I do exercises - four every day of the week to increase balance, and four more three times a week, to increase strength. This is part of a program started years ago in Australia called Stepping On.
One of the daily exercises is to walk an imaginary tightrope.
This has gotten me fascinated by actual tightrope walkers - the people who risk their lives, and sometimes lose them - such as Karl Wallenda of the famous Wallenda family, who fell to his death at age 73.
And then there is the true story of Philippe Petit, who (illegally) walked a wire between the two towers of the World Trade Center, the same towers that so tragically were destroyed by terrorists on September 11, 2001. I warn anyone who is still disturbed by images of the towers not to watch the following video.
Our world is so different now, in those 41 years since this walk happened.
Since I started the exercise program in May, I've walked that imaginary tightrope daily. In my kitchen. At work, during lunch. At my mother in law's house. Outside. I can walk that imaginery tightrope now without holding onto something - but not for long.
I was warned, it would be a long road.
Now I read Philippe Petit's story, and marvel - he is older than I am.
Where did I go wrong? Will I ever be able to walk a straight line? (I don't think I would ever dare a true tightrope.)
In the meantime, every day, I dream of better balance.
