 I saw a change in him, just my own personal relationship. Oh, yes, lots of memory problems and developed Alzheimer's and ultimately died of Alzheimer's. A lot of people die from pneumonia related to Alzheimer's, but he actually died of Alzheimer's. So, yes, you know, sometimes you, I don't know that the president has Alzheimer's or anything like that, but you do have to look for that executive functioning. You know, you've got to have that to be president. I remember your dad had some testing.
