As I sit down to write this article, I am very much aware that today is the anniversary of the death of my mother. A strong-minded, intelligent and, above all, proud woman, her greatest fear as she became increasingly physically frail was a loss of dignity, something she had witnessed in the slow demise of her own mother.

From middle age onwards, she wrote me detailed letters describing what she would and would not tolerate as she got older, and instructing me, the only doctor in the family, to do everything possible to help her to die peacefully when the intolerable became manifest. Sadly, the law forbade such measures and, despite receiving excellent care in her failing years, she suffered much of the indignity that she most feared before passing.
