I watched a friend succumb to dementia, It's not a pretty sight, they try to think and can't; it frustrates them and in the end stages, they get angry because they can't force the thought. Biden is close to the end stages. won't be long now. They don't die of dementia, they die from shit like falling down or being unable to swallow their medications/food. If you are fond of someone, it's sad to watch, If it's Joe Biden; it's going to be epic. He's been a piece of shit for four decades.
