I look at it this way the human body is is constantly changing and adapting so I don't believe we reach a point at which we can say 'ok, that's as far as I'm going to be right again'. I think it becomes harder as the progress slows but if you tackle each issue individually then you can still see improvement and it doesn't take much to make a big difference to quality of life. However, the psychological impact of a head injury cannot be under estimated and ignored, I know for me this has been the hardest thing to deal with on my own.
