Hilary Lister had had the difficult conversation with her husband -- a few times in fact. The quadriplegic had finally made the decision to end her life, had prepared to say goodbyes to Clifford and the rest of her family.
"It got to a point where I evaluated my life," Lister told CNN. "I had to decide whether the space that I take up on the sofa [which unable to move she had done for hours and days on end] was still worth inhabiting.
"I came to the conclusion it wasn't. I was at a very, very low point.
"I knew if and when my condition got any worse I would end my life. That was a decision myself and my husband were both aware of. You don't make that decision on your own, you have to prepare yourself."
"It was like 'gosh, I've found a reason to live.'"
That was 11 years ago.
Since that Damascene conversion she has sailed single handed across the English Channel, circumnavigated Great Britain and most recently sailed the 1,500 kilometers across the Arabian Sea from Mumbai to Muscat, her first proper offshore expedition.
