You are traveling through a Forrest inhabited by 2 tribes; the Truth Tellers and the Liars.
The Truth Tellers always tell the truth and provide a safe haven for travelers during the night while the liars (who are fierce cannibals) never tell the truth and like nothing better than chowing down on lost travelers.
It's getting late and you come to a fork in the road; one path leads to the truth tellers village and the other leads to the liars village.
There are no signs to point you in the right direction, but there is a man from one of the villages who you could ask for directions. The only problem is you don't know if he is a truth teller or a liar.
You can only ask him one question. What question do you ask to find out which path leads to the truth tellers village?
