did you yawn? You know you want to. Hard to resist the word. YAWN. Annoying isn't it. Why is yawning a such an addictive reflex unlike say blinking or coughing? I've read it's so catchy because it's a herd instinct. Wikipedia compares the sympathetic yawn to howling in wolves... That explanation doesn't really do it for me but I haven't found a better one. Other facts: the first yawns are in the womb; contageous yawning doesn't usually occur in babies until around 12 months; pandiculation is a word meaning a yawn + a stretch; yawning is contagous between species; men yawn more than women.
