I AM writing this letter as I recover at home after heart surgery. First of all, I would like to thank all the surgeons and doctors for a job well done. Also, the nurses on the Cardiac Intensive Care Unit, the Heart Failure Unit and Ward 31 at James Cook University Hospital, Middlesbrough, for looking after me following my operation, and to my customers – I will be proud to clean your windows as soon as I am fit.

Peter Evans, Darlington.
