You've been hit by a bus and you don't want to make a fuss about it?  Well, this is quite a common condition - basically, you're dead.  As far as I am aware, there is no cure for this.  You could try taking a couple of paracetamol, but I think that you're unlikely to notice any improvement.  Still, look on the bright side: you won't have to get up and go to work tomorrow morning, will you?

Of course, as soon as a patient becomes what we doctors call 'deceased', they are no longer our responsibility.  Sorry, you're on your own now.  You may think this is a rather callous attitude to take, but hey, it keeps the waiting lists down.
