Your ears secrete more earwax when you are afraid than when you aren't.

While cerumen (earwax) production can increase with stress as part of the general fight-or-flight response, the claim that ears secrete 'more' earwax specifically when afraid is not well-established in medical literature. Earwax production is primarily continuous and varies by individual, not clearly documented to spike during fear states. This appears to be a common trivia claim rather than a rigorously verified medical fact.
