Twin Chairs from "Who Wants to Be a Millionaire?"

Origin
“Who Wants to Be a Millionaire?” is a game show that offers cash prizes for answering multiple choice questions of varying difficulty correct. The maximum prize attainable is usually a million units of the local currency. The show relies on suspense over speed while answering and has only one contestant compete at a time, who is told the question before deciding whether to answer.

Effects
When a person is sitting in each chair they are bound there until 15 questions are answered. Every question the 'contestant' gets right drains the 'host' of life and revitalizes the 'contestant', while getting a wrong answer has the opposite effect.
