Silly question: What’s the first thing you think of when I refer to Sheffield?

I never saw the film, just clips from it at school, though I don’t expect life is quite as bad up there as it would be in a post apocalyptic world. I’d actually forgotten it was set in Sheffield. The only thing I know of or think of about Sheffield, other than steel a long time ago, is cancer treatment. My cancer is rare enough that there are only two centres in the U.K. that treat it: one in London and one in Sheffield. I can’t really afford to stay this close to London anymore (I’m in the Home Counties) and I have little quality of life here because after I pay my bills I’m left with about £20 a month for hobbies, clothing, cosmetics and savings, but moving any further away will make treatment days even more debilitating, and my only other option is moving to Sheffield to get treatment there. I do not know anyone who lives in Sheffield. I have never been to Sheffield. I do not know anything about Sheffield. So far I have managed not to move there, but I’m not sure how much longer I can stay here. I guess I’ll be interested in the replies to this post. Maybe it wouldn’t be a bad move, and I’m just being a semi-rural Hertfordshire/London snob.
