Let me join in: I am a mining engineer and I must admit that I like my work very much and it has given me exciting moments (and still gives some).... I think that I became an engineer because I like tecnology and I choose mining because it sounds very adventurous and romantic ... and ... yes, indeed, it is.

Now, for statistical purposes, I could recall what profession my slaves were into:
the first became a lawyer and worked for the national railways;
the second ... well I don't know as I lost track
the third became archeology assistant at the university of Rome
the fourth studied to become a bibliothecarian (hope the term is correct),
the last, caroline, was a housewife, though she was a college graduate.

As far as I know, none of them browses the net, so would never meet them on a forum like this ... If I try to guess what they and other slaves I met had in common, I would pinpoint a solid cultural background and this seems to apply also to most dominants I met on the scene.
