That is a bit extreme. My point is more like, if unable to walk is 0 and being Michael Flatley is 100, there is a 20 or 40 level of leg clumsiness which you can see either as "normal" clumsiness or a neurological disability, neuromotoric illness, and my point is that humans tend to react radically differently to which interpretation is being used. A normally clumsy guy gets laughed out of the dancing course, the guy with the disability gets sympathy, pity and points for just trying. My struggle is trying to figure out a consistent and logical approach.
