As beautiful as it is, and all the amazing things I've heard about how warm and hospitable the people are, the reason why I won't visit is because of what can go wrong.
Of course a vast majority of peoples trips go perfectly fine, but with some bad luck you could find yourself in a substandard hospital,a political pawn, a scapegoat for a crime or worse. Personally the possibility of a trip going catastrophically wrong, although slim, are enough to dissuade me from going in the foreseeable future.
Just my $0.02
I would avoid riding in cars and taking showers then.
If you are worried about dying from statistically more probable stuff than visiting Pakistan that is.
