Mark,
my swimming teacher had a bad concussion which lasted for about 7 months about 5 years ago, she was behind on her school and spent a miserable year. Yet she now claims she is 100% and never had a set back since.
I feel you have a tendency of telling people that this is something you have to deal with the rest of your life, that downturns WILL happen. I am confused. Most people I know don't seem to agree and I really do hope you are wrong on this
After all if I knew that for the rest of my life I won't be able to fly/run/exercise/drink/listen to loud music (concerts) for the next 10 years of my life, I would make a more dramatic decision.
I really really hope that there is such thing as 99% recovery. And if any of you know of these it would be really great to let us know.
Thanks
J
