“I would like to die peacefully with Thomas Tallis on my iPod before the disease takes me over and I hope that will not be for quite some time to come, because if I knew that I could die at any time I wanted, then suddenly every day would be as ­precious as a million pounds. If I knew that I could die, I would live. My life, my death, my choice.”

Terry Pratchett, who died recently at the age of 66, eight years after being diagnosed with early onset Alzheimer’s disease
