no doubt imo his commentary deteriorated gradually. i still liked him, especially with billy. he was at his best pre ~2015.
my grandfather passed three days ago. he was healthy aside from his dementia, but the dementia likely caused him to not aknowledge/communicate that he had fallen and hit his head a month ago. the brain bleeding was a month old when he got to the hospital and nothing could be done. worked at a longwave/shortwave radio central for 45 years and every single one of his workmates got dementia.
