"Frequently I am asked if I will take my life when I have a terminal illness. My answer is: "I'll wait and see." If my dying is bearable, the pain well managed, and my self-control and dignity are not damaged, then I shall hang on and die naturally. But if I am one of the unlucky few who suffer abysmally, then I shall make a quick exit. This book is intended for readers who think much the same as me."
