James Stewart, where are you?

I get vertigo incredibly easily. Standing on a step-ladder will do it. Therefore today has been traumatic. First of all going to a fairground (Joypolis) with the daughter and having to endure her strange sense of fun. Then, later, watching the magnificent - but terrifying - film about Philippe Petit, the Frenchman who was the Man On Wire between the twin towers of the World Trade Center, back in 1974. It's terror, but mercifully not as we know it these days.
