I really, really don't like heights. Frankly, I made a conscious decision not to grow any taller than my current size because of it. So you can imagine the cold sweats I got when I saw what happened at Chicago's Willis Tower.
According a a news report, "A spokesman for Willis Tower told the Chicago Sun Times that
what cracked was a protective coating on the glass structure and not the
glass itself. The spokesman said the protective coating worked exactly
how it was supposed to work."
You'll forgive me if I stay here holding onto my desk.
