After a sound sleep, I switch on The BBC World Service in the early hours. A Dutch scientist is talking about self-healing materials. The materials are charged with micro capsules which when stressed spread and self- repair. Asphalt, paint, concrete can all be treated in this way. Fully awake I begin to take notes on the post-it pad by my bed. Even now 12 hours later, I can decipher the gist of the story.
An old friend with an ever lively mind tells me on the telephone that she "cutting on the things to be interested in".
