From Martin Savage
Simon Thompson mentions that parachutists yawn before they leap (20/27 December 2014, p 38). I’d imagine this has less to do with focusing on a task, and more to do with opening their Eustachian tubes in preparation for the imminent rapid change in air pressure.
He also neglected to mention the main reason some men yawn: it’s an excuse to get our arm around a girl’s shoulders.
