I am sorry to hear about your wife. I hope that your prediction does not come to pass, and that she has many years left. I have learned that nothing in life is certain. Neither the beginning, nor the end.

On the other hand, this quote troubles me given the context.

Count your blessings, name them one by one
Count your blessings, see what God has done

I do not believe God has done this. I believe in tough times, and luck both good and bad. I hope that good fortune smiles on you, Pat. And I hope God helps us cure these terminal diseases.

Marc
