I guy I know (who has no idea I'm an alcoholic) was telling me about his father who has late stage liver disease due to years of alcohol abuse.
His father has less then two weeks to live. He has a lot of fluid accumulation and swelling is his abdomen and legs and he can't walk well, has memory loss and confusion, has bleeding gums when he tries to eat, has irregular breathing, a racing heartbeat, and a few other things.
His dad is 58, so his years of heavy drinking probably knocked a couple of decades off of his life.
