigo

I'm not a huge fan of heights, I get that giddy head-swimming sensation whenever I'm near the edge of something more than ten feet off the ground. So it was very brave of me to venture up to the top floor of the building I work in to take this photo - looking down 8 out of 9 floors to the bottom of the atrium.

I do have to confess I kept one hand on the railing whilst taking this picture, despite the fact there was absolutely no danger of me going over the edge!
