@farmerman,
Farmerman, he has known for about a year. His doctor wanted to wait to do anything because Bob's blood pressure was so high. Now that it's down, she sent him straight to the pulmonary specialist.
Now I would like to ask for help strangling (gently) him because he forgot to tell me all this a yeas ago. There is was, desparately worried, not knowing that there was an answer that could be addressed in time.
I'm still thinking of some painful and long lasting punishment. I might not let Sally dog stay with him all the time. Nah, that would also be punishing Sally. She, silly dog, is devoted to him.
