Ian,
You are such a massive inspiration to anyone suffering with illness that all I can do is stand in awe. You took all the steps necessary to enhance your health and you have openmindedly accepted other trains of thought. All would benefit from your stance on things (as far as thinking about it deeply and taking a real inspiration from it).
As for years left, I think that quality is important, so important in fact that quantity becomes almost insignificant. Faced with death, each moment becomes something large - so much larger than before. However, having faced my mortality in some smaller sense than you have, I still wonder at your perspective, considering that you have been forced to face yours in a much more profound way,
I'll PM you,
Sirona
