Disappearing singer Amy Winehouse has been diagnosed with emphysema, according to her father. "'The doctors have told her if she goes back to smoking drugs it won't just ruin her voice, it will kill her,' he was quoted as saying in the Sunday Mirror. 'The doctors have said that if she had continued the way she was going she could have ended up an invalid-she wouldn't have been able to breathe.' He added: 'She's got emphysema. It's in its early stages, but had it gone on for another month they painted a very vivid picture of her sitting there like an old person with a mask on her face struggling to breathe.'"
