To relieve stress I walk - fast and alone. Usually I walk to the heath which is about an hour from my home in West Hampstead. I like to know where I'm going so I do the same walk every time. I have a very bad sense of direction, which I think has to do with having moved countries.
I walk more or less whatever the weather. I don't go out if it's pouring, but if it is only drizzling, I'll put on a hat and go. I find writing becomes more difficult the more I do it because I am becoming more ambitious about what I write. Going to the movies also helps me to relax and sometimes I have been known to play the odd computer game.
It is pretty unhealthy sitting indoors looking at a computer screen - which is why I started taking walks. It's one way of straightening the back. I don't like talking as I walk. I'll say 'Hello' to people I know as I pass by, but I am not the kind of walker who likes to have a conversation. I don't like doing any exercise with other people.
Walking is my way of turning off, of not having to think about words. Sometimes it empties my mind and sometimes a thought that I have been looking for will pop into my head without effort. Sometimes I go back to my computer after my walk and the words come flowing out - but unfortunately I can't set that up.
