That's when I realized that I have very mixed feelings about this thing called walking. Walking in the City, in particular, makes me very aware that I am not very good at it. I am a rock, the rest of the crowd is the stream. It's slow. Right now it's also painful. It can cause spikes in inflammation. It attacks my sense of competence (as a professional person, not doing this basic skill well....). More than anything else it is simply difficult.
Is it still worth doing? Yes, I think so. It allows me to go places, and do stuff that would be harder to do from a wheelchair. I say this with complete sympathy for those who have made the other choice.
