Today at the doctor's office, I noticed that he almost wasn't able to stand up. I didn't know what I was going to do. He's been having difficulty with this, but today I noticed how difficult it is-really hard to do on his own power. I help him as much as I can, but don't know how much longer. I think he is getting weaker in his legs. He has copd, emphysema, major heart issues. I think we will ask a doctor what to do about it. Today we went to get an X-ray to see if he had liquid in his left lung.
