Interesting...My Balance is atrocious, as is pretty much all fine motor skills and a lot of the big ones. I reckon I am dyspraxic, which is related to ADHD (and dyslexia, and autistic spectrum apparently, but I'v never shown signs of autism - i don't even like cars).
I am so unbalanced and clumsy I was banned from woodwork, cooking, sewing, painting, physical education and electronics.
