Contagious LaughterOne possible reason to explain why laughter can be so contagious is that even though we laugh from all over our brain, laughter’s control mechanisms are located a long way away from brain regions that control higher functions such as language or even memory.

Perhaps this explains why it is so hard to suppress a laugh even if we know it is inappropriate, or why the brain responds even when we smile at ourselves in the mirror or simulate laughing with enthusiasm. Once a laugh is kindled deep within our brains these ‘higher function’ brain regions have trouble intervening.

Whatever the reason, here are 9 videos to see how long you can resist laughter contagion. Prepare to be very challenged!
