Since you don't the people, you can't assume which person is which,
therefore you must be able to ask either person one question, and get the
same answer to it.  You ask 'If I ask the other person which way the
hospital is, what would he tell me?'  The honest person will will tell you
the road that leads to the swamp, since that is what the liar would say.
The liar will tell you the swamp, because that is NOT what the honest
person would say.  Then you go the other way to the hospital.

THIS QUESTION AND ITS VARIATIONS HAVE BEEN POSTED SO MANY TIMES
ALREADY!!!!
