I stuck with standard practice, most polls will use age cohorts from 18-65, and place the ages above and below that into a less than and more than option.  Generally age forms a bell curve.

I don't think we have anyone less than 18 here, nor do I believe that we have more than a few that are more than 65.  I can only think of of 1 or 2 who might be older than 65.  How old is Fran?  I thought she was in her 50's.  Everyone else pretty much falls in the 20-50 category.

And I'll give my consent to any government that does not deny a man a living wage-Billy Bragg
