It's perhaps worth pointing out that this new NHS number, which was to 
provide an ID number for everone, available to any government 
department, is entirely different from the one that used to grace 
medical cards, and was apparently not used at all by anyone (except 
perhaps the department in charge of storing GP records for 6 months and 
throwing 20% of them away every time you change GP). I for one would be 
interested to know what is happening to the new NHS numbers, we 
certainly don't seem to have them locally.  This is, I think, actually 
on topic.
