YES THIS IS TRUE. I HAVE ASTHMA AND I NOTICE THAN I TEND TO YAWN MORE WHEN MY BRONCHIAL TUBES ARE TIGHTENED AND IT'S NEVER A GOOD YAWN...KWIM? WHEN MY BRONCHIAL TUBES ARE NOT TIGHTENED I DON'T YAWN AS MUCH AND WHEN I DO IT'S A FULL YAWN.

I yawn all the time. I just yawned a second ago. The more tired I am the more i yawn. The more bored I am the more I yawn.
