At the end of every episode, we take a moment to thank an Unsung Hero: someone who’s not on the staff of the show, but who went above and beyond in helping us out. In recent weeks, we've been asking you to share your own examples of someone who's made an impact on your life. This time, Josh Gitelson of State College, Pa., recalls a small gesture of kindness from a stranger on a plane.

Do you have a story of an unsung hero you want to share with our listeners? Tell us about it! Please email us at [email protected], with the subject line "Unsung Hero." For some guidelines on what we're looking for, go to hiddenbrain.org/unsunghero.
