00:00Don't read this next word.
00:05Yawn.
00:08Hmm.
00:13Too late. Your brain just copied someone else without asking you.
00:19Meet your mirror neurons.
00:22Brain cells that fire not just when you do something,
00:25but when you just watch someone else do it.
00:34When you see a yawn, these neurons light up like you're the one yawning.
00:39That's why yawns by yawns spread in classrooms, on video calls,
00:44even just from reading the word yawn enough times.
00:51It's not tiredness spreading.
00:54It's your brain's empathy circuit,
00:56quietly sinking you with the people around you.
01:01The closer you are to someone emotionally,
01:03the more likely their yawn catches you.
01:06It's contagious because it's connection.
01:09There it is.
01:09Probably not.
