Day 170: Yawn



"A yawn may not be polite, but at least it's an honest opinion."

Even looking at a picture of a yawn has been making me yawn. By the way, apparently yawning is contagious due to the ancient, deep, and subconscious roots of empathy and social bonding. 55% of people who witness a yawn will yawn within the next 5 minutes. Yawns don't become contagious until around the age of four. I thought it was interesting that autistic children are less likely to catch yawns than other children. The more severe the condition, the less common the behavior of catching yawns gets.
