I have had some prosthetic leg-related incidents that have been unfortunate but not entirely unexpected. I’ve set off a couple of times without checking that my left foot is touching the ground and ended up on the floor.  I’ve trapped the leg under a restaurant table and dragged the table and chair with me towards the exit to the consternation of the other diners.  My blood pressure has soared dangerously in response to a friend telling me that she had just seen Heather Mills running along the seafront and “no one would even know she had only got one leg.” I’ve pulled a muscle in my neck while trying to tie my shoelaces.  What I had not anticipated was crushing my left index finger in the knee joint of my prosthesis. Now that did hurt.
