Here's a puzzle that I recall from my childhood (so it's old).
You're in a room with two exits (and no idea how you got there). The exits appear to be exactly the same except one exit leads to safety and the other to certain death. Beside the doors stand identical twins. One always lies and the other always tells the truth. You are allowed one question to one of the twins to help you decide which exit to take. What do you ask?
Note that this puzzle assumes no suicidal tendencies 🙄 (i.e. you're looking for the safe exit)
