You are walking down a path when you come to two doors. Opening one of the doors will lead you to a life of prosperity and happiness, while opening the other door will lead to a life of misery and sorrow. You don't know which door leads to which life. In front of the doors are two twin brothers who know which door leads where. One of the brothers always lies, and the other always tells the truth. You don't know which brother is the liar and which is the truth-teller. You are allowed to ask one single question to one of the brothers (not both) to figure out which door to open. What question should you ask?
Ask "If I asked your brother what the good door is, what would he say?" If you ask the truth-telling brother, he will point to the bad door, because this is what the lying brother would point to. Alternatively, if you ask the lying brother, he will also point to the bad door, because this is NOT what the truth-telling brother would point to. So whichever door is pointed to, you should go through the other one.

Paul is 20 years old in 1980, but only 15 years old in 1985. How is this possible?
The years are in B.C., not A.D. as you probably assumed. Based on the system we use to number the years, the years counted down in B.C. (but they weren't counting backwards back then).
