Towards the end of July I plan to do a gruelling forty mile trek across the Pyrenees. I decided, in part, to do this walk as a challenge to raise money for the Cornwall Air Ambulance. This has brought some interesting responses. For example, my son agreed to sponsor me, but suggested that next year I could sponsor him to lie on a beach towel for two weeks off the Amalfi Coast. It was an astute remark. There is indeed something strange about doing something for yourself but asking people to give to charity at the same time. I am doing it because of my work as a psychological therapist.
