Why is yawning contagious? The brain and mirror neurons

[AshThEpSYcHo]

Than why sometimes i yawn and not seeing or hearing someone, than when i flip my head i see a person behind me yawning and him not seeing me or hearing me... (When i yawn i don't open my mouth i just stretch my eardrums)

Speaking of mirror neurons, I was totally feeling that monkey's pain in the beginning

[BrookeAlexandra02]

i yawned so many times while watching this video

[CyXBeAtZ]

Reminds me of Robocop, Demolition Man, Matrix & Project X.. where the training is repetitious video segments of war and killing or whatever the base of the movie was and at the end of the training, they mirrored what they saw in these training videos. Wild stuff!!

THE REAL ANSWER

Well due to the effects of gravity it creates a time paradox that spreads yawn particles from one person to another. Yawn particles are formed when you enter a neumatononical sleeping state. A neumatononical sleeping state occurs when a person is affected by the space time continuum. Thus resulting in the rapid transfer of yawn particles. Which in turn makes you yawn...

So true! When I watch SYTYCD I just want to get up and dance along.

[MissPsychStudent]
