@dailymail: A Japanese mattress company is turning sleep into a competition, offering about $14,330 to the participant who performs best during a 90-minute sleep challenge in Tokyo this October. Contestants will be monitored for factors including sleep depth, quality and how quickly they fall asleep, while organizers introduce deliberate distractions to test how well they can stay asleep. The event will also hand out special awards for deep sleepers and contestants with distinctive sleeping positions. #sleep #japan #tokyo #competition #viral
