Perhaps this is a silly question, but those fit well in this forum, so why not?
I’d definitely rather have a broken heart, for two reasons:
I’ve had a broken heart before, but never a broken leg. Better the devil I know and all that.
I’m a very practical person, and while with a broken heart I may not want to do anything, I would not be prevented from doing things in the way that I would be if my leg were broken.
