Pains have been taken by the media to say that Mr. Kitterman has no medical issues, but I'm wondering whether he has dementia and his family either just won't admit it or aren't aware of it. It's also possible he suffered a small stroke which caused him confusion. Whatever — I hope his family gets him to a doctor for a thorough examination and testing.
A friend of mine had a stroke at home. They found him out wondering around in the neighborhood. His wife had been at work at the time. He did not know where he was or where he lived. Just saying.
