I've just read this article - and bought the book. Ian Taverner loved cooking, but when he developed a painful debilitating condition, he lost his ability and his interest, and almost his family too. www.bbc.co.uk/news/disability-56536589
"Ian spent years "existing" until the NHS referred him to the Bath Centre for Pain Services' pain management programme - it was the last form of treatment available to him. As he started to move forwards with his pain, Ian thought about the things he used to love and how they might help - cooking was the first thing that came to mind. " He has now written a cookbook, "Cookfulness", specially for others in similar circumstances.
I don't suffer from fibromyalgia, like him, but the book is full of useful tips and hints, and recipes from the very simple to the ambitious, adapted for the disabled.
The hardback version is £14.95, but the Kindle edition is only 0.99p at the moment!
