Cocoro Scanner, a Japanese toy that shows your mental state

When the light is green that's normal, yellow is bewilderment, and red is agitated.
I don't know how real this video is, but there's an old man married to a much younger woman. A lady who asks her boyfriend about getting married. They have a monk read a nude magazine. There's a transvestite. A lot of it seems set up, but it'd be interesting if these were actual random people.
