Man, 52, With Rare Condition Collapses From Laughing

A 52-year-old father of three from the United Kingdom has to keep a straight face when watching sitcoms, as any sort of laughter can cause him collapse, London’s Daily Mail reported.

Mike Hallowell was diagnosed with narcolepsy, a sleeping disorder that can cause a person to fall asleep suddenly, and cataplexy, a sudden loss of muscle tone, which is triggered by an emotional outbreak.

Hallowell said his condition began about six years ago when he had oral surgery.

Hallowell said soon after the surgery, he was watching a sitcom, which prompted him to start laughing – and that’s when he fell over.

"When I fall, it happens really quickly," Hallowell said. "I just crumple, and then I’m done."
