Okay so I was with a friend who is a doctor, and I went on a bit of a deep dive of Bon Jovi with them and he made a comment that made a lot of sense to me.

Does Jon Bon Jovi have dementia?

This decline isn't just not hitting high notes. Jon is literally not in time with the music, at all. Say what you want, but it is shockingly bad. It's like he doesn't know how his own songs go. I can understand a declining voice- but to play entire shows where your timing is off for well over half the show? Whats going on here?

My friend seems to think he might have dementia or some sort of brain issue. Even on stage he looks off, doesn't even look like he knows how to move around or dance or anything.

Has this been discussed at all? I can't seem to find anything on it.
