Like it or lump it, what you profess to do says a lot about you; it's widely accepted, for example, that accountancy is synonymous with dull.
When I was studying physics, admitting to it was social suicide. It didn't take me long to realise that in normal (i.e. non-physics) company, saying that I was a physicist** was guaranteed to stop the conversation.
Perhaps surprisingly, being an applied mathematician in Bath didn't have quite the same effect, though I suspect that this was because everyone else in Bath also studies maths and I was therefore lulled in to a false sense of security. The response I generally got was "oh, another one then" followed by a roll of the eyes. At least the conversation continued normally***.
But now, it's all come good. When someone asks me what I do, I sometimes even enjoy responding with "Aircraft Simulation", As lines go it's not a bad one**** and if that doesn't clinch me the crown of most eligible bachelor in the village, I don't know what will.
*My favourite book as a child, by Richard Scarry, had this title.
**which I was, apparently.
***Unless I was talking to someone who was socially inept.
****Surely it's up there with "is your dad a baker? Because you have nice baps" and "sit on my lap and we'll see what comes up".
