I talked with my mom,
scarlet1... my father begins his pulmonary therapy this week. If it *doesn't* work, he will have 3-4 years (still better than the 1-3 year estimate earlier). If it succeeds in arresting the further development of the disease, he could go on indefinitely. (crossed fingers) He actually managed to play a few holes of golf last week. Yay!
I still have issues of my own to deal with around my father, and I may as well go ahead. Anything could happen, anytime. But at least it feels less imminent. :)
