And when you're constantly fighting post-head injury dizziness on a daily basis it's really important!

Way back after my concussion, and my Doc referred to me as one of his "dizzy blond patients" - I was signed up for a jazz dance class. I had a real hard time doing stuff, like pirouetts and even floor exercises that I used to be able to do pre-injury. After talking to my doctor, my dance instructor, and the head of the dance department, the compromise was that I would audit the class. That way my instructor was not pressured into trying to grade me, and I wasn't working for a grade, it was PT. As it turned out my dance instructor was interested in teaching "community" dance classes anyway, so having a "handicapped" student in his class, and working through the balance issues was a personal challenge for him.

But on a bad day when I'm tired, my balance is more likely to be off, and after 25 years, I can still feel where I got hit in the head. But I think I'd be worse if it wasn't for the dance classes.
