I agree with lots of what you are saying Greg, all except the bit about the solution being simple!Fabras appears to get astounding results for sure, and I think the emotional & psychological element in FD has been seriously underestimated from a therapeutical standpoint, but I have a problem seeing FD as merely a 'bad habit' like biting your nails or something. I think your average neurologist would have kittens if they read that.
For people whose fingers are badly twisted up the notion of 'just getting on with it' doesn't make any sense.
