Yeah, I find that odd too. I wonder if there's some kind of algorithm that downloads what the hockey articles link to, and thus a lot of what's called "Hockey" could be things like the articles about the cities that the teams are in, articles about the physics of water freezing, ect.
I recorded a late night conversation with my dad a couple months before he died of dementia and cancer. It was moreso him ruminating on his life's regrets. It was a lot of word salad but there was a genuine feeling there that he had squandered a lot of his time. He kept saying that he "fell off" somewhere along the way.
I'm very sorry for your loss. I'm very fortunate that he didn't have dementia so he could articulate some thoughts. I hope your story will push others to act before it's too late.
