In regard to the damage having been done, I've read that the body begins to heal itself within days of quitting smoking. Sure there is permanent damage at this point, but I'm sure some of the deterioration could be reversed somewhat. Personally, I like the husk on her voice circa TI. And I don't mind the sound of her voice at all on T'LOG. The tempo of some of the tunes is more bothersome to me than her voice.
And, totally off the subject--I'm not a fan by any means, but has anyone else noticed Whitney Houston lately? She looks and acts like she's smoking crack and it's kinda scary. Poor thing... Ken
