@windwalker I think I need to quit thinking along the lines of 38 and remember I'm 78. I used to clean my whole house in a morning (small house) and now I can't do it in a week. I'm still frustrated because my doctor doesn't think I should be this tired with as few areas in my lungs. This week should be the heart valve test. We haven't worked our way to my legs yet??? Maybe it's my legs refusing to move. I know it's not funny but if I don't laugh I cry.
