I have echo Matt's comment about "talking shop"; as a former Civil War reenactor, I sometimes will be asked why I am not reenacting that period any more -- and the answer is because I worked at a Civil War Battlefield as a park ranger for three years (and still do on the odd weekend), and I didn't want to do it on my days off! :mrgreen:

Granted, I haven't lost my love of books, even though I am a librarian!
