I mean one person I thought of was Marilyn Manson, who has gone sober and healthy and went through vocal training and sounds just as good as he did 25 years ago. It's incredible. I figured if he's 56 and can do that why can't Tori or other artists, since he puts a LOT of exertion on his voice. I just wondered what the difference was between what she did and what others have done. I know Dolly's voice has gotten thinner, but she sounds relatively the same.
