When I was younger (10 or so) I was told that I would eventually lose all of my hearing. From that point on, I worked on reading lips. No lessons, just being ever vigilant. It is exhausting and not very reliable for me. I find that these many years later, it is harder and harder. I am losing so much on daily conversations at home that I generally stay online or read books. Out in public, I try to write notes, but most people are not receptive to that. I have taken my netbook with me to use Word or Notepad, but still, they are not receptive.
When having to read lips for various nationalities it gets harder as well as the various dialects for regional differences.
