someone i met told me that he had trouble with his liver and kidneys, they checked his liver and the doctor told him that it was 78% percent shot and if it got to 80% it wouldn't regenerate (not sure how true this is) the doctor told him he had to stop drinking, of course he didn't and soon he was urinating blood and finally stopped so he said. I've heard him talk about drinking again since then. it's quite a disease..
