Could be. He also definitely needs to quit smoking. That hoarse smoker’s voice of his tells the story.
I’ve never heard him speak. I’ve seen a photo or two of him with a cigarette, but didn’t know how habitual that was. But the stick and booze do go together.
I still enjoy a VERY occasional cigar (4 this year...). and my glass of bourbon on Saturday/Sunday, with a glass of wine at meals, but that’s it. He needs to learn to practice moderation (though it may be too late for that...).
