A roll player would say, "there are those that Do and those that read about those that do." :-)
Or, as my friends say: there are those who read about Elves, there are those who believe in Elves, there are those who roleplay Elves, there are those who write about Elves, and there are those who believe they are Elves.
(I'm in categories1, 2, and 4. I know my limits!)
