I was thinking about it just now, and you know how people say "I grew up listening to/watching <celebrity>?" Well, I honestly couldn't think of a time from the year I was born until I reached adulthood that Jackson wasn't on the radio/television/movies in some fashion. And I don't mean in the gossip rags, I mean actively producing new work. From The Jackson 5 straight through to Dangerous, I literally grew up watching and listening to this guy.
Not entirely unexpected, though. You can't do the clinically insane things he did to his face and body and expect to outrun the side effects forever.
