virgin wool comes from the sheep that r;un the fastest

Well, Nunca Bill, it sounds as though that's probably a pretty accurate definition...! given what you went on to say. Sounds as though virgin wool is simply wool that was actually shorn off a sheep? (as opposed to collected from other sources)

and thanks for your explanation too, emanuela - now I know what kind of olive oil I want to get! (cold-pressed extra virgin. Must...resist...temptation...!)
