You just yawned because I said the word "yawn," didn't you? That's because yawning
is contagious as fuck thanks to mirror neurons in your brain that make you copy other people
like a goddamn sheep. Why do we even yawn? Scientists don't know for sure, but the leading
theory is brain cooling—yawning increases blood flow and brings in cool air to regulate
your overheated brain. Boredom, tiredness, or seeing someone
else yawn triggers your brain to say "copy that shit." You're probably yawning right now.
